Alfa Laval - Coke oven gas plant
Cooling raw coke oven gas enables the recovery of by-products, such as tar, naphthalene, benzene, ammonia and hydrogen sulphide, from the condensate stream and gas stream which results after quenching. Today many of these by-products are actually cheaper to .
Blast Furnace, Coke Gas and Converter Gas for Power Production
Coke gas is a by-product of industrial coke production from pit coal, coke gas is created by high-temperature dry distillation of coking coals in the absence of oxygen. The gas mainly consists of hydrogen (50-60%), methane (15-50%) and a small percentage of carbon monoxide, carbon and nitrogen.
Coke Making | Industrial Efficiency Technology & Measures
Coke is a material with high carbon content and porosity. It has high resistance to breakage and low reactivity with gases, particularly CO2. Coke production is an important part of the integrated iron and steel plants using BF-BOF route, acting as a reducing agent, as a source of thermal energy, and providing physical support for the burden in blast furnace.
