The method can include the steps of: (a) providing a pressurized natural gas stream, a pressurized purge gas stream originating from a methanol plant, and a pressurized air gas stream comprising an air gas originating from the ASU; (b) expanding three different pressurized gases to produce three cooled streams, wherein the three different pressurized gases are the pressurized natural gas stream, the pressurized purge gas stream, and the pressurized air gas stream; and (c) liquefying the industrial gas in a liquefaction unit against the three cooled streams to produce a liquefied industrial gas stream. The industrial gas to be liquefied is selected from the group consisting of a first portion of the pressurized natural gas stream, a nitrogen gas stream, hydrogen and combinations thereof.

摘要： This invention presents improved combustion methods, systems, engines and apparatus utilizing H2, O2 and H2O as fuel, thereby providing environmentally friendly combustion products, as well as improved fuel and energy management methods, systems, engines and apparatus. The Water Combustion Technology; WCT, is based upon water (H2O) chemistry, more specifically H2O combustion chemistry and thermodynamics. WCT does not use any hydrocarbon fuel source, rather the WCT uses H2 preferably with O2 and secondarily with air. The WCT significantly improves the thermodynamics of combustion, thereby significantly improving the efficacy of combustion, utilizing the first and second laws of thermodynamics. The WCT preferably controls combustion temperature with H2O and secondarily with air in the combustion chamber. The WCT preferably recycles exhaust gases as fuel converted from water. The WCT minimizes external cooling loops and minimizes exhaust and/or exhaust energy, thereby maximizing available work and internal energy while minimizing enthalpy and entropy losses.

摘要： A product cryogenic liquid mixture comprising oxygen and nitrogen having a chosen mole fraction of oxygen is produced by expanding, typically through a valve, a pressurized stream of a precursor fluid mixture, which may be liquid air, having a mole fraction of oxygen greater than said chosen mole fraction, and thereby forming a vapor phase depleted of oxygen and a liquid phase enriched in oxygen. The vapor phase is disengaged from the liquid phase in a phase separator. A stream of the vapor phase is condensed in a condenser. The condensate is collected in a storage vessel as the product cryogenic liquid mixture.

摘要： Disclosed is a production process and apparatus of high-purity air and various air material gases for semiconductor production factories that, together with enabling the production of high-purity air, also enables the production high-purity nitrogen simultaneous to the production of oxygen-rich air as the finished product. This is accomplished by compressing feed air to a pressure of 3 to 10 kg/cm.sup.2 G, introducing this compressed air into a catalyst tower (8) to convert the carbon monoxide, hydrocarbons and hydrogen contained in the feed air into carbon dioxide and water, and introducing the purified air into an adsorption tower (12a) or (12b) after cooling the heated air following catalytic reaction to remove carbon dioxide, water and other minute amounts of impurities by adsorption. A portion of the resulting purified air is removed as product high-purity air, while the remainder is introduced into a main heat exchanger (18) where it is cooled to substantially the liquefaction temperature. After cooling, the air is introduced into a single rectification tower (19) followed by liquefaction rectification. High-purity nitrogen is then removed from the top of said single rectification tower which is then obtained as product high-purity nitrogen after going through the main heat exchanger (18). On the other hand, oxygen-rich liquefied air is drawn out from the bottom of the single rectification tower (19). This oxygen-rich liquefied air is then introduced into a condenser-evaporator. (24) where it is vaporized and then drawn out. This drawn out air is then introduced into the main heat exchanger (18) where it is heated to an intermediate temperature and then removed. This oxygen-rich air is then introduced into an expansion turbine (35) where it is expanded and lowered in temperature. After generation of cold, the cold is recovered followed by obtaining of the product gas in the form of purified oxygen-rich air.

摘要： The invention is a contaminant removal system for purifying air. Incoming air is cooled to a cryogenic temperature. A vortex tube further cools the cooled air so as to solidify contaminants therein. A filter system then filters out the solidified contaminants from the air.Use of a vortex tube minimizes the amount of moving parts. This reduces maintenance and concommitant costs involved with operation. The present system has a long life. The vortex tube is relatively inexpensive.

摘要： The invention relates to a method of separating from a gaseous medium vaporous substances having a low boiling point contained in high proportions in the medium, by subjecting said medium to a scrubber where said vaporous substances are precipitated as cold liquid condensates the coldness component of which is transferred to a circulating refrigerant. Provisions are made for different levels of coldness by utilizing cold-vapor and cold-air refrigeration units in which condensates and clean air produced by the system are used as refrigerants. Heat generated by a compressor in the cold-air refrigeration unit may additionally be used in a degassing unit used to remove non-condensible components from the condensate and/or refrigerant.

摘要： The present invention utilizes a turboexpander coupled with a compressor in place of the Joules-Thomson expansion valve in a conventional refrigeration to achieve higher efficiency. More specifically the refrigeration is used in removing condensable hydrocarbons or chemical vapors from air which has been contaminated during loading and unloading at bulk plants. The more efficient turboexpansion cycle allows the use of saturated lower aliphatic hydrocarbons, such as ethane as refrigerant, the use of which would be precluded from normal Joules-Thomson expansion cycles. The turboexpander work is used to drive a compressor which partially recompresses the expanded refrigerant gas, providing an essentially isentropic expansion. Because the turboexpander and the compressor operate on the same fluid, the mass flows through both are equal thereby alleviating control and loading problems.
