On March 26, 2015, Sinopec announced that it will launch a large-scale charity operation of “Clear Water and Blue Skyâ€. It will add a total of 8,000 tons of diesel vehicles with a capacity of approximately 800,000 barrels and a value of 40 million yuan to diesel vehicles of the National IV and above. Tail gas treatment liquid to encourage diesel vehicles to accelerate the pace of upgrading. It is reported that Sinopec will replenish diesel vehicle tail gas treatment fluids for heavy-duty diesel vehicles equipped with SCR systems in 5,000 Sinopec gas stations all over the country, in order to guide the society to pay attention to diesel vehicle emission reduction problems, encourage the acceleration of diesel vehicles, and promote the use of diesel vehicles. Heavy-duty diesel vehicles and associated tail gas treatment liquids discharged from the State 4 or above. Sinopec refueled heavy-duty diesel vehicles equipped with SCR systems with diesel vehicle tail gas treatment fluids to guide the society to pay attention to diesel vehicle emission reduction problems, encourage the acceleration of diesel vehicle upgrades, and promote the use of heavy-duty diesel vehicles and associated exhaust gas discharged from the country and above. Treatment solution. Emissions from heavy-duty diesel vehicles are a top priority for motor vehicle management. According to the “Annual Report of China’s Motor Vehicle Pollution Prevention and Control (2013)†issued by the Ministry of Environmental Protection, heavy-duty diesel vehicles only account for 5.6% of vehicle ownership, but their nitrogen oxides (NOX) and particulate matter (PM) emissions account for 67.7% of total vehicle emissions. And 78%. In other words, heavy-duty diesel vehicles are the major sources of emissions of NOX and PM in motor vehicles. According to the announcement of the Ministry of Industry and Information Technology, since January 1, 2015, new production and sales of heavy-duty diesel vehicles must meet the National IV emission standards. However, at present, the elimination of diesel vehicles in the third and the following countries is too slow, and the proportion in the fourth or above countries is very low. To meet this standard, heavy-duty diesel vehicles are based on the upgrade of the engine, the world has two main technical routes, one is the selective catalytic reduction technology (SCR), the second is the exhaust gas recirculation + particulate trap (EGR + DPF) . The advantage of SCR is that the PM is burned in the engine through high temperature and high pressure, and then the NOX is solved through the diesel exhaust gas treatment liquid. It also has the characteristics of improving fuel economy, and is the main technical route selected by the automobile manufacturers in China. Lv Dapeng, a spokesperson for Sinopec, said that the pollution of heavy-duty diesel vehicle exhaust emissions is particularly serious in motor vehicles. Accelerated treatment is an urgent task. The diesel engine of the National IV emission standard upgraded the engine and adopted the "revolutionary" technology of SCR. It is of special significance to reduce vehicle exhaust pollution. If the country’s three-and-form diesel vehicles were “iron pots and stir-friesâ€, then the lids would be tightly closed and “oil fumes†would be emitted, ie exhaust pollution. The diesel engine that meets the national IV or above emission standard takes another route. Like the “pressure cookerâ€, the two main pollutants—PM is eliminated in the engine through “high temperature and high pressureâ€, while the NOX is passed through the diesel. The reduction treatment of tail gas treatment liquid can realize harmlessness and reach the fourth national or even national five emission standards. Qiao Yingbin, a senior chemical expert who has long been engaged in the study of exhaust gas treatment fluids for diesel vehicles, urged the use of policies to encourage diesel vehicles to upgrade. He said that the NOX emissions of the National IV heavy-duty diesel vehicles were lower by 30% than the National III heavy-duty diesel vehicles, and PM was reduced by 80%. However, at present, the proportion of national four-vehicle vehicles is still very low. It is necessary to study and formulate the national IV heavy-duty diesel vehicle replacement subsidy policy, accelerate the elimination of old diesel vehicles, and drastically reduce exhaust pollution of diesel vehicles. At the same time, it urges related companies to do a good job in the production and supply of diesel vehicle exhaust gas treatment fluids, and to guide and standardize the use of treatment fluids. The book “Quality Questions on Diesel Vehicle Exhaust Gas Solutions†published by China Business Press lists three major benefits of installing an SCR system and a diesel vehicle tail gas treatment solution: First, particulate matter emissions can be greatly reduced to meet the national IV. Emission standards; Second, 80% of the nitrogen oxides in the exhaust can be converted to nitrogen, which can fully meet the national IV or even national five emission standards. Third, high-temperature combustion inside the engine improves the fuel economy of the engine. , can reduce fuel consumption by 5%-7%. For example, a heavy-duty diesel vehicle (with a fuel consumption of 35 liters per hundred kilometers) running 200,000 kilometers can recover the installation cost of the SCR system. The fuel-saving cost is greater than the cost of the exhaust gas treatment fluid for a diesel vehicle. Diesel exhaust gas treatment liquid is an essential product to meet the national IV emission standards. When a heavy-duty diesel vehicle equipped with an SCR system is running, diesel exhaust gas treatment fluid must be added at the same time. It is an essential product to solve nitrogen oxides and treat heavy-duty diesel vehicle exhaust emissions to meet the national IV emission standards. China's release of the five oil product standards in 2013 requires that it be fully implemented nationwide from January 1, 2018. The limits for the new standard's sulfur content index have been reduced from 50 ppm in the fourth phase to 10 ppm, a reduction of 80%, exceeding the corresponding standards in the United States, and the main indicators are equivalent to the current European standards, reaching the highest international level. Sinopec has supplied five oil products to eight cities in Beijing in 2012, eight cities in Shanghai and Jiangsu in the same year, and four oil and gas products in eight provinces and cities in Guangdong, Shaanxi, Zhejiang, Hangzhou, Jiaxing, Tianjin, Hubei and Wuhan in 2014. In the future, Sinopec will invest 30 billion yuan each year to upgrade and provide more quality resources to the society and reduce environmental pollution. The "Clear Water Blue Sky" environmental protection plan will invest 22.87 billion yuan in 803 projects over a three-year period. This is the largest environmental protection operation in the history of Sinopec, and it is also the most intensive and most involved special environmental protection operation for Chinese enterprises so far. In 2014, Sinopec had invested 11.57 billion yuan, and carried out 533 environmental remediation projects, which accounted for 52.9% and 71.7% of the total investment respectively, and produced good social and environmental effects.
