NLMK upgrades coke-chemical production

Novolipetsk Steel (NLMK) has re-commissioned a 460,000 tonnes per year coke battery #2 after major renovation. The upgrade of the coke production facilities will result in improved reliability, decreased environmental impact and improvement in the quality of products. Coke battery #2 is the fourth coke production unit at the Lipetsk site with emissions trapping technologies - dust-free coking chamber charging and discharging. The implementation of high technology control systems will provide efficient coke gas combustion and prevent its emission into atmosphere. The operation of a modern coke line will significantly improve the personnel working conditions. Revamping coke battery #2 took 24 months. Total investments into the project was around USD 50.5 mln. Since the Technical Upgrading Program started in 2000, NLMK has reconstructed coke batteries #1, #5, and #6, which are now considered to be among the most efficient and environmentally safe in Russia. Equipment was upgraded and progressive coke gas cooling technology was implemented in coke batteries ##1- 4. To provide high quality of produced coke, the storage space for coal concentrate was redesigned and input coal blending got new equipment and technologies.
