摘要： 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.

摘要： Disclosed is a process for liquefying natural gas wherein an available methane-rich feed, i.e., natural gas, at an excess pressure is initially expanded to provide expansion work which may be utilized in a number of novel ways, such as to provide refrigeration in a refrigerant cycle used to cool the feed or in one or more refrigerant cycles used in a liquefaction zone to liquefy the feed, or to generate electrical power for use in the liquefaction process or for export. In one embodiment, the expansion work is obtained by use of an expander/compressor device (turboexpander) which expands the feed to (1) drive the compressor of the device and thereby provide compression for a closed loop propane refrigeration cycle to pre-cool the natural gas stream, and (2) produce an expanded, chilled natural gas feed for a liquefaction process. The production of a chilled natural gas feed to a liquefaction process can either increase the volume of LNG production for a given amount of installed horsepower, or alternatively, can be used to reduce the capital cost and/or operating cost associated with the production of a given amount of LNG.
