해양그린수소플랜트용 해수담수-농축 복합공정 개발

Abstract

Reverse osmosis (RO) process, a major technology for seawater desalination, significantly increases energy consumption (kWh/m3) as the concentration of influent increases, and is economical due to complex pretreatment processes such as chemical cleaning to minimize membrane contamination. , has environmental problems. On the other hand, adsorption desalination (AD) technology can simultaneously produce concentrated and fresh water at high concentrations using a low temperature (< 80°C) heat source, and operates at low temperature (< 30°C) and low pressure (< 10 kPa). Therefore, it is possible to minimize the occurrence of fouling and scale compared to the existing seawater desalination technologies (MED, MSF, RO), and accordingly, it is an environment-friendly that can minimize the use of chemicals in the pretreatment process. seawater desalination technology. In this study, As a disadvantage of the existing AD process, a 3-bed process was applied to develop an adsorption-based composite process, and the freshwater production and performance ratio of the existing 2-bed process and the developed 3-bed process were analyzed and verified.
