A membrane system controller and control method for maximizing retentate product output and incorporating compressor load detection apparatus and process parameter instrumentation for feeding essential monitoring information to a control unit. Product output maximization is accomplished by increasing the membrane operating temperature during periods when compressor capacity is underutilized.

[ We claim:] [1.] A method of controlling a permeable membrane system for separating at least one gas product from a gaseous mixture to utilize excess capacity from a membrane system feed compressor operating at a predetermined optimal load for feeding said gaseous mixture to a membrane unit having a controllable heating means to establish a variable operating temperature and a permeable membrane having a permeability and product gas supply rate dependent upon said operating temperature, said method including the steps of:detecting the actual loading of said compressor;determining the level of compressor capacity that is unused; andraising said operating temperature, when said determining step indicates unused compressor capacity, to increase said membrane permeability.
