Novel fuel production plant and seawater desalination system for use therein

Abstract

A novel fuel producing section produces synthesized gas from a feedstock and synthesizes novel fuel from the synthesized gas thus produced, and has exhaust heat recovery boilers for generating steam by recovering excess heat generated from the synthesizing processes. An exhaust heat utilizing section includes steam turbines driven with the steam generated from the exhaust heat recovery boilers. An open circulation cooling water supply section supplies cooling water for a plant, including water for cooling exhausts of the steam turbines, and includes a seawater desalination system for desalinating seawater by the evaporation method and supplying desalinated water to replenish the cooling water. The cooling water supplied from the open circulation cooling water supply section is used in condensing of the desalinated water produced by the seawater desalination system.

Description

TECHNICAL FIELD [0001] The present invention relates to a novel fuel production plant for producing novel fuel, and to a seawater desalination system for use in the plant. BACKGROUND ART [0002] Recently, attention has been focused on plants for producing novel fuel, such as Gas-To-Liquid (GTL) and dimethylether (DME). As a novel fuel production plant, one known example for producing dimethylether by using natural gas as a feedstock is disclosed in, e.g., JP,A 10-195008. DISCLOSURE OF THE INVENTION [0003] In plants for producing novel fuel, such as GTL and DME, (hereinafter referred to as “novel fuel production plants” or simply as “plants”), for example, a partial oxidation method or an auto-thermal reforming method using hydrocarbons, etc. as a feedstock is employed to produce synthesized gas necessary for synthesizing fuel. In those synthesized gas producing methods, the temperature of the synthesized gas at an outlet of a reaction / reforming furnace is very high (1200-1500° C.). O...
