First we acidify the Distillate with CO2 injection and then add Lime water for calcium hardness addition and we have a regulation to have a minimum of 50ppm calcium hardness.The lime saturators produce the Lime water from the Lime milk which is the solution of water and Hydrated Lime by continuous recirculation and also constant feeding of Lime milk and bleeding of Lime sludge.So there is no excess addition as the target is to meet 50ppm calcium hardness
