Abstract

A system for containing and transporting natural and compressed gas by ship, with cylindrical containers arranged vertically with parallel axes characterized by the fact that the said containers (100, 200) have equal heights but at least two different diameters, wherein two of the said diameters fall between 1 m and 6 m, the containers being combined in standardized modules (40), where the said cylindrical containers (100, 200) have a diameter respectively between 3 m and 6 m for a larger size of the containers (100) and between 1 and 2.5 m for a smaller size of the containers (200).

Description

For accommodating and the system of transport of compressed natural at the verifiable cylindrical receiving means that is combined into module
Theme of the present invention is a kind of for accommodate and transport the new system of the rock gas that is called as CNG by means of the cylindrical receiving means that is called pressurized container, described pressurized container for example, designed to (, exceeding under 100 bar or 150 bar or 200 bar or 250 Palestine and Israels and the pressure up to possibility 300 bar or 350 bar) and accommodating the gas that has liquid or do not have liquid under the pressure for being substantially different from external pressure.
Application
Conventionally, at sea mainly with LNG (LNG Liquefied natural gas) form or with LPG (liquefied petroleum gas (LPG)) form transport fuel gas.The former major part is made up of liquid methane and preserves under the pressure that approaches atmospheric pressure and at the temperature that approaches-170 DEG C.The latter is by butane, propane and other hydro carbons forms and preserve under appropriate pressure and approaching at the temperature of-48 DEG C.
CNG (for the initialism of compressed natural gas) is only in nearest introducing, and its constituent class is similar to LNG, but it in gaseous state and is under high pressure preserved: typically at ambient temperature (at about 15 DEG C) or at lower temperature 250 bar of (approximately-30 DEG C at), there is thus the decompression of approximately 130 bar (or up to 160 bar).CNG may contain liquid part in addition, but the major part of stored fluid is gaseous state.
Obviously, from the compression of gas volume and reduce to obtain great advantage, especially about cost of transportation is minimized.But the increase of working pressure has presented the necessity of the receiving means that makes new advances and new transport system, especially because working pressure and/or the temperature of these compression/liquefied form are considered security-related legal provisions.From the angle of strict economy, because CNG does not have LNG and the intensive compactness of LPG, therefore for the company runing in CNG transport field, the optimizer system of exploring for realizing following object becomes at all: a) by maximum volume can storage and transport gas ship be transported to safely emptying point from loading point, b) make handling procedure streaming, and c) simplify receiving means and the housekeeping operation for any valve of container.
Prior art level
Conventionally, be most commonly used to transport by sea the multiple cylindrical receiving means made from steel or composite material with various diameters and length of system use of CNG, be called " pressurized container " or PV.They are become to support high pressure and are placed on the hull interior of the ship of design for this purpose by specialized designs.
Depend on contemplated stress, the material using and production and running cost, the cylindrical receiving means the most often using has the diameter of 100cm in the time being formed from steel, and these receiving means are called as " pipe " or " bottle " in addition.They sometimes can reach the diameter of 300cm in the situation that being made up of polymer and composite material.
The typical length of these receiving means is normally constant, but length and the receiving means in board layout of portion are relevant: in the time that cylindrical body is flatly arranged, length can be slightly less than the width of hull or its part, and receiving means is laterally engaged in hull; If for example, or receiving means alternatively arranges that () is in one or more levels time vertically, length can equal the height of hull or its part.
Conventionally, cylindrical receiving means is placed with parallel array abreast, and they are fixed on the multiple intervals supporting member being incorporated into specially in hull.
The alternative long flexible tube of system imagination, its sufficiently long one section (for example, 15cm) is wound in large diameter coil pipe, and the size of described coil pipe equals the width of ship self sometimes, is furnished with vertical axis.
Therefore become known for storing and transporting with the form ship of CNG or LNG (i.e. compressive state or liquid state) system of gas in cylindrical receiving means, described cylindrical receiving means vertically or flatly and be arranged in parallel, uses the solution being incorporated in hull sometimes.The solution that uses large diameter coil pipe is also known.In addition, for the gas that does not stand high pressure, the system that the larger tank of known portion in board imagination various forms and size is constructed for a long time too.
