ABSTRACT:
In the absorption of acetylene from a crude gas mixture containing mostly C.sub.2 hydrocarbons by scrubbing with an absorbing agent, an externally produced mixture of about 10-70% by weight acetylene-free C.sub.2 hydrocarbons and about 30-90% by weight absorption agent is introduced in the absorption column, in order to prevent the formation of foam. The mixture is produced in a static mixer outside the absorption column, and is supplied from outside the column to a mixing tank installed between two plates within the column.
