Petroleum and Its Modern Uses[1] Petroleum, coal, and natural gas are the most widely used sources of energy in the m odern world. They are of primary importance in the industrialized countries, where vast am ounts of energy are consumed to operate the different kinds of machines used today. The se three energy sources are collectively referred to as fossil fuels.石油、煤炭和天然气是现代世界最广泛使用的能源。
它们在工业化国家中最为重要,在这些国家,人们消耗大量的能源来操作今天使用的各种机器。
这三种能源统称为化石燃料。
[2] At various depths beneath land and sea, there are accumulations of hydrocarbons form ed millions and even hundreds of millions of years ago by decomposition of animal and v egetable remains. They were covered by sand or mud, which in time was itself covered by the water of the seas. Hydrocarbons are compounds of hydrogen and carbon which, at n ormal temperatures and pressures, may be gaseous, liquid or solid according to their mole cular complexity. The natural deposits are correspondingly gaseous, liquid or solid, dependi ng on the relative proportion of the various hydrocarbons present in mixture. Petroleum is composed largely of the remains of these tiny marine animals and plants that lived so lo ng ago.在陆地和海洋的不同深处,有数百万年甚至数亿年前由于动物和植物残骸的分解而形成的碳氢化合物的积聚。

The complex nature of wellstreams is responsible for the complex processing of the produced fluids (gas, oil ,water,and solids).The hydrocarbon portion must be separated into products that can be stored and/or transported.The nonhydrocarbon contaminants must be removed as much as feasible to meet storage, transport, reinjection, and disposal specifications. Ultimate disposal of the various waste streams depends on factors such as the location of the field and the applicable environmental regulations. The overriding criterion for product selection, construction, and operation decisions is economics.油气井井流的复杂性质,决定了所产流体(气、油、水和固体)的加工十分复杂。
必须分出井流中的烃类,使之成为能储存和/或能输送的各种产品;必须尽可能地脱除井流中的非烃杂质,以满足储存、输送、回注和排放的规范。
各类废弃物的最终处置取决于各种因素,如油气田所处地域和所采用的环保规定等。
经济性是决定油气田产品设计、建筑和操作决策的最重要准则。

( 1of6 )United States Patent Application20050205157 Kind Code A1 Hutchinson, Ray J. September 22, 2005Service station leak detection and recovery systemAbstractA fueling environment that distributes fuel from a fuel supply to fuel dispensers in a daisy chain arrangement with a double walled piping system. Fuel leaks that occur within the double walled piping system are returned to the underground storage tank by the outer wall of the double walled piping. This preserves the fuel for later use and helps reduce the risk of environmental contamination. Leak detectors may also be positioned in fuel dispensers detect leaks and provide alarms for the operator and help pinpoint leak detection that has occurred in the piping system proximate to a particular fuel dispenser or in between two consecutive fuel dispensers.Inventors:Hutchinson, Ray J.; (Houma, LA)Correspondence Name and Address: WITHROW & TERRANOVA, P.L.L.C.