Some special solutions are carried out the volume of the gas of Optimizing Transport after deliberation, for example, by optimizing receiving means or the coil pipe layout of portion in board.Having carried out other studies to improve and simplifies loading and unloading operation or optimize valve, manifold and safety system.Also carry out other research to optimize the cross section of receiving means or the material that improvement was used.For example,, prior art document relates to this technical scope:

In a preferred transport configuration, cylindrical receiving means arranges vertically and is placed side by side, and it is mutual shaft staggered to realize larger efficiency in transportation process.
D3 has described for preferably storing and the method for transporting fluid (especially CNG) with ship.Described method is the stack based on round coil receiving means, and described round coil receiving means holds the continuous pipe of curl rolling in inside, is filled with gas and remains under in check pressure.Compare with D2 with solution D1, the method makes likely to transport the gas of greater number, and it has simplified manifold and valve system simultaneously.In board the receiving means with coil form of portion may arrange comprise there is vertical axis, the there is hexagonal mesh description of structure of (thering is half hexagon bulkhead), described structure is especially guaranteed the high efficiency aspect the useful volume of the gas of transport.
D4 has illustrated for example have, by the specific filling of suitable liquid (, water) promotion and the method under high pressure transport and oil in reserve or gas of emptying system.The same with the described method as theme of the present invention, provide receiving means and the receiving means description of the layout of portion in board, it has certain use for defining prior art level: many cylindrical receiving means or tank are arranged vertically side by side, and for example had the diameter of 2 meters and the height of 22.5 meters, the volume of about 80cu.m and the working pressure calculating of 100 bar.
In alternative structure, tank can flatly be arranged.
D5 has described the tank with nest chamber for transport under pressure or storage liquid gas.The overall dimensions of structure is similar to the numerous cylindrical summation being arranged side by side, and has avoided the disappearance in the space of wasting between circular cross-section.Obtain in the following manner this result: weld the flat baffles of longitudinally arranging with orthogonal manner of a series of mutual axles with 3 to 4 meters (preferably 3.5 meters), and there are multiple tunnels side by side of square-section in fact by the next closed side of through transport salient angle of the whole length along multiple tanks to obtain.

D7 has described the system for by sea defeated CNG, described system is formed by the multiple vertical cylindrical receiving means dividing into groups in the unit that is called as nest chamber, each system is formed by 3 to 30 receiving means, has the manifold and the valve control system that are exclusively used in each unit.
D9 has described the metal pressure container that is coated with the composite material that reinforcing is provided.
close to prior art level of the present invention
D6 described for ship at low temperatures and under the pressure that approaches atmospheric pressure, transport the method for liquid gas, hull is subdivided into six main compartments by described method imagination, wherein each compartment has a cylindrical can and other eight circular receiving means, cylindrical can has vertical axis, there is the diameter equating with maximum available width, eight circular receiving means have less diameter, be called as wing tank, it occupies untapped space between main tank and the main tank on main tank side.
Each in wing tank is sealed by fluid-tight bulkhead.
Even if do not relate to transport and the relative needs of CNG, especially interestingly, by have than the diameter of main cylindrical tank more the receiving means of minor diameter be inserted in the separation space to utilize the volume of having wasted.
D8 has described the method for using each receiving means transport of compressed gas that is called as shelf, described shelf support be coated with composite material pressurized container type multiple cylindrical receiving means and make them spaced apart, cylindrical receiving means longitudinally arranges to have and parallel to the axis.
Pressurized container is connected to each other and whole shelf are loaded individually, monitor and process subsequently.
