Priority.
Technical field
The invention mainly relates to the energy managements by recuperation of heat, more particularly, to for being by heat recovery system
Large scale industry place provides system, computer-readable medium, program code and the method for the energy management of enhancing.
Background technique
The reality of industrial economic effect, the limitation of global energy supply and environmental protection is holding for all industries
Long focus.Most people in World Science circle is thought, leads due to discharging various greenhouse gases (greenhouse gases) into atmosphere
The global warming phenomenon of cause has a negative impact to world environments.
There are mainly three types of sources for greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O).Upper one
In a century, the CO2 being discharged into air in the world has been sharply increased.The industrial revolution and natural resources (such as coal and petroleum)
Exploitation be CO2 discharge be made that very big contribution.From the point of view of greenhouse gases, optimized for energy efficiency is not only used for reducing energy
The fast tracking method of consumption is measured, and needs to reduce greenhouse gases/CO2 discharge based on energy.
In decades, optimized for energy efficiency only addresses only the energy efficiency of independent processing unit.But from 80 years
Since for later period and the nineties initial stage, variation has been happened.Energy efficiency not only for independent device/unit, and
The large-scale place and industrial field of heat exchange network system will be used also directed to subsystem, system, commercial plant and now/future
Institute.
The problem of heat exchange network synthesis is a multivariable various dimensions optimization, wherein overall network driving distribution depends on
Each stream mode and the recuperation of heat minimum of each hot-fluid are close to temperature.These variables may consequently contribute to the quantity of determination unit, external form
(shell) and heating facility and cooling facility and its demand for mixing facility.Using traditional folder point (pinch) technology, this
Kind Multi-variables optimum design problem reduction is single argument optimization problem --- for the global minima of each heat-treated stream of described problem
Close to the optimization of temperature (Δ T_min).Although theoretically this method can be used for any scale, other people still through
Direct process internal integration between the hot-fluid and cold flow of equipment and be only used on each autonomous device.In process level
It in this way, and should be proved to reduce the discharge of energy consumption and the greenhouse gases based on energy very successfully.Pass through
The specific minimum optimal set and improved matching technique close to temperature (Δ T_min_i) of research stream is designed system to, by
The system of the update of a present invention described herein or the assignee of multiple inventions exploitation provides further optimization.
Emanation (emanation) and its evolution of pressing from both sides point analysis technology comprehensive about process due to pinch technology,
Directly integration is only process internal integration.Integration is considered as unpractical by industry between direct process.It is this for using
The arguement of integration includes: that the process that need to be integrated can have different starting time and shut-in time；These processes may be in portion
Divide on load and works；The condition of these processes may have seasonal variety；Due to the change of process timetable and management philosophy
Change, compared with the fund cost integrated between indirect process, the fund cost of utility system, heater and heat exchange network can
It can will not reduce；If integrated, the disturbance in a process can involve another process, so that the process is difficult to control；
The controllability that distance verses time/speed sluggishness influences the course；Geographic distance between each process will will lead to a large amount of of pumping or compression
Energy consumption and will may require that pipeline be laid with, pump and compress relevant fund cost；Liquid is transported from a danger area
Safety is influenced whether to another danger area；And the fear for leakage etc., this is universal for Facilities Engineer.This
Outside, lack the systematic method integrated between the process for handling extensive place and industrialized regions, and traditional mathematics is compiled
Journey model cannot cope with large-scale problem, and many facilities may relate to the industrial area of oversight.Therefore, although direct process
Between integration potentially for saving energy and reducing greenhouse gas emission be very favorable, but this method is not still practical so far
Design and transformation applied to large-scale industry site.
As a result, it was recognized by the inventor that needing such system, computer-readable medium, program code and method, it is used for
It provides between being located between the multiple equipment/process being adjacent on reason position and carrying out directly integration while still considering indirect process
The selection of integration, to be optimized to wasted energy recycling and reduce greenhouse gases.
The method integrated between current process is the indirect method using buffer system.The buffer system can be steam
System (in most cases) or thermal oil system.Research circle and industry are all obtained mutually is fitted with using the indirect method of vapour system
The improved folder point methods and mathematics programmed method answered.About the use of steam, the pinch technology of early stage is to aiding in determining whether
Total place heat integration of steam generation level influences, so that different processes is integrated indirectly.But some research people
Member opposes that, because the generation of steam must be completed on fixed temperature levels, this will lead to mistake using steam under some cases
The opportunity of integration is spent, the steam generated in most of chemical complexs is also used to power, this to drive device
Dynamic and heating steam is nearly impossible with the demand exact matching heated with process, therefore, it will usually cause exhaust and/
Or the application that large quantity of air is cooling.In addition, by waste heat boiler put in processing with from a terminal recycle waste heat and
Ignore path of the steam in entire facility, block or industrial area and its end point, this is not optimal.In addition, being permitted
In more hydrocarbon processing facilities, due to worrying the leakage and corrosion of hydrocarbon side, to cooling treatment steam
Do not recommend to generate when being heated or use middle pressure steam and/or high steam, therefore is usually regarded as one kind and forbids matching.
