A system that includes an equipment package for separating nitrogen from air to produce enhanced oxygen air for use by divers. The package is combined with a pressure storage tank for air that is coupled to the package. A pressure storage tank is provided for enhanced oxygen air. A fill station including a high pressure gauge and a high pressure oxygen sensor is provided to fill divers' tanks. A compressor receives the enhanced oxygen air from the package and delivers high or low pressure enhanced oxygen air to the pressure storage tank via a pressure fi...
[ I claim:] [1.] A process for supplying enhanced oxygen air for use by divers as a life support system comprising the steps of:(a) providing a supply of pressurized feed air;(b) reducing the pressure of said pressurized feed air, with cooling, to 50-400 p.s.i.g.;(c) modifying the temperature of the reduced pressure feed air to a preselected value resulting in temperature modified, reduced pressure feed air;(d) separating nitrogen from said temperature modified, reduced pressure feed air by a permeable membrane gas separation system using a bundle of hol...
