M'sabata yoyamba ya Novembala, Zhenhai Phase II ndi Tianjin Bohai Chemical Co., Ltd. zidagwiritsidwa ntchito molakwika chifukwa cha kutsika kwa mtengo wa styrene, kutsika kwamitengo, kutsika kwa miliri ku Jinling, m'chigawo cha Shandong, Kutsekedwa kwa Huatai kuti akonzere, ndipo kuyamba kwa zomera zapakhomo za propylene oxide kunatsika mpaka 70%.Komabe, kutsika kotereku sikunaletse kutsika kwa propylene oxide.Mtengo wa propylene oxide utatsika mpaka pafupifupi 8700 yuan/ton, mtengo wamadzimadzi wa chlorine wa zida zopangira zidakwera, Mothandizidwa ndi magetsi, Shandong Sanyue yachepetsa katundu wa mayunitsi ake.Pansi pa zopinga za mtengo wa propylene oxide multi process, zowonjezera zowonjezera zakhala zikuyenda bwino, ndipo malingaliro okonza mitengo adawukanso.Mtsinje wapansi siwowopsa kwambiri kuti ungadikire kutsika kosalekeza kwa propylene oxide.Kuwonjezeka kumatsatiridwa ndi kugula.Ma terminals ena akupanganso malonda nthawi ndi nthawi.Msika wamsika wayenda bwino, ndipo mtengo wa propylene oxide wasiya kutsika ndikuwonjezekanso.
Mu sabata yachiwiri, ndi kuchira kwa Sanyue unit katundu, akamaliza kukonza Huatai, ndi kutha kwa ulamuliro Dongying Guangrao, katundu Jinling pang'onopang'ono anabwerera mwakale, ndi zoweta propylene okusayidi chomera anayamba pang'onopang'ono kukwera pafupifupi 73%.Ma terminal adabwerera kuti adikire ndikuwona atangofunika kuwonjezeredwa kumapeto kwa sabata yoyamba.Popanda chiyembekezero chowonjezeranso sabata ino, msika unali wochepa pang'ono pothandizira mfundo zabwino, koma zipangizo za propylene ndi chlorine yamadzimadzi zonse zikukwera, ndipo propylene oxide inali muvuto la kukwera ndi kugwa, ndi kukwera kwa yaiwisi. zida, mtengo wongoyerekeza wa chlorohydrin udakakamizika kukwera ndi 100 yuan, ndipo msika wamsika udakhalabe wathyathyathya.Kumapeto kwa sabata, nkhani yakuti Shandong zomera zazikulu anali outsourcing propylene okusayidi analowa mu msika, ndipo msika maganizo analimbikitsidwa.Chomera cha Shandong Shida Shenghua cha propylene oxide chidasinthidwa, ndipo kumunsi kwa mtsinje kunali pafupi ndi kutulutsa kozungulira.Shandong Bluestar East idayamba, ndikugula mwachizolowezi.Chomera cha propylene oxide chidasunga chikondwerero chobweretsa bwino.Lamlungu lachiwiri, Shandong adayimira kutsika kwamitengo, ndipo msika udakwera pang'ono pokana kugulitsa.
Mu sabata yachitatu, msika unayamba pang'ono kumpoto.Pakalipano, pali mauthenga ambiri opanda kanthu mupropylene oxide msika.Ubwino wake ndi: Shandong Huan C Chomera, chifukwa cha mliri wa mliri, wachepetsa katundu wa mayunitsi ake;Sinochem Quanzhou ali ndi dongosolo kuchepetsa katundu, ndi malo kupereka kumsika ndi ochepa;Shandong Dachang akuyembekezeka kupitiriza kuchotsa propylene oxide;Kuchepetsa kupanga kwamakampani am'madzi am'madzi aku China.Zambiri mwazinthu zoyipa ndi mayunitsi atsopano: Gawo la Qixiang Tengda la propylene oxide likuyembekezeka kupanga zida, ndipo ndondomekoyi ikufunikabe chisamaliro;Pali mwezi kudyetsa dongosolo Taixing Yida chipangizo;Pakali pano, chakudya madzi klorini ndi propylene ali ofooka ntchito ndi zovuta kuthandizira mu nthawi yochepa;Kukhudzidwa ndi nyengo yopuma komanso mliri wamakampani, ntchito ya terminal imakhala yotsika nthawi zonse.M'kanthawi kochepa, zikuyembekezeka kuti msika wa propylene oxide ugwira ntchito mwamphamvu mothandizidwa ndi zinthu zabwino.M'tsogolomu, ngati mtengowo ukupitirizabe kukhala wovuta kuthandizira, propylene oxide idzakhalabe ndi chiyembekezo cha kuchepa kwa mphamvu.Mothandizidwa ndi mtengo wa ndondomeko yatsopanoyi, malo otsika ndi ochepa.M'tsogolomu, propylene oxide ikuyembekezeka kukhalabe ndi kugwedezeka pang'ono, ndi malo ochepa mmwamba ndi pansi.
