12.2 Coke Production US EPA

2015-9-10  12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

Coke Manufacturing IFC

Coke production facilities generate process solid wastes other than coke breeze (which aver-ages 1 kg/t of product). Most of the solid wastes contain hazardous components such as benzene and PAHs. Waste streams of concern include resi-dues from coal tar recovery (typically 0.1 kg/t of coke), the tar decanter (0.2 kg/t of coke), tar stor-

Coke Making Process

Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours. During that time, the volatiles of the coal are driven into the offgas and a pure carbon form called “coke” remains.

What Is Metallurgical Coke? Sciencing

Metallurgical coke sounds like a soda beverage, but it's not. It is a refined carbon product made from a special kind of coal. Using extremely high temperatures, coal can purified into coke -- which is then used in the iron and steel making processes. One of the most important steps in the coke-making process

Effect of preheating on coking coal and metallurgical coke

In the carbonization chamber, coking coal is slowly heated (at ~3 °C/min) to between 1000 and 1100 °C in the absence of air, producing coke by destructive distillation [,,,6,7]. In the coking process, the properties of coking coal, such as the CP and ash content, primarily control the coke quality [1,,, ].
