    摘要： A gas processing system having cyclicly reactivated adsorbers normally operable in a low temperature range, a cold accumulator for refrigeration storage, and valved conduits interconnecting the adsorbers, accumulator and a source of reactivation gas, providing for isolation of an adsorber for reactivation; transfer of the adsorber refrigeration to the accumulator by a reactivation gas stream; reactivation and purging of the adsorber by heated reactivation gas; cooling of the adsorber by reactivation gas at ambient temperature; retransfer of the refrigeration from the accumulator to the adsorber by a counterstream of reactivation gas; and supplemental final cooldown of the adsorber by cold system gas.

    摘要： The present invention relates to a thermally regenerable adsorptive process for the purification of a feed air, wherein the feed air is contacted with a solid adsorbent to remove at least water and carbon dioxide, wherein, periodically, the solid adsorbent is thermally regenerated by contacting the solid adsorbent with a regeneration gas stream which is essentially free of at least water and carbon dioxide, wherein the regeneration gas is a nitrogen-enriched stream removed from an elevated pressure air separation unit fed with the purified feed air, characterized in that the removed nitrogen-enriched stream is compressed in a multiple staged compressor and that the regeneration gas is a portion of the nitrogen-enriched stream which is removed from an interstage of the multiple stage compressor and then contacted with the solid adsorbent. The process is particularly suited for use with a solid adsorbent selected from the group consisting of 13X zeolite, silica gel, A zeolite, Y zeolite, mordenite, chabazite and mixtures thereof. Finally, the process of the present invention can comprise recycling the regeneration gas after contact with the solid adsorbent to one of the stages of the multiple stage compressor, preferably, from the stage from which it was removed.

    摘要： Liquid oxygen and/or liquid nitrogen are made by removing carbon dioxide and water vapor from air, compressing the purified air in a re-cycle compressor and dividing the purified compressed air into first and second streams. Part of the first stream is expanded in a first expander and the refrigeration produced is used to cool both the first and second streams in a first heat exchanger. On leaving the first heat exchanger, the second stream is expanded in a second expander and the refrigeration produced is used to liquify at least part of the remainder of the first stream. The liquid stream is expanded and introduced into a fractionation column from which liquid nitrogen and/or liquid oxygen can be withdrawn. Expanded air from the first and second expanders is returned to the re-cycle compressor although part of the expanded air from the second expander is preferably introduced into the fractionation column. The invention is particularly suited to installations producing in excess of 100 tons of liquid per day and, at this size, preferred designs offer an estimated 51/2 to 9% power savings over the known prior art.
