Claims (6)

  1. 일정량의 세척액 부분 흐름을 일정한 농도를 가지며 일정한 용적량으로 공급되는 알칼리 용액흐름과 혼합시키고, 결과 혼할물의 pH 값을 연속적으로 측정하고, 혼합물의 pH 값을 위해 5 내지 9범위의 설정점이 선택되고, 중성 또는 알칼리 보정액이 측정된 pH 값의 상기 설정점 이하로의 감소에 반응하여 세척액에 첨가됨을 특징으로하는, 기체로부터 산성분을 제거하기 위한 세척구역에서 pH 값 3이하로 사용되고 적어도 부분적으로 순환되는 산 세척액의 pH 값을 조절하는 방법.
  2. 제1항에 있어서, 세척액은 주로 물로 구성됨을 특징으로 하는 방법.
  3. 제1항 또는 제2항에 있어서, 세척구역으로부터 퇴출된 세척액의 pH값이 2를 초과하지 않음을 특징으로 하는방법.
  4. 제1항 또는 제2항 내지 3항 중 한 항에 있어서, 보정액이 물로 구성됨을 특징으로 하는 방법.
  5. 제1항또는 제2항 내지 4항중 어느 한 항에 있어서, 세척액의 염함량을 측정하고 과도하게 높은 염함량인 경우에 세척액의 일부가 순환으로부터 제거되고 물로 대체됨을 특징으로 하는 방법.
  6. 제1항 또는 제2항 내지 5항중 어느 한 항에 있어서, pH 값을 측정하기 위한 수단으로부터의 액체 혼합물이 세척액에 공급됨을 특징으로 하는 방법,
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
