On April 21, China Wuhuan Company successfully signed an engineering design contract for the upgrade project of the raw material processing route at Anyang Chemical Industry Group Co., Ltd. In January 2020, it was learned that following the approval of the safety requirements for the upgrade project of the raw material processing route at Anyang Chemical Industry Group Co., Ltd., the environmental impact assessment report for this project was also approved by the Anyang Environmental and Ecological Bureau recently. Due to outdated processes and aging equipment, high production costs, and low efficiency, the gasification units (atmospheric pressure fixed-bed batch gasification, gas holders, atmospheric pressure desulfurization, etc.), purification units (medium-temperature shift, alkaline scrubbing for desulfurization and decarbonization, low-temperature shift, advanced desulfurization, methanation reactors, etc.), ammonia synthesis units, and urea production units in the Anhua Group’s original production facilities have ceased operation. One set each for ammonia/urea production, 37–52# fixed-bed reactors (a total of 16 units), as well as the purification systems, Boiler No. 4, Boiler No. 8, and waste co-combustion furnaces, are planned to be dismantled and used as land for the construction of this new project ； The coal yard is upgraded and renovated based on its original footprint. Upon completion of this project (expected by the end of 2021), the atmospheric pressure fixed-bed batch gas generators (30 units in total) and the purification systems will be shut down and removed. The two ammonia synthesis units will also be shut down and removed. The new ammonia synthesis units and the existing ethylene glycol production facilities will be supplied with raw gas by the new water-coal slurry furnaces and purification systems, while gasifiers No. 1–4 will continue to operate to supply raw gas for the existing methamine/DMF and sodium formate plants as well as the new formamide production facility. Meanwhile, 200,000 tons of ethylene glycol will be produced annually, along with 10,000 tons of DMC, 10,000 tons of ethanol, and 0.2 tons of diethylene glycol. The total investment for the project is 3,666.18 million yuan, with environmental protection investments amounting to approximately 26.49 million yuan, accounting for 0.72% of the total investment.
