ABSTRACT:
A method and apparatus are provided for controlling the amount of purging that occurs within a membrane separation device. The membrane separation device includes a membrane separation component and sweep controlling component. Within the membrane separation component, a major portion of the non-permeate gas is sent out of the membrane separation device to work, while a minor portion is diverted for use as a sweep gas. The sweep gas is controlled by a valve that cycles with a device, such as a compressor. Thus, the membrane separation device is on when the compressor is on and is off when the compressor is off. As such, the membrane separation device is not required to sweep at all times.