Initially, the regulations required double walled tanks for storing fuel accompanied by leak detection for the tanks. Subsequently, the regulatory agencies have become concerned with the piping between the underground storage tank and the fuel dispensers and are requiring double walled piping throughout the fueling environment as well.[0003] Typically, the double walled piping that extends between fuel handling elements within thefueling environment terminates at each end with a sump that is open to the atmosphere. In the event of a leak, the outer pipe fills and spills into the sump. The sump likewise catches other debris, such as water and contaminants that contaminate the fuel caught by the sump, thereby making this contaminated fuel unusable. Thus, the sump is isolated from the underground storage tank, and fuel captured by the sump is effectively lost.[0004] Coupled with the regulatory changes in the requirements for the fluid containment vessels are requirements for leak monitoring such that the chances of fuel escaping to the environment are minimized. Typical leak detection devices are positioned in the sumps. These leak detection devices may be probes or the like and may be connected to a control system for the fueling environment such that the fuel dispensing is shut down when a leak is detected.[0005] Until now, fueling environments have been equipped with elements from a myriad of suppliers. Fuel dispensers might be supplied by one company, the underground storage tanks by a second company, the fuel supply piping by a third company, and the tank monitoring equipment by yet a fourth company. This makes the job of the designer and installer of the fueling environment harder as compatibility issues and the like come into play. Further, it is difficult for one company to require a specific leak detection program with its products. Interoperability of components in a fueling environment may provide economic synergies to the company able to effectuate such, and provide better, more integrated leak detection opportunities.[0006] Any fuel piping system that is installed for use in a fueling environment should advantageously reduce the risk of environmental contamination when a leak occurs and attempt to recapture fuel that leaks for reuse and to reduce excavation costs, further reducing the likelihood of environmental contamination. Still further, such a system should include redundancy features and help reduce the costs of clean up.SUMMARY OF THE INVENTION[0007] The present invention capitalizes on the synergies created between the tank monitoring equipment, the submersible turbine pump (STP), and the fuel dispenser in a fueling environment.A fluid connection that carries a fuel supply for eventual delivery to a vehicle is made between the underground storage tank and the fuel dispensers via double walled piping. Rather than use the conventional sumps and low point drains, the present invention drains any fuel that has leaked from the main conduit of the double walled piping back to the underground storage tank. This addresses the need to recapture the fuel for reuse and to reduce fuel that is stored in sumps which must later be retrieved and excavated by costly service personnel.[0008] The fluid in the outer conduit may drain to the underground storage tank by gravity coupled with the appropriately sloping piping arrangements, or a vacuum may be applied to the outer conduit from the vacuum in the underground storage tank. The vacuum will drain the outer conduit. Further, the return path may be fluidly isolated from the sumps, thus protecting the fuel from contamination.[0009] In an exemplary embodiment, the fuel dispensers are connected to one another via a daisy chain fuel piping arrangement rather than by a known main and branch conduit arrangement. Fuel supplied to a first fuel dispenser by the STP and conduit is carried forward to other fuel dispensers coupled to the first fuel dispenser via the daisy chain fuel piping arrangement. The daisy chain is achieved by a T-intersection contained within a manifold in each fuel dispenser. Fuel leaking in the double walled piping is returned through the piping network through each downstream fuel dispenser before being returned to the underground storage tank.