Evaluation, so establishing multiple synthesis gas that various kinds of coal gas technology and a variety of natural gas reforming technologies are mutually combined produces simulation
Model.The plurality of synthesis gas produces simulation model and contains whole Coal Gasification Technologies and the combined situation of natural gas reforming technologies,
For example, if Coal Gasification Technology has 2 kinds, natural gas reforming technologies have 3 kinds, then multiple synthesis gas produce simulation model includes 2 altogether
× 3=6 different Coal Gasification Technologies produce simulation model with the combined synthesis gas of natural gas reforming technologies.
Step S300, simulation is produced according to effective tolerance of synthesis gas, C/Hratio, gasification furnace data and multiple synthesis gas
Model, determines that each synthesis gas produces the analog result of simulation model.With reference in specific implementation process, effective tolerance, C/Hratio
And gasification furnace data, it can be manually set by technical staff, wherein, gasification furnace data include：Separate unit gasification furnace scale,

It is inputted.
During specific implementation step S300, according to effective tolerance of synthesis gas, C/Hratio, gasification furnace data and
Multiple synthesis gas produce simulation model, determine that each synthesis gas produces the analog result of simulation model, are having by synthesis gas
Effect tolerance, C/Hratio, gasification furnace data and multiple synthesis gas, which are produced simulation model and inputted into ASPEN PLUS models, simulates
Obtain.Herein exemplified by following scene：
Scene 1：Technical staff sets effective tolerance (H of synthesis gas according to actual needs2+ CO), C/Hratio, separate unit gas
When changing stove scale and gasification furnace number of units, simulation model can be produced by multiple synthesis gas and inputs the mould into ASPEN PLUS models
Intend calculating and obtaining each synthesis gas producing the analog result that simulation model is exported.

During mould, simulation model can be produced by multiple synthesis gas and inputs into ASPEN PLUS models simulation calculating and obtains each conjunction
The analog result that simulation model exported is produced into gas.It should be noted that the scene is solution Coal Gasification Technology and day
The main scenes of right gas transformation technology coupled problem.
In addition, technical staff can also be according to actual needs, using given feed coal amount, raw natural gas amount as multiple conjunctions
Produce simulation model input data into gas, can be produced by multiple synthesis gas simulation model calculate obtain each synthesis gas produce
The analog result that simulation model is exported.
Likewise, technical staff can also be according to actual needs, by given raw natural gas amount, effective tolerance (H2+CO)

Step S400, the analog result of simulation model is produced according to basic cost data, each synthesis gas, confirms each close
The public work consumption data of simulation model is produced into gas.
Step S500, analog result, the public work consumption data of simulation model are produced according to each synthesis gas, are confirmed every
A synthesis gas produces the energy consumption index of simulation model.The energy consumption index is an important indicator for characterizing energy utilization efficiency.Its
Data source is mainly that each synthesis gas that step S400 is exported produces the analog result of simulation model and by analog result meter
Obtained public work consumption data, after these data calculate its energy by different energy reduced values, final result
For the effective gas (H of every thousand side2+ CO) energy that is consumed of product.And then simulation model is produced in energy by more different synthesis gas
Difference in consumption index shows preferable scheme to choose energy consumption.The less scheme of energy expenditure shows it in production like products
In the case of energy utilization efficiency it is higher；And the more scheme of energy expenditure shows its energy in the case where producing like products
Utilization ratio is in contrast relatively low.But energy consumption index can not be showed the scheme discharge of difference by index accordingly, it is also necessary to according to warp
Ji property index is further judged.
Wherein, the present embodiment uses energy consumption index the calculating of comprehensive energy consumption index is as follows for comprehensive energy consumption index：
In formula：E-comprehensive energy consumption；The energy kind number of n-consumption；eiI-th kind consumed in-production and service activity
Energy quantity of goods produced；piThe conversion factor of-the i-th kind of energy, is converted by values such as the equivalent value of energy or the energy.
Step S600, according to basic cost data, each synthesis gas produce the analog result of simulation model, public work disappears
Data are consumed, confirm that each synthesis gas produces the economic index of simulation model.Economic index is to weigh each synthesis gas to produce
Performance of the simulation model in terms of income, although energy consumption index characterizes the energy efficiency of different schemes, however, different schemes
Economic index generally can't make identical variation tendency with the variation tendency of energy consumption index.Main reason is that influence
The reason for project economics index shows is more, except cost of material, further includes plant investment, public work consumption and expropriation of land
Many inputs such as expense, personnel's wage.In the present embodiment, the unit price and fixed cost of the variable cost of basic cost data
Input calculate respectively after, the effective gas (H of every thousand side can be obtained2+ CO) product cost, which is economic index.
Wherein, cost of material calculation formula sees below formula.

Consumption, unit are t/h (or Nm3/h)；CiFor i-th kind of raw material unit price, unit is member/t (or member/Nm3)；A is to be effectively synthesized gas
(H2+ CO) total amount, unit Nm3/h.The calculation formula of other variable costs is similar, is not repeated herein.
In the investment of base apparatus, gasification furnace investment is invested according to separate unit stove to determine that total gasification installation is invested；Conversion,
The infrastructure investments such as purification, natural gas conversion obtain phase according to the investment data under the existing scale being collected into by fitting
The matched curve answered, and then the effective tolerance obtained in different schemes is substituted into fit equation, you can obtain each plant investment.
In device depreciable cost, the device depreciable life calculated according to 15 years, converted as the effective gas (H of every thousand side2+ CO) depreciable cost,
Formula is as follows：
M=∑s Ui/(A*8)/15
In formula, M is overall apparatus depreciable cost, member/1000Nm3(H2+CO)；UiFor i-th of plant investment, Wan Yuan；A is total
Effective tolerance (H2+ CO), Nm3/h。
Wage cost, determines, employee compensation can be according to actual conditions tune according to the staffing number needed for different device list set
It is whole.Calculation formula is as follows：
In formula, M is effectively synthesized gas (H for every thousand side2+ CO) cost, unit is member/1000Nm3；UiFor determining for i-th device
Member, unit are behaved；NiFor the tricks of i-th of device；S is employee compensation, and unit is member；A is always to be effectively synthesized tolerance (H2+ CO),
Unit is Nm3/h。
The calculating of cost of land is similar with wage cost calculating process, is not repeated herein.

The data of conjunction, analyze energy consumption index and economic index, select economic index preferable, the suitable combination of energy consumption index
As selected gasification technology and natural gas reforming technologies.In this group of technology, also due to the difference of gasification furnace number of units, its institute
The difference of the coal natural gas proportioning of generation, in different technical combinations, compares its energy consumption index and economic index, selection warp
Ji property index is preferable, and the suitable coal natural gas mix proportion scheme of energy consumption index is matched as final coal natural gas.So far, complete
The confirmation process of Coal Gasification Technology and natural gas reforming technologies, while converted according to finally definite Coal Gasification Technology and natural gas
Technology, very easily calculates the proportioning produced coal with natural gas.
