<P>PROBLEM TO BE SOLVED: To manufacture caustic soda, fresh water, common salt, hydrogen, chlorine, hydrochloric acid, magnesium, sodium and the like at a seawater collecting site by effectively using natural energy such as ocean current and wind power, and simultaneously manufacture new virgin aluminum from alumina, cryolite and fluorite shipped in a port. <P>SOLUTION: In the ocean electrolysis plant, fresh water is manufactured from seawater by a reverse osmosis process using electric power obtained from a wind turbine and a hydraulic turbine installed in a channel formed by a multi-hull vessel moored in current of Japan Current, irrigation water simultaneously discharged is concentrated to about 30% concentration by an ion-exchange membrane dialysis process, and caustic soda is manufactured by solution electrolysis of the same. Fresh water, common salt, hydrogen, chlorine, hydrochloric acid, magnesium, sodium and the like are simultaneously manufactured as by-product and are landed in a port of call, and new virgin aluminum is manufactured by fused-salt electrolysis of alumina, cryolite and fluorite shipped in return vessel by electric power obtained from fluid energy. <P>COPYRIGHT: (C)2008,JPO&INPIT |
