ABSTRACT:
In the absorption of acetylene from a crude gas mixture containing mostly C.sub.2 hydrocarbons, a substantially acetylene-free liquid C.sub.2 stream is introduced into a mixing chamber located in the column between the feed points for the crude gas mixture and the absorption agent. The C.sub.2 stream is distributed into fine droplets as it enters into accumulated absorption agent in the mixing chamber, so that foam is not formed in the absorption column. The mixing chamber can be formed of a mixing tank integrated with a plate.
