Product Details
Coke oven gas is cooled, and by-products are recovered. Flushing
liquor, formed from the cooling of coke oven gas, and liquor from
primary coolers contain tar and are sent to a tar decanter. An
electrostatic precipitator is used to remove more tar from coke
oven gas. The tar is then sent to storage. Ammonia liquor is also
separated from the tar decanter and sent to wastewater treatment
after ammonia recovery. 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.
During the coke quenching, handling, and screening operation, coke
breeze is produced. It is either reused on site (e.g., in the
sinter plant) or sold off site as a by-product.
