| (54) | NOVEL FUEL PRODUCTION PLANT AND SEAWATER DESALINATION SYSTEM FOR USE THEREIN |
| (57) A novel fuel production plant and a seawater desalination system for use therein
in which a water production system using an evaporation method can be applied at a
seawater intake amount comparable to that required in system using a reverse osmosis
membrane method, the degree of freedom in selecting the plant installation site is
high, salinity of produced water is reduced as compared with that in the case using
the reverse osmosis membrane method, and the merit of the evaporation water production
system having a low maintenance cost can be enjoyed. A novel fuel producing section
(100) produces synthesized gas from a feedstock and synthesizes novel fuel from the
synthesized gas thus produced, and has exhaust heat recovery boilers (5, 8) for generating
steam by recovering excess heat generated from the synthesizing processes. An exhaust
heat utilizing section (200) includes steam turbines (9, 12, 17, 18, 21) driven with
the steam generated from the exhaust heat recovery boilers (5, 8). An open circulation
cooling water supply section (300) supplies cooling water for a plant, including water
for cooling exhausts of the steam turbines, and includes a seawater desalination system
(38, 39) 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 38, 39.
