The four major occupational standards for waste gas treatment are facing transformation:

In 2016, the Ministry of Environmental Protection issued a total of 58 national regulations, including 33 monitoring specifications and method specifications, 7 environmental specifications product skill requirements, 6 pollutant emission standards, 4 environmental testing skills specifications, and 3 environmental assessments. Skills guide, 2 environmental protection engineering skills specifications and 3 other environmental regulations. Six of the 58 specifications are pollutant discharge regulations and will be implemented after 2017. Along with this, five specifications in the 2015 release will be fully implemented in 2017. Let us look at what impact these 11 specifications will have on the profession in the future?

Exhaust gas treatment specifications:

Oil/petrochemical occupation

New VOCs, NOx and benzene, toluene and other waste gas treatment regulations will be fully implemented, and the technical transformation will drive nearly 200 billion yuan in shopping malls.

The petroleum refining, petrochemical and synthetic resin industries have long fulfilled the inductive emission standards. With the continuous improvement of China's crude oil processing capacity, occupational pollutant emissions are high, and regional air and water pollution problems are becoming more and more obvious. To this end, the Ministry of Environmental Protection announced in 2015 the "Specifications for Pollutant Discharge of Petroleum Refining Industry" (GB31570-2015), "Specifications for Pollutant Discharge of Petrochemical Industry" (GB31571-2015), "Specifications for Pollutant Discharge of Synthetic Resin Industry" (GB31572-2015) 3 petroleum/petrochemical occupational industrial pollutant discharge regulations, and existing enterprises need to fully implement the new standard from July 1, 2017.

Overall, the new standard further clarifies the types of pollutants that should be handled by the petroleum refining and chemical industries. It not only severely tightens the conventional water pollutants such as COD and ammonia nitrogen, but also limits the emission of atmospheric pollutants such as SO2, PM and NOx. Values, as well as new pollutant discharge limits such as TN and TP, as well as special emission limits for pollutants in environmentally sensitive areas. Along with this, for the non-point source pollution, the new specification has increased the VOCs (Volatile Organic Pollutants) process in 10 aspects such as organic liquid storage tanks, wastewater collection and treatment systems, equipment leak detection and repair, torch, inspection and maintenance, and sampling. Emission control requirements.

The Petroleum Refining Industry Pollutant Discharge Regulations and the Petrochemical Industry Pollutant Emissions Regulations also set emission limits for non-methane total hydrocarbons in wastewater treatment, organic waste gas control equipment discharges, and characteristic organic pollutants such as benzene and toluene. . The “Specifications for Pollutant Emissions from the Petroleum Refining Industry” increases the emission limits of seven characteristic organic pollutants such as benzene and toluene in wastewater, and is directed to the catalytic cracking regeneration flue gas, process furnace flue gas and acidity unique to the petroleum refining industry. The gas recovery tail gas proposes a pollutant discharge limit. The “Specifications for Pollutant Emissions from the Petrochemical Industry” increases the emission limits of 60 characteristic organic pollutants such as benzene and toluene in wastewater, and proposes pollutant emission limits for the recovery of tail gas from halogenated hydrocarbons unique to the petrochemical industry.

Petroleum refining and new VOCs, NOx, benzene, toluene and other pollutants control, technical transformation led to 85.6 billion yuan shopping mall demand

According to estimates, after the implementation of the "Specifications for Pollutant Emissions from the Petroleum Refining Industry", the emission reductions of SO2, NOx, VOCs, COD, and ammonia nitrogen are 320,000 tons, 50,000 tons, 1.2 million tons, 30,000 tons, and 8,000 tons. To this end, all domestic refining companies will increase environmental protection investment by about 85.6 billion yuan. In the meantime, about 3.2 billion yuan was invested in the catalytic cracking flue gas desulfurization system, about 2 billion yuan in the sulfur tail gas purification system, and about 17.4 billion yuan in the desulfurization of the process heating furnace fuel gas. The replacement of the process heating furnace low nitrogen incinerator requires about 3 billion yuan to carry out the catalysis. Cracking flue gas denitrification and adopting advanced catalysts with low nitrogen oxide emission skills will cost about 20 billion yuan. The implementation of catalytic incineration, adsorption, absorption and other non-methane total hydrocarbons will cost about 20 billion yuan to carry out sewage treatment plant transformation and water saving. The transformation needs to invest 20 billion yuan.

