摘要： An integrated steam-ammonia power cycle is disclosed which achieves a close match to a glide heat source such as exhaust from a gas turbine, and which also eliminates sub-atmospheric pressure operation. With reference to Figure 1, the exhaust heats in sequence steam superheater (107); steam boiler (105); feedwater preheater (104) plus ammonia superheater (103); and ammonia preheater (102). Steam is expanded to at least (17) psia in turbine (108), then condensed to boil ammonia in boiler (110). Superheated ammonia is expanded in turbine (112), and condensed in condenser (114). Feed ammonia is preheated in at least two parallel preheaters.

摘要： An absorber for absorbing a vapor into a sorbent liquid comprising vertical cylinders (1, 2) forming an annulus which is divided into multiple compartments by partitions consisting of cross-members (7) and perpendicular members (5). Vapor is injected into the bottom portion of each compartment by injection ports (10), resulting in concurrent upflow absorption. The compartments are pressure equalized via equalization ports (10), and may be in thermal contact with a heat exchange compartment (12). Liquid flows through the compartments in a serial pathway through liquid transport passages (4). The absorber may be embodied in geometries other than vertical cylinders.

摘要： Method and apparatus for achieving high yields of high purity N2 and optional coproduct O2 at lower energy and capital cost than heretofore possible are disclosed. Referring to Figure 1, in a dual pressure configuration comprised of a rectifier (105) and a column (102), warm companded air from a compressor (118) provides bottom reboil at the reboiler (103), and the liquid air is split to reflux both columns. The refrigeration expander (112), driven by expansion of waste O2, provides the power for the compressor (118). Also kettle liquid is distilled into two vapor streams by a contact zone (107) before feeding to the column (102).

摘要： A high efficiency open-cycle absorptive approach to compressing steam or other vapor is disclosed, especially useful for industrial evaportion via recompression. Referring to FIG. 1, low pressure steam from evaporator 1 is absorbed in an aqueous absorbent solution so as to release heat in both absorber 7 and GAX exchanger 8. External heat is applied to generator 12. Steam at higher pressure is desorbed from both gnerator 12 and GAX exchanger 8, and used to heat evaporator 1. Absorber 7 heat is also used to heat and evaporate the mixture undergoing evaporation.

摘要： 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 pressures and full O2 recovery. A minor steam of supply air is additionally compressed by compander (104), cooled, and then reboils column (101) by total condensation in reboiler (105). The liquid air is split into two intermediate reflux streams, one for each column (101) and (102), valves (106) and (107), thereby improving the efficiency of both columns. The air condensing in reboiler (105) is somewhat hotter than that supplied to column (102), due to its higher pressure, which permits a reduction in the main supply pressure.

摘要： Improved means of producing the refrigeration required for any fractional distillation air separation process. The improved refrigeration technique causes the distillation columns to operate more efficiently, and thereby permits increased recovery and/or purity of product at lower energy input. Refrigeration air is partially expanded in expander (313), then condensed by exchanging latent heat with depressurized kettle liquid in (314), and the resulting liquid air is split and used to reflux both columns (307) and (305) via pump (316) and valve (315), respectively.
