Coal Chemical Plant(CCP):

The volatile matter of coal liberated during carbonization is collected in gas collecting pipes in the form of raw coke oven gas passing through stand pipes. This is done by direct contact cooling with ammonia liquor spray. The gas cooled from 800^oC to 80^oC is drawn to Coal Chemical Plant by Exhauster. Coal Chemical Plant recovers Ammonia (NH₃), Tar and Benzol from CO-Gas. The primary By-products from Crude CO Gas are Ammonium Sulphate (NH₄)₂SO₄, Crude Tar, Crude Benzol and cleaned coke oven gas.
