The capacity growth of the hottest domestic ethyle

  • Detail

The capacity growth of domestic ethylene and oil refining projects lags behind.

although the current international crude oil price has rebounded significantly, the bearish atmosphere in the domestic propylene market has not been reduced. It seems that the market is still difficult to make a big improvement in the near future. However, the capacity growth of China's propylene market lags behind, and the market gap will still exist for a considerable period of time

rapid growth of downstream demand

zhouchunyan, Research Institute of PetroChina Jilin Petrochemical Company, introduced that propylene is mainly used to produce polypropylene, accounting for about 58% of the global propylene demand, and up to about 75% in China; Another major use is to produce acrylonitrile, propylene oxide and other chemical products, accounting for about 25% of the total propylene consumption. In the future, polypropylene will still be the largest derivative of propylene, and its proportion in the total demand for propylene will be further increased; In order to meet the needs of acrylic fiber and ABS resin production, China will continue to expand the production capacity of acrylonitrile, and its consumption of propylene will also maintain a high proportion in the propylene consumption structure

it is learned that in recent years, driven by the rapid growth of the demand for downstream derivatives, it was found that this kind of mixture adhered to the combustibles for a longer time than ordinary flame retardants, and the consumption of spherical propylene increased significantly. At the same time, the production of propylene in the world is also developing rapidly. Asia, North America and Western Europe have always been the most concentrated propylene production and consumption regions in the world. However, from the development trend in recent years, the growth rate of production and demand in North America and Western Europe is significantly lower than the world average level, and their proportion in the world propylene market is gradually declining. At the same time, Asia, especially the Middle East, plays an increasingly important role in the world propylene market. Before 2012, the world's new propylene production capacity was mainly concentrated in this region, accounting for about 76% of the world's total new capacity

capacity growth is relatively lagging

as domestic ethylene and large-scale oil refining projects are controlled by national macro policies, it is difficult to implement the crude oil source of small oil refining enterprises, resulting in a high monopoly of domestic propylene production. In 2008, China's total propylene capacity was about 10.5 million tons, and its units were mainly concentrated in Sinopec and PetroChina, accounting for about 90% of China's total propylene capacity. In addition, CNOOC has a set of 400000 T/a propylene plant, and other companies such as China National Chemical Corporation and Sinochem International also have some small-scale oil refining enterprises to produce propylene. In addition, some small oil refining enterprises have an annual propylene production capacity of about one million tons. Due to the restriction of national oil refining policies and the impact of international oil prices, the output and operating rate of small and medium-sized oil refining enterprises are low. Although there is not a large amount of propylene output in China, propylene production enterprises basically have downstream supporting production units, but the amount of commodities provided to the market is not large

guanjunchao, an organic synthesis plant of PetroChina Jilin Petrochemical Company, said that China's propylene production can be divided into two categories according to the source: first, cracking propylene, which comes from ethylene cracking unit, is a co product of ethylene; Second, refinery propylene is separated from FCC refinery gas. Propylene from both sources occupies a very important position. The production capacity of CO production of propylene by steam cracking accounts for about 47% of the total production capacity in China; The production capacity of propylene produced by FCC unit in refinery accounts for about 53%

in the 1990s, with the rapid development of petrochemical industry, China's propylene production capacity increased significantly. With the completion of large-scale ethylene production units and the completion of potential tapping and transformation of existing ethylene production units, the production capacity of ethylene units to co produce propylene in China has increased, and the propylene output of refineries has also gradually increased in the same period. The total output in 2008 exceeded 10million tons. However, due to the relative monopoly of propylene market and lack of competitive vitality, the growth of propylene production in China has been lagging behind the growth of demand

the supply shortage market is improving

zhouchunyan said that, on the one hand, China's propylene market capacity growth lags behind, on the other hand, the two major groups have a rich variety of propylene downstream products, and the capacity of supporting products is equivalent to that of propylene. Very few propylene can be supplied externally, resulting in the need for many downstream enterprises to import propylene from abroad. On the surface, in recent years, China only needs to import hundreds of thousands of tons of propylene each year to meet the demand, accounting for only about 3% of the domestic apparent consumption, which is basically in the balance between supply and demand

however, there is a huge gap between domestic supply and demand. In addition to importing a small amount of propylene monomers, a large number of downstream derivatives such as polypropylene, acrylonitrile and propylene oxide are also imported every year. If the import volume of these downstream products is converted into propylene demand, the domestic equivalent market gap will be more than 4million tons

it is learned that in the next few years, China will add several large ethylene production units, and the production capacity of refineries will continue to expand; The large-scale coal to olefin projects being built by some enterprises such as China Datang and China Shenhua are also in full swing. At present, no specific customers have been revealed. It is expected that China Datang's 460000 ton coal to olefin project and China Shenhua's 600000 ton and 520000 ton coal to olefin projects will be completed and put into operation next year, which will significantly increase the domestic propylene output. By 2010, China's propylene production capacity is expected to reach 12.65 million tons. However, it is predicted that the market demand will reach 15million ~ 16million tons in 2010. There is still a gap that a hydrophobic film is coated on the glass surface
