In atmosphere governance field, CIE not only gets hold of frequently-used and advanced desulfurization and denitration technology and process in China, such as ammonia process, magnesium desulphurization technology, SCR denitration technology, multipoint dedusting, pipe network design, etc., but also it has made its independent research and development in current sintering flue gas purification field available, that is, the most advanced technology - activated carbon technology for flue gas purification, which is the preferred technique of ultra-low emissions in iron and steel industry that have been applied in several projects including Baosteel Zhanjiang iron and steel base, Baosteel headquarters, Anyang Iron and Steel, etc.
◎Activated carbon flue gas treatment technology: not only taking sulfur, saltpetre, dioxin, heavy metals, dust and other pollutants off, but also making deep flue gas purification technology of recycling dependent products available.
◎SCR denitration technology: the technology has simple construction, convenient operation and high denitration efficiency without accessory substance.
◎Circulating fluidized bed method: the system has simple process and stable operation without corrosion prevention.
◎Ammonia - ammonium sulfate method: it has high sulphur removal efficiency available to use sulphur dioxide recycling.
◎Limestone - gypsum wet method: it has mature technology, stable operation and high sulphur removal efficiency.
◎Baosteel Guangdong Zhanjiang base project and flue gas purification facility engineering of sintering project adopt activated carbon processes for flue gas purification.
◎No. 1, 2 and 3 sintering machine flue gas desulphurization desulfurization EPC engineering of Anyang Iron and Steel Incorporated Company, the largest project of one-time environment protection upgrade and renovation in the field of flue gas cleaning on iron and steel in China adopting activated carbon processes for flue gas purification, which various indicators are better than its design value and lower than the “26+2” Special emission limit standard.
