SEPARATION DEVICE AND REGENERATION METHOD

摘要

This separation device 10 is provided with: a supply path 20 for supplying a gas to be processed; a membrane separation part 40 that is provided with a zeolite membrane 45; a permeated gas recovery path 60 for recovering a permeated gas that has permeated through the zeolite membrane 45; and a non-permeated gas recovery path 80 for recovering a non-permeated gas that has not permeated through the zeolite membrane 45. This separation device 10 is provided with a regeneration path 100 which has a regeneration function of regenerating the zeolite membrane, which has been used for separation, on site and performs a regeneration process. The zeolite membrane 45 selectively allows the permeation of carbon dioxide. Meanwhile, the gas to be processed contains a hydrocarbon-based combustible gas and carbon dioxide. The zeolite membrane 45 is regenerated in the regeneration path 100 by being supplied with a regeneration gas that contains heated air.