In view of the foregoing, obviously, the system that is stored and transported CNG by sea route is known.Specifically, known a kind of system, described system comprises the cylindrical receiving means of pressurized container or tubing type, described receiving means is parallel and be arranged side by side in hull interior, have hull interior in order to holding cylindrical receiving means and make their isolated structures, and have connected system, described system has circuit, pressure meter and for management and control each receiving means (pipe) and the two the fill and drain valve of pressure and temperature of each receiving means (pipe) group; And cylindrical receiving means is being be formed from steel in the situation that to be the type with 1m diameter, or be made by composite material in the situation that to be the type with larger (for example,, up to 3m) diameter.Be known that equally for the particular system by means of making cylindrical metal receiving means be coated with composite material to reinforce cylindrical metal receiving means.In addition, cylindrical receiving means can be arranged in parallel, its shaft staggered volume with the space that reduces not utilize.In addition, known wherein said cylindrical receiving means through grouping to reduce the system of complexity of described connection and any monitoring.
The same known system that stores and transport non-CNG gas by sea route that following formation is provided:
-cylindrical tank, described cylindrical tank has the diameter substantially equating with the width of hull, spaced apart to ensure Security in the situation that hull damages by fluid-tight bulkhead;
-and wherein between described cylindrical tank and hull wall untapped space by thering is equal height but there is the more cylindrical tank of minor diameter and occupy.
shortcoming
That propose and become known for ship store and transport CNG solution there are some shortcomings.In all cases, the known white space not utilizing that exists in hull interior: these spaces are not by the occupied part of receiving means, thereby and therefore not for transporting gas.
Some authors (for example,, as in D2, D3 and D7) propose to arrange that the cylindrical receiving means (for example pipe or coil pipe) with staggered mutual axle is to optimize available volume.As described in other authors (as in D1) propose to increase, the diameter of receiving means to be to reduce the complexity of cost and connection, but the compatibility of the design aspect that this need to be relevant to the strength of materials.Also have other authors (as in D6) to be inserted in white space remaining between larger tank for the undersized tank of subtracting of non-pressurized gas.Also have again other authors (as in D7 and D8) to propose to reduce by cylindrical receiving means is divided into array the complexity of connection.Finally, D9 proposes to use the clad can of being made up of composite material to increase equally the intensity of pressurized container based on thickness.
In principle, be reasonably to confirm for the design of the receiving means of CNG it is that different production procedures by can be used for material therefor (, being mainly steel and composite material) regulate.In addition, their applicability is decided by the thickness of those materials, and the thickness of material depends on the condition of storage that will bear, especially pressure and temperature.To be requirement will have and the compatibility of the anchoring system of ship inside in another design constraints.For example, with regard to steel cylinder, the known receiving means generally using has about 1m to the diameter of 1.5m rice and is therefore very difficult to introduce the solution of innovating, it farthest improves the inner net volume using of ship and is favourable economically simultaneously, and meets the safety standard and the requirement that specify as the international standard such as ASME and IMO.
Also known (for example) manufactured the cylindrical steel receiving means for CNG with the above diameter of 1m and can be caused sizable design and a production difficult problem, particularly need to make to design meet restrictive international standard in the situation that specifying.
Therefore, the main target of the enterprise in described field is that (for example) reduces by means of having than the steel receiving means of traditional receiving means larger diameter the space not utilizing, but does not endanger the functional and Security of means of transportation.
The Second Problem of finding is relevant with the ability of receiving means that inspection has minor diameter.Specifically, the conventional steel cylindrical body that is called as in addition " pipe " or " bottle " with 1 rice diameter does not have the device for internal inspection, operator can not be entered inner to check container state, or to carry out the housekeeping operation of any necessity, for example regularly japanning.Conventionally to be formed by the digital scan that uses very expensive equipment and complicated software for unique diagnostic system of this receiving means type application.
In addition, these operations of great majority be in the time making ship drydocking or on land time and only removing discussed receiving means after just can carry out.
As can be seen here, considerably more advantageously, the operator of qualification can directly be carried out receiving means internal inspection aboard ship and need not make ship drydocking also need not wait for a long time dismounting and process operation.This is an aspect, and it may be by increasing the diameter of steel receiving means and for example, realizing for steel receiving means is provided for allowing the appropriate device (trap door or manhole) of inspection.
