    Abstract: The present invention relates to a gas liquefaction system to achieve the purpose of conveniently providing cold energy to liquefy a gas. 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.

    Abstract: A process for liquefying a gaseous methane-rich feed (20) to obtain liquefied natural gas, wherein a gaseous methane-rich feed at elevated pressure is conducted through a heat exchanger (1), where it is cooled, liquefied and sub-cooled against evaporating refrigerant. The liquefied product (21) is discharged from the heat exchanger. The refrigerant cycles in a closed loop, wherein the evaporated refrigerant (22) is removed from the heat exchanger, and is compressed (30) to get high pressure refrigerant which is cooled (31,32) and divided into a liquid (heavy) portion (24) and a gaseous (light) portion (25), which are conducted to the heat exchanger for sub-cooling and liquefying the gaseous methane-rich feed. The sub-cooled refrigerant portions are introduced (35,37) into the shell of the heat exchanger at respective positions for being evaporated. The process is controlled by two separate process controllers, wherein the mass flow of the methane-rich feed is controlled by using a first process controller, and the loop of the refrigerant is controlled by a second controller using a model predictive control.

    Abstract: Disclosed are methods for efficiently and economically designing, constructing, or operating a light hydrocarbon gas liquefaction process for the liquefaction of selected quantities of light hydrocarbon gas. The method includes a light hydrocarbon gas liquefaction launch train to liquefy an initial amount of light hydrocarbon gas and one or more optional subsequent modular expansion phases to said light hydrocarbon gas liquefaction train to liquefy additional selected quantities of light hydrocarbon gas up to a selected maximum quantity of light hydrocarbon gas for the process. The methods employ shared use facilities, such as light hydrocarbon feed gas pretreatment facilities, refrigerant compression facilities, cryogenic heat exchange facilities, access services, other liquefaction equipment, and liquefied product storage and shipping facilities. The use of such shared use facilities allows for subsequent expansion phases or modules to be constructed to increase overall plant capacity, which can reduce the capital costs and space needed relative to prior methods for the design, construction, or operation of a light hydrocarbon liquefaction process which call for construction of a complete liquefaction train and all of its associated components and related equipment.
