Thus, before being used as an energy source, COG must be purified. One of the stages of this treatment is chemical absorption, which removes ammonia from the gas. In addition to ammonia, the absorption system is also responsible for removing part of the H 2 S present in the COG. H 2 S is formed due to the presence of sulfur in the coal.
