From March 1st, Beijing will use the Beijing-Six standard gasoline and diesel. This standard is called the most stringent emission standard in history. Beijing is the first in the country to enter the sixth phase of the automotive oil standard era.
　　 According to the data from the Beijing Municipal Environmental Protection Bureau, the technical indicators of the Beijing Six Standards refer to the most stringent automotive fuel standards in the world. The sulfur content remains unchanged, and the olefins, aromatic hydrocarbons, benzene, vapor pressure and distillation range in gasoline are further tightened. And major environmental indicators such as polycyclic aromatic hydrocarbons, density, flash point, and detergent in diesel. China Petroleum (601857, shares it) North China Petrochemical experts said: "The new standard for oil products excellence, compared with the current national five standard, the olefin, aromatics content limit can be said to be a cliff-type reduction."
According to industry insiders who have participated in the formulation of the Beijing Sixth Standard, the Beijing Sixth Standard is known as the “most stringent emission standard in historyâ€. In addition to the more widely known Euro VI standards, it also refers to the more stringent California standards. .
According to the statistics of the Beijing Municipal Environmental Protection Department, it is estimated that after the use of Jingliu oil products, the emission of particulate matter in gasoline vehicles will be reduced by 10%, and the non-methane organic gases and nitrogen oxides will be reduced by 8% to 12%. Oxides decreased by 4.6% and particulate matter by 9.1%. In the Jing Six era, less and less blue became more predictable.
Why does the sulfur content remain the same?
The reason why the sulfur content of the Jingliu standard remains unchanged is because the current sulfur content of the national five standard has been less than 10ppm (parts per million concentration), the sulfur reduction space is extremely narrow, and then the high cost desulfurization is used to improve the environment. The meaning of quality is not great.
In fact, since the lead-free in 2002, the main tone of domestic oil upgrades has been to reduce sulfur. Cao Xianghong, chairman of the Standardization Management Committee of the "Petroleum Products and Lubricants" sub-labeling committee and academician of the Chinese Academy of Engineering, said that the current gasoline and diesel oils have been ultra-low sulfurized, and the sulfur content has been reduced from the past 2000ppm, 500ppm, 350ppm to the national four. 50ppm, 10ppm of the country's five, "decline speed, unprecedented range."
The reporter learned that since the implementation of light vehicle pollutant emission standards in China since 2000, the national standard has been consistent with the world's highest standard European standard. Compared with the European standard, the national standard and the European standard have the same sulfur and benzene content limits; but the olefin and aromatic content There are still some gaps in the limits. Therefore, after ultra-low vulcanization, the main focus of this standard revision is on the reduction of olefins, aromatics and other particulate matter impact factors.
Bringing unprecedented technical challenges to refining and chemical companies
The official website of the Beijing Municipal Environmental Protection Bureau outlines the “Big Highlights†of Jingliu Oil Products, which aims to reduce volatile organic compounds (VOC) emissions. The tightening of this indicator will help reduce atmospheric oxidation and reduce PM2.5 formation and ozone generation.
But the technical challenges brought to refining and chemical companies are unprecedented. Sinopec (600028, shares it) Yanshan Petrochemical senior expert Song Yichang concluded, "the increase in device constraint variables, the difficulty of refining refined oil products", refined oil reconciliation mainly through isomerization, alkylation means, involving a series of complex processes and funds Invest. Last year alone, Yanshan Petrochemical invested more than 600 million yuan to eliminate production bottlenecks and ensure the upgrading of Jingliu oil products.
At present, Yanshan Petrochemical's Jingliu gasoline has a monthly production capacity of 250,000 tons and an annual supply of 3 million tons, accounting for about 75% of Beijing's gasoline use. The other 25% is supplemented by Sinopec Qilu Petrochemical, Yanzhou Refinery and PetroChina Jinzhou Petrochemical, Jinxi Petrochemical, Huabei Petrochemical, and Dagang Petrochemical.
Jaw Crushers are used to reduce the size of many different types of materials in many applications. as a double-toggle Jaw Crusher. ... These combined motions compress and push the material through the crushing chamber at a predetermined size.
Crushing raw material takes its toll on your equipment. For every ounce of product that passes through your machinery, the lifespan of your equipment steadily decreases. This leads to decreased output and mounting maintenance and repair costs. We have created a solution, built on more than a hundred year`s worth of jaw-crusher experience.
