Abstract
A method and apparatus for selectively removing H.sub.2 S from a gas stream containing H.sub.2 S and CO.sub.2 and having a variable flow rate. The absorption system is divided into at least two absorption columns which are connected in parallel and contain at least two individual absorption volumes connected in series in which the gas and absorbent solution can countercurrently contact each other. The absorption system has means to control the passage of the fluid streams to each absorption column and the absorbent solution through the individual absorption volumes.
