    • A process is described for separating the heavier hydrocarbons from a gaseous hydrocarbon feed wherein a first separator is employed to separate partially condensed gaseous feed and wherein the vapour portion undergoes work expansion and is fed to a fractionation column. The liquid portion is subcooled in heat exchange with the overhead vapour from the fractionation column, expanded, evaporated to provide refrigeration at a low temperature level, and fed to the fractionation column. The rewarmed residual vapour is subsequently compressed to a pressure suitable for export, with a portion of the compressed gas being cooled, condensed and recycled back to reflux the top section of the fractionation column.
      Also described is a process wherein a first separator is employed to separate partially condensed gaseous feed and wherein the vapour portion undergoes work expansion and is fed to a high pressure wash column. The liquid portion is expanded and fed to the base of the high pressure wash column. Bottoms liquid from the wash column is subcooled in heat exchange with the overhead vapour from a fractionation column, expanded, evaporated to provide refrigeration at a low temperature level, and fed to the fractionation column. Vapour from the high pressure wash column is partially condensed, with the liquid portion used to provide reflux to the high pressure wash column and the fractionation column.
      The processes are especially applicable to recovery of ethane and heavier components from natural gas. Overall process power requirements are reduced, recovery of the desired heavy hydrocarbons is increased or both of these effects are realised.
    • 描述了用于从气态烃进料分离较重烃的方法,其中使用第一分离器分离部分冷凝的气态进料,并且其中蒸气部分经历工作膨胀并进料至分馏塔。 液体部分与来自分馏塔的塔顶蒸气热交换过冷,膨胀,蒸发以在低温水平提供制冷,并进料至分馏塔。 随后将再热的残余蒸气压缩至适于出口的压力,一部分压缩气体被冷却,冷凝并再循环回到分馏塔的顶部部分。 还描述了一种方法,其中使用第一分离器来分离部分冷凝的气态进料,并且其中蒸气部分经历工作膨胀并进料到高压洗涤塔。 液体部分膨胀并进料到高压洗涤塔的底部。 来自洗涤塔的底部液体与来自分馏塔的塔顶蒸气热交换过冷,膨胀,蒸发以在低温水平提供制冷,并进料至分馏塔。 来自高压洗涤塔的蒸汽部分冷凝,液体部分用于向高压洗涤塔和分馏塔提供回流。 该方法特别适用于从天然气中回收乙烷和较重的组分。 总体处理能力要求降低,期望的重质烃的回收率增加或者这两种效应都实现。
