Abstract: A method of liquefying a hydrocarbon-rich gas, wherein the gas (1) flows through a cascade of three refrigeration stages (E1, E2, E3), each stage comprising a refrigerant circuit and a compressor (V2, V3, V4), wherein at least part (3d) of the flow of refrigerant from the second circuit is used for the pre-cooling (E1) of the hydrocarbon rich gas in the first refrigeration stage. This balances the load on each of the compressors. By standardizing the drive units and compressors of the three coolant circuits, it is possible to maximize the attainable liquefaction capacity of the liquefaction process using tried-and-trusted drive units and compressors respectively. This method can be applied to mixed refrigerant cascades and circuits with a carbon dioxide pre-cooling circuit. This latter option has benefits for offshore use where large amounts of hydrocarbons are undesirable.
Abstract translation: 一种液化富烃气体的方法，其中气体（1）流过三个制冷级（E1，E2，E3）的级联，每级包括制冷剂回路和压缩机（V2，V3，V4），其中 来自第二回路的制冷剂流的至少一部分（3d）用于第一制冷级中的富含烃气体的预冷却（E1）。 这平衡了每台压缩机的负载。 通过对三个冷却剂回路的驱动单元和压缩机进行标准化，可以分别使用经过验证的驱动单元和压缩机来最大化液化过程的可达到的液化能力。 该方法可以应用于具有二氧化碳预冷却回路的混合制冷剂级联和回路。 后一种选择对于海水使用有益，其中大量的烃是不希望的。

Abstract: Method for liquefying a hydrocarbon-rich stream, especially a natural gas stream, comprises separating a first coolant mixture cycle (1-12) into a low boiling fraction (10) and a higher boiling fraction (2). The two fractions have different pressures and are fed to a pre-cooling unit (E1). Preferred Features: Pre-cooling of the hydrocarbon-rich stream is carried out in a wound heat exchanger. A second coolant mixture cycle (20-25) has a compressor (V2) with a pressure ratio of at least 10.
