Zusammenfassung:	A method and apparatus for selectively removing H2S from an H2S and CO2 containing gas stream which has a variable flow rate. The absorption apparatus is divided into two connected individual absorption volumes in which the gas and absorbent solution can countercurrently contact each other and has means to control the passage of the fluid streams through the individual absorption volumes.
