On December 11, 2024, with the successful lifting of the last cold box panel and roof, the cold box for the Yingcheng Xindu Chemical Project was completed. The capping of the cryogenic tank represents an important milestone in the project’s construction, signaling the successful completion of the heavy-lift installation of the air separation cryogenic tank and the full entry into the installation phase. Upon completion, the project will establish a nationally leading demonstration industrial chain for the \"brine-salt-alkali-fertilizer\" cycle in the salt chemical industry, facilitating the green and low-carbon transformation of Hubei’s salt chemical industry and enhancing the competitiveness of its related industrial clusters. The project is located in the Chemical Industry Park of Yingcheng City, Hubei Province, with a total investment of 7.5 billion yuan and covers an area of about 2,000 mu. The Yingcheng Xindu Chemical Salt Industry Green Transformation and Product Structure Adjustment and Upgrading Project involves the construction of facilities capable of producing 600,000 tons per year of water-soluble compound fertilizers, 400,000 tons per year of slow- and controlled-release compound fertilizers, 700,000 tons per year of refined salt, 200,000 tons per year of sodium bicarbonate (baking soda), and 50,000 tons per year of melamine ； Renovation and expansion of 300,000 tons of sodium hydride and 700,000 tons of synthetic ammonia production facilities ； 300,000 tons of light alkali were converted into heavy alkali. Among them, synthetic ammonia production uses the water-cooled wall waste boiler gasifier (Jinhua Furnace 3.0) developed by Beijing Qingchuang Jinhua Technology Co., Ltd., with two units in operation and one as a backup. Vaporization pressure: 6.5 MPa, total gas flow rate: 205,000 m3/h (CO+H2). The shift unit of the Xindu Chemical Salt Chemical Green Transformation and Product Structure Adjustment and Upgrading Project utilizes the advanced two-stage controllable heat transfer shift technology developed by Nanjing Dunxian Chemical Technology Co., Ltd.; through two stages of isothermal shifting, the dry basis CO content at the outlet of the shift system is kept at ≤0.7%. This process flow, along with the accompanying DX-V type isothermal conversion furnace, has been successfully applied in the 600,000-ton synthetic ammonia projects of Henan Jindadi Phase III, Phase IV, and Phase V, delivering excellent performance across all parameters. At present, Xindu Chemical is implementing the \"Green Transformation of the Salt-Chemical Circular Economy Industry Chain and Product Structure Adjustment and Upgrading Project.\" By building a facility capable of producing 700,000 tons of synthetic ammonia along with related upstream and downstream projects, the company aims to gain greater control over upstream nitrogen resources, complete the \"salt-alkali-fertilizer\" industry chain, and advance the adjustment and upgrading of its product portfolio as well as market expansion. The entire project is expected to be completed by December 2025.
