A process for the removal of acid gases from pressurized, compounds with acid contaminated natural gas and recovering the remote comprise acid gases to an elevated pressure level

摘要

The present invention relates to a process for the acid gas removal from pressurized, with sulfur compounds contaminated natural gas, with· the natural gas to 5, first of all into the acid gas absorption stage is conducted, where the sulfur components as well as possibly further components acting solution by means of a physical be absorbed,· the absorption product is heated,· the absorbate in a high pressure - flash stage, where the resulting mixture of acid gas - poor absorbent acid gas is separated from one another and desorbed,· the desorbed acid gas is cooled and the evaporated absorbent from the acid gas stream is condensed out,· the acid gas - arms absorbent from the high pressure - flash stage in a gas - stripping stage by means of stripping gas is freed from oxygen, which is of a gas and the resulting laden stripping gas is cooled and in the acid gas absorption stage is conducted, and· the resulting absorption medium is cooled and in the circuit in the acid gas absorption stage is returned.
