Abstract
(EN)
A desalination system capable of producing hydrogen according to an embodiment of the present invention comprises: a desalination process unit in which inlet water is prepared into produced water and concentrated water by water treatment through a reverse osmosis process; and a chlorine-alkali process unit having an inner space demarcated into an anode part and a cathode part, the concentrated water being supplied into the anode part, and the produced water being supplied into the cathode part, wherein the chlorine-alkali process unit, through the use of solar electric energy, preferably generates chlorine gas from a salt of the concentrated water through a chemical reaction in the anode part by using the concentrated water as an electrolyte and generates hydrogen gas and sodium hydroxide through a chemical reaction in the cathode part by using the produced water as an electrolyte.

본 발명의 일 실시예에 따른 수소 생산가능한 담수시스템은, 유입수가 역삼투 공정을 통해 생산수와 농축수로 수처리되는 담수화공정부; 및 농축수가 공급되는 양극부와, 생산수가 공급되는 음극부로 내부공간이 구획된 염소-알칼리공정부를 포함하되, 염소-알칼리공정부는 태양광 전기에너지를 이용하여, 농축수를 전해질로 양극부에서의 화학반응을 통해 농축수의 염으로부터 염소기체를 발생시키고, 생산수를 전해질로 음극부에서의 화학반응을 통해 수소기체와 수산화나트륨을 발생시키는 것이 바람직하다.
