Ammonium sulfate | (NH4)2SO4

In the direct process the unpurified coke-oven gas is introduced into sulfuric acid to yield ammonium sulfate contaminated by colored tar products. In the indirect process the ammonia is washed out of the coke-oven gas with water, released with a lime suspension, and finally introduced into sulfuric acid.
