Zhonghe Gasification Signs Contract for Circular Fluidized Bed Gasification Project with Xinjiang Dongfang Hope Carbon Co., Ltd. Author/Source: Gasification World Date: 2023-04-23 Clicks: 13 Recently, Zhongke Hefei Gasification Technology Co., Ltd. (hereinafter referred to as “Zhonghe Gasification”) signed a contract with Xinjiang Dongfang Hope Carbon Co., Ltd. for a circular fluidized bed gasification project, aiming to collaborate on the construction of a gas station at the factory site. Xinjiang Dongfang Hope Carbon Company is a wholly-owned subsidiary of the Dongfang Hope Group. Located in the Wucaiwan Industrial Park of the Zhundong Economic and Technological Development Zone in Xinjiang, the company uses delayed petroleum coke and solid modified asphalt as raw materials, and produces pre-baked anodes through calcination; its current production capacity is 700,000 tons of pre-baked anodes per year. The project includes carbon anode production facilities, waste heat utilization and power generation systems, gas generator units, as well as auxiliary systems (including air separation and circulating cooling water systems). Adhering to the principle of making full use of local coal resources, and taking into account the characteristics of the high-alkali coal in Zhundong, such as its low melting point and high content of calcium, sodium, and potassium, Zhonghe Gasification has designed a pulverized coal gasification plant using circulating fluidized bed gasification technology. The plant consists of 2 sets of circulating fluidized bed gasifiers, each with a capacity of 40,000 Nm3/h; once operational, it will supply heat energy to the calcination area, the chlor-alkali cathode and anode production areas, as well as the aluminum processing area. This project is the third high-alkali coal gasification project constructed by Zhonghe Gasification, following the Yihua coal gasification plant project in Xinjiang and the renovation project of the Qiya circulating fluidized bed gasifier in Xinjiang. The successful operation of the Xinjiang Yihua and Xinjiang Qiya projects has fully demonstrated the strong adaptability of CGAS circulating fluidized bed gasification technology to high-alkali coal. Its exemplary effect has also made Zhonghe Gasification a common choice for an increasing number of enterprises in Xinjiang. The CGAS circulating fluidized bed gasification technology boasts core advantages such as strong adaptability to different coal types, low energy consumption and costs, high overall energy efficiency, low emissions of waste substances, and high technical reliability. In 2022, this technology passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. The evaluation results indicate that this technology is generally at the international advanced level, and it is at the international leading level in high-alkalinity coal gasification; it holds positive significance for the development of high-alkalinity coal in Xinjiang and for the growth of the local economy.
