Abstract
In the fractionation of a gaseous mixture, of hydrogen, methane, and carbon monoxide, comprising a cold methane wash to obtain a gaseous stream of hydrogen and a liquid stream of carbon monoxide and methane, the improvement wherein of the gaseous mixture prior to the methane wash is subjected to a continuous partial condensation at a temperature higher than the cold methane wash, thereby obtaining a gaseous phase fraction and a condensed liquid phase fraction; the gaseous phase fraction is conducted to the methane wash, and the condensed liquid phase fraction is conducted to a stripping column which produces a bottoms product stream of methane and an overhead product stream of hydrogen and carbon monozide. The continuous partial condensation can be conducted either in a single stage or in multiple stages.
