China's petrochemical industry has reached the mid-to-high level in terms of product varieties and technological levels. However, there are still gaps compared with the international advanced level, which is mainly reflected in the intrinsic quality level of the industry. The petrochemical industry represented by oil refining, ethylene, aromatics, organic materials, and synthetic materials is the upstream of oil and natural gas resources. The downstream of the petrochemical industry can be extended to fine chemicals, special materials, etc. in the oil and chemical industry. The key link in the chain is the link. Combining with the current situation, the petrochemical industry must take the road of ascending development in order to truly support the development of China's petroleum and chemical industries.
Refining industry From the perspective of the future situation and tasks of China's oil refining industry, the refining capacity will continue to grow steadily, which is in line with the growth of refined oil demand. The reconstruction of refineries is mainly concentrated on secondary processing capacity devices. The purpose of the transformation is to adapt to the trend of crude oil inferiority, improve the processing level and meet the general trend of China's oil quality upgrade.
During the “12th Five-Year Plan†period, the refining industry will continue to eliminate backward production capacity. According to the principle of "total control, internal optimization, elimination of backwardness," the principle of simultaneous advancement, China will eliminate some small-scale atmospheric and vacuum units that do not have competitiveness; for small-scale oil refineries that are not within the scope of elimination, they should make full use of market resources. Strict environmental protection supervision and product quality inspection will guide the development of differentiated specialty products.
The task of energy-saving and emission reduction for refinery companies is arduous. The refining industry is facing crude oil inferior quality pressure and oil quality upgrading. Some refineries need to build or renovate hydrogenation equipment for residue hydrogenation, wax oil hydrocracking, wax oil hydrogenation, and hydrogenation of gasoline and diesel, and they also need to improve supporting facilities. The hydrogen production, sulfur recovery, storage and transportation systems and other supporting projects.
Therefore, the focus of the structural adjustment of the oil refining industry will be on the following aspects: further increase the degree of intensive petroleum refining industry; improve the environmental protection level of oil products; consider oil production ratio as a whole; increase processing levels and achieve connotative development; optimize industrial layout and improve logistics System; technical structure adjustment.
Ethylene Industry With the development of the refining industry, China's ethylene industry has also entered a period of steady growth. During the "12th Five-Year Plan" period, with the deceleration of the domestic economic growth, the equivalent consumption of ethylene will show a slow growth.
It is worth noting that quality raw material resources are still one of the factors that restrict the development of the ethylene industry. China's dependence on crude oil has exceeded 55%, and the supply and demand of raw materials facing the development of the ethylene industry will further intensify. At the same time, the high crude oil price will increase the cost of raw materials for the ethylene industry.
Energy-saving and emission-reduction pressures also test the ethylene industry. The target of ethylene flaring energy consumption in the "Twelve Five-year Development Plan for Olefins Industry" released by the Ministry of Industry and Information Technology is less than 857 kg standard coal/ton ethylene. In recent years, new large-scale ethylene plants can achieve this goal, but old devices still have Big stress.
In the face of these problems, we must actively advance the restructuring of the ethylene industry. First, we must give full play to the advantages of refining and chemical integration, increase the degree of matching of refinery equipment and ethylene plants, strengthen the recycling of dry gas and light hydrocarbons in refineries, and maximize the optimization of resources. The second is to extensively purchase resources such as naphtha, condensate oil, and light hydrocarbons, and moderately advance the development of methanol to olefins to increase the diversification of raw materials. The third is to improve the utilization of raw materials by processing the by-products or combining them with the enterprises in the park. The fourth is to improve the technology of heavy oil processing and olefin production. Fifth, speed up the adjustment of ethylene downstream product structure and increase the proportion of high-end products.
In the aromatics industry, the market demand for benzene, toluene and paraxylene is relatively large, and the demand in the domestic market will slow down during the “12th Five-Year Plan†period. There are regional differences in the production capacity of aromatic hydrocarbons in China, which has affected the development of petrochemical downstream industries to a certain extent, and has reduced the opportunities for the development of extended products. During the “Twelfth Five-Year Plan†period, the refinery industry will be adjusted in a timely manner in conjunction with the opportunity for refining companies to import or distill oil.
During the “12th Five-Year Plan†period of organic raw materials industry, along with the construction and renovation of a number of petrochemical projects in China, the supply of organic chemical raw materials such as ethylene oxide, ethylene glycol, propylene oxide, acetic acid, styrene, and phenolacetone is taking place. Changes, the shortage of some products will slow down, but at the same time some traditional products such as acrylic acid and esters, acetic acid, butyl octanol and other future market capacity growth is limited, is forming a comprehensive market competition.
Generally speaking, at present, China's organic raw material industry still has the problems of small scale, low technology, high cost, high consumption, etc. It is also necessary to further upgrade the level of process technology and equipment, and appropriately increase the scale of the varieties.
By the end of 2012, the total output of the five general-purpose synthetic resins in the composite materials industry is expected to reach 61.69 million tons, which is only 6.3 million tons from the target set forth in the “Twelfth Five-Year Development Plan for Petrochemical and Chemical Industryâ€. Under such circumstances, it is particularly important to upgrade product quality, increase the development and productivity of specialty materials, and enhance the level of differentiation.
In the field of synthetic rubber, special rubber has attracted more and more attention in recent years. In the future, the outlook for the specialty rubber market is generally better and has potential for development. Nitrile rubber, halogenated butyl rubber, ethylene propylene rubber, isoprene rubber, and chloroprene rubber of the butadiene route are key products for the synthetic rubber industry in the next few years.
