China's oil refining industry has made great efforts to meet the requirements of national standards, and ordinary people do not understand. Each upgrade means a huge investment, including investment in scientific research and development, how to realize this technology, if it is not possible to buy foreign, tens of millions of dollars in patent fees, technology packages.
You also need to invest in your own research and development, and invest a lot in the laboratory, pilot test, industrial experiment, and increase of operating costs. Each additional process increases costs. In order to adapt to the ever-increasing hydrodesulfurization, which has undergone continuous improvement, it is now necessary to meet the national VI, and the price paid by the oil refinery is too great.
From the perspective of capital investment, PetroChina's refining and chemical sector has invested a lot of money, and it is also constructing these two aspects of equipment to improve oil quality.
In terms of oil product upgrades, Sinopec acquired the patented Phillips catalytic gasoline desulfurization patented technology in 2010, and innovated the device based on this technology, forming a new generation of S_Zorb patented technology with its own characteristics. The problem of long cycle operation. The original device operated for about 4 months, but now it can be up to 3 years. Sinopec has about 25 sets of S_Zorb technology, with a total processing capacity of more than 31 million tons per year.
In terms of cost, if the national Ⅴ and national Ⅵ standards are added with alkylated oil, the cost of one ton will increase by about 200 yuan, and the lost octane number will be supplemented by the high octane number component. To restore the octane number, Pay the economic price.
The harsh scale of the existing device is improved and can also meet the requirements for oil upgrades. However, the life of the device will be reduced, the life cycle of the catalyst will be shortened, and a lot of costs will eventually be invested. These costs can be tolerated by oil refiners at low oil prices, and there are problems at high oil prices. It is recommended that the state reduce fuel taxes and other measures to reduce corporate costs.
