- 원액을 농축액과 열교환하여 예열한 후, 전단에 가열기를 후단에 증기이젝터를 부설하고, 이 증기이젝터의 토출증기를 이 가열기의 가열원으로서 사용하도록 구성한 진공탈가스관으로 인도하고 전량의 1.0∼3.0중량%를 증발시키고, 이어서 증발장치로 이송하여 소정의 농도를 농축하는 동시에, 다시 그 증발증기를 알칼리 세정기로 도입하여 이 증발증기의 포화온도와 거의 같은 온도의 알칼리성 세정액으로 세정한 후, 기계식 압축기로 압축, 승온하고 상기 증발장치의 가열원으로서 사용하는 것을 특징으로 하는 레이온 스프 방사욕산 및 제철공장등 산세(피크링산)폐액 및 각종 폐산의 기계압축식 증발 농축방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
