Abstract:
The invention relates to a continuous process for removal of acid gas, such as carbon dioxide (CO2) from a fluid stream, such as natural gas comprising mainly hydrocarbons, by means of a absorbent medium in a rotating absorption zone. Subsequently, the acid gas is desorbed in a rotating desorption zone from the absorbent medium to allow the absorbent medium to be recirculated and the acid gas is removed for storage or drying and processing. This process can be carried out continuously, as the absorption medium is re-used.
