At present, the oil price is falling, which makes people feel refreshed! Don't say that the price of oil has fallen, as long as it doesn't increase, thank God! So I can only continue to hope that the oil price will go lower and lower! As a result, those who originally added 92 began to try to add 95, which they could not bear. But wait! The old topic is coming again: PetroChina, Sinopec, whose family to add?
There is a very popular saying on the Internet that South Petrochemical Company and North Petroleum Company. It generally means that Sinopec monopolizes the south, and Sinopec is the better oil product in the south; And the north is the opposite. So is this statement right or wrong? Why is there such a statement? This seems to remind people? South Telecom and North Unicom? Come on.
The origin and background of PetroChina:
Roots are red and seedlings are positive! Oil boss!
please come out first? Big brother? PetroChina! Why is it called big brother? This also makes sense. Because it is the largest oil company in China, there is no one! Its predecessor was the Ministry of Petroleum Industry of the People's Republic of China. Most of the members are from the first batch of veterans and officers after liberation. Is PetroChina real? Root red seedling is? .
The Ministry of Petroleum of China, which has a strong military color, has been written into primary school textbooks for countless times, such as Daqing Oilfield and Shengli Oilfield, which we are familiar with. Iron man? Wang Jinxi, etc., so after the restructuring into an enterprise, PetroChina is still the largest oil enterprise in China, and there is no one! At present, the total amount of fuel refining in the whole year is less than twice that of PetroChina.
The origin and background of Sinopec:
Balancing the oil supply between the north and the south
On the other hand, what kind of existence does Sinopec have? At that time in 1983, before the Ministry of Petroleum became PetroChina, some departments and teams in the department were pulled out, and then some leading bodies and key personnel were transferred from the Ministry of Chemical Industry and the Ministry of Textile respectively to form another oil enterprise in China.
the purpose is simple: to adapt to the great development of transportation after China's reform and opening up at that time. Because of historical reasons, PetroChina has undertaken almost all the domestic onshore oil field operations and exploitation business, and less involved in the import of crude oil business. Similar problems are also reflected in CNOOC (CNOOC was established in 1982 to develop China's offshore oil resources and was directly under the jurisdiction of the State Council)
Therefore, at that time, China urgently needed to import a large number of foreign crude oil to plug the loopholes in gasoline and diesel consumption. On the other hand, most of China's land oilfields are located in the north of China, while there are few oilfield resources in the south. In order to balance the supply network of gasoline and diesel in the north and south of China at the same time, Sinopec came into being under this background.
The domestic oil fields are attributed to PetroChina
The crude oil is inferior, but the gasoline is poor
Because of this layout in that year, PetroChina gas stations were everywhere in the northern part of China, while in the southern part, on the contrary, Sinopec was everywhere. So some netizens said that most of the crude oil used by PetroChina is directly refined from domestic oil fields; Sinopec, on the other hand, imports more crude oil, and the quality of oil in the Middle East is too good, so the raw materials are good and the gasoline comes out naturally.
so is this statement right? Because Dahuyou saw that this statement is relatively mainstream on the Internet. But Dahuyou thinks maybe this opinion is? Pass it on? . In fact, there are two doubts here: first, in order to avoid monopoly, the state gave it back around 199. Two barrels of oil? Assigned it? Resources? .
in those days, the oilfields were basically redistributed to PetroChina in the north of the Great Wall and Sinopec in the south of the Great Wall, so as to avoid monopolization by one company. Therefore, Shengli Oilfield, Zhongyuan Oilfield, Huabei Oilfield and Henan Oilfield were all allocated to Sinopec. That is to say? PetroChina only refines domestic oil fields, while Sinopec only plays with imported crude oil? The era, as early as the past decades! I really don't want to talk about this old rotten valley!
Sinopec smelts imported crude oil with high-grade raw materials and good gasoline
The second doubtful point is that the quality of crude oil imported by Sinopec is higher than that in China. In fact, Da Huyou talked about it last year. Did foreigners treat us in China? Control? But really not fooling around. Good things for China? I'm afraid you haven't woken up yet! The real high-purity light crude oil has long gone to the United States. Where can we get China?
In fact, most of the crude oil that China gets from the Middle East Gulf is medium or even low-quality crude oil with high sulfur content. The price is indeed cheaper than the high quality, but it needs a more stringent smelting process? Serve? . Most of the oil and gas resources from Russia are natural gas, and there are few oil resources.
everyone? Central enterprises? Is the gap really that big?
therefore, from this point of view, the difference between the crude oil sources of PetroChina and Sinopec is not too big. Moreover, as a super central enterprise, one is the former Ministry of Petroleum, and the other is the joint establishment of some departments from the former Ministry of Petroleum, the Ministry of Chemical Industry and the Ministry of Textile. Are they all in the domestic oil industry? Taishan Beidou? There won't be much difference between scientific research strength and smelting process.
Sinopec began to introduce from Britain in 28 because of its deepening cooperation and joint venture with BP Group (British Imperial Oil Company)? Patented multiple cracking technology? The quality of gasoline and diesel oil produced is obviously improved (ideally, 97/95 label can be directly extracted without any additives).
PetroChina also cooperates with BP Group, and its Lanzhou Petrochemical Company is not a vegetarian. Recently, their self-developed LZR-3R catalytic cracking catalyst successfully won the bid for Chevron California Refinery in the United States, marking its recognition in the international high-end market. To say the least, no matter Sinopec or PetroChina, there will be no shortage of national treasure professors at the level of academicians of the Chinese Academy of Sciences.
whether gasoline can burn or not depends on its density!
then there is only one reason that ultimately leads to whether gasoline can burn or not: gasoline density. Because the computer of the car controls the air-fuel ratio, according to? Weight? For the unit. Usually, for every 15 grams of air inhaled by the engine, the fuel nozzle needs to spray 1 gram of gasoline. Then mix and ignite, and then the engine runs.
but what is the unit of measurement when we refuel? Litres? . Therefore, we come to a conclusion that the higher the density of gasoline, the more resistant it will be to burning. Because the same box of gasoline is heavier! There is an article on the internet saying? Do Sinopec and PetroChina have different gasoline densities? And I looked up the national standard of gasoline physical indicators: GB-1793-216 National Standard for Automobile Gasoline.
According to the national standard, the density of current national 6A gasoline must meet the standard of 72g ~ 775g per liter (temperature 2 degrees) to be qualified. According to this standard, the weight of 1 liter of gasoline may be 5 grams (one or two) because of different refiners! According to the average fuel tank of an ordinary family car of 5L, the biggest gap will reach 2,5g (2.5kg) < P > 2.5kg of gasoline will probably be over 3.5L, which will probably make the car run about 5km more (or less) (most cars). So from this perspective, the oil products of different brands of gas stations may really lead to this? Burning resistance? The difference.
after that, according to the gasoline density of different local gas stations in Shanghai, if conditions permit, we may actually do the first phase of gasoline density measurement, but the conditions are not ripe at present.
