Russian Steelmaker, NLMK, Novolipetsk Iron and Steel Works, has launched a recovery complex to capture and process chemical by-products from steelworks coke batteries. The company’s total investment in the project accounted to nearby RUB 4.6 bn (USD 73 million).
The project will enable an increase in the production of raw materials for the chemical industry and for agribusiness, and halve the shop’s air emissions.
The recovery complex is built with the use of best available technologies (BAT). It captures the entire volume of gas generated during the heating of coal in coke oven batteries and purifies it, while the chemicals released during the purification process are further processed into products for third parties. Purified coke oven gas is used as fuel for the coke ovens themselves and for the site’s power plants.
Konstantin Lagutin, NLMK Group Vice President, Investment Projects, said: “The chemical by-products recovery complex that combines coke oven gas flows from all coke batteries is practically waste-free. It is designed using advanced technologies and ensures efficient gas purification, process safety, and high environmental performance.”