Therefore, some researchers oppose to use steam as buffer, but agree with using thermal oil system.
About the use of hot oil, research circle and industry are all obtained and are adapted with the indirect method of thermal oil system is used
Improved folder point methods and mathematics programmed method.But hot oil is supported to fail to be mentioned that better than the researcher of steam, it removes
Except the desired energy saving target of realization commonly required a large amount of hot oil routes, the lower heat exchange coefficient of hot oil liquid is led
Heat converter need excessive surface area, need to add more units, every route needs a large amount of starting heaters and/or
Aerial cooler, etc..
Therefore, it agrees with the researcher of steam and agrees with the researcher of hot oil not advocate by while analyzing or using
Thermal oil system and vapour system are integrated between indirect process to provide.Therefore, it was recognized by the inventor that lacking such a method,
Following problems can systematically be found out: when thermal oil system, vapour system or said two devices are provided based on thermodynamics or based on warp
Help the preferred embodiment learned.In addition, it was recognized by the inventor that without any existing method simultaneously using integration method between direct process
The integration method between indirect process；There is no any conventional method for extensive problem using integration method (example between direct process
Such as comprehensive refining, petroleum chemicals industrial area and Chemical Industry Park)；And correspondingly, simultaneously without any conventional method
Using the direct method and indirect method for using both thermal oil system and vapour system.In addition, it was recognized by the inventor that not any
Conventional method is in view of being directed to the wider direct integration of community field/domestic environments except industrial circle.
Generally speaking, although industry seems direct whole in (for example, between several equipment) integration between agreement process
Conjunction method more efficiently and in energy consumption and greenhouse gas emission based on energy can be saved more, but it is not yet
Practical application, before the process of each embodiment of one described herein invention or multiple inventions designed, there is no appoint
What, which is directed to, is presented the systematic method of the integrated system of this ability to large scale industry association.Therefore, industry for a long time with
Come exist for such system, computer-readable medium, program code, method unmet needs, allow to use
Family is concerned with thermodynamic efficiency according to policymaker, is the balance between business efficiency or the two, by utilization steam system
Integrated between the direct process of system and/or thermal oil system and/or be integrated between process indirectly enforcement with and to energy recycling system into
Row synthesis.

In: utilize synchronous integration and system specific design and operation modification for any number of system (for example, facility, equipment)
Energy object is determined, to obtain optimal reason in the case where considering non-thermodynamics limitation and not considering the limitation of non-thermodynamics
By energy efficiency.
Step 2 includes: to determine block in all possibility of the specific modification of process and the specific Δ T_min of stream using energy object
[Qh] and [Qc] in acceptable user-defined range is found in combination.Figure 15 is shown for improving energy between process
Δ T_min is selected in the synchronized process of integration.In this example, a graphic user interface is provided, user's typing is allowed

Control, or by such as United States Patent (USP) 7, automated process described in 873,443 is controlled.
In addition, Figure 16 is shown for improving Δ T_min selection inside the synchronized process of energy integration between process.Show at this
In example, compared with the conventional method for using identical Δ T_min (10 ° of K) for each hot-fluid, pass through the heat to typing in table
Stream respectively using one group of stream it is specific minimum close to temperature value Δ T_min_i={ 8,12,12,8,8 } ° K, come so that value be 78 add
Thermal effect realizes 5% reduction with consumption Qh.It is clear that using one group of stream it is specific it is minimum close to temperature value Δ T_min_i=8,
12,12,8,8 } ° K does not significantly change the reduction amount of heating effectiveness consumption Qh.
Step 3 includes being determined to the folder point section in problem scope with a folder point position control process.Figure 17 shows
For improving design and operation modification between process inside the synchronized process of energy integration.In this example, it is shown at 81

From start from folder point temperature stream supply/inlet temperature region, block, facility, equipment, unit or stream, be by problem respectively
Folder point control in range is for current minimum close to the region of temperature, block, facility, equipment, unit or stream in calculating.
If there is more than one process, the sundry item of the stream supplied/started at said temperatures is flowed or be expressed as, then may be used
That of control folder point position is found out close to temperature or its supply/start temperature by the minimum of each stream of elimination.