Petrochemicals added more than 60 pollutants such as VOCs, benzene and toluene to control emissions, and technological transformation led to a demand of 47.5 billion yuan in shopping malls.

The implementation of the "Specifications for Pollutant Discharge of Petrochemical Industry" (GB31571-2015), SO2, NOx, VOCs, COD, ammonia nitrogen will be reduced by 200,000 tons, 50,000 tons, 1.5 million tons, 150,000 tons and 24,000 tons. The corresponding environmental protection contribution is about 47.5 billion yuan. The new standard adopts the dual control of the total discharge of sewage, which requires the existing petrochemical enterprises to carry out useful skill transformation, reduce the concentration of pollution factors, reduce the discharge of sewage, and it is necessary to build exhaust gas treatment equipment. And the effect is necessary to reach the requirements of the normative rules, such as the selection of adsorption skills, if the first-level adsorption is not up to standard, you can use the secondary adsorption skills or use a variety of skills to summarize the application methods to reach the specification requirements.

The implementation of the "Specifications for the Export of Synthetic Resin Industrial Pollutants" will achieve an annual COD reduction of 5,8006,000 tons, and the annual reduction of VOCs in the exhaust gas will be about 2,300-4,000 tons / year. In order to achieve this policy, synthetic resin industry producers need to improve the advanced technology of production technology and equipment, reach the intention of improving the conversion rate of materials and reduce pollution emissions. Together, we must improve environmental protection equipment and improve processing power. The synthetic resin wastewater treatment method that does not occur in process wastewater can use biochemical or physicochemical-biochemical combination skills. If process wastewater occurs, it is required to use incineration, evaporation, condensation + adsorption, delayed condensation-biochemistry and other skills as supporting skills. In terms of waste gas treatment, the treatment methods such as incineration, adsorption, condensation and adsorption are the first choices. To this end, the environmental protection investment will be about 26.5 billion yuan.

Chemical manufacturing

Technical transformation drives nearly 30 billion shopping malls

In 2016, the Ministry of Environmental Protection announced the “Regulations on Industrial Emissions of Caustic Soda and Polyvinyl Chloride” (GB15581-2016). The new caustic soda and PVC industrial enterprises have fulfilled the new regulations since September 1, 2016. The existing enterprises are in 2018. Performed on July 1. Together, the “Inorganic Chemical Industry Pollutant Discharge Regulations” (GB31573-2015) promulgated in 2015 will also be fully implemented on July 1, 2017.

The new regulations further tightened the limits of pollutant discharge concentration limits, added new pollutants such as total phosphorus and total nitrogen, and made special rules for the maximum emission concentration of wastewater and exhaust pollutants in key areas. The "Inorganic Chemical Industry Pollutant Discharge Regulations" also added occupation-specific emission limits for heavy metals, radioactive elements and some characteristic pollutants; "Caline and Polyvinyl Chloride Industrial Pollutant Discharge Regulations" for non-methane total hydrocarbons per unit of product Emissions and baseline displacements are rules.

After the implementation of the "Inorganic Chemical Industry Pollutant Discharge Regulations", it is expected that the emissions of ammonia nitrogen, COD and total lead will be reduced by 71.1%, 77% and 66.7% compared with the current implementation; the particulate matter and SO2 emissions will be reduced by 89.5%. 71%, and can be used to control the emission of heavy metals and toxic and harmful pollutants such as chlorine, fluorine, arsenic, cyanide, ammonia and sulfide. After the implementation of this standard, it is estimated that the fixed investment for new enterprises will be about 159.2~21 billion yuan, and the annual operating cost will be about 11.2~1.6 billion yuan.

