摘要： A natural gas liquefying apparatus includes: a precooling unit, which is a treatment unit configured to precool natural gas; a liquefying unit, which is a treatment unit configured to liquefy the natural gas; a refrigerant cooling unit, which is a treatment unit configured to cool a liquefying refrigerant; a compression unit configured to compress vaporized refrigerants; and a pipe rack including air-cooled coolers arrayed and arranged on an upper surface. The treatment units and the compression unit are separately arranged in a first arrangement region and a second arrangement region arranged opposed to each other across a long side of the pipe rack. The pipe rack interposed between the first and second arrangement regions has a region in which no air-cooled cooler is arranged in order to arrange a plurality of pipes, through which refrigerants are allowed to flow, in a direction of a short side of the pipe rack.

摘要： A system and method for cooling and liquefying a gas in a heat exchanger that includes compressing and cooling a mixed refrigerant using first and last compression and cooling cycles so that high pressure liquid and vapor streams are formed. The high pressure liquid and vapor streams are cooled in the heat exchanger and then expanded so that a primary refrigeration stream is provided in the heat exchanger. The mixed refrigerant is cooled and equilibrated between the first and last compression and cooling cycles so that a pre-cool liquid stream is formed and subcooled in the heat exchanger. The stream is then expanded and passed through the heat exchanger as a pre-cool refrigeration stream. A stream of gas is passed through the heat exchanger in countercurrent heat exchange with the primary refrigeration stream and the pre-cool refrigeration stream so that the gas is cooled. A resulting vapor stream from the primary refrigeration stream passage and a two-phase stream from the pre-cool refrigeration stream passage exit the warm end of the exchanger and are combined and undergo a simultaneous heat and mass transfer operation prior to the first compression and cooling cycle so that a reduced temperature vapor stream is provided to the first stage compressor so as to lower power consumption by the system. Additionally, the warm end of the cooling curve is nearly closed further reducing power consumption. Heavy components of the refrigerant are also kept out of the cold end of the process, reducing the possibility of refrigerant freezing, as well as facilitating a refrigerant management scheme.

摘要： Method and apparatus for liquefying a hydrocarbon stream. A liquefaction system comprises at least an NGL recovery system 12, a main refrigerant circuit 42 and a first refrigerant circuit 100, a pressure reduction device 52 followed by an end gas/liquid separator 62. The main refrigerant circuit 42 comprises at least one or more main refrigerant compressors 45, 45a, 45b, and the first refrigerant circuit comprises one or more first refrigerant compressors 101. A hydrocarbon feed stream 10 is passed through the NGL recovery system 12 to produce a methane-enriched overhead stream 20, which is subsequently cooled and liquefied by the first and second refrigerant circuits. The pressure of the liquefied stream is reduced and the resulting mixed-phase stream 60 is passed through the end gas/liquid separator 62 to provide an end gaseous stream 70 and a liquefied hydrocarbon product stream 80. The loading power of the one or more main refrigerant compressors and the one or more first refrigerant compressors is maximized to their maximum load by adjusting temperature of the liquefied stream to change the amount of end gaseous stream and by controlling an amount of the end gaseous stream being fed into the methane-enriched overhead stream 20 in a recycle stream 90b.

摘要： Nitrogen is removed from a cryogenic hydrocarbon composition. A least a first portion of the cryogenic hydrocarbon composition is fed to a nitrogen stripper column. The nitrogen stripper column operates at a stripping pressure. A stripping vapour is passed into the nitrogen stripper column, comprising at least a stripping portion of a compressed process vapour that has been produced from the nitrogen-stripped liquid which has been depressurized after drawing it from the nitrogen stripper column. Reflux is generated involving partially condensing overhead vapour of the nitrogen stripper column by passing heat from the overhead vapour to an auxiliary refrigerant stream at a cooling duty. An off gas consisting of a, non-condensed, vapour fraction from the overhead vapour is discharged. The cooling duty is adjusted to regulate a heating value of the vapour fraction being discharged.

摘要： A partially condensed hydrocarbon feed stream is sent to a column. An overhead vapour hydrocarbon stream from the column is then partially condensed by indirect heat exchanging against an expanded cooling fluid flowing through a first section of a cold side heat exchanging channel. The cooling fluid consists of a mixed refrigerant composition, and liquid from the expanded cooling fluid is continuously transformed to vapour thereby forming a residual liquid portion of not evaporated expanded cooling fluid. The residual liquid is used to progressively condense the hydrocarbon feed stream to produce the partially condensed hydrocarbon feed stream that is sent to the column, by allowing the hydrocarbon feed stream to lose heat to the residual liquid passing through a second section of the cold side heat exchanging channel. The liquid component that is condensed out of the overhead vapour hydrocarbon stream is used as reflux for the column.

摘要： Disclosed herein is a natural gas liquefaction process using a single refrigeration cycle adopting a mixed refrigerant, and therefore having a simple structure and thus a compact system which is easy to operate, and further, after the mixed refrigerant is separated into two refrigerant parts, the two refrigerant parts are not mixed with each other but go through condensing (cooling), expanding, heat-exchanging, and compressing stages individually, and thus, optimal temperature and pressure conditions are applied to each of the separated refrigerant parts to increase efficiency of the liquefaction process.
摘要翻译：本文公开了使用采用混合制冷剂的单个制冷循环的天然气液化方法，因此具有简单的结构，因此具有易于操作的紧凑的系统，此外，在将混合的制冷剂分离成两个制冷剂部分之后，两个制冷剂部分不会彼此混合，而是分别通过冷凝（冷却），膨胀，热交换和压缩阶段，因此，对每个分离的制冷剂部分施加最佳的温度和压力条件，以提高液化过程。