If folder point position is moved, corresponding stream is that controlled the position of folder point temperature.If pressing from both sides point
It sets and does not move, then can repeat the process, until finding out control stream.Step 4 include policymaker select or find out heating effectiveness,
One or more expectation energy target levels of cooling effectiveness or both effectiveness.Policymaker can select minimum heat at 91
Effectiveness consumption perhaps selects minimum cooling effectiveness consumption at 92 or is selected between two kinds of facilities according to his/her purpose
Balance.The selection indicates the extensive problem process status in each stream/process/facility/block/region modification.
If having selected minimum cooling effectiveness to consume Qc by automatically analyzing as shown in figure 18, finger can readily determine that
Show the optimal processing condition of minimum cooling effectiveness consumption Qc.Specifically, Figure 18 shows such scene: policymaker selects minimum
Cooling work effectiveness Qc and the minimum thermal effectiveness at the minimum cooling work effectiveness Qc consume Qh as primary goal.
That is, the not theoretic minimum value of thermal effect consumption value Qh, realizes the best of the target with minimum cooling work effectiveness
Energy value of utility.Figure 19 shows opposite scene, and wherein policymaker has selected the processing for leading to minimum heating effectiveness consumption Qh
Condition.

Δ S_P_all+X={ ∑ Q_out/T_out } all- { ∑ Q_in/T_in } all equatioies (1)
Δ S_P_A+x1={ ∑ Q_out/T_out } A- { ∑ Q_in/T_in } A equation (2)
Δ S_P_B+x2={ ∑ Q_out/T_out } B- { ∑ Q_in/T_in } B equation (3)
Δ S_P_C+x3={ ∑ Q_out/T_out } C- { ∑ Q_in/T_in } C equation (4)
Wherein X=x1+x2+x3,
Equation (2)+equation (3)+equation (4) equation (5)
Equation (5)-equation (1) equation (6)
Using composite curve shown in Figure 24 to Figure 26, if compared with being integrated between direct process, by independent and indirect
Integration causes the generation of entropy increased between process, then the exemplary application of the result of equation (6) will be the identification entropy and produce
Raw increase, as follows:
Δ S_P_all+X=2610/540-460/1060=4.4 (1)
Δ S_P_A+x1=1440/780-460/1060=-2.28 (2)
Δ S_P_B+x2=300/540-250/780=0.235 (3)
Δ S_P_C+x3=2310/540+1690/780=6.445 (4)
Δ S_P_A+x1+ Δ S_P_B+x2+ Δ S_P_C+x3=4.4 (5)
(5)-(1)=0.0 (6)
Result is shown herein, in the specific condition, among A, B, C after its process internal integration
Process between to integrate the result integrated between obtainable efficiency and direct process identical.It should be noted that being only for this
Case research can lead to identical result using above-mentioned vapour system.If allowed and community's (power supply for heating and cooling down
And steam) integration, the electric power generation in equipment is needed or feasible, or as used in previous example, LPS
Header saturation temperature is higher than 780R/320F, and equation (5)-(1) difference will not be zero, and heating effectiveness will be higher, produces in equipment
Raw electric power can be less, cooperates with community and providing a possibility that heating and/or cooling and ability for it can decline.
Stage Ι, experiment test D
Experiment test D includes: the block 64 tested using the influence to steam header quantity and condition to energy consumption,
The block provides a kind of method of the influence of steam header and condition for energy consumption for testing specified quantity.
As it is following will describe as, compared to only use integrate between immediate system required for energy, only with
Bigger energy consumption usually (" most of the time ") will be will lead to using integrating between the indirect system of steam.Using between steam
It connects and integrates the theory of behind and be, such as any one of one " facility " (multiple) stream source/mono- (multiple) hot-fluids are all available
In generating steam close at temperature in specific vapo(u)rous temperature and reasonable minimum, then in specific vapo(u)rous temperature
It is integrated with reasonable minimum (multiple) chute/cold flow close at temperature with the steam in needs another " facility ".
For example, it is assumed that steam header there are three us, we can generate under following saturation temperature and consume shown quantity
Steam power:
| Vapo(u)rous temperature (T_sat) | It generates (10^4Lb/h) | Demand (10^4Lb/h) |
| T_sat1 | 5 | 10 |
| T_sat2 | 4 | 3 |
| T_sat3 | 6 | 8 |
| T_sat4 | 2 | 9 |
| T_sat5 | 5 | 7 |
| T_sat6 | 4 | 2 |
As shown in Figure 27 to Figure 31, in order to whole using the DIRECT ENERGY between the heat source and cold source in the facility studied
It closes and realizes identical energy consumption (heating and cooling), system will may require that six steam headers as shown in figure 27.Such as Figure 28
To shown in Figure 31, compared with the achievable energy consumption of directly integration for using additional steam header, three steam are used
Header (it is the standard convention in most of industry) will will lead to the increase of energy consumption, and the following additional money
Golden cost.
