UrBC, Magnitogorsk, Chelyabinsk Region, April 24, 2017. Magnitogorsk Iron & Steel Works (MMK) is getting the obsolete gas-filtering facilities at its electric steel-smelting department replaced with newer and more efficient units that will decrease the plant’s harmful atmospheric emissions dramatically. The emissions currently come from MMK’s DSPA 32, the THF steel-smelting vessel, the company reports.

The replacements will cost 1.2bn RUR to go through with; the launch of the new units has been scheduled for July 2017, with an expected drop in emissions estimated at over 1,800,000 kg a year.

The new equipment is meant to trap, cool, and filter the furnace gases coming from the steel-smelting unit itself as well as the fugitive emissions that are currently not getting into the gas-filtering ducts. The DSPA 32 gas filtering appliances comprise three two-section bag filters with a new design (twenty filtering sections in each filter and horizontally oriented dust-trapping ducts); five DR 28 smoke exhausters (four operating ones and one back-up one) with the capacity of 530,000 m3 per hour and a 1-megawatt-strong engine in each unit; dust-removing appliances with a dust-free system for loading the dust into trucks; a compressed air pumping station to keep the bag filters running; a power substation and an inflow exhaust ventilation unit. The entire facility will process 1.32m m3 of gases every hour.
