Public notice on the environmental impact assessment review for Inner Mongolia’s 10,000-ton biomass conversion test facility: On September 18, a public notice was issued regarding the planned review of the environmental impact assessment documents for China General Nuclear Group’s pilot platform project for the development of high-efficiency biomass gasification technology on a 10,000-ton scale in Balin Left Banner. Project Name: Pilot Platform Project for the Research and Development of 10,000-ton-class High-efficiency Biomass Gasification Technology in Balin Left Banner
Construction Unit: CGN Guanghe (Chifeng) New Energy Co., Ltd.
Basic Information: This project involves comprehensive technical experiments and research on key fundamental issues as well as engineering technical problems related to the biomass preprocessing – powder conveying – gasification process. It includes the construction of a set of straw preprocessing experimental equipment with a capacity of 2 tons per hour, as well as a set of gasification test rigs. Additionally, auxiliary facilities such as a control room, an analysis room, and storage areas are also built. Construction location: Within the Fenghuangshan Industrial Cluster in the Balinzuo Industrial Park (formerly the Fenghuangshan Chemical Industry Park in Balinzuo Banner, Chifeng City, Inner Mongolia Autonomous Region). Environmental assessment agency: Inner Mongolia Senmao Engineering Management Co., Ltd. Environmental protection measures to be adopted for this project: Information on the environmental impact of this project and the corresponding environmental protection measures: 1. Exhaust gases: The dust generated during crushing is treated using bag filters before being emitted through exhaust stacks that are at least 15 meters high. The exhaust gas from natural gas boilers is treated using low-nitrogen combustion, and the combustion exhaust gas is discharged through an exhaust stack with a height of no less than 8 meters. The combustion exhaust gas from the furnace and the drying exhaust gas are pre-treated in a cyclone dust collector; after that, they are combined with the exhaust gas from the drying oven and the exhaust gas generated during biomass transportation. This mixture is then subjected to wet dust removal and bag filtration before being discharged through an exhaust stack. The exhaust gas generated during grinding is treated in a separate bag dust collector before being discharged through an exhaust stack. The biomass conveying dust is treated by a bag filter on the top of the silo before being discharged, with the discharge outlet at a height of 35 m. Vaporization, wastewater vaporization, and wastewater exhaust gases are treated in an alkaline spray tower before being discharged through exhaust stacks with a height of no less than 15 meters. Ignition exhaust gas, pressure relief exhaust gas, nitrogen displacement exhaust gas, and syngas are disposed of through a 20m flare. 2. Wastewater: A new 68 m³ ash tank will be constructed, and the wastewater treatment system will consist of a grid screen, a regulating tank, an AO process unit, and a secondary sedimentation tank; the treatment capacity is 2 m³/h. 3. Noise: Use low-noise equipment and adopt measures such as basic vibration reduction and sound insulation. 4. Solid waste: Domestic waste is collected in trash bins and handed over to the park’s sanitation department for centralized disposal. General industrial solid waste: Ash and sludge are directly loaded onto vehicles for disposal by the sanitation authorities after dewatering; they are not stored on-site. Dust collected from dust removal processes is reused in production. Hazardous waste: A new 4 m2 hazardous waste storage area will be constructed; used lubricating oil and oil-soaked rags will be stored in this area before being disposed of by a qualified entity.
