DEODORIZING DESULPHURIZATION OF NATURAL GAS BY MEANS OF MEMBRANE CONTACTOR Russian patent published in 2017 - IPC B01D53/14 B01D53/22 B01D69/08 C10L3/10 

FIELD: chemistry.

SUBSTANCE: method of deodorizing desulphurization of natural gas to the specifications for liquefied natural gas includes the introduction of natural gas into the internal channel of the membrane contactor, the introduction of an absorption solvent into the intertubular space of the membrane contactor and the removal of carbon dioxide and hydrogen sulfide with an absorption solvent from natural gas, to the desulfurized natural gas containing less than 50 volume parts per million of carbon dioxide and less than 4 volume parts per million of hydrogen sulfide.

EFFECT: improved method for purifying natural gas, including minimizing the consequences caused by movement and instability of the process, for example, during processing at sea.
