Xinjiang Zhundong Coal Gasification Technical Transformation Project Approval Author/Source: Chemical Network Coal Chemical Industry Date: 2023-04-20 Click rate: 9 Xinjiang Oriental Hope Carbon Co., Ltd. is a wholly-owned subsidiary of Oriental Hope Group Company. Together with other enterprises under the Oriental Hope Group—Xinjiang Oriental Hope Nonferrous Metals Co., Ltd., Changji Jisheng New Building Materials Co., Ltd., Xinjiang Oriental Hope New Energy Co., Ltd., etc., it has formed an industrial cluster covering industries such as electric power, electrolytic aluminum, industrial silicon, carbon, and basic chemical raw materials. Oriental Hope Carbon Co., Ltd. is located in Wucaiwan Industrial Park, Zhundong Economic and Technological Development Zone, Xinjiang. The company uses delayed petroleum coke and solid modified asphalt as raw materials, and produces prebaked anodes after calcination. The current production capacity is 700,000 tons of prebaked anodes. The project includes carbon anode production equipment, waste heat utilization and power generation equipment, gas generator equipment, and public auxiliary projects (including air separation, circulating cooling water systems, etc.). The gasifier device supporting the project consists of 18 atmospheric fixed-bed gasifiers (two-stage gasifiers) with a diameter of 3.6m to produce gas. A single furnace has low gas production, high coal consumption, and high operating costs. Due to the low reaction temperature in the furnace, the tar and phenolic substances produced during the gasification process turn into wastewater and tar that are difficult to treat in the gas scrubbing unit and decoking unit. Through market research, Oriental Hope Carbon Company decided to implement technical transformation of the existing gas generators in the gas industry area, replacing the existing 18 atmospheric pressure fixed-bed gasifiers with 5 40,000Nm3/h circulating fluidized bed gasifiers. This technical transformation project plans to use the atmospheric circulating fluidized bed gasifiers developed by Zhongke Hefei Coal Gasification Technology Co., Ltd. using the independent intellectual property rights of the Institute of Engineering Thermophysics, Chinese Academy of Sciences. It is planned to be constructed in two phases, with 2 units built in the first phase and 3 units built in the second phase. Taiwan. Xinjiang Oriental Hope Carbon Co., Ltd., the construction unit of the gas generator technical renovation project in the gas working area: Construction properties of Xinjiang Oriental Hope Carbon Co., Ltd.: Technical transformation construction site: Construction content within the existing factory area of Xinjiang Oriental Hope Carbon Co., Ltd. in Wucaiwan Industrial Park, Zhundong Economic and Technological Development Zone, Xinjiang: Construct 5 40000Nm3/h circulating fluidized bed gasifiers and supporting facilities to replace the existing 18 gasifiers and supporting facilities. The construction will be divided into two phases, with 2 units built in the first phase and 3 units built in the second phase. Construction scale: The gas production scale of the first phase project is 80,000Nm3/h (approximately 652.8 million Nm3/a), and the gas production scale of the second phase project is 120,000Nm3/h (approximately 979.2 million Nm3/a). After the first and second phases are completed, the total gas production scale can reach 200,000 Nm3/h (approximately 1,632 million Nm3/a). Covered area: 1.68hm2 construction progress: The construction period of the first phase of the project is about 8 months (planned to start construction in May 2023 and expected to be completed in December 2023), and the construction period of the second phase of the project is 8 months with a total investment of: 455.58 million yuan, all raised by the enterprise itself
