  • METHOD FOR SELECTIVE ABSORPTION OF HYDROGEN SULFIDE FROM A GASEOUS EFFLUENT COMPRISING CARBON DIOXIDE USING AN AMINE-BASED ABSORBENT SOLUTION COMPRISING A VISCOSIFYING AGENT
    Publication number: 20150290580
    Abstract: The invention is a method for selectively removing hydrogen sulfide H2S from a gaseous effluent comprising at least H2S and CO2. A stage of selective absorption of the hydrogen sulfide in relation to the CO2 is carried out by contacting the effluent with a solution comprising (a) water and (b) at least one nitrogen compound. The compound comprises at least one tertiary amine function or one hindered secondary amine function. The absorption selectivity is controlled by adding (c) a viscosifying compound to the absorbent solution.
