sulfur remuval plant from coal

Whether it is electricity, liquid fuels, or some other product being output, sulfur emissions are regulated, and sulfur removal is important for this reason, along with the prevention of downstream component fouling. In addition to these constraints, recovering saleable sulfur is an important economic benefit for a gasification plant.

High-sulfur coals, however, are now known to derive most of their sulfur from reduction of sulfate ions to H2S in sea or brackish water in the coal beds by microbial processes. The H2S is chemically incorporated into the peat during diagenesis.
