The scrubbing solution has a boiling point above 100°C under atmospheric pressure and is used for gas purification at temperatures from 5 to 70 °C and is thus laden with at least CO2 and H2S. For regeneration, the laden scrubbing solution under a pressure of at least 2 bars and at a temperature of at least 60°C is supplied to an expansion zone and is expanded therein, A flashed-off gas which is rich in H2S is withdrawn from the expansion zone. The scrubbing solution from the expansion zone is subjected to a hot regeneration, by which the scrubbing solution at a temperature below its boiling temperature is stripped with an inert gas so that its residual loading is substantially removed. Mixed gases which contain inert gas are withdrawn from the hot regeneration and are contacted with scrubbing solution.