[0010] The daisy chain arrangement allows for leak detection probes to be placed within each fuel dispenser so that leaks between the fuel dispensers may be detected. The multiplicity of probes causes leak detection redundancy and helps pinpoint where the leak is occurring. Further, the multiple probes help detect fuel leaks in the outer conduit of the double walled piping. This is accomplished by verifying that fuel dispensers downstream of a detected leak also detect a leak. If they do not, a sensor has failed or the outer conduit has failed. A failure in the outer piping is cause for serious concern as fuel may be escaping to the environment and a corresponding alarm may be generated.[0011] Another possibility with the present invention is to isolate sumps, if still present within the fuel dispenser, from this return path of captured leaking fuel such that contaminants are precluded from entering the leaked fuel before being returned to the underground storage tank. In this manner, fuel may potentially be reused since it is not contaminated by other contaminants, such as water, and reclamation efforts are easier. Since the fuel is returned to the underground storage tank, there is less danger that a sump overflows and allows the fuel to escape into the environment.[0012] Those skilled in the art will appreciate the scope of the present invention and realize additional aspects thereof after reading the following detailed description of the preferred embodiments in association with the accompanying drawing figures.BRIEF DESCRIPTION OF THE DRAWING FIGURES[0013] The accompanying drawing figures incorporated in and forming a part of this specification illustrate several aspects of the invention, and together with the description serve to explain the principles of the invention.[0014] FIG. 1 illustrates a conventional communication system within a fueling environment in the prior art;[0015] FIG. 2 illustrates a conventional fueling path layout in a fueling environment in the prior art;[0016] FIG. 3 illustrates, according to an exemplary embodiment of the present invention, a daisy chain configuration for a fueling path in a fueling environment;[0017] FIG. 4 illustrates, according to an exemplary embodiment of the present invention, a fueldispenser;[0018] FIG. 5 illustrates a first embodiment of a fuel return to underground storage tank arrangement;[0019] FIG. 6 illustrates a second embodiment of a fuel return to underground storage tank arrangement; and[0020] FIG. 7 illustrates a flow chart showing the leak detection functionality of the present invention.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS[0021] The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the invention and illustrate the best mode of practicing the invention. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the invention and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.[0022] Fueling environments come in many different designs. Before describing the particular aspects of the present invention (which begins at the description of FIG. 3), a brief description of a fueling environment follows. A conventional exemplary fueling environment 10 is illustrated in FIGS. 1 and 2. Such a fueling environment 10 may comprise a central building 12, a car wash 14, and a plurality of fueling islands 16.[0023] The central building 12 need not be centrally located within the fueling environment 10, but rather is the focus of the fueling environment 10, and may house a convenience store 18 and/ora quick serve restaurant 20 therein. Both the convenience store 18 and the quick serve restaurant20 may include a point of sale 22, 24, respectively. The central building 12 may further house a site controller (SC) 26, which in an exemplary embodiment may be the G-SITE.RTM. sold by Gilbarco Inc. of Greensboro, N.C. The site controller 26 may control the authorization of fueling transactions and other conventional activities as is well understood. The site controller 26 may be incorporated into a point of sale, such as point of sale 22 if needed or desired. Further, the site controller 26 may have an off-site communication link 28 allowing communication with a remote location for credit/debit card authorization, content provision, reporting purposes or the like, as needed or desired. The off-site communication link 28 may be routed through the Public Switched Telephone Network (PSTN), the Internet, both, or the like, as needed or desired.