Zhonghe Gasification: Xinjiang Yihua Gasification Project Covered in Xinjiang News Broadcast Author/Source: Zhongke Hefei Gasification Technology Co., Ltd. Date: 2022-03-02 Views: 14 On February 25, the Xinjiang Yihua Gasification Project, constructed by Zhongke Hefei Gasification Technology Co., Ltd. (hereinafter referred to as “Zhonghe Gasification”), was featured in the Xinjiang News Broadcast, attracting attention as a model project for the Xinjiang Autonomous Region’s strategy to convert its strategic resources into valuable products. This set of equipment is the first high-alkali coal circulating fluidized bed gasification unit in China. Xinjiang has enormous reserves of high-alkali coal; in the Zhundong region alone, the estimated reserves amount to 390 billion tons. Due to its low ash melting point and problems such as slag formation and fouling, high-alkali coal can easily cause coking and corrosion in gasifiers; however, the circulating fluidized bed gasification technology used by Zhonghe Gasification has overcome this challenge! Since its official commissioning, the project has been operating smoothly with excellent performance metrics. Previously, the conversion unit at Xinjiang Yihua had to be shut down for maintenance every 3 months; now, the continuous operation time has been extended to 7 months, resulting in an **improvement in both the stability and automation level of the system. The successful operation of this project also provides technical and equipment support for the large-scale gasification and conversion of the vast coal reserves in Xinjiang’s Zhundong area. It is reported that Xinjiang Yihua Chemical Co., Ltd. is the first large-scale industrial enterprise in Zhundong to achieve on-site conversion of coal, and it possesses the world’s largest single-unit melamine production facility. By the end of 2021, the company completed the upgrade of its production lines and focused its efforts on its core competitive industrial chains; in January it achieved sales revenue of 450 million yuan, with profits increasing by 260% compared to the same period last year. The upgraded oxygen-enriched circulating fluidized bed gasification technology solves the industry challenge of using Shuidong coal efficiently and cleanly in ammonia synthesis production. The recycled carbon dioxide is used as a gasifying agent, reducing the carbon emissions of the facility and enhancing the competitiveness of the final product, melamine. As the industrialization platform for the CAS Hongguang special project titled \"Industrialization of Circulating Fluidized Bed Gasification Technology,\" Zhonghe Gasification will continue to promote the application of this technology in various fields, leveraging its core advantage of strong adaptability to different types of coal. It will help customers transform their local resource advantages into industrial strengths, thereby fostering the green, low-carbon, and high-quality development of the modern coal chemical industry.
