The "12th Five-Year Plan" for the Prevention and Control of Atmospheric Pollution in Key Regions released by China Drying Network News recently pointed out that existing VOC pollution control measures have been difficult to meet the people's urgent requirements for improving air quality. During the period, it is necessary to improve the pollution prevention and control system for volatile organic compounds. On December 17, Zhuang Xiangning, deputy director of the Quality, Safety and Environmental Protection Department of the China Petroleum and Chemical Industry Federation, said in an interview that there is a lot of space for volatile organic compounds in the petroleum and chemical industries. The industry will strengthen the exchange and promotion of emission reduction technologies. , to make efforts to build beautiful China. According to the "Planning", in the next three years, China will conduct targeted investigations on volatile organic compounds in key industries such as petrochemicals, organic chemicals, synthetic materials, chemical drug manufacturing, plastics product manufacturing, and equipment manufacturing painting. Formulate emission factors for volatile organic compounds in various industries, compile emission lists for key industries, understand the distribution characteristics of industries and regions, screen key emission sources, and establish a list of key regulatory enterprises. On this basis, it is necessary to improve the control requirements and policy system for the control of volatile organic compounds in key industries. Formulate emission standards for volatile organic compounds in relevant industries, clean production evaluation index systems, and environmental engineering technical specifications as soon as possible, establish an access system for sales and use of organic solvent products, declare a system for the use of organic solvents, implement VOC content limit management, and explore volatilization Monitoring of organic matter, treatment techniques, and supervision and management mechanisms. For the petrochemical industry, "Planning" specifically proposed that raw materials, intermediate products and finished products should be sealed and stored. The efficiency of the exhaust gas containing volatile organic compounds should not be lower than 90%, and the online continuous emission of volatile organic compounds such as toxic and odorous pollutants should be gradually carried out. Monitoring system construction, isolation measures and prevention and control measures shall be taken between the liquid level of the wastewater collection system and the ambient air. Zhuang Xiangning said: “At present, the emission control system for SO2 and NOx has been established. In the prevention and control of air pollution, it is inevitable that the next step is to control the emission of volatile organic compounds. With the advancement of ecological civilization construction, the more restrictive indicators companies will face. More and more." He told reporters that the petroleum and chemical industry processes are complex and there are many industries involved in the emission of volatile organic compounds, such as oil and gas, coatings, and organic chemicals. Reducing the volatility of organic matter is not only the demand for enterprises to meet the discharge standards, but also the demand for cost reduction and tapping potential. It is also the need to live in harmony with the surrounding residents and to fulfill the corporate social responsibility. Enterprises should take measures to strengthen fine management, and at the same time increase governance, and do a good job of reprocessing after recycling. A staff member of the China National Environmental Monitoring Center told the reporter that China has not yet established a VOC emission standard system, and the base is not clear. There are many kinds of volatile organic compounds and they have a wide range of emissions. At present, the monitoring basis for emissions is still relatively weak. It is a huge system project to establish its pollution prevention and control system. According to the reporter’s understanding, except for the “restrictions on harmful substances in interior decoration materials†and other relevant standards concerning the volatile organic content of coatings, adhesives, and other products, there are basically no volatile organic compounds in the production, storage, and transportation of petroleum and chemical industries. Emissions of national mandatory standards. Ferric Chloride Fecl3,Poly Aluminium Chloride,Fecl3 Cas 7705-08-0 Ferric Chloride Tianjin Centerstar Chemical Co., LTD. , https://www.tccadmixture.com
