摘要： Nitrogen is produced above an offshore hydrocarbon reservoir (12) and injected into the reservoir, by a complex (40) mounted on a previously used vessel hull (16). The vessel weathervanes and the complex includes equipment that takes in ordinary air from a bow end (32) of the vessel, cools the air using sea water pumped into the equipment, and liquefies the oxygen component of air so pure nitrogen remains. The complex also includes injection equipment that heats and pressurizes the pure nitrogen to inject it into the reservoir. The complex is mounted above pipes (24) on the deck (22) of the vessel hull, on spacers (62) so mounting of equipment can be accomplished rapidly and without major alterations to the hull. A riser bundle (150) that extends from the hull to the sea floor, may include both a production riser (152) that carries crude hydrocarbons up to the vessel for storage in hull tanks (20), and an injection riser (160) that carries pressured nitrogen. The lower end of one of the risers is connected to a sea floor pipeline (162) that extends at least 100 meters away from the lower end of the other riser.

摘要： The present invention is an improvement to a process for the production of work to generate electricity or to drive a mechanical device using a gas turbine. In the process, feed air stream is compressed and combusted with a fuel gas to produce a combustion product. This combustion product is expanded in a gas turbine expander, thereby producing a hot exhaust gas and work. This produced work is used to generate electricity or to drive a mechanical device. The improvement to the process, which increases the work produced by the gas turbine expander, is characterized by cooling nitrogen product, produced by a cryogenic air separation unit to a subambient temperature and combining this subambient cooled, nitrogen product with the feed air stream prior to compression. The improvement of the present invention is particularly suited to the process, wherein at least a portion of the oxygen product produced by the cryogenic air separation unit is reacted with a carbonaceous feedstock in a gasification unit to produce the fuel gas, which is rich in carbon monoxide and hydrogen. The carbonaceous feedstock reacted in the gasifier unit can be coal, petroleum coke, tar sands bitumen, tar sand emulsion, municipal wastes, petroleum residua, waste oil or mixtures thereof.

摘要： A fluid material is cooled through a temperature range exceeding 200.degree. F. by heat exchange with a single mixed refrigerant composition in a heat exchange zone forming a part of a closed loop refrigeration cycle thus assuring high reliability and low investment by virtue of simplification of the equipment required and ease of control thereof. The process is especially useful for liquefaction of natural gas. Refrigerant in the refrigeration loop containing constituents having increasingly lower boiling points is successively directed from a compression zone to a condensation zone, thence to a heat exchange zone, next expanded in an expansion zone, returned to the heat exchange zone for countercurrent flow against the refrigerant flowing therethrough from the condensation zone to the expansion zone, and finally returned to the compression zone. The natural gas is directed to the heat exchange zone and liquefied therein by countercurrent flow against the cold refrigerant stream flowing from the expansion zone to the compression zone. The refrigerant is made up of C.sub.1 to C.sub.5 hydrocarbons plus nitrogen as an optional constituent with the relative proportions of the constituents being controlled so that the combined cooling curve of the hot refrigerant stream and the feed gas closely matches the heating curve of the cold refrigerant stream in a sense that the curves are in close proximity at the lowest temperature levels thereof and relatively uniformly and slowly diverge as the highest temperature points on the curves are approached.
