Sample quality inspection of gasoline and diesel

“We found in this random inspection that some of the social gas stations actually used low-standard oils to sell high-standard oil and poor quality oils were doped into qualified oil.” On November 26, the Hunan Provincial Bureau of Quality Supervision announced the use of vehicle oil. The results of quality inspection showed that the overall average rate of car oil in the province was 84.1%. Among them, Sinopec and PetroChina all qualified for oil sampling, and all 8 social gas stations sampled by the provincial capital in Changsha were qualified, but there are four other social gas stations in other cities and counties. Become unqualified.

At present, 95 unqualified petrol stations in the province have received notices of corrections. There are 32 oil stations that have passed the rectification review, 35 oil stations have been investigated, and 28 petrol stations are being processed. The Provincial Bureau of Quality Supervision reminds owners that because some social service stations are only profitable, they must be alert to the use of low standard oils to sell high standard oil, poor quality oils to be sold in qualified oil, and other “hidden rules”.

The quality of sampled Changsha all gas stations are qualified

“At present, there are 3785 gas stations in the province, including 1,535 Sinopec, 537 PetroChina, and 5 CNOOC, accounting for more than half of the number of gas stations. Sales account for 90% of vehicle oil in the province; there are 1708 social gas stations in the province. According to Xu Xinchu, deputy director of the Provincial Bureau of Quality Supervision, the sampled 510 gas stations, refined oil reserves, and Sinopec Baling Branch and Changling Branch of the 14 cities and counties were qualified for 767 batches and 145 batches that were unqualified. The average spot check pass rate is 84.1%. Among them, the refinery and refined oil reserves, Sinopec gas stations, PetroChina gas stations, and CNOOC gas stations are 100% qualified for random inspection batches, and the sampling pass rate for social gas stations is 61.3%, and nearly 40% are unqualified. .

Xu Xinchu said that the size of the spot inspection is unprecedented and it has a wide coverage. “The eight social gas stations sampled by the provincial capital Changsha have all qualified oil. Overall, the qualified rate of gas stations in the Chang-Zhu-Tan area is higher than that of other city and state gas stations, and the qualified rate of spot-testing at the gas stations in each city is higher than that of the county. Township gas station."

"Social gas station batch pass rate is lower, but the proportion of total sales of oil products is also very small." Xu Xinchu introduced that in 2012 the province's total consumption of gasoline and diesel was about 8.21 million tons (3,020,000 tons of gasoline, diesel 519 10,000 tons), including Sinopec's 6.08 million tons (oil 2.29 million tons, diesel 3.79 million tons), PetroChina 1.84 million tons (petrol 590,000 tons, diesel 1.25 million tons), and 290,000 tons of other social oil stations (14 million tons of gasoline, 150,000 tons of diesel fuel only accounted for 4% of sales. "The conversion rate for gasoline and diesel in the province was 96.2%."

The 97th Gasoline Passing Rate is higher than 93

Provincial Quality Supervision Bureau compared unqualified vehicles with gasoline and diesel and found that the qualified rate of No. 97 gasoline was higher than that of No. 93 gasoline, and the pass rates were 94.2% and 80.2% respectively; the pass rate of regular diesel was higher than that of vehicle diesel The pass rates were 90% and 72.1%, respectively.

In this sampling inspection, unqualified 145 batches of vehicle oil were mainly unqualified by two indicators, one was octane number and one was sulfur. According to the relevant person in charge of the Provincial Bureau of Quality Supervision, these two indicators are the key indicators affecting the engine of an automobile. An octane number that is too low means that the oil cannot be fully burned and the discharge is unstable; if the sulfur content is too high, the car can easily corrode. Trachea and other components, and sulfur is one of the important causes of atmospheric pollution and ash.

Xu Xinchu said that since the No. 97 gasoline process requires more than No. 93 gasoline, small refineries simply cannot do so. In addition, for the sake of reducing costs, many social gas stations are working on gasoline No. 93, and the issue of adulterated sales is relatively prominent. According to regulations, the octane number of No. 93 gasoline is not less than 93, but the No. 93 gasoline of Shuangsheng Gas Station of Xinhua County Huashan Gas Station and Longtang Town of Wuyuan City has an octane number of only 81.5, which is lower than the standard value of 11.5%. Compared with the standard value of No. 90 gasoline, it is 8.5 percentage points lower. According to regulations, the sulfur content is not more than 0.015%, while the sulfur content of No. 93 gasoline in Xintang Gas Station in Miluo City reaches 0.27%, which is 18 times the standard value.

Authoritative analysis of some social gas stations "hidden rules" prevail

“The most exposed social oil stations this time are not organized by industry associations and the quality of oil products is difficult to manage.” According to the relevant person in charge of the Provincial Bureau of Quality Supervision, only the social gas stations in Changsha have established industry associations. A Changsha social gas station oil was qualified. In addition, the sources of oil products from the gas stations in the society are unstable, lack of inspection and inspection capabilities, and the difficulty in checking the quality of oil products is also the main reason. The most hateful thing is that some social service stations are mercenary and "hidden rules" are prevalent.

Xu Xinchu said that the "hidden rules" worthy of the owner's vigilance include: using high-standard oil to sell high-standard oil, and using inferior oil to be sold in qualified oil. "In the sampling inspection, we collected several marking oils in the same oil tank."

According to reports, in addition to oil refinery factors, those gasolines with high sulfur content may be sold by some unscrupulous traders with high-sulphur, unqualified oil products in qualified oil products; the oxygen content or methanol content is too high. Gasoline, may be the operator or supplier intentionally incorporation of low-priced industrial methanol in qualified oil products, causing an illusion of high octane value. "These actions are involved in the production and sale of fake and shoddy products and are illegally gaining improper and legitimate profits!" said Xu Xinchu.

Oil upgrades will be implemented from New Year's Day next year

At present, exhaust emissions have been linked to industrial dust, construction dust, and plant protection damage to become the four major causes of air pollution, and oil upgrading is imminent.

On the 26th, Pan Guimei, General Manager of Hunan Branch of Sinopec, and Xu Yi, General Manager of PetroChina Hunan Branch, said that at present, the two major oil plants of Sinopec, PetroChina, Baling Petrochemical and Changling have completed the connection of production and sales, storage equipment and technological transformation. It has the ability to fully put into the market four national standard gasoline and three national standard diesel fuels. It is expected that the replacement will be completed by the end of November and the beginning of December, and the premium price will be implemented from January 1 next year.
