Process and installation for providing a fluid mixture containing at least 10% carbon monoxide
摘要：
In a process for producing a mixture containing at least 10% carbon monoxide (73) by cryogenic separation of a feed gas containing at least carbon monoxide, hydrogen and methane, the feed gas (1) is separated to produce a first gas enriched in hydrogen (71), the feed gas is scrubbed in a methane wash column (7), a carbon monoxide enriched stream (13) from the bottom of the methane wash column is separated (19) to produce a stream further enriched in carbon monoxide (23), the stream further enriched in carbon monoxide is separated to form a carbon monoxide rich stream (31,49) and a liquid methane stream (27), at least part (72) of the carbon monoxide rich stream is mixed with the first gas enriched in hydrogen to form the mixture containing at least 10% carbon monoxide as a product stream.
摘要（中）：

在通过低温分离至少含有一氧化碳，氢气和甲烷的进料气体来生产含有至少10％一氧化碳（73）的混合物的方法中，进料气体（1）被分离以产生富含氢气的第一气体 （71）中，将进料气体在甲烷洗涤塔（7）中洗涤，分离甲烷洗涤塔底部的一氧化碳浓缩物流（13）（19）以产生进一步富集一氧化碳（23 ），进一步富集一氧化碳的物流被分离以形成富一氧化碳流（31,49）和液态甲烷物流（27），所述一氧化碳流的至少一部分（72）与第一气体 富含氢气以形成含有至少10％一氧化碳作为产物流的混合物。
