volatile organic compounds (VOCs) emissions in the petrochemical and chemical industries face the strongest "hoop curse". At the executive meeting of the Ministry of environmental protection held a few days ago, the work plan for the prevention and control of volatile organic compounds pollution during the 13th five year plan was reviewed and approved in principle

the plan puts forward clear emission reduction targets for the petrochemical and chemical industry: it requires that VOCs emissions from the petroleum refining and petrochemical industries be reduced by more than 40% by 2020; VOCs emissions from chemical industries such as pesticides, pharmaceuticals, synthetic resins, rubber and plastic products manufacturing will be reduced by more than 30%. 250 oil refining enterprises with a total refining capacity of 710 million tons have completed VOCs control in strict accordance with the requirements of pollutant discharge permit management, and 7100 pharmaceutical enterprises and 2000 pesticide enterprises have completed VOCs control tasks

as a "major player" in VOCs control, the plan requires to comprehensively promote VOCs control in petroleum refining and petrochemical industries, as well as chemical industries such as pesticides, pharmaceuticals, synthetic resins, rubber, plastic products manufacturing, and new coal chemical industry. Strengthen refined management, implement the pollutant discharge permit system, and promote the transformation and upgrading of the industry through comprehensive measures such as source prevention, process control and end treatment, so as to achieve up to standard emissions. Promote raw and auxiliary materials and products with low VOCs content and low reactivity. Focus on reducing the use of solvents and additives such as benzene, toluene, xylene and dimethylformamide, and implement raw material substitution. The pesticide industry should speed up the replacement of solvents such as light aromatics, vigorously promote water-based solvents, and strictly control the use of organic solvents

Ning Miao, director of the comprehensive atmospheric Planning Office of the Environmental Planning Institute of the Ministry of environmental protection, who participated in the formulation of the plan, said: "The petroleum and chemical industry should actively implement industrial restructuring, ban illegal 'scattered and poor' enterprises, focus on coating, rubber products, chemical fiber production and other enterprises, strictly enforce the access of construction projects, and implement staggered peak production. At the same time, we should also focus on the dynamic and static sealing points of equipment, storage, loading and unloading, waste water system, organized process waste gas and abnormal working conditions and other source items, such as pharmaceuticals, pesticides, coking, coatings, adhesives Dye and other industries gradually carry out leakage detection and repair (LDAR). "

luanzhiqiang, vice chairman of the waste gas purification Committee of the China Environmental Protection Industry Association, said: "in the future, VOCs control in chemical industry parks will also become an important task for the industry. With all regions vigorously promoting the entry of evolutionary enterprises into the park, all kinds of chemical parks and manufacturing Parks will also be areas where VOCs control is concentrated, and the improvement of the concentration of chemical enterprises also creates conditions for the unified management of VOCs and pollution control. Previously, Jiangsu Province has issued The action implementation plan for small body parts of the special volatile organic compounds pollution control clearly requires that the comprehensive treatment of VOCs in 52 chemical parks be completed by the end of 2017 compared with glass fiber composites. "

vocs are important precursors for the formation of ozone and fine particulate pollution, and also have an important impact on the formation of secondary PM2.5. In the composition of VOCs emissions from anthropogenic sources, industrial sources, transportation sources, domestic sources and agricultural sources account for 43%, 28%, 15% and 14% respectively. Among the industrial sources, petrochemical industry, chemical industry, industrial coating and packaging and printing are the main industries to solve the problem of "not using good materials", accounting for about 70% of the emissions

emission control tasks in the petroleum and chemical industry

● comprehensively promote VOCs control. By 2020, VOCs emissions from petroleum refining and petrochemical industries will be reduced by more than 40%, and VOCs emissions from chemical industries such as pesticides, pharmaceuticals, synthetic resins, rubber and plastic products manufacturing will be reduced by more than 30%

● promote raw and auxiliary materials and products with low VOCs content and low reactivity, focus on reducing the use of solvents and additives such as benzene, toluene, xylene and dimethylformamide, and implement raw material substitution

● optimize the production process, adopt closed production process, and promote the use of leak free and low leakage equipment

● comprehensively promote leakage detection and repair (LDAR). Enterprises should establish LDAR management system and information management platform to continue to promote LDAR work

● strictly control storage and handling losses

● strengthen the collection and treatment of fugitive waste gas such as wastewater treatment system

● strengthen the treatment of organized process waste gas, and give priority to the recycling of process waste gas containing high concentration VOCs, such as process purge gas and sour water tank process tail gas