The energy object integrated between stage II-directly process and integrated between process indirectly is found out
II process of stage includes the application of the shared calculation block 66 of thermic load between system.According to an exemplary embodiment, it uses
In finding out the shared first step of thermic load can include: use example the following steps as shown in the table carry out the temperature within the scope of construction problem
Spend task image:
Step 1 includes determining energy integration region, block, facility, equipment and process considering the problems of carry out system
Justice.One example of the processing step is as Fig. 5 to Figure 14 description.
Step 2 includes: to be configured to each region, block, facility, equipment, process and stream and steam header and hot oil line
The cold recombination line (CCL) on road；Step 3 include: using the Δ T_min of insertion be configured to each region, block, facility, equipment, into
The hot recombination line (HCL) of journey and stream and steam header and hot oil route.It is noted that for the purpose of construction, steam connection
Case and hot oil line exchanger have the minimum close to the 1/2 of temperature of each hot-fluid for their transmission loads.It is described below
The illustrative methods of one construction CCL recombination line and HCL recombination line.Advantageously, method below can be used for analyzing any amount
System in any number of stream, wherein the system can be defined as multiple regions (for example, 4 or 8), block, facility,
The cluster of equipment, process or unit.
For illustrative purpose, consider such a industrial site: it has, and there are four regions, and have been received and be used for
Find out the information of the quantity of block in each region, facility, equipment, process, unit and cold flow.In order to reduce the complexity of the problem
Degree, each region of processing requirement only has a CCL line.Assuming that industrial site the first system (can be a region or
Block or facility or equipment or process or unit) it is made of a cold flow, second system is made of a cold flow, as follows:
| Stream | Ts | Tt | FCp |
| C1 | 20 | 250 | 0.10 |
| C2 | 139 | 500 | 0.15 |
CCL will be then drawn, will be configured to as shown in Figure 31.Since cold flow C1 and C2 is in 250 ° of temperature and temperature
It is overlapped between 139 °, therefore the FCp of the temperature range has the efficiency value of 0.25W/ ° of K (0.10+0.15).
Step 4 is described to step 11 for energy integration problem between exemplary system shown in Figure 33 to Figure 37.
For the exemplary issue, it is assumed that there are three system, each systems to have as provided in following table for industrial site tool
Operation stream parameter；For all hot-fluids, Δ T_min=20 ℉；MPS saturation temperature is equal to 450 ℉；LPS saturation temperature etc.
In 350 ℉.
| Region # | Stream type | Ts | Tt | FCp |
| A | Heat | 500 | 250 | 25 |
| A | It is cold | 200 | 500 | 23 |
| B | Heat | 500 | 100 | 15 |
| B | It is cold | 100 | 450 | 17 |
| C | Heat | 450 | 250 | 20 |
Figure 33 shows an exemplary temperature task image, has global energy target between the system of overlapping.In step 1
To in step 3, by problem definition the added each cold flow for being used for each region and hot-fluid each recombination line or temperature
Among line.In step 4, point is pressed from both sides to best/expectation in problem scope and folder point position control process positions.Show at this
In example, folder point position controls the hot process flow that process flow is region A or region B in 480 ℉, they, which all have, is located at folder point
The initial temperature set.
In steps of 5, force/forbid direct matched region, facility, equipment, process and stream to be defined to any.?
In step 6, the part of " folder or more " is plotted on an axis；For CCL, region or equipment or process are in alphabetical order
From the axial right drafting；For HCL, from the axial left drafting.Equally, in step 7, the part of " folder or less " is plotted in one
On a axis；For CCL, region or equipment or process are in alphabetical order from the axial right drafting；It is axial left from this for HCL
It draws.
In step 8, it using the expectation Δ T_min of insertion, inputs in vapor level and is drawn at 101,102 in each user
Horizontal line, and temperature folder point 103 on, folder point temperature near draw horizontal line (if present).Step 9 packet
It includes, when representative area/region includes multiple streams of (its value is not suitable for this exemplary issue) as shown in figure 32, at every
Arrow is drawn at each variation of the FCp of CCL and HCL and its value is placed near lines.