After the implementation of the "Calcium and Polyvinyl Chloride Industrial Pollutant Discharge Regulations", the annual emissions of CODcr, BOD5, total mercury and vinyl chloride will be reduced by 77%, 67%, 67% and 87%, particulate matter, vinyl chloride, Annual emissions of non-methane total hydrocarbons will be reduced by 51%, 72%, and 58%. The total investment in environmental protection equipment will be about 4.6 billion yuan, and the annual operating cost will be about 600 million yuan. During this period, the total sewage treatment equipment will be about 2.2 billion yuan, and the annual operating cost will be 400 million yuan.

The new regulations put forward clear emission control requirements and time limits for the inorganic chemical industry, caustic soda and polyvinyl chloride industry. In order to reach such an emission standard, enterprises can increase their environmental protection equipment and strengthen corresponding handling methods, etc., and strive to reach within the time limit. requirements.

Recycling non-ferrous metal occupation:

New technical standards for emission reductions such as dioxin, arsenic, antimony and chromium have boosted demand for shopping malls by 2.3 billion yuan

Since the beginning of the new century, China's recycling of non-ferrous metals (primarily copper, aluminum, lead, zinc four major varieties) industry continues to develop rapidly, industrial planning continues to expand, becoming an important part of China's non-ferrous metals, but the development of the profession also brings intolerance Neglected environmental issues. According to the estimation of the Ministry of Environmental Protection, the total emissions of SO2, PM and COD from the primary (characteristic) air pollutants in China's primary renewable non-ferrous metals industry in 2012 were 12,248 tons, 3,092 tons and 665.2 tons, and the total wastewater was 8.69 million tons. Prior to the publication of the new regulations in 2015, the regenerative non-ferrous metal occupations were fulfilled by the “Sewage Induction Emissions Regulations (GB89781996)”, “Insulated Pollutants Inductive Emissions Regulations (GB16297-1996)”, and “Industrial Kiln Air Pollutant Emissions Regulations (GB9078). -1996))", most emission limits have not met the advanced environmental requirements. Under this scenario, in 2015, the Ministry of Environmental Protection drafted and promulgated the “Regulations on Pollutant Discharge of Recycled Copper, Aluminum, Lead and Zinc Industry” (GB31574-2015), requiring existing enterprises to implement the specification from January 1, 2017.

The new specification has improved the pollutant discharge control requirements in many ways:

In terms of pollutant emission limits, the specification imposes limits on 17 pollutant targets in water and 13 pollutant targets in the atmosphere. CODcr, SS, ammonia nitrogen and heavy metal pollutants are all large in water pollutants. The target is tightened to the target limit; the emission limits of PM, SO2 and sulfuric acid in atmospheric pollutants are separated from 200mg/m3 (secondary specification), 1430mg/m3 (secondary specification), 45mg/m3 to 30mg/m3, 150mg. /m3, 20mg/m3; increased emission limit requirements for dioxins, arsenic, antimony and chromium;

The baseline displacement and the reference displacement are set, and the pollutant discharge concentration and the total discharge amount are controlled in both directions. If the baseline displacement and the reference displacement requirement are not met, the baseline emission mass concentration needs to be converted.

After fully implementing the new regulations, the characteristic pollutants emitted by China's recycled copper, recycled aluminum, recycled lead and recycled zinc industries will be greatly reduced. The annual reduction rates of PM, SO2, dioxin and COD are 64% and 41%, respectively. 45% and 39%. After the implementation of the standard, the amount of environmental protection equipment that needs to be rebuilt or newly built in the non-ferrous metal recycling industry will be about 1.8 billion yuan, and the annual operating cost will be about 450 million yuan.

In recent years, some large-scale recycled non-ferrous metal enterprises have increased environmental awareness and improved pollutant discharge, but there is still a long way to go from the new specification limits. This type of enterprise has made a large part of the production equipment and environmental protection equipment. Renovation and upgrading, strengthen production and processing, can reach the pollutant discharge requirements in the new regulations; most of the SMEs change their thinking, increase environmental protection investment, revolutionize the entire production process and environmental protection equipment, and then reach new Standardize environmental protection requirements. For those enterprises that have long been not paying attention to environmental protection or poor operation and are unable to make environmental protection investment, they will bear greater environmental pressure. After the new regulations are fully implemented, and the severe new environmental protection law is expected, it will be accelerated. Screening a large number of recycled non-ferrous metals enterprises that are unable to carry out the upgrading.

