摘要

A process to re-gasify a liquefied and methane-rich hydrocarbon gas mixture, whereby a product is obtained at pressures and temperatures suitable for distribution by pipeline or pipeline, comprising the following operations: pressurizing a gas stream liquefied natural gas, dividing said stream of liquefied natural gas into three secondary streams, passing a first secondary stream to the top of a methane separator, passing a second secondary stream through a heat exchange system, thereby said second secondary current provides a cooling work to said heat exchange system, and is therefore heated, to recombine the third secondary current with a first portion of the second heated secondary stream, to use this recombined current to provide the work of cooling for several streams of the procedure in a separation n fractionated by distillation and condensation of the hydrocarbons present in said stream of liquefied natural gas, combining said recombined stream with the previously non-combined portion of said second secondary stream and introducing this lately combined stream into the middle zone of said methane separator, the vapors of the upper part of said methane separator, and passing said vapors in heat exchange relation with other streams of the process, whereby said vapors are heated to a suitable temperature for distribution by gas pipelines or pipes.
