MIDDLE DISTILLATE PRODUCTION METHOD AND SYSTEM FOR USING LNG

摘要

The present invention relates to a method and a system for producing intermediate crude oil using liquefied natural gas (LNG) capable of producing fuel for transport (diesel oil) by using LNG even in an area without a gas field. The method and system comprise a LNG re-gasfication unit (12) receiving LNG and producing evaporated gas; a GTL processing unit (13) producing syngas using the natural gas processed in the LNG re-gasfication unit (12) and synthesizing intermediate crude oil and wax using the syngas; and a reforming unit (14) purifying the intermediate crude oil and wax synthesized in the GTL process unit (13) into a final product diesel oil and separating the gases (H_2, CO) necessary for synthesis from the gases (CO_2) unnecessary for synthesis among gases unreacted in the GTL process unit (13), thereby reducing an installation area and the capacity of a freezer and increasing the production of electricity.
