On September 23, the implementation plan of ultra-low emission transformation of cement and coking industry in Guizhou Province was released.
The circular calls for the implementation of ultra-low emission transformation of cement clinker production enterprises (excluding mines), independent grinding stations (including cement enterprises producing special cement and co-disposing solid waste) and coking enterprises (including semi-coke production).
By 2028, the province's cement industry will strive to complete the transformation of 80% clinker production capacity. Cement enterprises that have completed the ultra-low emission transformation should check and fill in the gaps according to the scheme to ensure that the corresponding processes meet the requirements of the scheme on schedule. Control index
of organized emission: under the condition that the reference oxygen content of cement enterprises is 10%, The hourly average emission concentration of particulate matter, sulfur dioxide and nitrogen oxides in waste gas from the waste heat utilization system of cement kiln and kiln tail shall not be higher than 10mg/m ³, 35mg/m ³ and 50mg/m ³ respectively. Control measures
for unorganized emission: for unorganized emission sources such as material storage, material transportation, production process and open liquid level (coking), effective control facilities such as sealing and sealing shall be adopted on the premise of ensuring safe production. The unorganized emission control facilities and production facilities operate normally synchronously, there is no visible smoke and dust escaping from the dust-producing points and production facilities, and the plant area is clean and tidy without dust accumulation and obvious odor. Requirements for
clean transportation: the proportion of raw materials and fuels in and out of cement enterprises, materials and products in and out of coking enterprises transported by clean means such as railways, waterways, pipelines, tubular belt conveyors and belt corridors shall not be less than 80%; For enterprises that fail to meet the standards, all the vehicles transported by automobiles shall adopt new energy or national six emission standard vehicles. The cement industry gives priority to the use of clean transportation mode for product transportation, and all vehicles for automobile transportation are new energy or national six emission standard vehicles. New energy transport vehicles are used in the plant (by the end of 2025, the sixth national emission standard vehicles can be used). In principle, non-road mobile machinery uses new energy, and those without corresponding products meet the fourth and above national emission standards (by the end of 2025, non-road mobile machinery can adopt the third national emission standards).
The cement industry will soon be incorporated into the carbon trading market, and the importance of green low-carbon transformation has become increasingly apparent. To this end, China Cement Network will hold the " 2024 China Cement Double Carbon Conference and the 12th Energy Conservation and Environmental Protection Technology Exchange Conference " in Wuhu Conch International Hotel on October 24-25. The conference will focus on the core issues of low-carbon development and green upgrading in the cement industry, discuss the application of energy efficiency improvement and energy-saving and carbon reduction technologies, and how the cement industry can use the carbon trading mechanism to promote its low-carbon transformation.
