Construction of Weihua Group’s 50,000-ton carbon dioxide capacity expansion project commenced. According to Weihua Group, on March 17, 2021, the civil engineering work for the 50,000-ton carbon dioxide production facility as part of Kewei Company’s capacity expansion project officially started. This means that 70 days from now, a new compressor plant for these devices will be built on the site of Kewei Company’s former office building, and more than three months later, 50,000 tons of high-purity carbon dioxide will begin to be produced on a commercial scale. Upon completion of the project, the company’s new and existing facilities will together release a production capacity of nearly 70,000 tons. Kewei Company’s project to upgrade its production capacity to 50,000 tons of carbon dioxide per year has completed all the preliminary pre-evaluation reports regarding safety, environment, and occupational health. The process package and design institute have been selected, and the bidding process for the three key equipment items—carbon dioxide compressors, chillers, and storage tanks—has been completed. The bidding processes for static equipment, chemical raw materials and catalysts, as well as key equipment, have all been completed. The control room for the renovation of the old plant’s control system was finished before the New Year. The ordering of the main equipment for the project has been completed, and the project construction is progressing in an orderly manner according to the planned schedule. As early as 2001, the company invested in building a facility capable of recycling 18 million cubic meters of carbon dioxide per year and producing 30,000 tons of food-grade liquid carbon dioxide. It mainly recycles the greenhouse gases that are normally emitted into the atmosphere during the production of synthetic ammonia. Shaanxi Weihe Coal Chemical Industry has a phase I facility with an annual production capacity of 300,000 tons of synthetic ammonia and 520,000 tons of urea, which came online in 1996. Phase II has an annual production capacity of 200,000 tons of methanol and 100,000 tons of dimethyl ether; it is commonly referred to as the DM project, and it came online in 2006. Phase 3 involves 400,000 tons of methanol, with commissioning in 2011.
