On September 1, 2013, Shanghai began to work on the replacement of Shanghai V standard gasoline and national V standard diesel. At that time, because diesel had a national standard equivalent to the European V standard, and there was no gasoline, Shanghai adopted the local standard for gasoline, namely the Shanghai V standard. Since November last year, Shanghai major gas stations have been supplying Shanghai V standard gasoline and national V standard diesel. According to the regulations of the Shanghai Municipal Government, from May 1st, the quality standards for motor gasoline sold in Shanghai must meet the requirements of the National V, and the current implementation of the Shanghai V gasoline standard. In the "Sinopec Shanghai Petroleum Public Open Day" event, the relevant person in charge of Sinopec Shanghai Petroleum Branch said that the quality indicators of the Shanghai V gasoline standard and the national V gasoline standard are basically the same, which are equivalent to the European V standard. Compared with the original Shanghai IV standard gasoline, the main environmental indicators have changed greatly. For example, the limit value of sulfur content is reduced from 50 mg per kilogram to 10 mg per kilogram, which is reduced by 80%; nitrogen oxides, monooxides, carbon Hydrogen compounds are reduced by 15%-20%. The reporter saw at Sinopec Shanghai Petroleum Quality Inspection Station yesterday that the inspectors used a special needle to pump 10 microliters of Shanghai V standard gasoline, slowly inject it into the nitrogen sulfur analyzer, and then use the high temperature heating of the instrument to volatilize the oil; On the computer monitor, it is gradually shown that the fluctuation curve of the sulfur content during the evaporation of the needle tube oil can be accurate to every second. Finally, this syringe oil shows a sulfur content of 8.45 mg per kilogram, which meets the national V standard. At present, there are more than 800 gas stations in Shanghai, of which Sinopec has 582 gas stations in the camp. It is understood that Sinopec supplied 3.5 million tons of gasoline and diesel to Shanghai last year, accounting for about 70% of the total market in Shanghai. Sinopec stipulates that if a gas station receives two complaints about the quality of the oil continuously, the gas station will stop operating for inspection to ensure the quality of the oil sold.
