Steelmaking: The Coke Oven By-Product Plant

The coke oven by-product plant is an integral part of the by-product cokemaking process. In the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke

sulfide, ammonia, and nitrogen. Liquid products include water, tar, and crude light oil. The coking process produces approximately 338,000 L of coke oven gas (COG) per megagram of coal charged (10,800 standard cubic feet of COG per ton). During the coking cycle, volatile matter driven from the coal mass passes upward through cast

DELAYED COKING PROCESS. Description: Delayed coking process is a thermal process which increases the molecular aggregation or association in petroleum-based residues or coal tar pitches leading to extended mesophase domains. This is achieved by holding them at an elevated temperature (usually 750 K–765 K) over a period of time (12 to 36 h).
