摘要:
A method for generating refrigeration, especially over a wide temperature range including cryogenic temperatures, wherein a non-toxic, non-flammable and low or non-ozone-depleting mixture is formed from defined components and maintained in variable load form through compression, cooling, expansion and warming steps in a refrigeration cycle.
摘要:
A cryogenic air separation process for producing liquid oxygen and other liquid products wherein refrigeration generation for the process is decoupled from the flow of process streams and is produced at least in part by at least on multicomponent refrigerant fluid refrigeration circuit.
摘要:
A system for generating refrigeration and providing the refrigeration into a cryogenic rectification plant wherein, in addition to refrigeration generated by turboexpansion, further refrigeration for the plant is generated by a recirculating multicomponent refrigerant in a refrigeration circuit.
摘要:
A method for more efficiently cooling and liquefying industrial gas wherein refrigeration for the cooling and liquefaction is generated using first and second defined multicomponent refrigerant fluids in separate refrigeration circuits to cover a wide temperature range from ambient to cryogenic temperature.
摘要:
A method for cleaning and recycling protective atmosphere for a float glass facility wherein contaminated protective atmosphere is cooled, preferably while scrubbing out particulates, compressed, and then purified by passage through a bed comprising water selective and hydrogen sulfide selective adsorbents.
摘要:
A cryogenic air separation plant or a combined pressure swing adsorption plant and membrane separation plant is integrated with a float glass manufacturing system wherein oxygen from the plant is used for oxy-fuel combustion in the melt furnace and nitrogen from the plant is used as a protective atmosphere in the float glass forming chamber.
摘要:
A method for the cryogenic separation of air having defined temperatures for condensed feed air passed into a double column system relative to liquid oxygen and preferably to shelf vapor, and wherein kettle liquid is not subcooled from the higher pressure column to the lower pressure column.
摘要:
A method for low temperature separation of fluids wherein the separation process is sustained by refrigeration generated by a recirculating multicomponent refrigerant fluid.
摘要:
A method for more efficiently liquefying industrial gas wherein refrigeration for the liquefaction is generated using a defined multicomponent refrigerant fluid and provided by a single flow circuit over a wide temperature range from ambient to cryogenic temperature.
摘要:
A method for liquefying an industrial gas wherein a portion of the requisite refrigeration is generated by a multicomponent refrigerant circuit and a portion is generated by turboexpansion of either a portion of the industrial gas or a portion of the multicomponent refrigerant.
