Kusintha kwa msika wa acetone mu August kunali cholinga chachikulu, ndipo pambuyo pa kukwera koopsa mu July, misika ikuluikulu ikuluikulu inakhalabe yogwira ntchito kwambiri ndi kusinthasintha kochepa.Ndi mbali ziti zomwe makampani adalabadira mu Seputembala?

Kumayambiriro kwa mwezi wa August, katunduyo anafika padoko monga momwe anakonzera, ndipo katundu wa padoko anawonjezeka.Kutumiza kwatsopano kwa mgwirizano, kutulutsa kwa fakitale ya phenol ketone, Shenghong Refining ndi Chemical sikungakonzeko kwakanthawi, ndipo malingaliro amsika akukakamizidwa.Kufalikira kwa zinthu zapamalo kwawonjezeka, ndipo eni ake akutumiza pamitengo yotsika.The terminal ndi kugaya makontrakitala ndi kuyembekezera pambali.
Pakati pa Ogasiti, zoyambira zamsika zinali zofooka, pomwe eni ake amatumiza motengera momwe msika uliri komanso kufunikira kochepa kuchokera kumafakitole omaliza.Osati zambiri zomwe zimaperekedwa mwachangu, mabizinesi a petrochemical adatsitsa mtengo wa acetone, kuchulukitsa phindu, ndikuwonjezera kudikirira ndikuwona.
Kumapeto kwa August, pamene tsiku lokhazikika likuyandikira, kukakamizidwa kwa malonda a katundu wapakhomo kunawonjezeka, ndipo malingaliro otumizira anawonjezeka, zomwe zinapangitsa kuchepa kwa zopereka.Katundu wam'doko ndi wosowa, ndipo ogulitsa zinthu kuchokera kunja amapereka mitengo yotsika komanso yofooka, ndi zotsatsa zolimba.Katundu wapakhomo ndi wapakhomo amapikisana kwambiri, ndi mafakitale ogulitsa zinthu ndikuwonjezera zotsika mtengo.Mabizinesi akutsika akupitilirabe kubweza, zomwe zimapangitsa kuti malonda amsika azikhala osasunthika komanso mabizinesi ang'onoang'ono.
Mbali yamtengo: Mtengo wamsika wa benzene weniweni ukukwera kwambiri, ndipo zomera zapakhomo zoyera za benzene ndizokhazikika.Pamene nthawi yobweretsera ikuyandikira, pangakhale chophimba chachifupi.Ngakhale kuti kufunikira kwina kunsi kwa mtsinje kukuyembekezeka kuwonjezeka, uku ndi kuyambiranso pang'ono pambuyo pa kuchepa kwakukulu kwa kufunikira kwakunsi kwa mtsinje.Chifukwa chake, ngakhale kufunikira kungabwerenso pang'ono, mtengo wamatchulidwe a benzene yoyera pakanthawi kochepa ukhoza kukhala pafupifupi 7850-7950 yuan/ton.
Mtengo wa propylene pamsika ukupitilirabe kutsika, ndipo mtengo wa propylene ukutsika mwachangu, ndikuchepetsa kupanikizika kwa msika komanso kufunikira kwa msika.Pakanthawi kochepa, pali malo ochepa kuti mtengo wa propylene uchepe.Mtengo wa propylene pamsika waukulu wa Shandong ukuyembekezeka kusinthasintha pakati pa 6600 mpaka 6800 yuan/ton.

Mtengo wogwira ntchito: Blue Star Harbin Phenol Ketone Plant ikukonzekera kuti iyambenso mwezi usanathe, ndipo Jiangsu Ruiheng Phenol Ketone Plant ikukonzekeranso kuyambiranso.Gawo lachiwiri la Bisphenol A Plant likhoza kupangidwa, zomwe zingachepetse kugulitsa kwakunja kwa acetone.Akuti chomera cha 480000 ton/chaka cha phenol ketone cha Changchun Chemical chikuyenera kukonzedwa pakati pa kumapeto kwa Seputembala, ndipo chikuyembekezeka kukhala masiku 45.Kaya chomera cha 650000 ton/chaka cha Dalian Hengli chidzayamba kugwira ntchito monga momwe zakonzedwera pakati mpaka kumapeto kwa Seputembala zakopa chidwi.Kupanga kwa mayunitsi ake othandizira bisphenol A ndi isopropanol kudzakhudza mwachindunji malonda akunja a acetone.Ngati chomera cha phenol ketone chikugwiritsidwa ntchito monga momwe adakonzera poyamba, ngakhale kuti chopereka chake chopereka acetone mu September ndi chochepa, padzakhala kuwonjezeka kwa kupezeka pambuyo pake.
Mbali yofunikira: Samalirani momwe chida cha bisphenol A chimapangidwira mu Seputembala.Gawo lachiwiri la chipangizo cha bisphenol A ku Jiangsu Ruiheng likukonzekera kuti liyambe kugwira ntchito, ndipo kuyambiranso kwa chipangizo cha Nantong Xingchen kuyenera kuyang'aniridwa.Kwa MMA, chifukwa cha zopangira zochepa, chipangizo cha MMA cha Shandong Hongxu chikuyembekezeka kuchepetsa kupanga.Chipangizo cha Liaoning Jinfa chikuyenera kukonzedwanso mu Seputembala, ndipo mkhalidwewo ukufunikabe chisamaliro china.Ponena za isopropanol, pakadali pano palibe dongosolo lomveka bwino lokonzekera ndipo pali zosintha zochepa pa chipangizocho.Kwa MIBK, Wanhua Chemical's 15000 ton/year MIBK plant ili pachimake ndipo ikukonzekera kuyambiranso kumapeto kwa September;Chomera cha 20000 ton/chaka ku Zhenyang, Zhejiang chikukonzekera kukonzedwa mu Seputembala, ndipo nthawi yake ikufunikabe kutsatiridwa.
Mwachidule, msika wa acetone mu Seputembala umayang'ana kwambiri pakusintha kwazomwe zimaperekedwa komanso zofunikira.Ngati kuperekera kuli kolimba, kumatha kukweza mtengo wa acetone, koma ndikofunikiranso kulabadira kusintha kwa mbali yofunikira.
