Abstract
A method for regenerating a spent alkanolamine absorbing solution containing absorbed H2S and CO2 in two desorption stages to produce two separate acid gas streams. The first acid gas stream that contains substantially all of the H2S is sent to a sulfur recovery system and the second acid gas stream that is primarily CO2 is vented to the atmosphere. The desorption stages are connected in series and both are operated at substantially the same above-atmospheric pressure within the range of 8-12 psig (1.54-1.82 atm abs).