[0024] The car wash 14 may have a point of sale 30 associated therewith that communicates with the site controller 26 for inventory and/or sales purposes. The car wash 14 alternatively may be a stand alone unit. Note that the car wash 14, the convenience store 18, and the quick serve restaurant 18 are all optional and need not be present in a given fueling environment.[0025] The fueling islands 16 may have one or more fuel dispensers 32 positioned thereon. The fuel dispensers 32 may be, for example, the ECLIPSE.RTM. or ENCORE.RTM. sold by Gilbarco Inc. of Greensboro, N.C. The fuel dispensers 32 are in electronic communication with the site controller 26 through a LAN or the like.[0026] The fueling environment 10 also has one or more underground storage tanks 34 adapted to hold fuel therein. As such the underground storage tank 34 may be a double walled tank. Further, each underground storage tank 34 may include a tank monitor (TM) 36 associated therewith. The tank monitors 36 may communicate with the fuel dispensers 32 (either through the site controller 26 or directly, as needed or desired) to determine amounts of fuel dispensed and compare fuel dispensed to current levels of fuel within the underground storage tanks 34 to determine if the underground storage tanks 34 are leaking.[0027] The tank monitor 36 may communicate with the site controller 26 and further may have an off-site communication link 38 for leak detection reporting, inventory reporting, or the like. Much like the off-site communication link 28, off-site communication link 38 may be through the PSTN, the Internet, both, or the like. If the off-site communication link 28 is present, the off-site communication link 38 need not be present and vice versa, although both links may be present if needed or desired. As used herein, the tank monitor 36 and the site controller 26 are site communicators to the extent that they allow off site communication and report site data to a remote location.[0028] For further information on how elements of a fueling environment 10 may interact, reference is made to U.S. Pat. No. 5,956,259, which is hereby incorporated by reference in its entirety. Information about fuel dispensers may be found in commonly owned U.S. Pat. Nos. 5,734,851 and 6,052,629, which are hereby incorporated by reference in their entirety. Information about car washes may be found in commonly owned U.S. patent application Ser. No. 10/______ filed 6 May 2002, entitled IMPROVED SERVICE STA TION CAR W ASH, which is hereby incorporated by reference in its entirety. An exemplary tank monitor 36 is the TLS-350R manufactured and sold by Veeder-Root. For more information about tank monitors 36 and their operation, reference is made to U.S. Pat. Nos. 5,423,457; 5,400,253; 5,319,545; and 4,977,528, which are hereby incorporated by reference in their entireties.[0029] In addition to the various conventional communication links between the elements of the fueling environment 10, there are conventional fluid connections to distribute fuel about the fueling environment as illustrated in FIG. 2. Underground storage tanks 34 may each be associated with a vent 40 that allows over-pressurized tanks to relieve pressure thereby. A pressure valve (not shown) is placed on the outlet side of each vent 40 to open to atmosphere when the underground storage tank 34 reaches a predetermined pressure threshold. Additionally, under-pressurized tanks may draw air in through the vents 40. In an exemplary embodiment, two underground storage tanks 34 exist--one a low octane tank (87) and one a high octane tank (93). Blending may be performed within the fuel dispensers 32 as is well understood to achieve an intermediate grade of fuel. Alternatively, additional underground storage tanks 34 may be provided for diesel and/or an intermediate grade of fuel (not shown).[0030] Pipes 42 connect the underground storage tanks 34 to the fuel dispensers 32. Pipes 42 may be arranged in a main conduit 44 and branch conduit 46 configuration, where the main conduit 44 carries the fuel to the branch conduits 46, and the branch conduits 46 connect to the fuel dispensers 32. Typically, pipes 42 are double walled pipes comprising an inner conduit and an outer conduit. Fuel flows in the inner conduit to the fuel dispensers, and the outer conduit insulates the environment from leaks in the inner conduit. For a better explanation of such pipes and concerns about how they are connected, reference is made to Chapter B13 of PIPING HANDBOOK, 7.sup.th edition, copyright 2000, published by McGraw-Hill, which is hereby incorporated by reference.