Coke Coal Hydraulic Beneficiation Process

2018-7-18  The basic purpose of beneficiation is to reduce the ash forming impurities from raw coal so that better coal with less ash content can be produced. If these ash forming constituents are not removed, and coal is directly charged to the coke-ovens, the ash content in coke will increase and subsequently more slag will be produced in the blast furnace thereby lowering the efficiency of the blast furnace.

Coking Coal an overview ScienceDirect Topics

Coke is produced by baking coal in the absence of oxygen to remove the volatile hydrocarbons contained in coal. The resulting coke is mechanically strong, porous, and chemically reactive, which are all critical properties for stable blast furnace operation.

Coke Manufacturing IFC

Coke oven gas is further cooled in a final cooler. Naphthalene is removed in the separator on the final cooler. Light oil is then removed from the coke oven gas and is fractionated to recover benzene, toluene, and xylene. Some facilities may include an onsite tar distillation unit. The Claus process is normally used to recover sulfur from coke oven gas.
