phase change from liquid to gas at a temperature at or below the temperature of adsorption to an adsorbing reactor in heat exchange exposure to the adsorbent utilizing vaporized heat transfer fluid for driving the liquid heat transfer fluid in the cooling loop. The refrigerant may be used as the heat transfer fluid. The invention includes apparatus for carrying out the method.
METHOD AND APPARATUS FOR LIQUEFACTION OF NATURAL GAS
5479783 ABSORPTION
Low William Bartlesville, OK, UNITED STATES assigned to Phillips Petroleum Company A process and apparatus for liquefying a natural gas, having a pressure above about 800 psig, in which the natural gas is introduced into an expander which operates to reduce the pressure of the natural gas and extract work from the expansion of the natural gas during the pressure reduction so that the resulting effluent from the expander can be cooled to sequentially lower temperatures by passing the gas through a plurality of cooling stages, in indirect heat exchange with at least one refrigerant, until the gas is substantially completely condensed in the last of the cooling stages.
5477706 HEAT TRANSFER APPARATUS AND METHODS FOR SOLID-VAPOR SORPTION SYSTEMS Kirol Lance D; Rockenfeller Uwe Boulder City, NV, UNITED STATES assigned to Rocky Research In a sorption reaction system comprising one or more first reactors in which a refrigerant is alternately adsorbed and desorbed, and one or more second reactors in which a refrigerant is alternately desorbed and adsorbed, respectively, and having a cooling loop for directing heat transfer fluid to and from said reactors, a method of cooling an adsorbing reactor comprises directing liquid phase heat transfer fluid having a
