On July 28, bureau of environment of organisms' habits of Zi rich town releases “20 of Inc. of chemical industry of Teng Da of Zi Bo Qixiang 10 thousand tons / year annulus of ” of project of suitable anhydride extend judges fair show: Teng Dashun anhydride has Qi Xiang produce can be 200 thousand tons / year, to produce can big suitable anhydride unit: It is to built go into operation 2013 respectively 150 thousand tons / year environmental protection new material (PBS) first phase arranges anhydride device 100 thousand tons, built go into operation 2015 2 period a device of 50 thousand tons of suitable anhydride, built go into operation 2017 2 period device of another 50 thousand tons of suitable anhydride. Above 3 period suitable anhydride device all is used production of butane oxidation law arranges anhydride, at present device moves normally, device is used up reach the index such as product quality to already all reached domestic banner level.

Arrange anhydride, full name arranges Ding Xi 2 acid anhydride, call Ma Lai acid anhydride again, it is serious organic industrial chemicals, tens of planting wait in synthetic material, coating, organic acid there is very wide application in the industry, also be agent of a kind of important epoxy resin solidify. Fat annulus a group of things with common features the means of main hot solidify of epoxy resin namely acid anhydride solidify. Agent of acid anhydride solidify is commonly usedly anhydride of suitable anhydride, 6 hydrogen benzene, methylic acid anhydride of anhydride of 4 hydrogen benzene, chloric second, its volatile small, noxiousness is small, excitant to cutaneous small also, and its operating period is long, the operation is convenient also. According to Qi Xiang Tengda develops a program, combinative company's existing technology, raw material, public project is relied on, capital and market dominant position, inc. of chemical industry of Qi Xiang Teng Da drafts 200 thousand tons to invest construction / year device of suitable anhydride extend, can realize entire plant eventually 400 thousand tons / year the scale of production that arrange anhydride. Name of project of 　 of project general situation: Inc. of chemical industry of Teng Da of Zi Bo Qixiang 200 thousand tons / year 　 of project of suitable anhydride extend builds an unit: 　 of Inc. of chemical industry of Teng Da of Zi Bo Qixiang builds a place: Garden of industry of Qi Lu chemistry of city of Shandong Zi rich, category of industry of the 　 inside plant area of Qi Xiang Teng Daxin: Raw material of C2614 organic chemistry makes 　 build property: Extend 　 covers an area of an area: 27.5 mus of 　 build cycle: Project of 23 months 　 invests: Always invest 1.25 billion yuan, among them environmental protection invests 69 million yuan, 5.51% what hold total investment. This second construction content basically includes two to produce all can be 100 thousand tons / year unit of the production that arrange anhydride (include oxidation unit, dissolvent to draw unit, form piece unit, tail gas handles unit to wait for a part) , the environmental protection establishment of form a complete set, public project and support features. Extend project uses Tianjin Bo to change the technology with engineering mature and advanced limited company, through butane combustion technology will butane is changed into suitable anhydride product, suitable anhydride crop is 200 thousand tons / year. Institute of the existing plant that arrange anhydride is used butane comes from at upper reaches 450 thousand tons / year dehydrogenation of hydrocarbon of low carbon alkyl makes alkene and integrated interest expenditures look place produces raw material carbon the earning after 4 classics enrage minute of device to depart, this second extend arranges anhydride plant institute to use raw material butane comes from Yu Tongjian 200 thousand tons / year different Ren mellow project (350 thousand tons / year butene device) , principle of the others craft and moving parameter and existing project are invariant. Qi Xiang Teng Da has unit: Qi Xiang Teng Da has two plant area at present, one is in area of the eastpart part of industrial district of Qi Lu chemistry (old plant area) , another is in area of horn of southwest of industrial district of Qi Lu chemistry (new plant area) old plant area has MTBE device to build project, butene separate project, 20 thousand tons / year project of Jia Yi ketone, 20 thousand tons / year MTBE splitting decomposition makes different butene item, 80 thousand tons. New plant area has a project to include to produce per year 100 thousand tons of butadiene projects, 150 thousand tons / year butadiene unit transforms extend project, produce per year 70 thousand tons of rare earth butadiene rubber project, produce per year new material of 150 thousand tons of environmental protection (PBS) project, 450 thousand tons / year hydrocarbon of low carbon alkyl makes alkene and integrated profit. In build a project to be 700 thousand tons / year propane dehydrogenation project, 400 thousand tons / Nian Shuding alcohol and form a complete set 200 thousand tons / year MMA project, 50 thousand tons / year project of different butene unit, 300 thousand tons / year project of annulus oxygen propane, 70 thousand tons / year; Build a project to be 400 thousand tons together / year project of extend of fourth nitrile latex, 200 thousand tons / year different Ren mellow project (350 thousand tons / year butene device) .
