Abstract

본 발명은 타우린 제조 부산물을 물 및 메탄올에서 선택된 용제에 용해시키고 산, 예를 들어, 염산, 인산, 황산, 질산, 초산, 개미산에서 선택된 무기산 또는 유기산을 가하여 산성화시켜 생성되는 아황산가스를 가서소다 용액에 흡수시켜서, 아황산가스를 회수하고 잔류액에 기체를 주압시켜서 공기, 과산화수소, 오존과 같은 폭기제를 사용하여 폭기한 후 잔존 아황산가스를 구축하여 농축하고 침전되는 망초를 여과하고 건조시켜서 망초를 회수하여 정제하는 방법에 관한 것이다.The present invention dissolves sulphite gas produced by dissolving taurine byproducts in a solvent selected from water and methanol and acidifying them by adding an acid, for example, an inorganic or organic acid selected from hydrochloric acid, phosphoric acid, sulfuric acid, nitric acid, acetic acid, and formic acid. Absorb sulfur dioxide, recover the sulfurous acid gas, and pressurize the gas to the residual liquid, and then aeration with an aeration agent such as air, hydrogen peroxide, and ozone, then build up the remaining sulfurous acid gas, concentrate and filter the precipitated sediment and dry it to recover the forage It relates to a method for purification.
