Abstract: An absorbent solution for absorbing and desorbing useful quantities of ammonia vapor is disclosed. The absorbent has much lower vapor pressure than water, and has a wider solubility field and higher crystallization limit than any previously known non-volatile absorbent for ammonia. It is useful in absorption cycle processes and apparatus requiring high lifts from temperatures well below freezing, e.g., in thermally actuated industrial refrigeration systems or cold-climate absorption heat pumps for space heating. The new absorbent is also useful with other ammonia-type vapor, e.g., monomethylamine.

Abstract: In a cryogenic air distillation process for producing medium-to-high purity oxygen plus optional coproduct argon, a new process sequence results in more efficient distillations at reduced supply pressure and full O.sub.2 recovery. Reforming to FIG. 2, a minor stream of supply air is additionally compressed by compander 204, cooled, and then reboils column 201 by total condensation in reboiler 205. The liquid air is split into two intermediate reflux streams, one for each column 201 and 202, valves 206 and 207, thereby improving the efficiency of both columns. The air condensing in 205 is somewhat hotter than that supplied to 202, due to its higher pressure, which permits a reduction in the main supply pressure.

Abstract: Process and apparatus are disclosed for increasing argon recovery in conjunction with cryogenic distillation of air to high purity oxygen. The increased argon recovery is obtained by incorporating one or more latent heat exchangers in the flowsheet at strategic disclosed locations and between specific fluids. The invention is particularly advantageous in conjunction with LOXBOIL flowsheets, which otherwise lose O.sub.2 recovery when argon recovery is increased.

Abstract: A process for the integration of a chemical absorption separation of oxygen and nitrogen from air with a combustion process is set forth wherein excess temperature availability from the combustion process is more effectively utilized to desorb oxygen product from the absorbent and then the sensible heat and absorption reaction heat is further utilized to produce a high temperature process stream. The oxygen may be utilized to enrich the combustion process wherein the high temperature heat for desorption is conducted in a heat exchange preferably performed with a pressure differential of less than 10 atmospheres which provides considerable flexibility in the heat exchange.

Abstract: This process provides an efficient means for distillative separation of a gas mixture at a temperature below ambient without requiring either a dual pressure or low pressure distillation column. The process comprises supplying the gas at an elevated pressure to a single pressure distillation column, work-expanding the column overhead gas to drive a heat pump compressor, compressing any of several gases in the heat pump compressor so as to effect phase change heat transfer between condensing column reflux and boiling column bottom product, and separately withdrawing the depressurized gaseous separation products.

Abstract: A continuous regenerative process for desulfurizing a hot reducing gas is disclosed. The gas is scrubbed by a sorbent containing MnO and Mn.sub.3 O.sub.4. The spent sorbent is regenerated by reacting the MnS with an excess of Mn.sub.3 O.sub.4, contained in oxidized sorbent. The oxidized sorbent is obtained by reacting part of the regenerated sorbent with air. In the regenerator the gaseous oxygen partial pressure is maintained below 10.sup.-6 atmospheres which allows the SO.sub.2 partial pressure to be maintained above 1 atmosphere without causing sulfation.
