Abstract
A membrane gas generator, which contains: a) a feed stream compressor having a feed stream input, b) a heat source downstream of the feed stream compressor, and in fluid connection therewith, c) a heat accumulator downstream of the heat source, and in fluid connection therewith; and d) at least one membrane with a permeate side and a non-permeate side downstream of the heat accumulator.
Claims17
A method of rapidly restarting a membrane nitrogen generator which is operated non-continuously, thereby reaching operating temperature in a reduced amount of time, said generator comprising feed stream compressing means having feed stream input means;
- heat source means downstream of said feed stream compressing means, and in fluid connection therewith;
- heat accumulator means downstream of said heat source means, and in fluid connection therewith;
- and at least one membrane with a permeate side and a non-permeate side downstream of said heat accumulator means;
- said method, comprising:
- a) storing a portion of heat provided by said heat source means during operation of the generator in said heat accumulator, and
- b) restoring heat to the generator from said heat accumulator means after said generator has been down and upon restarting said generator.
