ММК completes reconstruction of sulphur capture system
The launch marks completion of reconstruction of sulphur capture system № 2 (SCS-2) at the second sinter plant – an integral part of MMK’s Environmental Programme. The first stage was commissioned in summer 2015, construction of the second stage was completed in July 2016. Overall investment into the project exceeded RUB 3.5 bln. Reconstruction of SCS-2 allowed to process the total volume of gas coming from the sinter plant № 2, that is 1,400,000 normal cubic metres per hour, with degree of purification of up to 95% for sulphur dioxide and up to 97% for suspended materials, in line with the highest standards and best technologies used in the EU.
As part of reconstruction, three cleaning systems of the same type were built, each comprising two cleaning steps, electric filter and scrubber. Electric filter is used to catch solid particles (dust), while scrubbers covered with lime-wash are used to capture sulphur dioxide. The equipment was supplied by Sinosteel (China).
Reconstruction of SCS-2 started in 2013. An old sulphur capture system, which was launched in 1963 no longer complied with world sinter gas cleaning standards, was outdated, worn out and required significant investments to keep it running. Thus, reconstruction of the facility was required, which ultimately resulted in a construction of a new sinter gas cleaning complex at SCS-2.