In step 10, thermic load 104-109 is write into each of (or being loaded into) folder or more (multiple) region or (more
It is a) top of block or (multiple) facility or (multiple) equipment or (multiple) process, thermic load 110-115 is write into (or being loaded into)
Folder point each (multiple) region below or the bottom of (multiple) block or (multiple) facility or (multiple) equipment or (multiple) process.
Step 11 include: " superfluous thermic load " 121 is alphabetically write folder or more each of (multiple) region or
Superfluous thermic load 122 is simultaneously write into folder point in the upper left corner of (multiple) block or (multiple) facility or (multiple) equipment or (multiple) process
Each (multiple) region below or the lower left corner of (multiple) block or (multiple) facility or (multiple) equipment or (multiple) process, with
And " short thermic load " 131 is write into the upper right corner of those of the above object of folder point and short thermic load 132 is write press from both sides put with
The lower right corner of those of lower object." superfluous thermic load " is the load for needing to recycle by energy integration between system, otherwise will
Need the cooling work of problem site pinch or more." short thermic load " is to need what is provided by energy integration between system to bear
Otherwise lotus will may require that the heating work below of problem site pinch.
Figure 34 shows the surplus and shortage calculated in folder point area/region A below using temperature task image.Show at this
In example, region A has the shortage of 1440kW.Figure 35 shows the mistake calculated in folder point region B below using temperature task image
Surplus and shortage.In this example, region B has the shortage of 250kW.Figure 36, which is shown, calculates folder or less using temperature task image
Region C in surplus and shortage.In this example, region C has the shortage of 4000kW.Figure 37 is shown each region
Thermic load be entered into superfluous 122 typing field of thermic load and short 132 typing field of thermic load after Figure 33.
Stage II-is directly integrated between process and the energy object integrated between process indirectly finds out the stage, whole between hybrid system
Close matching process
According to an exemplary embodiment, find out the shared processing of thermic load may include to for directly match process,
Temperature task image within the scope of the problem of connecing matching process and mixing matcher is analyzed, such as, it may include shown in following table
Following steps:
According to step 1 to step 3, as previously described, cold recombination line and hot recombination line are constructed, and to problem
Point is pressed from both sides in best/expectation in range and folder point position control process is identified.In step 4, on temperature task image to adding
Thermal effect with or (multiple) theoretical expectation energy object level of cooling effectiveness or the two be marked.According to step 5
With step 7, folder point above section and the folder of temperature task image or less part are depicted.
According to step 6, by using take directly and/or indirectly mode, using the matching plan of steam and/or hot oil,
The thermic load to recycle from region, block, facility, equipment, process is found out, to reach desired target.Property is matched according to the example
Set, by make result without departing from calculated Qh and Qc in the way of, selection meet folder or more " surplus " and " shortage " with
And one or more matching schemes of folder point " shortage " below and " surplus ".Alternatively, policymaker can determine he/her due to
Such as fund, operability or other reasons and want the energy level abandoned.Designer/policymaker can using using emulation and
The analysis tool of other economic models, to assess for the purpose of saving the energy opposite with fund cost and other processing targets
The scheme of may be selected, works as so that whether all possible energy indicated by final decision saving is worth, or only saves part energy
Amount, portion of energy is more value added works as if it is saving, then determines which part abandoned.The calculating of surplus and shortage in temperature task image
Can give/guide decision-making person determine any part abandoned.For example, for example, policymaker is optional only whole by equipment C and equipment A progress
It closes, rather than integrates equipment C and equipment A and equipment B shown in such as Figure 38.
That is used if there is the selectable scheme that can reach (multiple) expectation energy target according to step 8
The scheme that can be merged between folder or more and folder or less a bit.For example, when carrying out integration assessment, if shown folder
Or more each equipment between direct integration require equipment A and equipment B are integrated, then to guarantee to for directly integration
The assessment of option additionally considered combined so that folder point equipment A below is same as equipment B.
In order to reach desired (multiple) energy object, for non-thermodynamics consider, it may be necessary to and/or it is expected into
Row indirect matching.The processing is similar with what is directly integrated, and exception is it is not the matching for finding out optimal equipment and equipment, example
Such as, which will be dedicated to finding out the quantity of hot oil route and/or the quantity of steam header.Point for the purpose of indirect matching
Analysis can include: equipment and equipment or process and the indirect load integration of process or stream and stream are defined；For indirect integration
Load draws folder or more and folder point temperature task image below, to describe some equipment, process or stream group etc., to find out
Best match/route quantity/steam header quantity or all of which (mixing).If due to forbidden region, set
Direct matching between standby, process etc. cause advanced matching technique (such as it is hot with hot, Leng Yuleng, then the cold heat that is converted to returns
To cold etc.) be it is feasible, then at " folder point above with press from both sides or less " in process-to-process and the level/basis for flowing to stream
On reuse temperature task image, to find best hybrid plan.
