NLMK Group has placed an order with SMS group for the delivery of two gas recovery systems for its Lipetsk site. Steelmaking shop no 1, which has three 160 tonne converters, is to be equipped with a switch-over station, a gasholder with a capacity of around 60,000 cubic meters, and a gas transfer station. Steelmaking shop no 2, featuring three 330 tonne converters, will be provided with a switch-over station, a gasholder with a capacity of around 90,000 cubic meters and a gas transfer station. The switch-over stations will be installed between the primary gas blowers and the gas flares. They consist of several special-purpose valves that were designed by SMS group and constructed specifically for cyclical converter operation. They allow the system to be safely switched between flare and gas recovery mode. Both gasholders are operated with a diaphragm seal, which is adapted to suit the fluctuating climatic and operating conditions. The new gasholders will enable all three converters to be operated, with two converters running simultaneously in gas recovery mode.
SMS group’s scope of supply covers the engineering, delivery of components, and technical support for erection and commissioning.
Commissioning of the environmental facilities is scheduled for 2022.
