The hottest propylene gap expands, propane dehydro

Propylene gap expands propane dehydrogenation has become a new hot spot for investment

at the end of April, Qixiang Tengda announced that it would raise funds to build a 100000 t/a propane dehydrogenation project; Fujian Meide petrochemical company also announced not long ago that it will build a propane dehydrogenation project with an annual output of 660000 tons of propylene, which is expected to be put into operation in 2015. According to statistics, the total capacity of propane dehydrogenation projects planned to be built in China at present reaches 9.2 million tons, while the capacity planned to be put into operation in 2013 is 1.05 million tons. In recent years, domestic propane dehydrogenation projects have developed in full swing. Even the United States has announced that it will build seven propane dehydrogenation units with a total annual capacity of 2.7 million tons. Propane dehydrogenation project has quickly become a new hot spot for investment

propylene gap continues to expand

propylene is an important basic petrochemical raw material next to ethylene, and naphtha steam cracking is the main way to obtain propylene. However, in recent years, with the large-scale application of shale gas, the cracking plant raw material for ethylene production has shifted from high priced naphtha to cheap ethane to reduce production costs, resulting in a significant reduction in the production of propylene, a by-product. At present, the cost of ethylene per ton of ethane method is only 38% of that of naphtha method, and the gross profit per ton is three times that of naphtha method, while the production of propylene by-product is only 1/6 of that of naphtha method. According to the analysis of experts from the U.S. investment bank, as of the beginning of 2013, the propylene output of the United States naphtha steam cracking unit has decreased by 2.3 million ~ 2.7 million tons/year, and it is expected to reduce by at least 1.4 million tons/year by 2015

refinery propylene is the second largest source of propylene, but catalytic cracking unit mainly produces gasoline, and propylene accounts for only 3% - 6% of its output. Although the propylene yield can be further improved by optimizing the operation to improve the success rate of the experiment, the growth rate of propylene production is limited. From 2004 to 2010, the global ethylene production capacity increased by 34%, while the propylene production capacity increased by only 25%

while the global propylene production capacity is growing slowly, the propylene demand is growing rapidly, and the gap is widening. The data shows that the annual demand for propylene in China in the past two years is close to 20million tons, and the balance between supply and demand is about 5million tons. China accounts for more than 15% of the global propylene demand, and its consumption is still growing at a rate of 5% - 6% per year. According to customs data, China's total propylene import in 2012 was 2.1474 million tons, a record high, an increase of 22.3% compared with the import scale of 1.7552 million tons in 2011

significant benefits and accelerated investment

due to the huge gap in propylene, people began to look for new ways to produce propylene. Among them, propane dehydrogenation has become a hot topic for enterprises because of its relatively small scale, low investment, high efficiency and high return on investment. "Propane dehydrogenation, time is money, advance is advantage", a well-known securities company's 2013 annual report on the petrochemical industry is even more so. Industry insiders predict that the pre tax profit of domestic propane dehydrogenation projects in 2014 can reach 1000 yuan/ton, and most believe that the profit of the propane dehydrogenation unit first put into operation by our Jinan experimental machine factory Jinan new period gold testing instrument Co., Ltd. will also be higher

in recent years, the price of raw propane has shown a downward trend, which is also conducive to improving the profitability of propane dehydrogenation projects. At present, the import tariff of propylene is only 1%, and the expected profit and low tariff make many enterprises chase after propane dehydrogenation projects

raw material agreements are gradually signed

due to the high sulfur content of propane in domestic refineries and the relatively scattered supply, the raw material propane of propane dehydrogenation project mainly depends on imports. With the completion of a large number of propane dehydrogenation projects, whether the propane supply is sufficient or not most affects the nerves of market participants. However, with the vigorous development of the shale gas revolution, the global propane production has increased rapidly, eliminating this concern in the market

shale gas is rich in propane. With the accelerated exploitation of unconventional oil and gas such as shale gas in the world, there is a large potential supply of propane. In the past three years, the growth rate of propane exports in the United States has reached 136%, and the total export volume is expected to reach 3.5 million tons in 2014. The new ethane production capacity in the Middle East in the next few years will also reach 6.5 million tons. Even considering the new propane dehydrogenation capacity, experts estimate that there will be an excess of 2million tons of propane by 2015

due to the lucrative export of propane, North American enterprise and Targa resources are expanding propane export terminal facilities, followed by other companies. This makes the source of propane in China more secure. It is understood that at least three domestic propane dehydrogenation enterprises have signed long-term agreements with the United States on the supply of liquefied propane. It is reported that a propane dehydrogenation producer in East China has signed a contract of one ship per month from 2015 to 2017 with an American enterprise, and has signed a contract of one ship per February from 2018 with a European trader; A Tianjin trader and a Fujian enterprise have signed a long-term agreement with Targa of the United States for 7 and 5 years respectively. Every month and every February 1, we specialize in the production of universal testing machines, tensile testing machines, pressure testing machines, impact testing machines, friction and wear testing machines. All the testing machines we produce are one-stop service ships. The gradual signing of the long-term agreement will not only reassure domestic propane dehydrogenation enterprises, but also accelerate the launch of domestic propane dehydrogenation projects
