After years of rapid development, petroleum and chemical industry in China's economy has been ranked among the top of the world, starting in 2010, our country has become the world's largest producer of chemicals and the second largest producer of petrochemical products. In 2016 China's refining capacity is about 7.94 x 108 t/a, crude runs throughout the year of 5.41 x 108 t, refining capacity utilization rate of less than 70%, the refined oil yield of 3.48 x 108 t, product oil consumption is 3.15 x 108 t, net exports increased to 3355 x 104 t, further consumption Chai Qibi further down to 1.37, diesel surplus seriously, refined oil exports (especially diesel exports) will present the norm and the characteristics of the scale. Benefit from a large number of coal to olefin (CTO), methanol to olefins (MTO), propane dehydrogenation (PDH) device is completed and put into operation, rapid growth of olefins, especially propylene ability, ethylene and propylene production capacity of 2313 respectively 2016 x 104 x 3396 t / 104 t/a and a, diversified raw material rate were 21.7% and 38.4% respectively, production is respectively 2126 x 104 x 2500 t, 104 t and equivalent rate increased to 53% and 53% respectively. At present, most domestic petrochemical products overcapacity, but for some organic materials such as dimethyl benzene, ethylene glycol and styrene is still a large number of imports, at the high end and need to be close to the diversification of the market to provide technical services, custom fields, a serious shortage of domestic supply. In recent years, the Middle East petrochemical products have started to flood the Chinese market with their price advantage, making the domestic market more competitive.
The refining industry in China has developed rapidly in recent years. In 2010, China's crude oil processing capacity was 5.48 x 108t/a, and the processing volume was 4.23 x 108t, and the three types of oil products were 2.5108t, and the consumption of the surface consumption was 2.45x 108t. In 2016, China's crude oil processing capacity is 7.94 x 104 t/a, independent refiners for applying for import of crude oil using qualification of backward production capacity of 2933 x 104 t/a, capacity structure is optimized. Crude oil processing capacity of 5.41 2016 x 108 t, fuel type enterprise and fuel - chemical type (refinery) enterprise average utilization was 71.3%, significantly lower than the world average oil refining. In 2016, net exports of refined oil products reached 3356 x 104t, and the export of refined products (especially diesel exports) will be characterized by normalization and scale.
First, there is still a shortage of advanced capacity. Refining capacity nationwide census, in 2012, according to the results of energy consumption per unit energy factor in 8.5 kg of standard oil/t. factor and oil refining enterprises only under sinopec guangzhou branch, sinopec zhenhai refining branch 13 companies, such as a total crude oil processing capacity is 14950 x 104 t/a, only 18.8% of the total capacity.
Second, there is a large number of backward production capacity with small scale and low technical level, which is difficult to adapt to the development requirement of intensive and large-scale refining industry. According to the China petroleum and chemical industry federation (CPCIA) statistics, by the end of 2016, 200 x 104 t/a refinery under a total of 68 seats, total capacity is 4781 x 104 t/a, only the average capacity is 70 x 104 t/a, only the large refinery has a batch of backward small device.
Third, the level of integration needs to be further improved. At present our country only 17 of 24 m each refinery has realized the integration of refining, crude oil refinery enterprises a processing capacity of 23960 x 104 t/a, accounted for 30.2% of the national total capacity.
In recent years, the adjustment of industrial structure makes the product oil major changes have taken place in the consumption structure and outstanding performance in consumer Chai Qibi reductions and has decreased from 2.18 in 2010 to 1.50 in 2015, Chai Qibi further fell to 1.37 in 2016. Future fuel consumption growth will be much slower than gasoline, oil demand differentiation trend more obvious, predicts 2020 consumption Chai Qibi dropped sharply to 1.1 below, while production Chai Qibi fell to 1.18 or so, the future diesel resources excess fuel, gasoline into balance. This paper puts forward the new requirements for the structure of the refining products and the adjustment of the device structure, and the reduction of the production of firewood is more difficult than the task. 2016 domestic fuel demand is 3.15 x 108 t, according to the refined oil products in China's oil refining industry in recent years the average yield of 62% 62% and the reasonable utilization, rational allocation of refining capacity of 6.35 x 108 t/a, the existing fuel type and fuel - chemical enterprises of crude oil processing capacity is 7.59 x 108 t/a, the excess of 1.24 x 108 t/a.
By China's economic growth is slowing, steady progress of structural adjustment and the traditional industry depth adjustment factors, such as "much starker choices-and graver consequences-in" during China's oil demand growth will slow to below 3%, oil demand in 2020 is expected to reach 3.65 x 108 t. According to the current various refining enterprise, planned and planning project under construction is calculated, taking into account the backward, a domestic crude oil processing capacity of 2020 is expected to reach about 8.8 x 108 t/a. Calculated according to 62% of the refined oil yield and 62% utilization, rational allocation of oil refining capacity of 7.36 2020 x 108 t/a, the excess capacity still at about 1.4 x 108 t/a, overcapacity situation is still grim.
To reduce vehicle exhaust pollution, improve the national ambient air quality, effective governance fog haze, promote green development and sustainable development, product quality upgrading in China continue to accelerate, during the period of "much starker choices-and graver consequences-in", 2017 car petrol and diesel are upgraded to national Ⅴ standards, 2019 up to national standard Ⅵ A stage. By the end of 2016, our country Ⅴ gasoline and diesel fuel production capacity increase to 11477 by 104 x 15303 t / 104 t/a and a; There are only A few companies such as sinopec yanshan petrochemical company can producer Ⅵ standard of gasoline and diesel, the Ⅵ A petrol and diesel capacity respectively 355 x 104 x 280 t / 104 t/A and A. Therefore, in order to meet the requirement of upgrading the quality of oil products, the refining industry in China needs to improve the equipment and improve the processing level.
The overall surplus of oil refining capacity in China and the fierce competition in the industry have shown a marked decline in refining capacity in recent years. 2010-2016, crude runs an annual increase of only 4.2%, the national refinery capacity utilization has decreased from 77.2% in 2010 to 71.3% in 2016, local refinery capacity is less than 40% on average.
Alternative fuels are growing rapidly, squeezing the market for products. China's alternative fuel present diversification trend, gradually formed a is given priority to with natural gas, electric, methanol, biofuels and coal, and other forms of common development pattern. During the 13th five-year plan period, electric vehicles will develop rapidly, and the proportion of alternative fuel consumption will rise from nearly 6.5 per cent to about 10.5 per cent.
Competition for refined oil products in China is intensifying. In recent years, the international oil companies to speed up the oil and gas resources countries and emerging markets large oil refining project layout, the Middle East part of developing export-oriented oil refining industry, resource countries and India around some traditional Chinese refined oil importing countries are developing their own petroleum refining industry. China's exports of refined oil products have risen sharply, which will squeeze the market share of traditional oil exporters, and competition in the oil market in northeast Asia will intensify in the future. At the same time, domestic companies will be under more pressure to price.