The quantity of the 3rd problem of finding and the receiving means transporting and closely related with implemented safety system.In general, pilot pressure or temperature need to and between receiving means or receiving means group with the complicated and accurate restriction of numerous circuit, manifold, sensor, valve and circuit breaker join dependency.As can be seen here, if receiving means quantity reduces, can simplify whole connected system.
With transported closely-related another problem of receiving means quantity be for example, probability of malfunction about () assembly, valve and manifold.As can be seen here, if receiving means quantity reduces, the factor of can reducing risks equally.
In view of everything, below demand be rational: the Corporate Identity in described field can overcome at least solution of the innovation of the problems referred to above.
Summary of the invention
The present invention that the present invention is intended to by defining in appended claims alleviates one or many person in above problem, the solution of problem by means of for hold and transport CNG form gas system and illustrate, described system is used (for example has different-diameter, 3m and 1.5m) the cylindrical receiving means of verifiable pressurized container type, wherein said cylindrical receiving means is combined into module and through standardization with optimize for by sea defeated.
The present invention is also provided for holding and the system of transport natural gas body and pressurized gas with ship, described system is included in the layout of the pressurized container in module, described layout comprises the pressurized container of two different sizes, one has the first diameter and another has the second less diameter, wherein said container comprises at least four larger containers in the square array that is arranged in homogeneous and the container that at least one is less, in the space that less container arrangement defines in the centre of the array of four larger containers, wherein four larger pressurized containers are furnished with public space betwixt, described space is 380mm at least, and the space between same each in smaller container and those four larger containers is 380mm at least.
These systems are preferably so that the diameter of the pressurized container of two different sizes meets following requirement:
2 ( 2 D + g ) = 2 e + 2 D + 2 g + d
2 D 2 = e + D 2
Wherein
" D " is the external diameter of four larger pressurized containers;
" d " is the external diameter of a less pressurized container;
" e " is the distance between the square nearest summit of defining at the external diameter of larger pressurized container and by four void or real edge line, and every boundary line is formed as contacting both in four larger containers; And
" g " is the minimum range between each in adjacent larger pressurized container.
Module preferably has square base (for example, each side 10m) and depends on the variable height of the cargo hold size of ship.
They can comprise fixture, circuit, valve and safety installations.
Depend on the space that will fill, they can be arranged side by side in mode repeatably.
Just there is the standard module of 10x10m substrate, likely integrate and be equipped with manhole, have 13 cylindrical pressure vessels that identical type and height still have different diameters, for example, 9 receiving means have the diameter of 3 meters, and other 4 receiving means have the diameter of 1.5 meters, are inserted in the central space space having between larger-diameter container.
In this way, likely realize for more than 73% utilization ratio of the total volume of module and compared with traditional solution extremely low receiving means sum.
All receiving means can be equipped with inspection manhole, and the operator of hull interior can directly enter manhole and not need to remove or mobile receiving means self carries out housekeeping operation and repairs liner.
Because significant creative contribution is realized various considerable advantages, the effect of these creative contributions forms direct technological progress and is not far insignificant technological progress.
Because the percentage in untapped space reduces greatly, therefore the present invention can improve the efficiency factor about the volume of the CNG that stores and transport with ship.
The present invention can provide by operator by means of trap door or manhole Direct Test and safeguard the possibility of described pressurized container.This advantage makes to test and to obtain required certification and does not need to make ship to be checked to enter dock or drydocking.
Due to extremely low receiving means quantity, therefore the present invention can simplify connection and save thus time and the cost in manufacture, installation and maintenance process.
Connect by simplification, especially, by reducing the quantity of valve and safety installations, the present invention can make accident and failure risk factor greatly reduce.
The present invention can also (for example) simplifies by means of the logic control element with special processor and software the relevant connection of any integrated management that is connected self related all parameter with such as pressure, temperature, Security and filling etc.
These and other advantage of the present invention becomes apparent the following description from the solution for preferred embodiment only described by means of accompanying drawing by example.

Embodiment
Theme of the present invention is a kind of new holding and transport system of the gas for CNG form of the cylindrical receiving means by means of verifiable pressurized container type, described cylindrical receiving means is combined into module, described module through standardization and optimize for by sea defeated.