Stage III- matching process and the stage for generating alternative solution
Referring to Figure 33 to Figure 50 profile matching method and the stage of generation alternative solution.The place of stage III
Reason includes the application of energy integration scheme searching block 67 and technology between immediate system.It can see from Figure 33 and Figure 37, directly
The overall heat duty integrated and (be described below) between integration or mixing process between integration, indirect process between process is in problem scope
Folder point 2610kW below in the 460kW and problem scope of folder point or more, such as shortage and surplus typing field 121,122,
131, illustrated by 132.
Energy integration scheme is found between stage III- immediate system
Temperature task image, which can also be used in the certain match selection schemes of graphic software platform, to carry out, and assists commenting what it was carried out
Estimate.Figure 38 " is matched negative between showing the exemplary immediate system found for the initial solution of an industrial site
Lotus " calculates.For example, a kind of direct matching scheme is shown in figure, it can be by the excess energy in region/equipment C by the program
Applied to region/equipment A and/or region/equipment B, and the excess energy in region/equipment B can be obtained from region/equipment C
It measures (or shortage in region/equipment A conversely speaking), and the shortage in region/equipment B can be obtained from region/equipment C
?.Figure 39 show the corresponding region between region/equipment A hot-fluid and cold flow and region/equipment B hot-fluid and cold flow/
Connection inside equipment.Temperature task image is shown, in order to realize maximum saving, at least needs two folders or less connection.Only
Any Beneficial Effect there are two the connection below of folder point should include region/equipment C and folder point region below/equipment A and B
Process between integrate.
Energy integration between stage III- hybrid system
The processing of stage III includes the application of energy integration scheme searching block 68 and technology between hybrid system.As an example,
It is assumed that policymaker has determined or has ratified that desired energy object, desired treatment conditions, desired stream are minimum close to temperature, and
And we are terminated with following 3 regions or facility or equipment or process or unit stream details:
| Region # | Stream type | Ts | Tt | FCp |
| A | Heat | 300 | 60 | 0.3 |
| A | Heat | 70 | 69 | 25 |
| A | It is cold | 30 | 300 | 0.3 |
| A | It is cold | 35 | 100 | 0.25 |
| A | It is cold | 139 | 140 | 30 |
| B | Heat | 500 | 120 | 0.25 |
| B | It is cold | 139 | 500 | 0.15 |
| B | It is cold | 20 | 250 | 0.1 |
| C | Heat | 120 | 119 | 15 |
| C | Heat | 200 | 30 | 0.2 |
| C | It is cold | 110 | 160 | 0.25 |
| C | It is cold | 200 | 201 | 25 |
For simplicity, it is also assumed that Δ T_min=10.
Figure 40 shows the temperature task image constructed according to the description provided in previous one or more chapters and sections.Pay attention to
It arrives, the smaller shortage in the C of region can be ignored as the loss in energy consumption, or can be transferred into region B's
In shortage.Shortage in " B " will be met from the surplus of " C " or " C " and " A ".If folder point in problem scope with
Under any shortage do not met from surplus, then will may require that heat medium --- this as double energy lose.Entirely
Other heating effectiveness of office's problem and cooling effectiveness will increase, and incrementss are this energy loss.This is in problem scope
Folder or more is equally applicable.In problem scope folder or more without can all be needed with any surplus that short heat swaps
Want cooling medium.
Figure 41 shows the first option integrated between immediate system.In this example, the surplus in " C " is applied to " A "
Or " B ", and the surplus in " B " is applied to " C ", the shortage in " A " can be obtained from " C " conversely speaking, the shortage in " B "
It can be obtained from " C ", the shortage in " C " can be obtained from " B ".It can see from these options, in order to realize maximum saving, need five
A connection, two of them are in folder or more, and three in folder or less.Only there are three connect any Beneficial Effect include folder point with
On " B " and folder point " A " below and the system of " B " between integrate.
Figure 42 shows the second option integrated between immediate system.In this example, by the folder point surplus below in " A "
It is applied to " B ".
Figure 43 show folder or more the indirect system using vapour system between integrate.In this example, can by MPS and
LPS is used as buffer, to be directly connected to " B "-" C " and " C "-" A " shown in alternate figures 41 and 42, to be formed using directly system
The combined hybrid system integrated between integration and indirect system between system.
