Ukulungiswa kobubanzi bemakethe ye-acetone ngo-Agasti kwakuyiyona nto okugxilwe kuyo kakhulu, futhi ngemva kokukhuphuka okubukhali ngoJulayi, izimakethe ezinkulu ezivamile zigcine amazinga aphezulu okusebenza ngokuguquguquka okulinganiselwe.Yiziphi izici imboni ezinake kuzo ngoSepthemba?

Ekuqaleni kuka-Agasti, impahla yafika echwebeni njengoba kwakuhleliwe, futhi inani lempahla yasechwebeni landa.Ukuthunyelwa kwenkontileka entsha, ukukhishwa kwefekthri ye-phenol ketone, i-Shenghong Refining ne-Chemical ngeke kuqhube ukulungiswa okwesikhashana, futhi umuzwa wemakethe ungaphansi kwengcindezi.Ukusatshalaliswa kwempahla yamabala kunyukile, futhi abanikazi bathumela ngemikhumbi ngamanani aphansi.Itheminali igaya izinkontileka futhi ilinde eceleni.
Maphakathi no-Agasti, izisekelo zemakethe zazibuthakathaka, abanikazi bemikhumbi behamba ngokuvumelana nezimo zemakethe kanye nesidingo esilinganiselwe esivela ezimbonini zokugcina.Azikho izipesheli eziningi ezisebenzayo, amabhizinisi e-petrochemical ehlise intengo yeyunithi ye-acetone, akhulisa ingcindezi yenzuzo, futhi andisa nomuzwa wokulinda nokubona.
Ekupheleni kuka-August, njengoba usuku lokukhokha lusondela, ingcindezi ezinkontilekeni zempahla yasekhaya yanda, futhi umuzwa wokuthumela ngemikhumbi wakhula, okuholele ekwehleni kwezipesheli.Izimpahla zasechwebeni ziyashoda, futhi abahlinzeki bezinsiza zokungenisa banikeza amanani aphansi nabuthaka, ngokunikezwa okuqinile.Izimpahla zasekhaya nezamachweba ziqhudelana kanzima, nezimboni ezigayayo ezigayayo futhi zikhuphule okunikezwayo okunenani eliphansi.Amabhizinisi asezansi ayaqhubeka nokuba nempahla, okuholela ekuhwebeni kwezimakethe kanye nokuhweba okuyisicaba.
Uhlangothi lwezindleko: Intengo yemakethe ye-benzene emsulwa iyenyuka kakhulu, futhi umthwalo wezitshalo zasekhaya ze-benzene ezihlanzekile uzinzile.Njengoba isikhathi sokulethwa sisondela, kungase kube nokumboza okufushane.Nakuba isidingo esithile esingaphansi komfula kulindeleke ukuba sikhuphuke, lokhu kuwukuphindaphinda okuncane kuphela ngemva kokwehla okukhulu kwesidingo esiphelele somfula.Ngakho-ke, nakuba isidingo singase sikhuphuke kancane, intengo yesithenjwa ye-benzene emsulwa esikhathini esifushane ingaba cishe ku-7850-7950 yuan/ton.
Intengo ye-propylene emakethe iyaqhubeka nokwehla, futhi intengo ye-propylene yehla ngokushesha, inciphisa ingcindezi ekuhlinzekeni kwemakethe kanye nesidingo.Esikhathini esifushane, kunendawo elinganiselwe yokuthi intengo ye-propylene yehle.Intengo ye-propylene emakethe enkulu yaseShandong kulindeleke ukuthi ishintshe phakathi kuka-6600 kuya ku-6800 yuan/ton.

Izinga lokusebenza: I-Blue Star Harbin Phenol Ketone Plant ihlelelwe ukuqala kabusha ngaphambi kokuphela kwenyanga, futhi I-Jiangsu Ruiheng Phenol Ketone Plant nayo ihlelelwe ukuqala kabusha.ISigaba II esisekela Isitshalo se-Bisphenol A singase sifakwe ekukhiqizeni, okuzonciphisa ukuthengiswa kwangaphandle kwe-acetone.Kubikwa ukuthi i-480000 ton/year phenol ketone plant ye-Changchun Chemical ihlelelwe ukunakekelwa maphakathi no-September ngasekupheleni, futhi kulindeleke ukuthi ihlale izinsuku ezingu-45.Ukuthi imboni ye-Dalian Hengli engamathani angu-650000/ngonyaka izoqaliswa yini njengoba kuhlelwe maphakathi no-September sekudonse ukunaka okukhulu.Ukukhiqizwa kwamayunithi ayo asekela i-bisphenol A kanye ne-isopropanol kuzothinta ngokuqondile ukuthengiswa kwangaphandle kwe-acetone.Uma isitshalo se-phenol ketone sisetshenziswa njengoba bekuhleliwe ekuqaleni, nakuba umnikelo waso ekunikezeni i-acetone ngo-September ulinganiselwe, kuzoba nokwanda kokunikezwa esikhathini esizayo.
Uhlangothi lwesidingo: Naka isimo sokukhiqizwa kwedivayisi ye-bisphenol A ngoSepthemba.Isigaba sesibili somshini we-bisphenol A e-Jiangsu Ruiheng sihlelelwe ukuthi siqale ukusebenza, futhi ukuqaliswa kabusha kwedivayisi ye-Nantong Xingchen nakho kudinga ukugadwa.Ku-MMA, ngenxa yezinto ezingavuthiwe ezilinganiselwe, idivayisi ye-MMA ye-Shandong Hongxu kulindeleke ukuthi yehlise ukukhiqizwa.Umshini we-Liaoning Jinfa uhlelelwe ukunakekelwa ngo-September, futhi isimo esithile sisadinga ukunakwa okwengeziwe.Ngokuqondene ne-isopropanol, okwamanje alukho uhlelo olucacile lokulungisa futhi kunezinguquko ezimbalwa kudivayisi.Ku-MIBK, imboni ye-MIBK ye-Wanhua Chemical engu-15000 ton/ngonyaka isesimweni sokuvala shaqa futhi ihlela ukuqalisa kabusha ngasekupheleni kukaSepthemba;Imboni ye-20000 ton/ngonyaka e-Zhenyang, e-Zhejiang ihlelelwe ukunakekelwa ngoSepthemba, futhi isikhathi esiqondile sisadinga ukulandelwa.
Kafushane, imakethe ye-acetone ngoSepthemba izogxila ekushintsheni kwesakhiwo sokuhlinzeka nesidingo.Uma ukunikezwa kuqinile, kungase kwenyuse intengo ye-acetone, kodwa futhi kuyadingeka ukunaka izinguquko ohlangothini lwesidingo.
