Abstract
A process and an apparatus for separating desired clathrate forming gases from a gas mixture containing the desired clathrate forming gases. The process includes providing a stream of the gas mixture, contacting the stream of the gas mixture with an aqueous solvent to form a solid clathrate hydrate suspension in the aqueous solvent. The forming of the solid clathrate hydrate suspension in the aqueous solution causing the gaseous stream to be thereafter leaner in the desired clathrate forming gases. The solid clathrate hydrate suspension and the aqueous solution are subjected to an elevated temperature and to a reduced pressure to produce a product gaseous stream which is richer in the desired clathrate forming gases.
