The gas liquefaction system includes a gas delivery passageway, gas driving equipment and at least two pieces of gas liquefaction equipment that are arranged according to level. The gas driving equipment is configured to drive a gas to enter the gas liquefaction system from the gas inlet end. The gas liquefaction equipment is configured to liquefy the gas in the order of the levels. The gas liquefaction system further includes gasification equipment which is configured, when any arbitrary gas liquefaction equipment of the at least two pieces of gas liquefaction equipment is in need of cold energy for gas liquefaction, to exchange heat with the liquefied gas released from the liquefied gas storage tank that contains already liquefied gas and is associated with a gas liquefaction equipment which is at a level higher than or equal to the level of the arbitrary gas liquefaction equipment, thereby gasifying the liquefied gas released from the liquefied gas storage tank. The gas liquefaction system further includes a cold energy pipeline configured to deliver the cold energy generated by gasification to the arbitrary gas liquefaction equipment, so that the arbitrary gas liquefaction equipment receives the cold energy to exchange the heat generated during gas compression. In addition, the present invention also relates to a gas liquefaction method.

    摘要: Natural gas boiling off from LNG storage tanks located on board a sea-going vessel, is compressed in a plural stage compressor. At least part of the flow of compressed natural gas is sent to a liquefier operating on a Brayton cycle in order to be reliquefied. The temperature of the compressed natural gas from the final stage is reduced to below 0° by passage through a heat exchanger. The first compression stage is operated as a cold compressor and the resulting cold compressed natural gas is employed in the heat exchanger to effect the necessary cooling of the flow from the compression stage. Downstream of its passage through the heat exchanger the cold compressed natural gas flows through the remaining stages of the compressor. If desired, a part of the compressed natural gas may be supplied to the engines of the sea-going vessel as a fuel.

    摘要: A system and method for producing liquefied natural gas are provided. The method may include compressing a process stream containing natural gas in a compression assembly to produce a compressed process stream. The method may also include removing non-hydrocarbons from the compressed process stream in a separator, and cooling the compressed process stream with a cooling assembly to thereby produce a cooled, compressed process stream containing natural gas in a supercritical state. The method may further include expanding a first portion and a second portion of the natural gas from the cooled, compressed process stream in a first expansion element and a second expansion element to generate a first refrigeration stream and a second refrigeration stream, respectively. The method may further include cooling the natural gas in the cooled, compressed process stream to a supercritical state with the first and second refrigeration streams to thereby produce the liquefied natural gas.

The power plant comprises a first gas expansion unit connected to a generator. The air handling system comprises an air compression unit, a heat exchange system, and a fluid tank. In a first operating mode, feed air is compressed in the air compression unit and cooled in the heat exchange system against a first and a second coolant. A storage fluid is generated and stored as cryogenic fluid in the fluid tank. In a second operating mode, cryogenic fluid is removed from the fluid tank, vaporized, or pseudo-vaporized, at superatmospheric pressure, and heated in the heat exchange system against the second and first coolants.
