Abstract
A process for the removal of carbon dioxide, sulphur compounds, water and aromatic and higher aliphatic hydrocarbons from industrial gases. The sour gas components, water and hydrocarbons are removed from the gas to be treated by absorption at elevated operating pressure. At least one morpholine derivative is used as the absorbent. The absorbent laden with absorbed components is regenerated with the aid of a stripping gas. The stripping gas is generated by partial evaporation of the laden absorbent.
