According to the environmental impact assessment law and the measures for public participation in environmental impact assessment, Xinxiang Jujing Chemical Co., Ltd. is conducting an environmental impact assessment on the 3000 ton 1,2-pentanediol technical transformation project. In the project demonstration stage, the opinions of individuals and departments related to the project on the construction and environmental protection of the project are solicited. The publicity information of the project is announced as follows:
1、 Project overview
Xinxiang Jujing Chemical Co., Ltd. plans to invest 100 million yuan to build a technical transformation project with an annual output of 3000 tons of 1,2-pentanediol in the existing plant area of Loucun fine chemical new material industry cluster in Xinxiang City, Henan Province. Dismantle the existing triethylenediamine production unit, build a 3000t / a1,2-pentanediol production line in the workshop, and produce aluminum hydroxide powder catalyst in the catalyst workshop for other products. The total construction area of the project is 4000 square meters, mainly including production workshop, rectification tower area, warehouse, raw material storage area, etc. 1,2-pentanediol is obtained by catalytic reaction and alcoholysis with n-pentane as raw material and hydrogen peroxide as oxidant. The project was filed with the development and Reform Commission of Huojia County on June 7, 2021 (project code: 2106-410724-04-01-532557). The project complies with the national industrial policy; In line with the land use planning of the park and the planning EIA and access conditions.
2、 Environmental impact of project construction
1. Environmental impact during construction
The main impacts during the construction period are construction dust, construction equipment noise, a small amount of domestic wastewater and construction wastewater generated during the construction period, and solid waste during the construction period. Environmental protection during the construction period focuses on environmental management. After taking effective measures and strengthening management, the impact of project construction will be effectively controlled. In addition, with the end of the construction period, its impact will disappear.
2. Environmental impact during operation
The main environmental impacts after the operation of the project are: (1) waste gas: the waste gas of the technical transformation and expansion project is mainly the process waste gas in the production of 1,2-pentanediol, the waste gas in the production of catalyst, the waste gas of gas boiler and the waste gas of heat transfer oil furnace; (2) Wastewater: the wastewater of this expansion project mainly includes the process wastewater of the new 1,2-pentanediol unit, the drainage of the circulating cooling water system, the drainage of the new desalted water system and the domestic sewage of the new employees; (3) Solid waste: the solid waste involved in the production process of the project mainly includes distillation residue, waste catalyst and domestic waste; (4) Noise: all kinds of pumps, cooling towers, fans and other high noise equipment.
3、 Key points of environmental protection measures
In view of the environmental impact during the operation period of the project, the project plans to take the following preventive measures:
1. Waste gas: the waste gas of incinerator can meet the standard requirements of hazardous waste incinerator in the environmental protection management opinions of Xinxiang environmental pollution prevention and control office on standardizing the normal operation of incinerator after being treated by SNCR sell out + quench + double alkali desulfurization + wet electrostatic precipitator + activated carbon adsorption; Carbon monoxide can meet the standard requirements of the pollution control standard for hazardous waste incineration (gb18484-2020), and non methane total hydrocarbons can meet the standard requirements of the notice on the recommended emission value in the special treatment of volatile organic compounds in industrial enterprises in the province (Yuhuan Gongjian ban (2017) No. 162); After treatment, incinerator waste gas can be discharged in a long-term and stable manner; After the process waste gas is treated by condensation + RTO unit, the total non methane hydrocarbon and methanol can meet the standard requirements of the notice on the recommended emission value in the special treatment of volatile organic compounds in industrial enterprises in the province (yhzb (2017) No. 162); Nitrogen oxides can meet the standard requirements of incinerators in the environmental protection management opinions of Xinxiang environmental pollution prevention and control office on standardizing the normal operation of incinerators; After three-stage alkali absorption treatment, the nitrogen oxides of roaster waste gas can meet the requirements of emission standard of air pollutants for industrial kilns (db41 / 1066-2020); The existing gas-fired boiler and heat-conducting oil furnace have completed the low nitrogen transformation, and the discharged waste gas can meet the requirements of the notice of Xinxiang environmental pollution prevention and control headquarters office on accelerating the low nitrogen transformation of gas-fired boiler (Xinhuan Gongjian Office (2019) No. 25) and the requirements of Table 1 air pollutant emission limit of gas-fired boiler in the emission standard of boiler air pollutants (db41 / 2089-2021).
2. Wastewater: after the wastewater of the expansion project is treated by the sewage treatment station in the plant, the general outlet of the plant can meet the requirements of the indirect discharge standard of water pollutants in chemical industry (db41 / 1135-2016) and the inlet water quality of the sewage treatment plant in Xinxiang Loucun fine chemical new materials industrial Park.
3. Solid waste: the solid waste involved in the production process of the project mainly includes distillation residue, waste catalyst and domestic waste, of which distillation residue belongs to hazardous solid waste. The distillation residue is sent to the hazardous waste incinerator for disposal, and the waste catalyst is stored in the hazardous waste temporary storage room and sent to the roaster for activation and reuse. Domestic garbage shall be cleared and transported by the municipal environmental sanitation department. The temporary storage of hazardous waste depends on the existing temporary storage room of hazardous waste.
4. Noise: for the high-noise equipment of the project, the standard emission can be achieved after taking measures such as foundation damping, sound insulation and noise elimination, with little impact on the surrounding environment.
