Improve coal quality and reduce emissions of coal-fired pollutants. Coal washing can remove 50%-80% of ash and 30%-40% of total sulfur (or 60%~80% of inorganic sulfur) in coal.

Coking Process

The major subforms of the coking process are (1) the delayed coking process and (2) the fluid coking process. To a large extent, most cokers are constructed of Type 410 stainless steel, either claded (i.e., bonded with another metal) or solid, except those with high naphthenic acid content, which would normally require Type 316.
