Air Pollutant & Gases Treatment

UNICARB TCH200 is Technical Grade Calcium Hydroxide, usually named Hydrated Lime or Slaked Lime, Hydrated Lime UNICARB TCH200 is manufactured and tested according to AS1672/1997 with Available Lime Index as Calcium Hydroxide more than 90%, as Calcium Oxide more than 70% and pH > 12. Hydrated Lime UNICARB TCH200 plays a significant role in the removal of pollutants from the flue-gas streams of coal-fired power plants, incinerators and industrial facilities. Hydrated Lime UNICARB TCH200 are used in the treatment of pollutants such as sulfur dioxide (SO2), hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur trioxide (SO3), Arsenic (As), Selenium (Se), fine particulates and mercury (Hg).

In wet FDG processes, these products are slurried with water and sprayed into a flue-gas scrubber vessel. The acidic gases, normally SO2 and HCl, are absorbed into the water where they chemically react with the lime and limestone. The resulting products, primarily calcium sulfite, can then be oxidized to produce calcium sulfate, a salable gypsum byproduct
