Method for manufacturing regenerated gypsum using waste citric acid and regenerated gypsum manufactured by the method
In a method recycled gypsum manufacturing method using a citric acid waste solution, impurities in the citric acid waste solution are removed using a filter, and by distilling the citric acid waste solution from which the impurities have been removed, acetic acid (CH_3COOH) and nitric acid (HNO_3) are extracted from the citric acid waste solution and separated to manufacture a citric acid solution, and recycled gypsum can be manufactured in an environmentally friendly manner by mixing desulfurized gypsum and water with the citric acid solution desulfurized in the way.
구연산폐액을 이용한 재생석고 제조 방법에 있어서, 필터를 사용하여 구연산폐액 속 불순물을 제거하고, 불순물이 제거된 구연산폐액을 증류함으로써 구연산폐액에서 초산(CH3COOH) 및 질산(HNO3)을 분리하여 구연산액을 제조하고, 이와 같이 제조된 구연산액에 탈황석고 및 물을 혼합함으로써 친환경적으로 재생석고를 제조할 수 있다.
