The world exclusive production of propylene is more than the rapid growth of propylene
According to the report, with the production of new production of propylene, the supply of propylene will significantly exceed the expected increase in the next five years. However, if the propylene ethylene prices relative to larger gap appeared similar to the 1990 s, is likely to accelerate the propylene demand growth, because of the polypropylene (PP) may once again become a more competitive low cost plastic resin, senior director of IHS chemical world olefins business chuck Carl (ChuckCarr) in Houston 2014 world petrochemical said in a speech in the conference.
In 2000, according to IHS chemical data world specially producing propylene production accounts for only 3% of the total supply of propylene, but in 2013, designed to produce propylene production has accounted for 14% of the total supply of propylene, is expected to increase by 2018 to 29% of the total supply. Most of the new production capacity comes from China, Mr Carr said. In the United States, over the past six years due to ethylene cracking use more lightweight materials propylene supply falling nearly 40%, however, a large supply of propane, together with the price of crude oil is relatively high gas prices, has made the propane dehydrogenation unit will become the main future propylene supply growth engine. It is predicted that global propylene capacity will increase by 30m tonnes over the next five years, while demand growth is expected to be only 22m tonnes, a gap between supply and demand that could lead to lower propylene prices. In addition, the production of new propylene will also lead to a large number of new capacity-building for non-polypropylene derivatives. Earlier, the latter's margins were strong due to overinvestment in polypropylene and inadequate investment in non-polypropylene derivatives. A new round of non-polypropylene derivatives investment is on the upsurge, and much of it is built with the Asian production facility of propylene production, he added.
In North America, because of the harmonic of octane value added demand of gas, and shale development isobutane significant increase in the supply, and makes many refineries level consider refinery propylene by alkylation process to produce high octane number components to return to the gasoline pool, this will be for the past few decades exit refinery propylene alkylation into complete reversal of chemicals market.