The inside hull of the known set ship for transporting cargo has the form of essence top box, and this is mainly due to the possibility that exists horizontal waterproof bulkhead to soak and sink to prevent water.
In fact, available volume is equivalent to have substrate square or almost rectangle substantially and the parallelepiped vertically to extend through layout conventionally.
But the present invention imagines and uses the combination of verifiable cylindrical pressure vessel (100,200) with equal height different-diameter advantageously to occupy these spaces.
These cylindrical pressure vessels are combined into standardized module, there is (for example) square base, and there is the diameter between 1m and 6m, specifically, have for the diameter between 3m and the 6m of larger receiving means (100) and for the diameter between 1m and the 2.5m of the set less receiving means (200) that occupies white space.
In the hull of conventional situation, (such as but not limited to) along it, the whole length except forward andor aft has the useful inner width of about 20m to hull, and there is an internal partition at longitudinal and every in a lateral direction 10m, because it is subdivided into numerous modularization compartments, the waterproof nest chamber (40) that for example has the substrate of 10x10m and highly substantially equate with hull height, therefore can notice favourable spatial organization.
Likely use the combination of 13 verifiable cylindrical pressure vessels of vertical layout as shown in Figure 2 to 4 advantageously to occupy these compartments, each container is fixed rightly according to relevant regulations and is spaced apart.For example, preferably the distance between the container in compartment is 380mm at least, or is more preferably 600mm at least.The space that these distances also allow in the time being mounted with superheated steam container to expand, in the time loading, container volume may expand 2% or above (and also can make container change its volume in the variation of ambient temperature).
Preferably, for example, distance between the distance between wall or the border of external container and compartment or the contiguous external container (wherein not having physics wall to separate adjacent compartment) in adjacent compartments will be 600mm at least, or more preferably be 1m at least.
These spaces or space are permitted external inspection and are allowed container to expand.
In illustrated embodiment, nine containers (100) have the diameter of 3 meters and they occupy most of available volume.And having the diameter of 1.5m and they, other four containers (200) occupy the center of the white space between larger-diameter container.
Described cylindrical receiving means (100,200) is made up of traditional individual layer steel, or in alternative application, described cylindrical receiving means (100,200) has multi-layer structure, wherein have the cross section reducing a steel layer (such as but not limited to) be coated with composite consolidation material.
In one case, described nest chamber (40) can also form independently module, described module possesses suitable framework, for guaranteeing each immovability with respect to identical receiving means in cylindrical receiving means (100,200), and wherein each module can be removed with respect to the cargo hold of ship by a kind of mode, make each module self can be easy to take out instead of only from module, take out pressurized container.
In the preferred structure of a nonexcludability, the connection of described module integrated for example manifold, valve and safety system, and operatively manage in the mode of integrating by means of the logic control element with special processor and software.
Compared with the layout of the prior art of Fig. 1, the layout of this combination of Fig. 2 permits raising the efficiency factor.
In the arrangement illustrated of Fig. 2, as further described, aspect the volume utilizing for transporting CNG, obtaining 73.87% efficiency factor above.This with as in Fig. 1, arrange with identical compartment and 54.36% factor of the isolated cylindrical traditional arrangement with 1 rice diameter only forms contrast.
Specifically, 64 receiving means are installed in traditional solution, and in the solution (, using two kinds of different-diameters of 3m and 1.5m) of combination of the present invention, 13 receiving means have only been installed.
Use simple math equation group can obtain desirable combination and arrange, described math equation group consider two types pressurized container different radii value (variable to adapt to free space) and between described two types of pressurized containers fixing space in accordance with regulations conventionally.
As shown in FIG. 5, also may have other to arrange, wherein Fig. 5 is base configuration, and it only has single small container and four bulk containers, and this layout can be expanded in due course, has other small container and have bulk container in space in continuous array.
Fig. 5 is shown in the relative dimensions that will consider while carrying out mathematical computations.
