"Methods to operate and to design efficient and econu00c8mica a process gas liquefaction of light hydrocarbons for liquefaction of hydrocarbon gas selected quantities of lightS ".Methods are disclosed for projecting.To build or operate efficiently and economically a gas liquefaction process for the liquefaction of light hydrocarbon gas selected quantities of light hydrocarbons.The method includes a train of release of gas liquefaction of light hydrocarbons (15) to liquefy an initial quantity of gas of light hydrocarbons (59) and one or more stages of expansion MoDular subsequ00b3entes optional (115, 215) to said gas liquefaction train of light hydrocarbons to liquefy additional gas selected quantities of light hydrocarbons (159259) up to a maximum amount of light hydrocarbons selected gas to the process.The train to launch includes facilities, such as facilities of pretreatment of feed gas of light hydrocarbons, facilities for compression of refrigerant.Cryogenic heat exchange facilities, access services, other equipment, liquefaction and storage facilities and transport of liquefied product.At least a portion of such facilities is employed as the premises of shared use.The use of such facilities shared allows expansion subsequ00b3entes phases or modules are constructed to increase the overall capacity of the plant,These modules can be built to increase the overall capacity of the plant, which can reduce the cost of capital and the space required in relation to previous methods for the project.The construction or operation of a process of liquefaction of light hydrocarbons require the construction of a train full of liquefaction and all of its components and associated equipment relacionadThe.
