Abstract
Provided are a method of regenerating an inorganic porous gas separation membrane and a regeneration device for an inorganic porous gas separation membrane, which can restore the separation capability of the inorganic porous gas separation membrane in a simple and effective manner. A method of regenerating an inorganic porous gas separation membrane according to one embodiment includes bringing a cleaning fluid at a pressure of from 3 MPaG to 30 MPaG into contact with a used inorganic porous gas separation membrane containing at least a part of components of a treated gas.
Claims13
A method of regenerating an inorganic porous gas separation membrane having a flat membrane shape or a tube shape, the method comprising bringing a cleaning fluid at a pressure of from 5 MPaG to 30 MPaG into contact with a used inorganic porous gas separation membrane containing at least a part of components of a treated gas.
(canceled)
A regeneration device for an inorganic porous gas separation membrane having a flat membrane shape or a tube shape, the regeneration device comprising:
- a gas separation membrane module including:
- a housing including a cleaning-fluid feed port and a used-cleaning-fluid discharge port;
- and
- an inorganic porous gas separation membrane accommodated in the housing;
- and
- a cleaning-fluid feed device that is in fluid communication with the cleaning-fluid feed port.
