Product Details
Coke and coke by-products, including coke oven gas, are produced by
the pyrolysis (heating in the absence of air) of suitable grades of
coal. The process also includes the processing of coke oven gas to
remove tar, ammonia (usually recovered as ammonium sulfate),
phenol, naphthalene, light oil, and sulfur before the gas is used
as fuel for heating the ovens. This document covers the production
of metallurgical coke and the associated by-products using
intermittent horizontal retorts. In the coke-making process,
bituminous coal is fed (usually after processing operations to
control the size and quality of the feed) into a series of ovens,
which are sealed and heated at high temperatures in the absence of
oxygen, typically in cycles lasting several hours. Volatile
compounds that are driven off the coal are collected and processed
to recover combustible gases and other by-products. The solid
carbon remaining in the oven is coke.