Stage III- uses the final scheme of the indirect integration of (a plurality of) hot oil route
Figure 44 to Figure 46 provides the final scheme on the folder point of an indirect integration using thermal oil system.In the example
In property embodiment, in addition to it is as shown in figure 43 use MPS steam header and LPS steam header as buffer other than, can also make
With one or more hot oil routes.Figure 44 shows the determination of the heat-capacity flowrate (FCp) of each temperature range 141,142,143.
Figure 45 show with positive value with the identification of the corresponding hot oil route 151,152 of each temperature range 141,142,143, with true
The quantity of fixed desired thermal oil system.Especially showing two thermal oil systems 151,152 will provide for between execution system
The desired methodology of integration.
Figure 46 is shown, using the FCP hot oil route 151 for extending directly into folder or more, by thermal oil system 151,152
An individual thermal oil system 153 is merged into, FCP (route merged as a result) is equal to 0.097.This example is shown
The case where only needing using a thermal oil system is gone out.But as shown in the drawing, if we need two routes and we at
It is merged into function a route, then we can decline the form off-energy matter of (from 495F to 437F) with hot oil temperature
Amount, and we can lose the ability that hot oil heats cold flow.In addition, if in it is expected combined hot oil route, folder
Point is nearby and the FCP surplus of surface is not highest, then in most cases, due to the decline of hot oil temperature, it would be desirable to
More than one hot oil route.That is, the energy transmission that the temperature decline can hinder hot oil route to get it is returned
To cold flow.
The minimum number of hot oil route is two, one of them folder point or more and one press from both sides or less (do not scheming
44 show into Figure 46).But this configuration can not achieve desired maximum energy conservation.Realize the desired energy-efficient hot oil of maximum
The maximum quantity of route is five, two of them folder point or more and three press from both sides or less.
The additional enlightenment that stage III- is obtained from temperature task image
Property embodiment according to the example, the additional enlightenment that can be obtained from the use of temperature task image includes, for example, to straight
The multiple combinations for connecing and indirectly, between steam and the system of hot oil integrating scene carry out economic evaluation.In addition, such as next chapters and sections
Described, when existing, when forbidding matching, which can help to analyze for realizing the advanced matching technique of energy saving.
Vapour system and thermal oil system have their pros and cons.The exemplary configuration is that designer/policymaker presents pass
In the additional information of energy saving target.Entropy calculating can be shown, in some particular examples (for example, heating need meeting
Require to generate in the certain combined therrmodynamic systems and electric system of electric power while asking) in, will not be had using steam excellent
Gesture.In some systems, energy loss will be will lead to less than the steam header of desired amt, and if used as substitution enough
Hot oil route, corresponding (or multiple) hot oil route will not face same problem.
Stage III- is used to find the advanced matching of final scheme
Final scheme can be obtained by using the raw utility system synthesizer block 69 of central fecund, the program can root
It constrains between immediate system according to non-thermodynamics and is arbitrated between energy integration scheme between energy integration scheme and hybrid system, with
It generates and comprehensive multiple acceptable utility system topological structures out, these structures is used to provide current optimal case and pass
In the optimal case of future transformation.
It is assumed that using above-mentioned industrial site, but it is with following constraint: so that region " B " hot part under high temperature does not permit
Perhaps it is matched with cold part region " C " under high temperature, and policymaker has indicated that he/her is not desired to using new vapour system or heat
Oil system.Figure 47 shows the indirect integration scheme for using " envoy " process/stream as buffer.According to the program, be not by
The hot part B of folder or more is matched with cold part C, but hot part B is matched (step 1) with hot part C first, then will be hot
Present combination energy in the C of part matches (step 2) with cold part C.The energy that then will exceed is transferred to cold portion from cold part C
Divide A (step 3) to obtain desired energy object.Global heating tasks using this advanced matching, folder or more are identical
's.Although it is increased in region " C ", declined in region " A ".
Figure 48 shows integrated scheme between the directly or indirectly system of mixing, is applied simultaneously using envoy's (folder point 103
More than) indirect integration and directly integrating (folder point 103 or less) across each region.Figure 49, which shows to take, utilizes MPS
The complete indirect integration for directly integrating (folder or less) and 103 or more folder point of header 102 and LPS header 101.Shown in Figure 50
It is to only use MPS header 102 to execute the task of MPS header 102 and both LPS headers 101 in Figure 49.
Stage III- effectiveness entropy balance calculation process
According to an exemplary embodiment, the process for matching and generating the analysis of optinal plan can (and usually should)
It include: to analyze the entropy balance of each process or stream and their combination, for example, according to following steps shown in following table:
In step 1, policymaker determines whether industrial city utility system allows to integrate with community.
