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 low temperature separation of fluids wherein the separation process is sustained by refrigeration generated by a recirculating multicomponent refrigerant fluid.
摘要:
A system for producing high purity argon wherein crude argon produced in a cryogenic rectification plant is processed in a pressure swing adsorption unit. Residual gas from the pressure swing adsorption unit is recycled to the cryogenic rectification plant and high purity argon is cooled prior to recovery against oxygen-containing fluid which is subsequently passed into the cryogenic rectification plant.
摘要:
A cryogenic air separation process having improved flexibility and operating efficiency wherein refrigeration generation for the process is decoupled from the flow of process streams and is produced by one or more closed loop circuits.
摘要:
A system for cooling a fluid particularly to a cryogenic temperature wherein a multicomponent refrigerant fluid is partially condensed, the liquid used to generate refrigeration to cool the product by recycle into an upstream portion of the warming leg of the refrigeration circuit, and the vapor, having a different composition than the liquid, is used to generate refrigeration at a colder temperature for further cooling of the product.
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 cryogenic rectification system wherein some or all of the refrigeration necessary to drive the rectification is generated by providing a pulse to a gas and then passing the compressed gas to a pulse tube wherein the gas expands in a wave generating refrigeration at one end of the pulse tube for transfer into the rectification system.