As an environmental management method, pollutant discharge regulations have been changed from pollutant emission reduction to industrial structure optimization and improvement of environmental quality results, and have become an important means and method for industrial transformation. During the “Thirteenth Five-Year Plan” period, the implementation of 11 new regulations will further accelerate the screening of backward production capacity and the pace of annexation and reorganization among enterprises, and promote a group of enterprises with backward production, high resource and energy consumption, serious environmental pollution, and small and weak enterprises. Screening out, together with the promotion of refinery, petrochemical and other professional economic restructuring and economic growth method changes, and promote industrial production technology and pollution management skills progress has positive significance.

Mobile pollution source:

By the end of 2015, the number of motor vehicles in the country reached 279 million, with 165,900 ships on the water. The environmental pollution caused by the use of motor vehicles and the delivery of exhaust emissions from ships has become increasingly prominent. In 2016, the Ministry of Environmental Protection issued five mobile pollution source pollutant discharge regulations for motorcycles, mopeds, light cars, light hybrid electric cars and vessels, which are separate from the "Motorcycle pollutant emission limits and measurement methods (China's first Four stages) (GB14622-2016), "Motorcycle pollutant emission limits and measurement methods (China's fourth stage)" (GB18176-2016), "light car pollutant emission limits and measurement methods (China's sixth Stage)" (GB18352.6-2016), "Light Mixing Electric Vehicles Pollutant Emission Control Requirements and Measurement Methods" (GB19755-2016), "Vehicle Engine Exhaust Pollutant Emission Limits and Measurement Methods (China's top and second Phase) (GB15097-2016), this is also the first national regulation of China's air pollutant discharge control. Together, the “Limited Pollutant Emission Limits and Measurement Methods for Light Cars (China's Fifth Phase)” (GB18352.5—2013), which was released in 2013, will also be fully implemented on January 1, 2018.

The new release and implementation of the mobile pollution source pollutant discharge specifications are newer than the original specification for the PM pollution control requirements, and proposed (ships) and further tightened (motor vehicles) THC, CO, NOx and other pollutant discharge limits. In terms of environmental protection, increase the emission control key component inspection requirements, improve production consistency, check the determination procedures, and add (motorcycle) and tightened (sedans) on-board diagnostic system (OBD) control requirements. In addition, the "Light Vehicle Pollutant Limits and Measurement Methods (China's Sixth Phase)" also added actual road travel emission requirements and tightened the evaporation control requirements and test requirements; "Light hybrid electric car pollutant emission control The Requirements and Measurement Method (GB19755-2016) adds a new test method to the hybrid electric car that can be externally charged.

According to estimates, if the motorcycle's national standard implementation period is calculated according to three years, all motorcycles newly produced during the period will have a total emission reduction of about 6.5 million over the entire service life of the current standard pollutants CO, HC and NOx emissions. Tons, 2 million tons and 300,000 tons; after implementing the light vehicle standard 5, the annual emission reductions of CO, HC and NOx will be 600,000 tons, 60,000 tons and 48,000 tons; if further implementation of the light vehicle On this basis, the cumulative reduction of pollutants CO, THC, NOx, and PM emissions was 95.55 million tons, 2.535 million tons, 495,000 tons, and 30,000 tons. The implementation of the first phase of the ship's specification list was implemented for three years. The total reduction of NOx and PM emissions during the life of the vessel (according to 25 years) will be 1.44 million tons and 389,000 tons. If the second stage specification is implemented, it will be at this end. It will reduce 1.15 million tons and 58,000 tons.

It can be seen that the environmental benefits of the implementation of the new norms are very obvious. The new specification is primarily aimed at new stereotypes and new production of motorcycles, cars and marine engines. The intention is to control the increase of pollutant emissions from the source, reduce the pollutant emissions of new vehicles, and design new and new vehicles. Propose more strict