" D " is the external diameter of larger pressurized container.
" d " is the external diameter of less pressurized container.
" e " is the distance between described external diameter and square nearest summit.
" g " is the minimum range between two pressurized containers.
" L " is free space, and container need to be engaged in this space.
Determine that two equations that calculate are:
2 ( 2 D + g ) = 2 e + 2 D + 2 g + d
2 D 2 = e + D 2
Wherein " g " normally fixed value, for example, ABS rule is illustrated in the minimum range of the 0.380m between the outer surface of two different pressurized containers.
Use this set of equation, likely in the time of the external diameter value of a selected pressurized container (for bulk container or small container), determine another value.
In the time possessing major diameter, (be for example greater than 1m, for example 3m and 1.5m), receiving means has it can be carried out by personnel internal inspection advantage by means of such as manhole, flanged trap door etc., wherein manhole its diameter in the situation that being circular can be measured as at least 18 or 24 inches, or is being in difform situation, to have same homalographic.Manhole can be arranged in each top of described cylindrical receiving means, and operator can be easy to come in and go out manhole to check the preservation state of internal surface of its container whereby, and inner surface of container mainly may being corroded property destroyed.In addition, manhole is permitted personnel and is carried out where necessary housekeeping operation, for example, carries out interior lacquering and repair, and for testing by means of nondestructive testing (NDT) and checking the operation of the structural robustness of receiving means, and general inside lining work.
These receiving means are also shown as the opening that is positioned possess for its bottom.This substrate opening can have the diameter of (for example) 12 inches, and it can be alternatively for filling and discharge the fluid of the liquid that comprises any condensation, and the discharge of described fluid is to facilitate by gravity.
Each pressurized container and set for loading and the pipe-line system interconnection of unloading operation, described pipe-line system (for example,, by being preferably the opening of 12 inches (30cm)) for example, arrives main collector from the bottom (passing through mortor operated valve) of each container.Fig. 6 and Fig. 7 illustrate this type of connection in a schematic way.
Main collector can comprise various pressure rating, and for example three (high pressure-for example 250 bar, middle pressure-for example 150 Palestine and Israels and low pressure-for example 90 bar) wherein add a blowing collector and a nitrogen collector for inertia object.
The combination side by side with the container of different-diameter is modular and is easy to be multiplied, such as but not limited to, there is the situation of the module with 10 × 10m substrate of hull interior of about 30m available width.It is also very flexible, because it combines different diameters in mode favourable on volume all the time.
The cylindrical receiving means of describing in this way can meet the effective standard of management for the receiving means of the gas transport such as such as compressed natural gas or other gas in high pressure lower compression.Those standards can be including (for example) ASME or API and the industrial standard being associated.
The complexity of managing heavy specification in the time that processing has large diameter high pressure steel receiving means has obtained abundant compensation by a large amount of advantages of having described.
The structure with each fluid-tight module also makes to use suitable gas (for example, nitrogen) to produce and maintain inert atmosphere, and this will prevent contingent explosive mixing the rock gas accidental release in the situation that.This gas can (for example) surround container in compartment.Alternately, engine exhaust is because its composition is rich in CO 2and can be for this kind of inerting function.
Compared with horizontal installation, the vertical layout of cylindrical receiving means is permitted the dynamic load in response to ship in navigation process better.In addition, vertically arrange and allow more easily to change where necessary the single container in module or compartment 40, they can be raised out, and do not need first to remove from above other container, unless that compartment is stacked on is over each other.
In some constructions, at least some (or at all containers of specifying in compartment) in container or container can be set to be longer than depth of hull, so that the row that make odd number extend to the top (see Fig. 6, be positioned at the position of profile top) of container arrangement above from the substrate of hull just.Stacking owing to not existing, therefore this structure can also be realized the quick mounting time potentially.
Container 10 (Fig. 6) is installed in vertical position and is also allowed the liquid of condensation to drop to bottom in the impact of gravity, before CNG unloading, can for example, unload thus the liquid of condensation by () at the opening 7 of 12 inches of each container 10 bottoms from container.After all, will be favourable equally from the bottom discharge gas of container 10.
