Manufacture of coke oven products

isic code 191, 'Manufacture of coke oven products', represents a critical industry within the broader energy and manufacturing sectors. Coke, a solid fuel derived from coal, is a key input for various industrial processes, particularly in the production of steel. The manufacture of coke oven products plays a vital role in supporting the operations of 241 Manufacture of basic metals and other energy-intensive industries, making it an essential component of the global economy.

The production of coke oven products involves the heating of coal in the absence of oxygen, a process known as pyrolysis. Coal is loaded into coke ovens, where it is subjected to high temperatures, typically between 1,000 and 1,200 degrees Celsius. This intense heat drives off the volatile components of the coal, leaving behind a porous, carbon-rich material known as coke. The coke is then quenched, crushed, and sorted for various applications.

The primary input for the manufacture of coke oven products is coal, specifically bituminous coal or other types of coal with high carbon content. In addition to the raw material, the industry requires specialized coke ovens, which are designed to withstand the high temperatures and pressures involved in the pyrolysis process. Other important inputs include energy sources, such as electricity or natural gas, to power the ovens, as well as water for the quenching and cooling of the coke.

The primary output of the coke oven industry is coke, which is used as a fuel and reducing agent in the production of 241 Manufacture of basic metals, particularly in the manufacture of iron and steel. Coke oven products may also include other by-products, such as coal tar and coal gas, which can be further processed and utilized in various industries, including 201 Manufacture of basic chemicals, fertilizers and nitrogen compounds, plastics and synthetic rubber in primary forms and 351 Electric power generation, transmission and distribution.