In step 2, policymaker is determining or approval system range, for example, region, block, facility, equipment, process, unit and
Stream.The entire set of each situation of one simple three exemplary system includes: { ABC }；{(A),(B),(C)}；{(A),(BC)}；
{(AB),(C)}；{(B),(AC)}.
In step 3, the entropy balance of energy integration example between whole immediate systems of three systems A, B and C is determined.At this
In example, this refers to the situation of { ABC }, and be expressed as " stage I, experiment test C " chapters and sections described in equation 1.
In step 4, determine the entropy balance of each individually internal system energy integration situation, for example, for (A), (B),
(C), three equatioies 2,3,4 are calculated.According to one embodiment, total compound song of each internal system energy integration as described above
Line can be used for the entropy production of calculation equation 2,3,4, and be used for the internal system energy integration entropy production of calculation equation 1.
In steps of 5, determined by increasing the equation for individual internal system energy integration situation (A)+(B)+
(C) } entropy balance.As shown in eq 5, value is for indicating complete about integrating between no any immediate system for the equation
The entropy balance integrated between indirect system.
In step 6, the entropy balance of the remaining composite component of each of entire set is determined.Have three in this example
Kind situation: { (A), (BC) }；{(AB),(C)}；{(B),(AC)}.For element { (A), (BC) }, by calculating (BC) first
The numerical value is simultaneously added on the entropy balance of (A) entropy balance for calculating the combination by entropy balance.
In step 7, it calculates due to each element in the entire set respectively combined in overall combination set { ABC }
The increase of entropy production caused by situation is integrated between All-in-One system, is integrated by individual internal system and indirect system with determining
Between the scheme { (A), (B), (C) } integrated increase compared to the entropy of integrated scheme { ABC } between All-in-One immediate system.In this example
In, this can subtract equation 1 by equation 5 to complete.
Increase of the indirect integration compared to the entropy production integrated between immediate system can give us and enlighten as follows: if equation
Entropy production (integration between immediate system) in 1 is less than the entropy production of equation 2+3+4 (to indirect after internal system integration
Integration uses steam or hot oil as buffer), then it is contemplated that energy integration is between forcing progress immediate system to realize the overall situation
Minimal energy consumption target and/or energy is shared with community and/or for processing application (and non-heated purpose)
Power in situ generates and/or situ steam generates.If policymaker has selected to integrate between indirect system for some reason, can
The identical calculating for being directed to equation 2,3,4 is completed using the first vapour system and the second thermal oil system.By comparison it can be found that
Since the higher entropy production of hot oil causes to be less than using entropy when hot oil in equation 2,3,4 using in equation 2,3,4 when steam
Entropy.It in this case, the use of integration between the indirect system of steam is dynamic for realizing desired energy consumption and/or original position
The better choice that power generates.
As summary, the effectiveness entropy balance calculating that property configuration carries out according to the example provides a large amount of useful enlightenment.Example
Such as, these enlightenments can be used for determining using integrating (that is, direct or indirect) between which kind of technology carry out system to realize policymaker institute
The minimal energy consumption of selection, and for confirming that other energy consumption targets determine the research conclusion of algorithm.These enlightenments may be used also
Whether industry heating and/or cooling and environment/community can be integrated for finding out (such as by using using LPS into
The Absorption Refrigerator that row heats and/or cools) and with what kind of degree/capacity progress integration.They are additionally provided
The enlightenment with the optimum synergistic of environment is given about integration method between which kind of system.Other enlightenments include determining the following contents:
Directly integration whether be it is enforceable, to reach the reduction target of specific energy and corresponding greenhouse gases；Allowing system
The optimal combination integrated between system when the direct integration between set element and indirect integration；Using steam indirect integration whether
It can lead to and integrate identical result between All-in-One immediate system；It and using the indirect integration of steam is to be better than indirect utilization
The indirect integration of hot oil, or if the two does not have any difference, to make policymaker can be according to other factors (for example, water
Availability) selection the method.In addition, the enlightenment includes the confirmation to the following contents: using the indirect whole of hot oil route
Close whether can lead to integrated between All-in-One immediate system it is identical as a result, any indirect method potential option (steam system
System or thermal oil system?) more effective for particular problem, and energy and reduction greenhouse gas are saved using being incorporated between immediate system
Body discharge aspect and can than generating more energy using integration between indirect system in terms of it is obviously advantageous.In the enlightenment
One or more also exhibit, using amount of energy described in document consumption target determine that method is not enough to be
The optimal selection of energy integration between system.
