Abstract
A membrane module assembly adapted to provide a flow path for the incoming feed stream that forces it into prolonged heat-exchanging contact with a heating or cooling mechanism. Membrane separation processes employing the module assembly are also disclosed. The assembly is particularly useful for gas separation or pervaporation.
Claims20
A membrane module assembly comprising:
- (i) a membrane module, having a feed end for receiving a feed stream;
- (ii) an inner housing having feed, residue and permeate ports, said membrane module being mounted in said inner housing such that said feed port is distal from said feed end;
- (iii) a means, at least partially encasing said inner housing, for heating or cooling said housing.
A membrane separation process comprising:
- (a) providing a membrane module assembly comprising;
- (i) a membrane module, having a feed end for receiving a feed stream;
- (ii) an inner housing having feed, residue and permeate ports, said membrane module being mounted in said inner housing such that said feed port is distal from said feed end;
- (iii) a means, at least partially encasing said inner housing, for heating or cooling said housing;
- (b) heating or cooling said housing;
- (c) passing said feed stream into said assembly through said feed port and flowing it substantially along an inner surface of said membrane housing to said feed end;
- (d) separating said feed stream into a residue stream and a permeate stream in said membrane module.
