Abstract
The present invention relates to a process for the selective extraction treatment of a gaseous hydrocarbon mixture containing 5 to 3000 ppm (parts per million) by volume of hydrogen sulfide and 0.3 to 3% carbon dioxide, in order to obtain a purified gas containing less than 4 ppm by volume hydrogen sulfide and less than 2% carbon dioxide. The gaseous hydrocarbon mixture is submitted to a series of counter-current washings by contact with a tertiary amine aqueous solution in an absorption zone from which is drawn a liquid effluent enriched in hydrogen sulfide.
