A pulverized coal injection system began operation at the Gary works blast furnaces on Feb. 1, 1993. This system is capable of processing more than 3500 tons of coalday to eventually supply the furnaces at a 400 lbNTHM rate. The start-up was aggressive with coal levels exceeding 200 lbNTHM within two to five weeks on the furnaces.
Aug 24, 2018 The coke facility uses SunCoke Energys low-emission technology to process coal into coke, a key ingredient in steelmaking. The technology has been recognized by the U.S. Environmental Protection Agency as setting the standard for coal processing ovens. The energy generated in the coke making process will be used in a cogeneration plant that ...
Coke Manufacturing Industry Description and Practices 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,

12.2 Coke Production 12.2.1 General Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is coked , or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke.
Belt Trippers amp Plows. Belt trippers and plows are also frequently used in the handling of coal and coke products, particularly in relation to storage applications. Both types of equipment serve as add-ons to belt conveyors to increase the flexibility of discharge, allowing for fixed and movable locations on either side of the conveyor along the length of the conveyor.
Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and, as the name implies, produces petroleum cokea coal-like material. Exports of petroleum coke accounted for about 19 of the nations finished petroleum product exports through October 2012 with most going to China and other Asian countries.
Mechels mining segment comprises facilities producing and selling coking coal concentrate, anthracites, PCI, iron ore concentrate and coke, which are chief raw materials for steelmaking. The Mechels mining facilities also produce and sell thermal coal and middlings.
Coal tar, a by-product of coke production, sees its output change with coke output. During 2005-2014, with Chinas increased demand for steel, coke output grew at an AAGR of 8.3, reaching 476.90 million tons in 2014, with actual amount of coal tar recycled amounting to about 15.70 million tons.
Petroleum coke can either be fuel grade high in sulfur and metals or anode grade low in sulfur and metals. The raw coke directly out of the coker is often referred to as green coke. For that matter, green means unprocessed. The further processing is calcining the petcoke in a rotary kiln removes residual volatile hydrocarbons from the coke.
When the coke is pushed from the oven into a railcar, it is quickly quenched to cool the coke and stop the burning process. The cooled coke is then dumped onto a coal wharf where it is taken to a facility to be screened and sized prior to being charged into the blast furnace.
