Thread Content
In June 2022, the Xinjiang Department of Ecology and Environment issued a approval notice regarding Xinjiang Xuan Dong Energy Co., Ltd.’s project for the clean and efficient utilization of coal on a scale of 10 million tons per year, as well as a project for producing hydrogen through gasification at a rate of 100,000 m3/h. Xuandong Energy Co., Ltd. is constructing the project for the clean and efficient utilization of coal on a scale of 10 million tons per year, with differentiated quality treatment, as well as the hydrogen production via gasification at a rate of 100,000 m3/h, in three phases. The total investment for the project is 4,490 million yuan, of which 852 million yuan is allocated to environmental protection measures, accounting for 18.98% of the total investment. According to the publicly available environmental impact assessment information, coal-to-hydrogen production utilizes SE water-coal slurry gasification, sulfur-tolerant shift reaction, low-temperature methanol washing, and PSA for hydrogen production.
The equipment allocation for each process stage of the project is as follows: Gasification – 2 gasification furnaces, with a water-cooled wall and lower cooling system; 2 units in operation and 1 as backup. Transformation: Sulfur-resistant transformation, CO+H2 110,000 m3/h. Purification: Low-temperature methanol washing for CO+H2, 110,000 m3/h. PSA hydrogen production: 100,000 m3/h. Sulfur recovery: two-stage Claus process for sulfur production.
Xinjiang Xuan Dong Energy’s 100,000 Nm³/h coal gas-to-hydrogen project is located in the comprehensive energy industry zone of the Yiwu County Industrial Park in Hami. It is primarily used to supply hydrogen for the coal tar hydrogenation unit part of Xinjiang Xuan Dong Energy’s project for the clean and efficient utilization of 10 million tons per year of coal on a differentiated basis. This project includes process units such as air separation, coal preparation, gasification, shift reaction, low-temperature methanol washing, sulfur recovery, and PSA hydrogen production, along with the supporting utility systems. The air separation unit has a capacity of 40,000 Nm³/h (O₂), and it supplies process air, instrument air, and nitrogen for the entire plant.
Xinjiang Xuan Dong Energy Co., Ltd. – 10 million tons per year project for the clean and efficient utilization of coal through classification and quality differentiation.
