박인기 (단국대학교 에너지공학과) , 이창현 (단국대학교 에너지공학과)
Chlor-alkali (CA) membrane process is based on salined water electrolysis employing cation condutive polymer electrolytes, which has been used for the conventional production of both sodium hydroxide and chlorine gas. The CA membrane process has advantages such as relatively low environmental impact...

멤브레인법에 기반한 이온전도성 고분자전해질막의 기본 요건은? | ∙ 높은 이온전도도(예 : Na+ ion conductivity) ∙ 강염기(예 : > 32 wt% NaOH)와 강산(예 : Cl2 및 HCl)에 대한 우수한 내화학성 ∙ 염소 및 수소가스에 대한 배리어성 ∙ 높은 전기화학적 안정성 ∙ 높은 내열성(~60-90°C) ∙ 우수한 가공성 ∙ 저렴한 생산단가 | |
클로알칼리(CA) 멤브레인법이란 무엇인가? | 클로알칼리(CA) 멤브레인법은 이온전도성 고분자전해질을 이용한 염수전기분해공정을 의미하며, 전통적으로는 가성소다와 염소 생산을 목적으로 하고 있다. CA 멤브레인법은 기존 클로알칼리 공정으로 사용되어왔던 수은법 및 격막법에 비해 환경적 유해성이 낮으며, 에너지비용을 상당히 감소시킬 수 있다는 장점을 나타낸다. | |
