According to Guo Shimin's introduction, maleic anhydride products have a market and development space in some regions despite the fact that the maleic anhydride products are provided for on a large scale. Although viewed from the whole country, it is surplus, but there are imbalances in production and demand in some regions of the country. For example, Changzhou Yabang has already had 150,000 tons/year of production capacity, but it is not enough for itself, and it is outsourced; there is no maleic anhydride production enterprise in South China. Large resin use, if there is liquefied gas resources, consider n-butane maleic anhydride. However, areas such as Henan, where the raw material benzene resources are insufficient, are not suitable for implementation. In some areas, the production of maleic anhydride plants has been suspended due to the shortage of raw materials.
Zhuo Chuangxiu Yufeng Yu believes that this year's new maleic anhydride production capacity will be diluted by new demand. Although Shanxi Gaoyi, Shandong Jiazhou, and Nanjing Zhongteng maleic anhydride plants are expected to be put into operation this year, there are also projects for downstream production of maleic anhydride, and Shanxi's three-year annual production of 75,000 tons of 1,4-butanediol (BDO) is expected to start production this year; Shandong Zibo Jia Zhou Chemical Co., Ltd. will be completed at the end of the year will produce 50,000 tons of maleic anhydride BDO device; Zhejiang, an enterprise with an annual output of 50,000 tons BDO device will be put into operation in July this year, when will increase the demand for maleic anhydride. Taken together, the new production capacity of maleic anhydride exceeded 100,000 tons in 2011, and the new demand was also above 100,000 tons. There will not be much change in market supply and demand.
Most of the maleic anhydride devices in China use the benzene oxidation process, and only three sets of n-butane oxidation maleic anhydride devices. The main raw material of China's maleic anhydride is coking benzene, and the price of crude oil has risen, which has driven the rise of coking benzene. At present, the transaction price in East China has reached 7,400 yuan/ton, and there is not much supply in the market, and the suppliers are reluctant to sell. The market price of coking benzene will be high in the future. Consolidate. According to Guo Shimin, although the normal butane production process replaces the traditional benzene oxidation process, the carbon 4 resources are generally not available to the enterprises, and the replacement process is still relatively long. The benzene oxidation production process is still a relatively long period of time. There will be an old maleic anhydride enterprise that has its own benzene resources and processing capacity and can start an maleic anhydride project.
It is reported that from 2011 to 2012, the production capacity of maleic anhydride will exceed 500,000 tons/year, and most of the production capacity will be released in 2012. At this time, the issue of excess capacity will become more prominent. Experts said that many downstream products of maleic anhydride, such as γ-butyrolactone, tetrahydrofuran, tartaric acid, succinic acid and tetrahydrophthalic anhydride, are all fine chemical products with good prospects for development and utilization, and should increase the lengthening of the maleic anhydride industrial chain. To achieve product serialization, refinement, enhance the economic benefits of production devices and the ability to withstand market risks.
Guo Shimin, secretary general of the National Maleic Anhydride Industry Cooperation Group, said in an interview with reporters that the current profit margin of 400 yuan per ton of maleic anhydride has attracted many companies to build or expand maleic anhydride projects. In recent years, a large amount of new production capacity is about to emerge. In 2011, the total domestic maleic anhydride production capacity is expected to reach 1.05 million tons, and the consumption will be close to 650,000 tons. From the perspective of total production and demand, it has far exceeded supply. Can not be launched, can not statically see the overall relationship between excess production and demand, but to see their own production and regional balance.
