nh3 evacuation for Transformers

nh3 evacuation for Transformers

This is a process of hydrocracking of the bonds between carbon and heteroatom with nearly complete transformation of sulfur, nitrogen and oxygen containing organic compounds into saturated hydrocarbons with simultaneous formation of easily removable H2S, NH3 and water vapor; hydrogenation of unsaturated hydrocarbons.