[0031] In a typical service station installation, leak detection may be performed by a variety of techniques, including probes and leak detection cables. More information about such devices can be found in the previously incorporated PIPING HANDBOOK. Conventional installations do not return to the underground storage tank 34 fuel that leaks from the inner conduit to the outer conduit, but rather allow the fuel to be captured in low point sumps, trenches, or the like, where the fuel mixes with contaminants such as dirt, water and the like, thereby ruining the fuel for future use without processing.[0032] While not shown, vapor recovery systems may also be integrated into the fueling environment 10 with vapor recovered from fueling operations being returned to the underground storage tanks 34 via separate vapor recovery lines (not shown). For more information on vapor recovery systems, the interested reader is directed to U.S. Pat. Nos. 5,040,577; 6,170,539; and Re. 35,238, and U.S. patent application Ser. No. 09/783,178 filed 14 Feb. 2001, all of which are hereby incorporated by reference in their entireties.[0033] Now turning to the present invention, the main and branch supply conduit arrangement of FIG. 2 is replaced by a daisy chain fuel supply arrangement as illustrated in FIG. 3. The underground storage tank 34 provides a fuel delivery path to a first fuel dispenser 32, via a double walled pipe 48. The first fuel dispenser 32, is configured to allow the fuel delivery path to continue onto a second fuel dispenser 32.sub.2 via a daisy chaining double walled pipe 50. The process repeats until an nth fuel dispenser 32.sub.n is reached. Each fuel dispenser 32 has a manifold 52 with an inlet aperture and an outlet aperture as will be better explained below. In the nth fuel dispenser 32.sub.n, the outlet aperture is terminated conventionally as described in the previously incorporated PIPING HANDBOOK.[0034] As better illustrated in FIG. 4, each fuel dispenser 32 comprises a manifold 52 with a T-intersection housed therein. The T-intersection 54 allows the fuel line conduit 56 to be stubbed out of the daisy chaining double walled pipe 50 and particularly to extend through the outer wall 58 of the daisy chaining double walled pipe 50. This T-intersection 54 may be a conventional T-intersection such as is found in the previously incorporated PIPING HANDBOOK. The manifold 52 comprises the aforementioned inlt aperture 60 and outlet aperture 62. While shown on the sides of the manifold 52's housing, they could equivalently be on the bottom side of the manifold 52, if desired. Please note that the present invention is not limited to a manifold 52 witha T-joint, and that any other suitable configuration may be used that allows fuel to be supplied to a fuel dispenser 32 and allows to continue on as well to the next fuel dispenser 32 until the last fuel dispenser 32 is reached.[0035] A leak detection probe 64 may also be positioned within the manifold 52. This leak detection probe 64 may be any appropriate liquid detection sensor as needed or desired. The fuel dispenser 32 has conventional fuel handling components 66 therein, such as fuel pump 68, a vapor recovery system 70, a fueling hose 72, a blender 74, a flow meter 76, and a fueling nozzle 78. Other fuel handling components 66 may also be present as is well understood in the art.[0036] With this arrangement, the fuel may flow into the fuel dispenser 32 in the fuel line conduit 56, passing through the inlet aperture 60 of the manifold 52. A check valve 80 may be used if needed or desired as is well understood to prevent fuel from flowing backwards. The fuel handling components 66 draw fuel through the check valve 80 and into the handling area of the fuel dispenser 32. Fuel that is not needed for that fuel dispenser 32 is passed through the manifold 52 upstream to the other fuel dispensers 32 within the daisy chain. A sump (not shown) may still be associated with the fuel dispenser 32, but it is fluidly isolated from the daisy chaining double walled pipe 50.