Abstract
The invention relates to a method for cooling rising vapor (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.
Claims2
Method for cooling rising vapors (3) in a desorption column (2) by means of a condenser (1) disposed at the head of the desorption column (2), configured as an indirect heat exchanger, through which cooling water flows, whereby the cooling water enters into the condenser (1) at the bottom and flows upward through vertical channels (8) disposed in the condenser (1), wherein cooling water containing hydrogen sulfide is used, wherein the cooling water exits as an overflow (6), by means of top-side openings (10) of the channels (8), at the top of the condenser (1), after the heat absorption has occurred, and wherein the overflow (6) flows into the desorption column (2).
