通过低温蒸馏生成和分离氢氧化碳混合物的方法

PROCESS FOR GENERATING AND SEPARATING A HYDROGEN-CARBON MONOXIDE MIXTURE BY CRYOGENIC DISTILLATION
摘要：
In a process for generating and separating a syngas, a syngas (15) containing less than 2.3% methane is generated from a feed gas, the syngas containing hydrogen and carbon monoxide is purified by at least one treatment process (17, 21) in order to produce a purified syngas (23), and the syngas is separated by cryogenic distillation in a plant (25) comprising at least one methane scrubbing column (29) in order to produce a hydrogen-enriched gas (39, 41) and/or a carbon monoxide-enriched gas (55), and the syngas is enriched upstream of the cryogenic distillation separation in order to obtain a syngas comprising more than 2.3% methane by sending a portion (11) of the feed gas to a treatment process downstream of the syngas generation step (15), without passing via the syngas generation unit.
摘要（中）：

在产生和分离合成气的方法中，从进料气体产生含有小于2.3％甲烷的合成气（15），含有氢气和一氧化碳的合成气按顺序通过至少一种处理方法（17,21）纯化 以产生纯化的合成气（23），并且在包含至少一个甲烷洗涤塔（29）的设备（25）中通过低温蒸馏分离合成气，以产生富氢气体（39,41）和/或 富含一氧化碳的气体（55），并且所述合成气富集在所述低温蒸馏分离的上游，以便通过将所述进料气体的一部分（11）送入所述进料气体的下游的处理过程来获得包含大于2.3％的甲烷的合成气 合成气产生步骤（15），而不经过合成气产生单元。