[0037] A first embodiment of the connection of the daisy chaining double walled pipe 50 to the underground storage tank 34 is illustrated in FIG. 5. The daisy chaining double walled pipe 50 connects to a casing construction 82, which in turn connects to the double walled pipe 48. A submersible turbine pump 84 is positioned within the underground storage tank 34, preferably below the level of the fuel 86 within the underground storage tank 34. For a more complete exploration of the casing construction 82 and the submersible turbine pump 84, reference is made to U.S. Pat. No. 6,223,765 assigned to Marley Pump Company, which is incorporated herein by reference in its entirety and the product exemplifying the teachings of the patent explained in Quantum Submersible Pump Manual: Installation and Operation, also produced by the Marley Pump Company, also incorporated by reference in its entirety. In this embodiment, fuel captured by the outer wall 58 is returned to the casing construction 82 such as through a vacuum or by gravity feeds. A valve (not shown) may allow the fuel to pass into the casing construction 82 and thereby be connected to the double walled pipe 48 for return to the underground storage tank 34. The structure of the casing construction in the '765 patent is well suited for this purpose having multiple paths by which fuel may be returned to the outer wall of the double walled pipe that connects the casing construction 82 to the submersible turbine pump 84.[0038] A second embodiment of the connection of the daisy chaining double walled pipe 50 to the underground storage tank 34 is illustrated in FIG. 6. The casing construction 82 is substantially identical to the previously incorporated U.S. Pat. No. 6,223,765. The daisy chaining double walled pipe 50 however comprises a fluid connection 88 to the double walled pipe 48. This allows the fuel in the outer wall 58 to drain directly to the underground storage tank 34, instead of having to provide a return path through the casing construction 82. Further, the continuous fluid connection from the underground storage tank 34 to the outer wall 58 causes any vacuum present in the underground storage tank 34 to also be existent in the outer wall 58 of the daisy chaining doublewalled pipe 50. This vacuum may help drain the fuel back to the underground storage tank 34. In an exemplary embodiment, the fluid connection 88 may also be double walled so as to comply with any appropriate regulations.[0039] FIG. 7 illustrates the methodology of the present invention. During new construction of the fueling environment 10, or perhaps when adding the present invention to an existing fueling environment 10, the daisy chained piping system according to the present invention is installed (block 100). The pipe connection between the first fuel dispenser 32.sub.1 and the underground storage tank 34 may, in an exemplary embodiment, be sloped such that gravity assists the drainage from the fuel dispenser 32 to the underground storage tank 34. The leak detection system, and particularly, the leak detection probes 64, are installed in the manifolds 52 of the fuel dispensers 32 (block 102). Note that the leak detection probes 64 may be installed during construction of the fuel dispensers 32 or retrofit as needed. In any event, the leak detection probes 64 may communicate with the site communicators such as the site controller 26 or the tank monitor 36 as needed or desired. This communication may be for alarm purposes, calibration purposes, testing purposes or the like as needed or desired. Additionally, this communication may pass through the site communicator to a remote location if needed. Further, note that additional leak detectors (not shown) may be installed for redundancies and/or positioned in the sumps of the fuel dispensers 32. Still further, leak detection programs may be existent to determine if the underground storage tank 34 is leaking. These additional leak detection devices may likewise communicate with the site communicator as needed or desired.