Many industrial factories generate flue gases that content sulfur dioxide and hydrogen chloride or Hydrochloric acid from flue gases. These elements are very harmful to the air, and causes air pollutions. In order to reduce low emission values, lime is use to purify these elements.
CAO Fine Ground High Calcium Lime and High Calcium Lump Lime are highly efficient in removing these harmful acidic gases through wet lime scrubbing and dry lime scrubbing methods.
Lime reacts with sulfur dioxide to form calcium sulfite. The sulfite can then be air oxidized to form calcium sulfate dehydrated or gypsum, which is suitable for recycling.
