A system for generating oxygen enriched air includes a compressed air supply for supplying compressed air and a permeable membrane gas separation system for separating a nitrogen gas component and an oxygen enriched air component from the compressed air. An oxygen analyzer is provided to detect an oxygen concentration in the oxygen enriched air component. The nitrogen gas component is divided, by a vortex tube, into a cold gas stream and a hot gas stream, and solenoid valves are actuated to modify a flow path of the compressed air through the cold gas st...
[ What is claimed is:] [1.] A process of generating oxygen enriched air for subsequent compression and filling of a diving tank used in underwater respiration by a diver in a diver underwater life support system comprising the steps of:(a) using a permeable membrane oxygen enriched air and nitrogen gas separation system to effect separation of air into a nitrogen gas component and a directly breathable, oxygen enriched air component;(b) introducing air at a pressure of 50-600 p.s.i.g. and a predetermined temperature at an inlet of said gas separation sys...
