Process Description1,2 All metallurgical coke is produced using the "byproduct" method. Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. coke plants use the KopperBecker byproduct oven. These ovens must remain airtight under the cyclic stress of expansion and contraction.

Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. coke plants use the KopperBecker byproduct oven. These ovens must remain airtight under the cyclic stress of expansion and contraction. Each oven has 3 main parts: coking chambers, heating chambers, and regenerative chambers.

Generally, the term 'destructive distillation' is used to refer to the processing of certain organic materials along with limited amounts of oxygen and certain reagents, solvents, or catalysts such as phenols and steam. It can also be used to denote the processing of organic material in an environment void of air (pyrolysis in the absence of air).
