Commercial Liquid Calcium Hydroxide (Ca(OH)2) 상용 액상소석회
Principle 원리
CaCO3 → CaO + H2O → Ca(OH)2
Pros/Cons 장단점
  • Amount of CO2 emissions are significantly high depending on the heat treatment process. (Depending on decomposition of CaCO3 & fossil fuel usage)
    소성공정 (연료사용)에 따른 CO2 배출 심함. (CaCO3 분해에 따른 CO2 + 연료사용에 따른 CO2)
  • Complex process (Heat treatment → Grinding → Hydration)
    공정의 복잡성 (소성 → 분쇄 → 수화)
  • Particle size uncontrollable (Maximum 500mesh)
    입자크기 조절 어려움 (최대 500메쉬)
  • Pipe blockage occur
    배관막힘 현상
  • Low solubility of CaO → Low calcium concentration
    CaO의 낮은 용해도로 인해 칼슘의 농도가 낮음
  • Use more ingredients due to low chemical reaction → Chemical sludge
    반응성 저하로 인한 추가 투입 (슬러지 발생)
PMI Liquid Calcium Hydroxide (Ca(OH)2) PMI 액상소석회
Principle 원리
Ca2+ + 2Cl- → (replace Cl-to (OH)-) → Ca(OH)2
Pros/Cons 장단점
  • Minimize & recycle CO2 emissions through liquid process (CO2 zero)
    액상공정에 따른 CO2 배출 최소화 및 배출되는 CO2의 전량 재활용 (최종 배출 CO2 제로)
  • Simplified process (Dissolve → Reaction)
    공정의 단순화 (용해 → 반응)
  • Small particle size (1000mesh)
    입자크기 작음 (1000메쉬)
  • Pipe blockage X
    용액 내 흐름성이 좋아 배관막힘 없음
  • Liquid process → High calcium concentration
    용액공정으로 인해 칼슘의 농도가 높음
  • No additional ingredients needed due to high chemical reaction → Minimize chemical sludge
    반응성이 좋아 추가 투입 불필요 (슬러지 최소)
