A process for simultaneous separation of carbon monoxide and carbon dioxide from a mixed gas stream comprising contacting the gas stream with a liquid nitrile absorbent having the general formula R-CN wherein R is selected from alkyl radicals having from one to five carbon atoms and alkoxyalkyl radicals having from two to ten carbon atoms, maintaining the temperature of the gas stream during separation at a temperature below the decomposition temperature of the nitrile absorbent and removing the nitrile absorbent, carbon monoxide and carbon dioxide mixture from contact with the mixed gas stream.
一种从混合气体流中同时分离一氧化碳和二氧化碳的工艺,包括将气体流与具有通式 R-CN 的液态腈吸收剂接触,其中 R 选自具有 1 至 5 个碳原子的烷基和具有 2 至 10 个碳原子的烷氧基烷基;在分离过程中将气体流的温度保持在低于腈吸收剂分解温度的温度;将腈吸收剂、一氧化碳和二氧化碳混合物从与混合气体流的接触中移除。
