Abstract: An absorption system powered by low temperature heat for producing at least one of refrigeration and power is disclosed, wherein a low-pressure drop heat reclaimer 1 reclaims heat from the source into a heating agent, which in turn supplies heat to the absorption cycle desorber 5 via internal coils 7. The extra temperature differential normally present in closed cycle heating systems is avoided by using the absorption working fluid as the heating agent, in an integrated system.

Abstract: An absorber for absorbing a vapor into a sorbent liquid comprised of a sequential plurality of highly effective and intensified locally cocurrent sorptions, but with non-cocurrent flow of vapor and liquid between the individual sorptions. The structure containing the locally cocurrent upflow is preferably comprised of enhanced heat transfer surface, making the sorption diabatic, further enhancing the intensification, and improving the sorption efficiency. Referring to FIG. 1, vertical cylinders (1) and (2) form an annulus which is divided into multiple compartments by partitions. Vapor is injected into the bottom portion of each compartment by injection ports (10), resulting in cocurrent upflow absorption. The compartments are pressure equalized with a common vapor space via equalization ports (6). This approach to absorption can be accomplished in a vertical cylindrical annulus as described above, in a horizontal cylindrical annulus, in plate fin exchangers, and others.

Abstract: The invention discloses process and apparatus for increasing the efficiency of subambient cascaded .fractional distillations such as air separation, ethane-ethylene separation, or nitrogen rejection from natural gas. The improvement provides an advantageous means of generating the optimal amount of intermediate reflux liquid for both rectifications in the cascade. Referring to FIG. 4, a latent heat exchanger (415) is provided in which a liquid from the HP rectifying section (403) of the cascade exchanges latent heat with a minor fraction of the feed gas. The condensed feed is then split by two valves (409 and 410) into respective intermediate reflux streams for both parts of the cascade (402 and 403).

Abstract: The argon recovery obtainable from a dual pressure cryogenic air distillation plant for production of high purity oxygen is increased beyond present levels without offsetting incurrence of detriments such as lower O.sub.2 pressure, lower O.sub.2 or N.sub.2 recovery, less liquid recovery, or increased energy. This is done by providing an intermediate reflux condenser (component 8 of FIG. 1) in the argon sidearm 2b, and providing liquid N.sub.2 via valve 9 to said condenser, thereby increasing the reboil up both argon stripper 2a and the lower section of 2b proportional to the amount of LN.sub.2 evaporated in 8.

Abstract: This invention makes possible a substantial improvement in the distillation column efficiencies of a cryogenic air separation process while still retaining high reboil rates through the argon stripping section of the low pressure column. Those advantages result in a lower energy requirement for separating air while still yielding medium to high oxygen purity. In a triple pressure column arrangement, the medium pressure column efficiency is increased by reboiling it at two or more locations by latent heat exchange with both the high pressure and low pressure columns. The LP column vapor which reboils the MP column is taken from above at least part of the argon stripper, to maintain a high reboil rate through the stripper.

Abstract: The invention comprises solution compositions suitable for absorbing and desorbing useful quantities of water vapor at high boiling point elevations, and, hence, which are useful in conjunction with H.sub.2 O as the absorbent pair in absorption cycle heat pumps. The nonaqueous component of the solution is comprised of at least 35 mole percent LiNO.sub.3 and at least 35 mole percent alkali nitrite. The absorbent is particularly useful in high temperature absorption cycles, i.e., with maximum temperatures in the range of 130.degree. C. to 260.degree. C. or even higher.

Abstract: The invention provides a means for reducing the energy consumed by thermally activated separation processes such as fractional distillation. This is done by recovering at least part of the reject heat from such processes and upgrading it for recycle back to input heat. The upgrading is accomplished by another low temperature source of heat which may also be the separation process reject heat. A simple and reliable heat pump using the reverse absorption principle is incorporated in the separation process to accomplish this upgrading.
