On March 26, 2015, Sinopec announced that it will launch a large-scale public welfare operation of “Blue Sky and Blue Skyâ€, which will provide a total of 8,000 tons, about 800,000 barrels and a diesel vehicle worth 40 million yuan for the national heavy duty diesel vehicles of the national fourth and above. Exhaust gas treatment liquid to encourage diesel vehicles to speed up the pace of upgrading.
It is reported that Sinopec will freely add diesel exhaust gas treatment liquids to heavy-duty diesel vehicles equipped with SCR systems in 5,000 Sinopec gas stations throughout the country to guide the society to pay attention to diesel vehicle emission reduction problems, encourage diesel vehicles to accelerate the pace of upgrading, and promote the use of Heavy-duty diesel vehicles and associated exhaust gas treatment fluids discharged from China's fourth and above.
Sinopec freely injects diesel exhaust gas treatment liquid for heavy-duty diesel vehicles equipped with SCR system to guide the society to pay attention to diesel vehicle emission reduction, encourage diesel vehicles to accelerate the pace of upgrading, and promote the use of heavy-duty diesel vehicles and supporting exhaust gas discharged from the country 4 and above. Treatment fluid.
Heavy diesel vehicle emissions are the top priority of motor vehicle management. The Ministry of Environmental Protection's "China Motor Vehicle Pollution Prevention and Control Annual Report (2013)" shows that heavy-duty diesel vehicles account for only 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%. That is to say, heavy-duty diesel vehicles are the main source of NOX and PM emissions in motor vehicles.
According to the announcement of the Ministry of Industry and Information Technology, since January 1, 2015, the newly produced and sold heavy-duty diesel vehicles must meet the national four emission standards. However, the current elimination of diesel vehicles in the third and third countries is too slow, and the proportion of the national four and above is very low. In order to meet this standard, heavy-duty diesel vehicles are based on upgrading engines. There are two main technical routes in the world. One is selective catalytic reduction (SCR) and the other is exhaust gas recirculation particulate trap (EGR DPF). The advantage of SCR is that it first eliminates PM combustion through high temperature and high pressure in the engine, and then solves NOX through diesel exhaust gas treatment liquid. It also has the characteristics of improving fuel economy, and is the main technical route selected by automobile manufacturers in China.
Lu Dapeng, a spokesman for Sinopec, said that heavy-duty diesel exhaust emissions are particularly serious in motor vehicles, and speeding up governance is a top priority. The diesel engine of the National IV emission standard upgraded the engine and adopted the "revolutionary" technology of SCR. It is especially important for reducing vehicle exhaust pollution. If the third and previous diesel cars are "iron pan cooking", then the cover will be tightly closed, and there will also be "smoke", that is, exhaust gas pollution. The diesel engine that meets the national and above emission standards is another route. Just like the “pressure cookerâ€, the two main pollutants – PM is eliminated in the engine through “high temperature and high pressureâ€, while NOX passes diesel. The vehicle tail gas treatment liquid reduction treatment can achieve harmlessness and reach the national four or even national five emission standards.
Qiao Yingbin, a senior chemical expert who has been engaged in research on diesel exhaust gas treatment for a long time, called for the use of policies to encourage diesel vehicles to speed up the upgrade. He said that the NOX emissions of the national four heavy-duty diesel vehicles are 30% lower than the national three heavy-duty diesel vehicles, and the PM is reduced by 80%. However, at present, the proportion of the country's four cars is still very low. It is necessary to study and formulate the subsidy policy for the replacement of the national heavy-duty diesel vehicles, accelerate the elimination of old diesel vehicles, and significantly reduce the pollution of diesel vehicles. At the same time, the relevant enterprises are urged to do a good job in the production and supply of diesel exhaust gas treatment liquid, and to guide and standardize the use of the treatment liquid.
The book “Drug Vehicle Exhaust Gas Treatment Solution†published by China Business Press lists three major benefits of installing SCR system and diesel exhaust gas treatment solution: First, particulate matter emissions can be greatly reduced to meet the national four. Emission standards; second, 80% of the nitrogen oxides in the exhaust gas can be converted into nitrogen, which can fully meet the national four or even national five emission standards; third, high-temperature combustion inside the engine, improving the fuel economy of the engine, compared with the national three cars Can reduce fuel consumption by 5%-7%. For example, a heavy-duty diesel vehicle (with a fuel consumption of 35 liters per 100 kilometers) can recover the installation cost of the SCR system after running 200,000 kilometers. The fuel-saving cost is greater than the cost of the diesel exhaust gas treatment liquid.
Diesel exhaust gas treatment liquid is a must-have for meeting the national four emission standards. When a heavy-duty diesel vehicle equipped with an SCR system is driven, it must be filled with diesel exhaust gas treatment liquid. It is a must-have for solving nitrogen oxides, treating exhaust emissions from heavy-duty diesel vehicles, and meeting the national emission standards.
China issued the National Five Oil Standards in 2013, requiring full implementation nationwide from January 1, 2018. The new standard's sulfur content index limit is reduced from 50 ppm in the fourth stage to 10 ppm, which is 80% lower. It exceeds the corresponding standards in the United States, and the main indicators are equivalent to the current European standards, reaching the highest level in the world. Sinopec has supplied it to Beijing, 2013 to Shanghai and Jiangsu along the Yangtze River in 2014. In 2014, it supplied five oil products to eight provinces and cities including Guangdong, Shaanxi, Hangzhou Hangjiahu, Tianjin and Hubei. In the future, Sinopec will invest 30 billion yuan each year to upgrade and provide more high-quality resources for the society and reduce environmental pollution.
The “Clear Water Blue Sky†environmental protection plan will invest 22.87 billion yuan in 803 projects in three years. This is the largest environmental protection action in the history of Sinopec, and it is also the one-time investment and the most extensive environmental protection special action by Chinese companies. In 2014, Sinopec invested 11.57 billion yuan and carried out 533 environmental governance projects, accounting for 52.9% and 71.7% of the total investment, respectively, resulting in better social and environmental effects.
