I. Project Overview: The BASF MDI project in Chongqing is planned to be constructed in the northern expansion area of the Chongqing Changshou Chemical Industry Park, with an investment of approximately 660,000,000 yuan. The main construction components include one set each of a 400,000 t/a *** production plant, a 300,000 t/a aniline production plant, a 400,000 t/a crude MDI production plant, a 400,000 t/a MDI refining production plant, and a 20,000 t/a MDI prepolymer production plant; in addition, relevant auxiliary facilities and utility systems are to be built, along with office buildings, analysis laboratories, warehouses, and tank areas. II. Generation, treatment, and emission of ‘three wastes’ 1. The generation, treatment, and emission of exhaust gases during the operation period of the proposed project are as follows: (1) The exhaust gases from the *** production process and those from the aniline separation unit consist mainly of C, H, and N compounds; these gases are used as fuel in the thermal decomposition unit. The exhaust gases emitted are primarily those resulting from the combustion in this unit, with the main emission pollutants being CO, NOX, SO2, and dust. (2) The ammonia distillation off-gases from the *** unit, as well as the extraction off-gases, dehydrated non-condensable gases, distilled non-condensable gases, and catalyst regeneration off-gases from the aniline plant, consist mainly of C, H, and N compounds. These gases are burned in the flares of the aniline plant; the exhaust gases emitted are those resulting from the combustion in these flares, with the main emission components being CO, NOX, SO2, and particulate matter. (3) The waste liquid incinerator located in the aniline plant will emit incineration exhaust gases, with the main emission factors being CO, NOX, SO2, dust, and NH3. (4) The exhaust gas from the MDA production process mainly contains toluene, formaldehyde, aniline, etc. It is sent to an MDA flare for combustion, and the exhaust gases generated from this process have as main emission components CO, NOX, SO2, and dust. (5) The process exhaust gases generated during MDI production, the HCl absorption exhaust gases, and the exhaust gases from the alkali scrubber tower mainly contain CO, phosgene, and chlorobenzene. These gases are sent to an MDI incinerator for destruction, and the exhaust gases resulting from this process contain CO, NOX, SO2, dust, and HCl as the main emission components. (6) The waste gas generated during the MDI prepolymerization process mainly contains CO2, trace amounts of MMDI, and MM103C product; it is discharged after being washed with specialized detergents, with CO2 being the main emission component. (7) Waste gases emitted without organization are primarily treated through nitrogen sealing and the absorption of vent gases from storage tanks; at the same time, their emissions are reduced by improving management and equipment maintenance to ensure that emissions meet the standards set for the factory boundary. In summary, the waste gases generated by the proposed project can be treated using the aforementioned measures to ensure that they are discharged in compliance with regulatory standards. Moreover, according to the prediction results, the maximum ground-level concentrations, hourly average concentration levels, and long-term average concentration levels of the waste gases emitted during normal operation of the project do not exceed the established evaluation criteria; as a result, the functional characteristics of the local air quality environment will not be altered. 2. The generation, treatment, and discharge of wastewater during the operation period of the proposed wastewater treatment project are as follows: (1) The wastewater generated by the project’s recycling system is clean wastewater, which is discharged directly into the park’s clean water pipeline network. (2) The steam condensate from each process is returned to the aniline plant as feedwater for the waste heat boiler, and is not discharged outside. (3) The high-concentration phenol-containing wastewater generated in the neutralization and washing processes of this facility, as well as the alkaline absorption solution produced by the absorption of exhaust gases from this facility, are subjected to pretreatment processes such as stripping, thermal decomposition, and ammonia distillation. After that, these wastewaters are combined with the low-concentration phenol-containing wastewater that has also been treated through stripping and ammonia distillation, and sent to the biochemical pretreatment units within the plant for treatment until they meet the third-level quality standards as well as the requirements for water quality before being discharged into the plant’s sewage treatment plant via the sewage network for further treatment. (4) The brine generated in the neutralization and extraction process of the MDA plant, as well as the flue gas washing water produced by the MDI incinerator, are sent to the brine purification process in the MDA plant for purification; thereafter, they are used as raw materials