Overcapacity, exacerbated by loss of benzene to maleic anhydride method

Overcapacity situation upgrade , benzene France maleic anhydride growing losses , the loss of domestic production continues to rise. From 2010 to 2013 , maleic anhydride production capacity increased significantly , but the yield is now up slowly. On the one hand , the domestic law of maleic anhydride is still mainly benzene , and the rising cost pressures led some maleic anhydride plant can not properly started , the loss of production capacity on a yearly basis ; on the other hand , unsaturated resin market expansion is relatively slow , exacerbating the maleic anhydride oversupply situation. Among them, some manufacturers feel Shanxi, Jiangsu, increasing the operating pressure and a lot of benzene, maleic anhydride plant in France , said 2014 will make a major adjustment . In addition , Shandong , Zhejiang, new capacity to be released.Masking tape

Among Shandong Zibo Qi Xiang Tenda Chemical Corporation invested in the construction of 100,000 tons of maleic anhydride ( maleic anhydride ) at the end of October 2013 the project construction is completed, 11 November and put to trial began recently qualified smooth output maleic anhydride products to achieve a successful feeding drive . Upon examination, the production of maleic anhydride product purity of 99.97% , fully meet the standards for gifted class . The company will further improve the relevant process parameters to debug , optimize and improve the level of production of plant operation . This means the company carbon material remaining four groups divided into n-butane feedstock , production process using butane oxidation , compared to traditional benzene oxidation process, with better quality , more environmentally friendly production process, lower production costs other advantages. Commissioning of the project to achieve the comprehensive utilization of resources, carbon four companies to further enrich the company's industrial chain, and the company has a low-carbon alkane dehydrogenation and refining of raw materials utilization project done , will further enhance the company's economic efficiency and overall competitiveness .Wholesale masking tape

Zhejiang Jiangshan Chemical Co., Ltd. invested an annual output of 80,000 tons of maleic anhydride and derivatives integration project officially started in June 2011 , the planned duration of 31 months. Currently the project has been Sellotapecompleted and infrastructure were put to trial , as of December 3, 2013 , all projects devices ( liquefied petroleum gas separation unit , maleic anhydride production plant , BDO cogeneration unit ) are output of qualified products, superior product quality to meet grade standards. Follow-up will be put to trial for further linkage to optimize the process parameters to improve , gradually increase the plant load . Maleic anhydride and its derivatives in the integration project based on n-butane LPG group was divided into raw materials used by the U.S. Huntsman 's technology to produce maleic anhydride , the British David 's technology cogeneration BDO, GBL, THF , etc. with products of good quality , environmental protection and other advantages of the production process . The project is the company to enter the petrochemical industry , the first project to develop coastal resources , help enrich the company's industrial chain , to change the situation of a single company's products .Washi tape
