Severstal Karelsky Okatysh to Cut SO2 in Iron Ore Pellet Plant

Russian steel maker Severstal’s iron ore mining and processing plant Karelsky Okatysh in Russia plans to reduce sulfur dioxide emissions by using a desulfurization unit on a roasting machine. Sulfur dioxide is released during pellet burning. Electrostatic precipitators for gas cleaning of roasting machines do not delay it, therefore it was decided to build a pilot desulfurization unit. The equipment is mounted at the site of the roasting machine No 3. In the installation, the firing gases will be sprayed with milk of lime. The launch of the pilot plant will allow simulating the purification processes for various parameters of waste gases (temperature, sulfur dioxide content, pressure) in the production of various types of products.

Pilot tests of new equipment and training of specialists from the firing section are scheduled for May. If the "pilot" proves its effectiveness, a project of an industrial desulfurization unit will be developed, taking into account the site for utilization of a by-product sludge.
