摘要： Enriched oxygen from a pressure swing adsorption system and air are blended to provide oxygen enriched air of desired purity, particularly for use at flow rates between those for which liquid oxygen and on-site cryogenic air separation plants are desirable.

摘要： A membrane system is positioned within an insulated enclosure heated to maintain superheat conditions for the feed gas to the system, wherein individual membrane modules are not insulated. The feed gas compression heat is desirably used to supply the superheat to the feed gas within the insulated enclosure.

摘要： Wet feed air to, or high purity nitrogen from, a pressure swing adsorption system is dried in a dryer membrane system preferably operated with a countercurrent flow path. Drying is enhanced by the use of a purge gas on the permeate side of the membrane, with waste gas from the pressure swing adsorption system or a portion of the dry, high purity nitrogen product gas being used as purge gas.

摘要： A shell and tube heat exchanger module which can be easily combined with other such modules to effect a close packed arrangement and which allows condensation of a vapor stream containing a non-condensible fraction without allowing a vapor buildup. The heat exchanger is particularly suitable as a main condenser in a cryogenic air separation process.