in the chlor-alkali plant of Chongqing Tianyuan Chemical Co., Ltd. within the industrial park, and are not discharged outside. (5) The regenerated wastewater generated by the mixed-bed demineralization station is acidic or alkaline in nature; after neutralization, it is discharged into the park’s sewage network. (6) During the production process of the proposed project, a small amount of water used for washing equipment floors and wastewater from laboratory analyses will also be generated. The main pollutants are COD and SS, and their concentrations are below the requirements for the water quality entering the park’s sewage treatment plant; therefore, this water can be directly discharged into the park’s sewage network and sent to the sewage treatment plant for treatment until it meets the first-class standards before being released. (7) The main pollutants in the domestic wastewater from employees are COD, NH3-N, SS, etc., and their concentrations are all below the requirements for the water quality entering the park’s sewage treatment plant. Therefore, this wastewater can be directly discharged into the park’s sewage network and sent to the sewage treatment plant for treatment, so as to meet the first-class standards before being released outside. In summary, the drainage system for the proposed project will implement separate treatment for clean and polluted water. The treated water enters the park’s stormwater drainage system through the plant’s clean water pipeline network ； The wastewater is treated to meet the third-level standards on its own, as well as the requirements for water quality entering the park’s wastewater treatment plant; thereafter it enters the park’s wastewater pipeline system. After further treatment at the park’s wastewater treatment plant to reach the first-level standards, it is discharged into the Yangtze River. It will not affect the normal operation of the wastewater treatment plant in the park, nor will it have a significant impact on the Yangtze River, which is the water body receiving the wastewater. 3. The generation, treatment, and discharge of solid waste during the operation period of the proposed solid waste treatment project are as follows: (1) The ammonia distillation waste liquid produced by the ammonia distillation tower in the *** unit’s wastewater treatment process consists mainly of NH3 at about 25%, MNB at less than 0.2%, and water at over 74.8% ； The distillation residue produced by the distillation tower in the aniline plant consists mainly of aniline ； The brine purification waste liquid and regeneration waste liquid generated in the brine purification process of the MDA plant consist, in the former case, mainly of methanol at about 66.5%, aniline at about 0.2%, toluene at about 0.35%, and H2O at about 33%; while the latter consists mainly of H2O at 99.5% and phenol at 0.5%. These waste liquids are incinerated in an incinerator and not discharged outside. (2) The waste catalysts generated by the thermal decomposition flue gas catalytic cracking unit and the hydrogenation reactor of the aniline unit, as well as the waste adsorbents from the brine purification process in the MDA unit, are sent back to the manufacturer for recycling and are not discharged outside. (3) The waste activated carbon generated by the phosgene synthesis tower of the MDA plant, as well as the sludge produced by the biochemical treatment unit, are sent to the Chongqing Solid Waste Treatment Center for disposal and are not discharged outside. (4) The distillation residue generated in the chlorobenzene distillation column of the MDA plant consists mainly of about 60% chlorobenzene and about 40% CCl4 and other chlorinated organic compounds; it is sent to the MDI incinerator for treatment and is not discharged outside. (5) The bottom sludge generated in the tank area is sent to the Chongqing Solid Waste Treatment Center for disposal, and is not discharged outside. (6) The waste gas absorption liquid from the benzene storage tank, whose main components are diesel and benzene, is sent back to the waste liquid incinerator in the plant area for treatment and is not discharged outside. (7) Employees’ domestic waste is collected and disposed of by the local sanitation department, and is not discharged outside. In summary, after being treated with the aforementioned measures, the solid waste generated by the proposed project meets the disposal requirements for general industrial solid waste and hazardous waste, and will not have a significant impact on the local environment. 4. The main sources of noise for the proposed project are cooling towers, refrigerators, compressors, exhaust fans, and high-power pumps; the noise level ranges from 90 to 95 dB(A), and this noise is generated continuously. By implementing measures such as noise suppression, sound insulation, and vibration reduction for noisy equipment, the noise levels in production workshops and work areas can meet the requirements of TJ36-79 \"Hygienic Standards for Industrial Enterprise Design,\" and there will be no noise disturbances to the surrounding community.
