First of all, the consumption structure of butadiene in China has undergone great changes. Almost all of it was used to produce synthetic rubber since the early 1990s and gradually expanded to produce synthetic resins, thermoplastic elastomers, styrene-butadiene latex and other organic chemical products. It is the largest increase in consumption of ABS resin, SBS thermoplastic elastomer and styrene butadiene latex. With the increase in the production of butadiene in various consumer products, the demand for butadiene will also continue to increase. It is expected that by 2012, the total consumption of butadiene in China will reach 2.2 million tons.
Secondly, due to the increase in market demand and other reasons, the price of butadiene in domestic and foreign markets has increased. Especially since the beginning of this year, the price increase has been even greater. Domestic butadiene quotation was only 5,000 yuan/ton at the beginning of the year, and reached 12,000 yuan/ton in late August, which greatly increased the efficiency of manufacturers, and many companies started to build new butadiene. Alkene device.
Finally, butadiene production capacity has grown rapidly. On August 25th, the new butadiene plant newly built by Yangzi Petrochemical Company passed the final acceptance. The annual production capacity of this unit is 100,000 tons. With the original two sets of butadiene equipment, the annual production capacity of butadiene in Yangzi Petrochemical has reached 210,000 tons, which has become a domestic butadiene production process using dimethylformamide (DMF) process. The largest producer. In the past 10 years, domestic butadiene production has grown rapidly, and the original supply shortage has changed dramatically and will be completely reversed. In 1995, the output of butadiene in China was only 336 thousand tons, which increased to 591,000 tons in 2000 and reached 1.195 million tons in 2008. It is estimated that from 2009 to 2012, the domestic butadiene production capacity will increase by 1.06 million tons, and the total domestic production capacity will reach 2.78 million tons at that time, and the production capacity will not only meet the domestic production demand, but also have surplus. In the past, the production capacity and output of butadiene in China could not meet the actual domestic production demand, and it was imported in large quantities every year. At present, China’s butadiene products have already had a small amount of exports. In 2004, the export volume was 0.36 million tons and in 2008 it reached 36,000 tons.
China's butadiene production capacity will increase supply shortage will reverse
Due to the expansion of application fields and the increase in product prices, the butadiene production capacity in China has been continuously improved recently. Therefore, the contradiction in the long-term shortage of butadiene supply will be completely resolved, but there will also be the problem of excess production capacity.
