The invention relates to a method for cooling rising vapour ( 3 ) in a desorption column ( 2 ) by means of a condenser, which is situated at the head of the desorption column, is configured as an indirect heat exchanger and is traversed by a coolant ( 1 ). According to said method, the coolant enters at the bottom of the condenser ( 1 ) and flows upwards through conduits ( 8 ) that are arranged vertically in the condenser. The coolant is enriched with hydrogen sulphide prior to its entry into the condenser ( 1 ) and after the absorption of heat, escapes as an overflow ( 6 ) from the top of the condenser ( 1 ) through upper openings ( 10 ) of the conduits ( 8 ). The invention also relates to a desorption column ( 2 ) for carrying out said method.
