this year, Ma market has been rising, up to now China maleic anhydride prices reached 9000-9500 yuan / ton, compared with the beginning of 64.3%. or maleic anhydride reasons for the rise of three points, the first is affected by the upstream raw material benzene pull, followed by lower unsaturated resin manufacturers is boosted, finally the overall operating rate is low, the supply of good support.

Although this year the maleic anhydride market gains gratifying, but benzene and butane profits polarization, is the so-called moon curved as Kyushu, a few happy tears.

The process route of maleic anhydride in our country mainly by benzene oxidation and n-butane oxidation of the two.

The benzene oxidation process because of maleic anhydride is used earlier, early raw materials, so a large proportion in our country. Derrick Henry In 2016 China maleic anhydride production capacity of about 2 million tons, of which about 1 million 350 thousand tons of benzene to maleic anhydride, maleic anhydride – butane accounted for 67.5%, about 650 thousand tons, accounting for 32.5%., but in recent years, the high price of raw materials, the oxidation of benzene to maleic anhydride by cost increase, serious business losses, low operating rate, many of the old idle parking device. asics gel lyte 5 hombre While the cost method of n-butane current than benzene low 3000 yuan per ton, the overall profits. The development and promotion of law began in seven and 80s, with China in recent years, the west east gas surplus, downstream of n-butane sufficient supply of low price, replaced by butane oxidation device and method of benzene launched device to accelerate the pace of.

After 2010 China butane method maleic anhydride device rely on low cost to usher in the tide of construction, Shandong Qixian Tengda chemical in 2014 100 thousand tons of butane maleic anhydride plant put into production, the same year in Zhejiang, Jiangsu, Yizheng Jiangshan chemical fiber and Shandong Linyi yongshunda chemical butane device have been put into production, butane to maleic anhydride production method in 2014 after a moment expanded to 400 thousand tons. This year, Tengda Qi Xiang and a set of 50 thousand tons of butane plant put into operation, there is a set of 50 thousand tons of equipment commissioning plans next year, there will be 200 thousand Qixian tons of production capacity to become the largest manufacturer of maleic anhydride.

In addition to Qixian Tengda chemical industry, according to the online statistics, 2017 is about 550 thousand tons of butane projects under construction or proposed. Nike Free Run 5.0 homme At present, according to Wen Jiangshan chemical 50 thousand tons of equipment in the construction, the other 100 thousand tons of equipment still planned. Deondre Francois College Jersey Liaoning Yuan Li Petrochemical 120 thousand tons of butane devices currently has almost completed, Inner Mongolia Jiajing coal chemical 100 thousand tons of butane in 2013 has already started, but there is no production news. Changzhou xinrixin materials 60 thousand tons of equipment to start in August this year, Tianjin Xinyang Technology device 120 thousand tons of maleic anhydride in April of this year the eia. Asics Gel Lyte 3 Femme You can imagine, when these projects are all put into production, market saturation, benzene device will have a place to live in.

In addition to the new project, some enterprises are quietly benzene method device changes original butane process. Canada Goose Constable Parka Zhejiang Huachen energy is proposed as early as in 2009 40 thousand tons of benzene anhydride project has been completed. Nike Roshe Run Motif Homme Another Changmao biochemical also put 20 thousand tons of n-butane to maleic anhydride by benzene substitution project in September last year. And currently has a production capacity of 120 thousand tons of Changzhou Yabang chemical device in addition to the new investment Xinyang Technology, but also the beginning of the year for the 40 thousand tons of benzene by maleic anhydride project.

In addition to the cost of pressure on the formation of unitbenzene maleic anhydride method, environmental protection policies also have a greater resistance to the. nike air jordan 4 mujer In recent years, our country not only to enjoy the benefits of economic development, but also to experience the profound consequences of increasingly serious pollution. New Balance 373 męskie This year the national implementation of the most stringent environmental policy, the central environmental inspectors gradually to polluting chemical enterprises to carry out the transformation. Canotte Basket As everyone knows, styrene maleic anhydride method is not only costly, but also because of the use of raw materials of benzene, there is a big disadvantage in environmental protection.
