Abstract: A method is disclosed for the utilization of energy in gas of low heating value discharged from a production well of an in-situ combustion process for the production of oil. The low heating value gas is mixed with an amount of air that will provide oxygen in an amount that will limit the maximum temperature rise in a catalytic combustion chamber to avoid excessive temperatures regardless of changes in composition of the low heating value gas. The mixture is preheated and delivered into the catalytic combustion chamber at a temperature exceeding about 400.degree. F. that will cause ignition of the combustibles on contact with the catalyst. In a preferred embodiment, combustion is accomplished in two combustion chambers connected in series with a heat exchanger between the combustion chambers for cooling the combustion products discharged from the first combustion chamber before they are delivered to the next combustion chamber.

The turbine system is particularly advantageous in recovering power from low heating value gas in which the combustibles are hydrocarbons, primarily methane.

Abstract: A method of obtaining energy in useful form utilizing complex geothermal waters as a source of energy, the method comprising the steps of initially maintaining pressure on the hot geothermal waters to prevent vaporization, directly contacting the hot waters with at least one immiscible working fluid to effect a transfer of the heat energy from the geothermal waters to the working fluid. The heat transfer contact is preferably made in a multiple stage counter-current contact centrifuge, mixer-settlers, or a column. Solid phase heat transfer between the water and fluid may alternatively be employed such as by the use of heat pipes. The heated working fluid is thereafter separated from the geothermal waters, subjected to multiple stage vaporization and the resulting vapors are channeled to a turbine or similar working device to produce electricity. The spent working vapors are cooled and/or condensed to be recycled within the system.

The motor drives fluid compressors and further heat exchanging means communicate with the compressors and tank water to transfer heat of compression into the water to further enhance the temperature differential upon which motor operation depends.

Abstract: An apparatus and method for cooling internal environment air using energy from the sun. In accordance with the method of the invention, internal environment ("inside") air is circulated over a desiccant and thereby dried. The dried air, which takes on heat as a consequence of the drying operation, is relatively cooled by performing a heat exchange operation with external environment ("outside") air. At this stage, the dried inside air is at a temperature which is only slightly above the temperature of the outside air. Moisture is then added to the dried inside air which had been subjected to the heat exchange operation. The evaporation of the moisture into the dried air restores it to a desired relative humidity and effects a cooling of the air which is then returned to the internal environment. The operation of drying the inside air will, after a time, render the desiccant too wet to perform efficiently.

Abstract: In a liquefied gas supply system, a pressure switch senses pressure in the low-pressure supplied line of the system and opens a bypass valve to thereby bleed gas from the relatively warm reserve side and keep up the pressure in the supplied line while allowing the relatively cold service side to continue to contribute to the feed to the supplied line, but at the same time a flow limiting orifice limits cooling and controls temperature at the relatively cold service side by inhibiting the rate of absorption of heat-of-vaporization at the service side.
