Fluidized-bed gasification at 4.0 MPa: Public notice on the environmental impact assessment for Xinjiang Qinghua’s coal slime utilization project. Recently, in accordance with the relevant regulations regarding the approval process for environmental impact assessments of construction projects, the Department of Ecology and Environment of the Xinjiang Uygur Autonomous Region accepted the environmental impact assessment report for the coal slime utilization project developed by Xinjiang Qinghua Energy Group Co., Ltd. The construction site is located in Area B of the Yidong Industrial Park, Yining County, Ili Kazakh Autonomous Prefecture, Xinjiang; there is currently available vacant land at the Xinjiang Qinghua Industrial Park. The total investment amounts to 302.22 million yuan, of which 5.8 million yuan is allocated to environmental protection measures. Capital nature technical upgrade. Construction scale and scope: The project utilizes high-pressure fluidized-bed gasification technology to produce raw coal gas. The main production units include coal preparation, gasification, and slag discharge systems. The total designed capacity is 3.6 million m3/day (nominal capacity). Once completed, the project will replace the 3 existing Lurgi gasifiers at Qinghua Company. After the project is put into operation, the gasification section will no longer generate difficult-to-treat phenol-containing wastewater. Meanwhile, the amount of waste gas, wastewater, and solid waste generated and emitted by each unit in the technical upgrade project is lower than that of the existing Ruqi gasifiers; as a result, the overall energy consumption decreases, which has a positive impact on improving the regional environmental quality.
