Experience at NSL Chemical

  1. 1. EXPERIENCE WITH NSL CHEMICALS
  2. 2. 1 INTRODUCTION
  3. 3. FOUNDED IN
  4. 4. PRODUCTS Calcium Hydroxide Steel Slag Monolithic Refractories materials
  5. 5. PRODUCTION PROCESS Finer CaO Products SUPPLY/FEED AIR STORAGE HYDRATOR SEPARATOR LIME Coarser STORAGE Products AIR BALL SEPARATOR MILL
  6. 6. PRODUCTION PROCESS Limestone to quicklime: -Calcium carbonate ---heat---> calcium oxide (QUICKLIME) + carbon dioxide -Chemical formula: CaCO3 ---heat---> CaO + CO2 Quicklime to slaked lime: -Calcium oxide (QUICKLIME) + water ---> calcium hydroxide (SLAKED LIME) -Chemical formula: CaO + H20 ---> Ca(OH)2
  7. 7. PRODUCTION PROCESS CaC2(s) + 2 H2O(l C2H2(g) + Ca(OH)2(s) Calcium Carbide reacts with water to form acetylene gas and Calcium hydroxide (slurry).
