CONSTRUCTION OF GAS PURIFICATION ON THE SINTERING MACHINE № 2 OF THE «ZAPORIZHSTAL» STEEL WORKS IS IN THE ACTIVE PHASE

NEWS

This was told by Igor Chernjak, the Director for labour, industrial and technogenic safety of the «Zaporizhstal» Steel Works during the working meeting which passed at construction site of gas purification of the sintering machine № 2: «The works on construction of gas purification at the sintering machine № 2 have begun one month ago, and at this stage one third is already done – works on foundation are finished, more than 300 tons of metal structures are mounted, erection of equipment for gas purification is going on».

Let’s remind that in May, 2013 the Steel Works has put into operation sintering machine № 1 with highly technological gas purification and two electric precipitators (investments composed 240 million UAH). In total, there are six sintering machines at the Steel Works, each of which is planned to equip with modern purification equipment. Construction of each new gas purification will allow to reduce industrial emissions of the Steel Works up to 10 %. That is, with putting into operation of gas purification on the sintering machine № 2, the emissions of the Steel Works will be reduced on 20% from the total emissions. Investments into construction of gas purification for the sintering machine № 2 composed 80 million UAH.

The principle of work of new gas purification of the sintering machine № 2 includes multistage flume cleaning: gas is cleaned in bag filters, the trapped iron-containing dust from the bag filters comes back into sintering production. New gas purification equipment will ensure at the sintering machine № 2 cleaning of air from dust up to 20 mg/Nm3, as for sulphur dioxide content less than 400 mg/Nm3, that will correspond to the European normative standards of emissions, and also will allow stage by stage to reduce discharge of sludge waters from water recycling system of the sintering plant.

Despite the most complicated economic situation in Ukraine, the Steel Works continues to put up the monetary funds into ecological upgrading of the Steel Works. The Steel Works invested more than 250 million US dollars on these purposes since August 2012.
