Abstract

Mud, iron oxide, plaster, salt, minerals, and dissolved metals are sequentially deposited in accordance with the increasing concentration of seawater. In this paper, by using the physical characteristics of the seawater, we propose a new vacuum heat-transfer technology to subsequently obtain the proportion of the dissolved components in a cost-effective manner. Based on the vacuum heat-transfer characteristics of seawater, we comprehensively divide the seawater resource processes into the following four processes: (1) the salt concentration process to the saturation concentration, (2) crystallization process for salt formation, (3) mineral precipitation, and (4) remaining of dissolved metals.

바닷물을 농축하면 농도가 높아짐에 따라서 뻘과 산화철, 석고, 소금, 미네랄, 용존광물이 순차적으로 석출된다. 이 논문에서는 이러한 해수의 물리적 특성을 이용하여, 해수 중의 용존성분들을 순차적으로 석출하여 회수할 수 있는 경제성 있는 새로운 진공열전달기술을 제안하였다. 진공상태하의 열전달특성에 관한 실험적 결과를 토대로 해수 종합자원화를 위한 공정을 다음과 같이 4-공정으로 구분하였다. 즉, (1)소금이 석출되기 시작하는 포화농도까지의 농축하는 단계, (2)소금의 결정화가 이루어지는 단계, (3)미네랄이 석출되는 단계, (4)잔류 용존금속 액체의 4-공정이다.
