    摘要: Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods and gas field development methods are provided. Gas is compressed hydraulically by seawater introduced into vessels and separated from the gas by a water immiscible liquid layer. Tall, possibly vertical helical vessels are used to reach a high compression ratio that lowers the liquefaction temperature. Cooling units are used to liquefy the compressed gas, possibly by a coolant which is itself pressurized by a similar mechanism. The coolant may be selected to be liquefied under surrounding seawater temperatures. The seawater which is used to pressurize the gas may be used after evacuation from the vessels to pressurize intrastratal gas in the production stages and broaden the gas field development.

    摘要: A method and system for the small-scale production of LNG. The method comprising: configuring a prime mover to be operable communication with a multi-stage compressor; configuring the prime mover to be in fluid communication with an ammonia absorption chiller; configuring the ammonia absorption chiller to be in fluid communication with the multi-stage compressor; operating the ammonia absorption chiller using waste heat from a prime mover; pre-cooling a first stream of natural gas using cooled fluid from the ammonia absorption chiller; cooling a first portion of the first stream of natural gas, using an expansion valve, into a two-phase stream; cooling a second portion of the first stream to liquefied natural gas, using the two-phase stream as a cooling fluid; delivering the second portion of the first stream as LNG to a low-pressure LNG tank; cooling a third portion of the first stream of natural gas in a turbo-expander; separating liquid heavies out of the third portion of the first stream of natural gas; and delivering the liquid heavies to a pressure tank.

    摘要: The apparatus for conveying and compressing a gaseous medium utilizes thermoacoustic oscillations. The oscillations are generated in a tubular cavity by means of a heat source or heat sink with the medium to be conveyed being taken in through a check valve on one side while being exhausted after compression through a second check valve on an opposite side. During operation, the heat is supplied to the medium within the tubular cavity to generate thermoacoustic oscillations.In one embodiment, a plurality of tubes can be disposed in series relative to a common line. Also, the apparatus can be used in combination with a helium liquifying plant.
