Primetals Technologies completes first ultra-low emission technology project for BOF off-gas at Changzhou Eastran

In late 2020, Primetals Technologies received the final acceptance certificate (FAC) for a newly installed advanced gas cleaning system based on wet electrostatic precipitator (WESP) technology. This first project was successfully implemented at Changzhou Eastran Special Steel Co. Ltd. in China’s Jiangsu province. Based on very strict requirements of the local city government an emission limit of 10 mg/Nm³ was requested for the steelmaking plant with two 80t basic oxygen furnaces (BOF). Primetals Technologies developed a suitable solution for the customer in terms of performance and minimal space requirement. The contract was signed in February 2019 and the plants for both BOF lines were commissioned in March 2020. Clean gas dust emission values of approximately 5 mg/Nm³ were measured during the performance tests later in 2020 and the final acceptance certificate was subsequently issued by Changzhou Eastran.
