摘要：
A process for the recovery of propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled and/or expanded to partially condense it, then separated to provide a first vapor stream. The first vapor stream is directed into a contacting device whereby a third vapor stream and a C3-containing liquid stream are formed. The C3-containing liquid stream is directed to a distillation column wherein a second vapor stream is separated to recover a product containing the major portion of the C3 components and heavier hydrocarbon components. The second vapor stream is directed into heat exchange relation with the third vapor stream to cool the second vapor stream and condense at least a part of it, forming a condensed stream. At least a portion of the condensed stream is directed to the contacting device to intimately contact the first vapor stream; the remaining portion of the condensed stream is supplied to the distillation column as its top feed. The quantities and temperatures of the feeds to the contacting device and the distillation column are effective to maintain the overhead temperatures of the contacting device and the distillation column at temperatures whereby the major portion of the desired components is recovered.
摘要（中）：
公开了从烃气流中回收丙烷，丙烯和较重烃组分的方法。 将物流冷却和/或膨胀以部分地冷凝，然后分离以提供第一蒸气流。 将第一蒸汽流引导到接触装置中，由此形成第三蒸气流和含C3的液体流。 将含C3液体物流引导至蒸馏塔，其中分离第二蒸气流以回收含有主要部分的C3组分和较重烃组分的产物。 第二蒸汽流被引导与第三蒸气流的热交换关系，以冷却第二蒸气流并冷凝其至少一部分，形成冷凝流。 至少一部分冷凝流被引导到接触装置以紧密接触第一蒸气流; 冷凝流的剩余部分作为其顶部进料供应到蒸馏塔。 进料到接触装置和蒸馏塔的数量和温度有效地将接触装置和蒸馏塔的塔顶温度保持在温度，从而回收所需组分的主要部分。
