PRESSURE SWING CYCLES FOR GAS SEPARATIONS

摘要

A gas separation apparatus and cycle in which a compressor (4) is the source of a pressure differential (5 and 6) and flow regulator means (V1-V6) cyclicly direct the flow of source gas (9) to and purge gas (11) from an adsorbent bed (1). A separated gas component is directed from the bed (1) to a product vessel (7) for pressure regulated (V7) dispensation (10). The compressor (4) and product vessel (7) together provide purge gas flow through the adsorbent. The apparatus and cycles can be ganged to provide multi-component gas separations.
