Abstract

Hydrogen sulphide is removed from gases, esp. natural gas, which contain hydrocarbons and also carbon dioxide, by using glycols, in a quantity of >=500 g/Nm3 as absorption agents. Pref., 700-800 g/Nm3 of triethylene glycol are used. The water content of the absorption agent is adjusted, before use, to 1-5 wt%; in particular, the gases obtained during regeneration at the head of the regeneration stage are cooled sufficiently to leave the water content of the absorption agent at this value by recondensation.
