Abstract

A new apparatus for seawater desalination, based on the principle of gas hydrates, is suggested. The equipment continuously produces and pelletizes gas hydrates by a squeezing operation in a dual cylinder unit, which is able to extract pure hydrate pellets from the seawater-containing reactor. Desalination efficiency for each dissolved ion from seawater samples was tested by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and ion chromatography (IC) analysis. This study demonstrates that the suggested method and the stated apparatus may solve the difficulty of separating hydrate crystals from concentrated brine solutions, and therefore may be applied to improve the efficiency of existing desalination processes.

가스하이드레이트 원리를 이용한 신개념의 해수담수화 장치를 제안하였다. 본 연구의 연속식 장치는 하이드레이트를 제조하고, 듀얼실린더의 압축공정에 의해 해수로부터 순수의 하이드레이트 펠릿화가 가능하다. 해수 샘플로부터 용존된 각 이온들의 제거 효율이 유도결합플라즈마분광광도계(ICP-AES)와 이온크로마토그래피(IC)에 의해 분석되었다. 본 연구에서 제안된 방법과 장치를 이용한 해수담수화시 형성된 하이드레이트 결정과 고농도의 염농축액과의 분리에 어려움이 있지만, 이를 해결함으로 좀더 효율적인 해수담수화 공정 적용이 가능할 것으로 판단된다.
