Abstract
Hydrogen sulfide enrichment procedure of acid gases, which contain hydrogen sulfide, CO2 and a hydrocarbon content of less than 5%, procedure in which the gases are counter-washed with an aqueous solution of methyldiethanolamine, called Summary MDEA, and the MDEA solution, charged with acid gas, is regenerated by entrainment with water vapor, characterized in that the proportion of the acid gas in CO2 drops below 10%, containing the extracted CO2 less than 2% of H2S, proceeding to a plurality of successive washes with the aid of the MDEA solution, the solution having a concentration in MDEA comprised between 2 N and 4 N and the ratio of the mass flow rate of the MDEA solution to the mass flow rate of acid gas, between 4 and 15, because the acid gas is made to conduct at the first contact of the first wash with the MDEA solution at a speed between 1 and 25 meters per second, because the gases are washed at temperatures between 20 and 60ºC and because the regeneration is conducted so that a gram of H2S per liter remains in the regenerated solution.
