摘要
The method of selective removal of hydrogen sulfide relative to carbon dioxide from a gas mixture containing at least hydrogen sulfide HS and carbon dioxide CO, comprising the step of bringing said gas mixture into contact with an absorbent solution containing preferably consisting of at least one amine, water and at least one CC-thioalkanol. The use of the specified absorbing solution for the selective removal of hydrogen sulfide relative to carbon dioxide from a gas mixture containing at least hydrogen sulfide and carbon dioxide. The use of at least one CC-thioalkanol as an additive in an absorbent solution containing, preferably consisting of at least one amine and water, to increase the selectivity of said absorbing solution to remove hydrogen sulfide relative to carbon dioxide from a gas mixture containing at least hydrogen sulfide and carbon dioxide.
