ABSTRACT:
A pressure swing adsorption process and system for air separation includes a variable volume nitrogen product storage vessel, which is monitored to determine variations in user product demand. The processing cycle and individual processing steps are adjusted during periods of reduced demand to maintain a desired product purity and pressure, with power reduction and energy savings being achieved under turndown conditions.
