Abstract
Abstract The absorption of gas by a fluent material conducted through a gas transfer apparatus is enhanced by continuous pressurization while it is being recirculated alternately through two closed loops. Flow chambers in each of said closed loops, within which the fluent material is gasified during each cycle are alternately switched out of the closed loops so that the gasified fluent material accumulated therein may be displaced by flow from the source under a lower pressure than that of the fluent material trapped in the closed loops.
