In August 2015, Qingdao Eco-Strong Technology Engineering Co., Ltd. successfully undertook the EPC project for the boiler flue gas desulfurization and denitrification of Zhongce Rubber Group Co., Ltd. This project adopted the advanced ultra-low emission technology from Zhejiang University. After the completion of this project, the NOx emission concentration will be below 50 mg/Nm3; the SO2 emission concentration will be below 35 mg/Nm3; and the dust emission concentration will be below 5 mg/Nm3, truly achieving ultra-low emissions.
