    Using Zhundong Coal to Produce Synthetic Ammonia and Recover Carbon Dioxide as Gasification Agent

    Using Zhundong Coal to Produce Synthetic Ammonia and Recover Carbon Dioxide as Gasification Agent

      Sinochem News.
    com News from July 21 to 23, the 2021 China Nitrogen Fertilizer and Methanol Technology Conference hosted by China Nitrogen Fertilizer Industry Association was held in Jincheng, Shanxi

    At the meeting, Yu Queshi, the general manager of the Sinopec Gasification Company, a subsidiary of the Chinese Academy of Sciences, gave a report on "System Solutions for Syngas Production by Circulating Fluidized Bed Coal Gasification Technology"

    According to the report, the application of this technology in the 400,000-ton/year synthetic ammonia plant of Xinjiang Yihua Chemical Co.
    , Ltd.
    is good, realizing 100% use of Xinjiang’s local Zhundong coal, completely solving the problem of high alkali, low ash, and low ash.
    The melting point and viscosity temperature are special and difficult to use.
    Up to now, a single furnace has been continuously and stably operated for 182 days


      The successful application of this technology allows Xinjiang Yihua’s own coal resources to be fully utilized, and provides a very competitive raw material support for the development of downstream carbon fixation product melamine

      According to Zhang Zhonghua, Secretary of the Party Committee of Xinjiang Yihua, Xinjiang Yihua is the first Hubei-aided chemical enterprise in Xinjiang Zhundong Economic and Technological Development Zone that has been completed and put into operation and realized the transformation of resources on the spot.
    The capacity is 20 million tons, and the coal cost is less than 100 yuan/ton

    Relying on its own coal resources, the company introduced Italian Eurotech technology in 2014 and built the world's first fourth-generation high-pressure process 80,000 tons/year melamine plant

    In 2019, the introduction of the circulating fluidized bed gasification technology developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences has solved the industry problem of the efficient and clean use of Zhundong coal for the production of synthetic ammonia.
    The recovered carbon dioxide is used as a gasification agent, which greatly reduces the equipment Carbon emissions have significantly improved the competitiveness of melamine products


      Zhang Zhonghua said that breakthroughs in coal gasification technology will inject a "cardio booster" into the company's green development.
    In the next five to ten years, Xinjiang Yihua plans to develop a 1 million tons/year melamine project to achieve low-emission conversion of coal resources and actively respond with practical actions.
    The national "carbon peak and carbon neutral" strategy

    At present, the project has been included in the list of key plans and major projects of the Zhundong Economic and Technological Development Zone in Xinjiang, and is being actively promoted