At most of pipelines 60, in the situation that module bottom is installed, the center of gravity of whole layout also will be at lower, and this is at sea or improve in gas transport process that stability is particularly recommended or preferably.
By farthest increasing the size of indivedual larger containers, for example nearly nearly 30 meters of 6 meters and length of the diameter (for example) by making them, for held identical total volume, can reduce the sum of container, this allows to reduce the complexity of connection and pipeline enclosure then, and therefore reduce and for example conventionally appear at, compared with the quantity of the possible leakage point in weak position (, weld, junction point and manifold).Preferred layout needs at least diameter of 2m.
The concept that use is identical with the interconnection of the loading or unloading of the gas for stored, can reserve a special container for liquid storage (as condensed fluid) in the one in each compartment or multiple chamber.Therefore, compartment may all link together, and to allow this class I liquid I to be distributed to special container (or compartment) from other compartment, the feature of ship is to have multiple compartments conventionally.For realizing this object, likely arrange that valve and fluid flow management system to allow any condensed fluid to redistribute, for example, are distributed in less container in container, that is, and be collected in the bottom of container in transportation process at it after.Less container conventionally will be enough greatly to collect liquid component (impurity of normally finding) in rock gas, collects liquid component by the larger reservoir volume that damages CNG and can use and change in a larger container.
The manifold that input and output gas reservoir conduit can advantageously connect by valve is connected with at least one in metering, heating and/or purging system and cleaning system.They can preferably pass through distributed control system (DCS) remote activation.
Pipe diameter is preferably as follows:
18 inches.For being exclusively used in three main collectors (low pressure, pressure and high pressure) of CNG load/unload.
24 inches.Be used for blowing down CNG pipeline.
6 inches.For the pipe of the inert gas of feeding to module.
10 inches.Be used for blowing down inert gas piping.
10 inches.For being exclusively used in the pipe of possible liquid containing/unloading.
Predict as international code, standard and rule, all modules are preferably equipped with enough suppression systems.
In another preferred solution, described system can also be applied to transport other gaseous hydrocarbon except CNG, or other gas, for example nitrogen, oxygen, carbon dioxide and hydrogen.But preferred purposes is CNG transport.
CNG can comprise the multiple potential constituent element with variable ratio of mixture, and some are the mixing that gas phase and other are liquid phase or gas phase and liquid phase.Those constituent elements generally include one or many person in following compound: C 2h 6, C 3h 8, C 4h 10, C 5h 12, C 6h 14, C 7h 16, C8H18, C9+ hydro carbons, CO 2and H 2s, may add liquid toluene, diesel oil and octane.
Pressurized container as herein described can deliver multiple gases, for example, the direct original gas from drilling well, including (for example) when when compression original rock gas-original CNG or RCNG or H2 or CO2 or the rock gas (methane) of processing or (for example) have CO2 share up to 14% mole, up to the original of the H2S share of 1,000ppm or H2 and CO2 gaseous impurity or other impurity or corrosive material or rock gas that section processes is crossed.But preferred purposes is CNG transport, described CNG is CNG or the treated pure CNG that reaches the standard that can be delivered to terminal use's (for example, business, industry or house) that original CNG, section processes are crossed.
CNG can comprise the various potential constituent element with variable ratio of mixture, and some are the mixing that gas phase and other are liquid phase or gas phase and liquid phase.Those constituent elements generally include one or many person in following compound: C2H6, C3H8, C4H10, C5H12, C6H14, C7H16, C8H18, C9+ hydro carbons, CO2 and H2S, may add liquid toluene, diesel oil and octane and other impurity/materials.
Transport CNG conventionally in exceed 60 bar and may exceed 100 bar, 150 bar, 200 bar or 250 bar and may reach 300 bar or the pressure of the peak value of 350 bar under.
Layout below receiving means of fluid filling and discharge system (and interconnection) between the valve system being associated and cylindrical receiving means and between module contributes to the stability of navigation and has reduced the height of center of gravity.
