Thread Content

I. Name and overview of the construction project: Project name: Phase I of the alcohol-based high-end chemicals project at Anhui Carbonxin Technology Co., Ltd； Project nature: Expansion ； Construction location: Within the Linhuan area of the Anhui (Huaibei) New Coal Chemical Synthesis Materials Base, located on the north side of Huaxia Road in the park, on the west side of Huaixin South Road, and to the south of the CarbonXin Phase II ethanol production facility ； Project investment: Total investment of 1,179.2608 million yuan ； Construction details: The new plant site for the project covers an area of approximately 181,333.3 square meters ； This includes the main production units, storage and transportation facilities, as well as auxiliary systems; the main production units comprise the formaldehyde plant, acetaldehyde plant, pyridine base plant, and pentaerythritol plant ； Storage and transportation facilities include tank farms, loading/unloading stations, and interplant and intraplant pipelines ； The supporting utility and auxiliary facilities include a refrigeration station, air compression station, circulating water station, cabinet room, substation, initial rainwater tank, accident tank, etc. Once completed, the project will produce 170,000 tons of formaldehyde, 70,000 tons of acetaldehyde, 30,000 tons of pyridine base, and 30,000 tons of pentaerythritol per year; formaldehyde and acetaldehyde serve as raw materials for pyridine base and pentaerythritol. Basic information on existing projects: Anhui Carbonxin Technology Co., Ltd. currently has 3 major project initiatives, namely the comprehensive utilization project for coke oven gas, the comprehensive utilization project for methanol, and the project for producing 30,000 tons of ethylamine per year. Divided by Huayin Road, the facility is constructed in two sections in the north and south. The plant area on the north side of Huayin Road covers a total area of approximately 51.49 hectares, and it houses the facilities related to the comprehensive utilization of coke oven gas, as well as those related to the comprehensive utilization of methanol; in addition, it includes the auxiliary systems, environmental protection measures, and storage and transportation infrastructure required for these two projects ； The southern plant area covers approximately 26.86 hectares, and it mainly houses the ethanol production unit related to the comprehensive utilization of methanol, the project for producing 30,000 tons of ethylamine per year, as well as the supporting infrastructure, environmental protection systems, and storage and transportation facilities for these two projects. Pollution control measures for existing projects: The existing project is equipped with 46 exhaust stacks in total. Exhaust gases containing particulates are treated by bag filters before being released to meet regulatory standards; sulfur recovery exhaust gases are processed through a \"quench tower + hydrogen peroxide washing + electrostatic demister\" system before being released to meet standards. Exhaust gases from the low-temperature methanol washing process are discharged after being washed with deionized water. Exhaust gases from the tank area and loading/unloading areas are treated using oil and gas recovery facilities before being released. Exhaust gases from the hazardous waste storage area are treated with activated carbon adsorption units. Exhaust gases from the wastewater collection tanks are treated through a \"spraying + biological filter\" system before being released to meet standards. Exhaust gases from the ethylamine production unit are treated using TO + SCR systems. All exhaust gases generated within the plant are effectively treated before being released ； The wastewater is temporarily stored in the on-site wastewater collection tank before being sent to the park’s sewage treatment plant for further treatment ； Noise is treated through measures such as sound insulation, vibration reduction, noise cancellation, and sound absorption before being discharged to meet standards ； Solid waste is properly disposed of, preventing secondary pollution.
