On February 26, the approval decision issued by the Maoming Ecology and Environment Bureau regarding the environmental impact report for Sinopec Maoming Branch’s 20,000 tons per year coated asphalt production facility was made public. Construction unit: Maoming Branch of Sinopec Corporation. Environmental assessment agency: Guangdian Metrology Evaluation and Consulting (Guangdong) Co., Ltd. Construction location: Refinery area, No. 8, Fangchanqian West Road, Hongqi Sub-district, Maonan District, Maoming City. Construction content and scale: A new coating asphalt plant with an annual production capacity of 20,000 tons will be built. Using the ethylene tar produced by the ethylene cracking unit in the chemical plant area of the Maoming branch as the main raw material, this plant will produce 20,000 tons of coating asphalt per year through processes such as raw material heating, reaction, product separation, and asphalt shaping; meanwhile, by-products in the form of reacted heavy oil and reacted light oil will be generated. The project includes auxiliary facilities such as an asphalt-covered warehouse, initial rainwater tanks, oily wastewater tanks, a substation, and cabinet rooms; all other utility projects make use of existing ones.
