ABSORPTION MACHINE WITH MULTI-TEMPERATURE COMPARTMENTS
A reactor arrangement and process for indirectly contacting a reactant stream with a heat exchange stream uses an arrangement of corrugated heat exchange plates to control temperature conditions by varying the number and/or the arrangement of the corrugations along the plates. The reactor arrangement and process of this invention may be used to operate a reactor under isothermal or other controlled temperature conditions. The variation in corrugation arrangements within a single heat exchange section is highly useful in maintaining a desired temperature profile in an arrangement having a cross-flow of heat exchange medium relative to reactants. The corrugations arrangement eliminates or minimizes the typical step-wise approach to isothermal conditions.

PCT No. PCT/SE93/01072 Sec. 371 Date Jun. 5, 1995 Sec. 102(e) Date Jun. 5, 1995 PCT Filed Dec. 15, 1993 PCT Pub. No. WO94/14017 PCT Pub. Date Jun. 23, 1994. An absorption machine and a method for operating the machine are disclosed. The absorption machine comprises an absorber with heat-exchanger assemblies and a generator with heat-exchanger assemblies, the generator and the absorber being interconnected by two conduits. The absorber and/or generator are divided into at least two compartments which are in communication with one another and in which the different heat-exchanger assemblies have separate inlets and outlets. By means of the inventive machine, heating media of different temperatures can be obtained from the absorber and waste heat of different temperatures can be used in the generator.
Jan Shihming N; White Dave Carlsbad, CA, UNITED STATES assigned to Solar Turbines Incorporated The present air conditioning system bleeds high pressure, hot, compressed air from the compressor section of a gas turbine engine and passes the high pressure flow of air directly through a single heat exchanger, through a flow control valve, is used to drive a supersonic turbine device, exits the supersonic turbine device as a low pressure, cooled flow of air and passes through a water separator prior to being used to cool the cabin zone. The primary advantages of the improved air conditioning system includes the elimination of the necessity for pressure regulation and only one heat exchanger is required. Furthermore,the improved air conditioning system is modulely designed and allows for a more flexibility, enabling the components to be more selectively located.
5600970 CRYOGENIC RECTIFICATION SYSTEM WITH NITROGEN TURBOEXPANDER HEAT PUMP Drnevich Raymond F; Prosser Neil Clarence Center, NY, UNITED STATES assigned to Praxair Technology Inc A cryogenic rectification system which can operate at elevated pressure without encountering a severe separation efficiency burden wherein additional column reflux is generated by an indigenous nitrogen heat pump circuit.
