According to relevant sources of the Sichuan Yilong County County Party Committee and Confidential Bureau, in 2009, Sichuan Yilong County focused its work on the oil and gas chemical industry, and cooperated with the industrial development plan. Yilong County planned to raise funds to build a chemical industrial park project. At present, natural gas industrial park planning has been approved by the provincial government, including 15 km2 of the new natural gas chemical park in the county; a daily throughput of 22,000 tons of freight wharf, a gas distribution station, 4.7 km of Binjiang highway, and flood control The embankment is 3 kilometers; the planned annual gas use index is 4.5 billion cubic meters, 27 billion yuan is invested, and natural gas chemical industry, vulcanization and other industrial projects such as the acetylene industrial chain are built.
Among them, it is located in Yangtong Township Purification Plant in Lishan Township, covering an area of ​​447 acres, with a construction scale of 12 million cubic meters per day, two parallel rows of processing capacity of 6 million cubic meters per day, and a single set of equipment handling capacity being the largest in China. After the sewage is treated, it basically achieves zero emission and reaches the international advanced level. It is an environmental protection project. The purification plant desulfurization process uses the methyl diethanolamine (MDEA) method, the dehydration uses the TEG absorption method, the sulfur recovery adopts the secondary conventional Claus method, and the tail gas treatment adopts the reduction absorption method introduced by BV. In addition, the park planning projects include: Phase I projects (iminodiacetonitrile, glyphosate, ammonium sulfate, formic acid, hydrochloric acid, dimethyl ether, acetic acid), and the second phase acetylene industry projects (acetylene, methanol, butanediol, polytetrahydrofuran, PBT, Butyl Butyrate, Polymethanol, Vinyl Acetate, Synthetic Ammonia, Urea, Melamine, Caustic Soda), Phase III Olefins Industry Project (Methanol, MTO, LKPE/EVA, Polypropylene, Maleic Anhydride, Petroleum Resin, Acetic Acid/Anhydride , cellulose acetate, acetylene acetate) and downstream products related projects. According to the relevant personage of the County Commissioner of the Yilong County, Sichuan Province, the local government has successively carried out related project recommendations and investment promotion work.