[0040] The fueling environment 10 operates as is conventional, with fuel being dispensed to vehicles, vapor recovered, consumers interacting with the points of sale, and the operator generating revenue (block 104). At some point a leak occurs between two fuel dispensers 32.sub.x and 32.sub.x+1. Alternatively, the leak may occur at a fuel dispenser 32.sub.x+1 (block 106). The leaking fuel flows towards the underground storage tank 34 (block 108), as a function of the vacuum existent in the outer wall 58, via gravity or the like. The leak is detected at the first downstream leak detection probe 64 (block 110). Thus, in the two examples, the leak would be detected by the leak detection probe 64 positioned within the fuel dispenser 32.sub.x. This helps in pinpointing the leak. An alarm may be generated (block 112). This alarm may be reported to the site controller 26, the tank monitor 36 or other location as needed or desired.[0041] A second leak detection probe 64, positioned downstream of the first leak detection probe 64 in the fuel dispenser 32.sub.x-1, will then detect the leaking fuel as it flows past the second leak detection probe 64 (block 114). This continues, with the leak detection probe 64 in each fuel dispenser 32 downstream of the leak detecting the leak until fuel dispenser 32.sub.1 detects the leak. The fuel is then returned to the underground storage tank 34 (block 116).[0042] If all downstream leak detection probes 64 detect the leak at query block 118, that is indicative that the system works (block 120). If a downstream leak detection probe 64 fails to detect the leak during the query of block 118, then there is potentially a failure in the outer wall 58 and an alarm may be generated (block 122). Further, if the leak detection probes 64 associated with fuel dispensers 32.sub.x+1 and 32.sub.x-1 both detect the leak, but the leak detection probe。

The hydrocarbon portion must be separated into products that can be stored and/or transported. The nonhydrocarbon contaminants must be removed as much as feasible to meet storage, transport, reinjection, and disposal specifications. Ultimate disposal of the various waste streams depends on factors such as the location of the field and the applicable environmental regulations.

因此,从运输到工艺设备的接触器并进入输送管道间TEG的损失是必不可少的,并且应该作为产品监测项目中评估气体组分的一部分。
本文详细介绍了挪威国家石油公司为了评估含水量如何进行管道(运输网)的运行实践产品监测评估,TEG和富气中的其他成分可能会影响运输管道里流体的流动性以及对腐蚀的评估。
一个关于TEG-水评估的例子里详细描述了管道里的液体滞留和腐蚀评估。
TEG携带的测量和量化在正常操作期间将贫TEG送入甘醇吸收塔的顶部,以便从天然气中除去过量的水和达到给定的水露点。

可能还有还有少量的贫甘醇溶液液滴经过气体洗涤器变为饱和气,但这种影响在此项工艺中是可以忽略不计的。
水露点(WDP)和饱和天然气气体成分在气体从所有输送支线输送到运输干线时计量。
在任何摄氏度或高精度下不同的平台/设备有不同的仪器进行分析和测量,所有的数据都可以在控制室里通过网上产品的监测和工作人员的检查得到。
甘醇溶液引起的水露点数据可使用图6.1参考计算,该水露点数据是摄氏度可以转换为ppm或摩尔%表示[4]。
水,甘醇溶液和其他天然气组分之间有着复杂的相互作用。
比如C1和C2在决定管道中液体凝结(液体滴出)的条件中起着重要的作用。
由于这种复杂的相互作用,三次加协会(CPA),即“工具”通过一整篇文章,并且建立两种模型均应用Calsep软件来预测管道里液体滴出的条件。

TEG的马赛-科普曼(MC)参数必须被调整好。
TEG(选择PV AP模型= M &C)的Soave-Redlich-Kwong/Mathias-Copeman(SRK-MC)应根据以下调整参数来选择:MC1-C1= 2.83, MC2-C2 = -4.128, MC3-C3 = 2.766.TEG饱和度的计算是基于乙二醇接触器下游的洗涤条件,如表1。

通过变化参数使用模型1和模型2模拟和工具A的计算相图如图1所示。
图1 2002年在不同的参数下使用相图模拟和软件平台测试的TEG实相图稳态流动数值模拟基于上一节中的主要结论,模型1和模型2可以选择,以执行一个使用OLGA(1)6.2版(稳态模拟)液体滞留评价。
输入到模型的数据是基于各年计算在指定期间内每年平均气体的组成和条件(基于每小时的测量)。
然而只有模型2在本文中被突出显示,如在图1中可以看出。
模型2给出了在较高的临界压力和温度下由于参数TEG-C1和TEG-C2的变动比其他模型更宽的相图。
这导致在正常和异常操作条件下可能的润湿。
换言之,模型2会给最坏的情况下的液体滞留量并且计算出腐蚀速率。
一个复杂的管道系统可以使用稳态仿真来创建,每个分支的所有数据输入可以根据产品的监测来确定。
全气体成分+ TEG的主要输入结转可根据模型1和模型2的结果来插入。
在主要运输线,一个基于重量分数的特定组合条件可以被应用,这种混合计算可能在气体的成分/ TEG分析来进行。
一个稳态模拟布局的例子示于图2。
FC:饱和气体成分图2 插图的管道系统与基于重量分数的气体成分分布的稳态流动模型从案例研究1的混合组合物的最终结果列于表2中。
这些结果代表所有气体组合物进入管道系统的结构和使用模型2的计算方法。
表2 作为与模型2稳态流动模拟在最后一节中的混合气体的成分*使用模型2计算饱和状态模拟输出可以在早期沉淀积聚和出口之间被集中的区域。
某些信息可以取自模拟,即KP其中第一滴液体冷凝,最大液体滞留量(以总体积和其分数),压力和温度分布,流体规律和燃气流量曲线。
稳态仿真结果的样本案例如下一页的图3。
液体沉淀在指定时间内是可以预测的,如表3所示。
液体(含水-TEG)保持了预期滞留在一个较长的时期。
可以从稳态模拟得到在稳定状态条件下的总积累液体,但水的流速和所计算的累计液可以使用流体分析软件(用于TEG计算是相同的)来预测。
可以预测达到稳态条件所需的时间。
总结使用的所有时期也许可以计算出来共有235立方米液体(含水TEG )可能积聚在管道内。
这一数额的计算是基于正常和异常时期情况下的。
模型2表明,液体(含水TEG )滞留可能从2005年及以后发生的。

图3 一个分支出口使用模型2输入的稳态流模拟示例预测腐蚀速率与腐蚀产物当H 2S 和CO 2同时存在时,腐蚀将受主要气体的控制,这主要取决于出口气体中两种组分分压之间的关系[7]。
图4给出了一个根据二氧化碳分压/部分硫化氢的压力(PCO2/ PH2S)比的预期腐蚀机理。
图4 CO2-H2S腐蚀的机理在挪威大陆架运送的大部分气体中脱硫CO2气体PCO2/ PH2S > > 500中的比率,在这项研究中H2S含量大多低于NACE MR0175 / ISO 15156.8。
因此,H2S 对全面腐蚀的影响可以忽略。
如前所述,TEG的浓度取决于洗涤器下游乙二醇接触器的温度和压力。
TEG 浓度随压力和温度的增加而增加。
当气体进入提升管和管道后气体的温度和压力降低到一定的条件下,TEG 会凝结并在管道内壁形成TEG的液体膜和水。
乙二醇具有吸湿性,将从气体中提取水使从气体达到平衡状态,即使在气体中的含水量符合规定。
在理论上乙二醇和水的混合物会导致一定的腐蚀[3]。
在这项研究中,预测的金属损耗是从一个全面腐蚀点开始,其中,当暴露于腐蚀性流体下所述管道所有内壁以同样的速度被腐蚀。
腐蚀速率的预测是通过预测可能的液滴的稳定状态模拟启动。
流体分析软件是用来预测的液滴的稳态仿真预测位置的TEG浓度。
