Chinese steel producer Shandong Iron & Steel Corporation Limited (Shansteel) has ordered a selective waste gas recirculation (SWGR) system from Primetals Technologies for its new sinter plant in Rizhao, Shandong Province. It is the first order for Primetals Technologies from mainland China for this well proven environmental solution after several units have previously been installed in Austria, South Korea and Taiwan, which have successfully demonstrated the positive impact on environmental emission reduction and operation cost saving. With a waste gas recirculation rate of up to 40 percent, the SWGR reduces waste gas emissions to the atmosphere by 770,000 m3/h. In addition, coke consumption for the sintering processing is reduced by approximately 5 percent. Due to the lower waste gas flow rate, downstream gas cleaning facilities can be designed 30 percent smaller. The startup of phase 1 of the new sinter plant is scheduled for September 2017.
