Ngesonto lokuqala likaNovemba, i-Zhenhai Phase II kanye ne-Tianjin Bohai Chemical Co., Ltd. asetshenziswe kabi ngenxa yokwehla kwenani le-styrene, ukwehla kwengcindezi yezindleko, ukwehla kokulawula ubhubhane e-Jinling, eSifundazweni SaseShandong, ukuvalwa kwe-Huatai ukuze ilungiswe, kanye nokuqaliswa kwezitshalo ze-propylene oxide zasekhaya zehla cishe ngama-70%. Kodwa-ke, ukuqala okuphansi okunjalo akuzange kumise ukwehla kwe-propylene oxide. Lapho intengo ye-propylene oxide yehla yaya cishe ku-8700 yuan/ton, intengo ye-chlorine ewuketshezi yezinto zokusetshenziswa yenyuka, Ngaphansi kwethonya lesikhungo samandla, i-Shandong Sanyue yehlise umthwalo wamayunithi ayo. Ngaphansi kokuvinjelwa kwezindleko ze-propylene oxide multi process, ukunikezwa okuphezulu kuye kwaqhubeka nokuba kuhle, futhi umqondo wokulungiswa kwamanani ukhuphuke futhi. Umfula ongezansi awunabungozi kakhulu ukulinda ukwehla okuqhubekayo kwe-propylene oxide. Ukwenyuka kulandelwa ukuthengwa. Amanye amatheminali nawo enza ama-bargains ngezikhathi ezithile. Isimo semakethe sesithuthukile, futhi intengo ye-propylene oxide iyekile ukwehla futhi yaphinde yakhuphuka.
Ngesonto lesibili, ngokutholwa komthwalo weyunithi ye-Sanyue, ukuphothulwa kokugcinwa kwe-Huatai, nokuphela kokulawula kuka-Dongying Guangrao, umthwalo kaJinling kancane kancane wabuyela kokujwayelekile, futhi isitshalo sasekhaya se-propylene oxide saqala ukukhuphuka kancane safinyelela cishe ku-73%. Itheminali ibuyile ukuze ilinde futhi ibone ngemuva kokuthi ivele idinga ukugcwaliswa engxenyeni yakamuva yeviki lokuqala. Ngaphandle kokulindela ukuqhubeka nokugcwaliswa kuleli sonto, imakethe ibishoda kancane ekusekeleni amaphuzu amahle, kepha izinto ezingavuthiwe i-propylene ne-chlorine ewuketshezi zombili bezikhuphuka, kanti i-propylene oxide yayisenkingeni yokukhuphuka nokuwa, Ngokukhuphuka kwezinto zokusetshenziswa, izindleko zethiyori ze-chlorohydrin zaphoqeleka ukuthi zikhuphuke nge-100 yu emakethe yahlala iphansi. Ekupheleni kwesonto, izindaba zokuthi izitshalo ezinkulu zaseShandong bezikhipha i-propylene oxide zangena emakethe, futhi isimo sengqondo semakethe sakhula. Isitshalo se-propylene oxide sika-Shandong Shida Shenghua salungiswa kabusha, futhi umfula ongezansi wawuseduze nokukhishwa kwemisebenzi okuzungezile. I-Shandong Bluestar East iqalile, futhi ithengwe ngokujwayelekile. Isitshalo se-propylene oxide sigcine umkhosi wokulethwa oshelelayo. NgeSonto lesibili, iShandong imele inani eliphansi lesitshalo, futhi imakethe yenyuka kancane ngaphansi kwesimo sokungabaza ukuthengisa.
Ngesonto lesithathu, imakethe yaqala ukuba phezulu kancane enyakatho. Njengamanje, kunemiyalezo eminingi engenalutho ku-imakethe ye-propylene oxide. Izinzuzo yilezi: I-Shandong Huan C Plant, ngaphansi kwethonya lesimo sobhubhane, inciphise umthwalo wamayunithi ayo; I-Sinochem Quanzhou inohlelo lokunciphisa umthwalo, futhi ukunikezwa kwendawo emakethe kulinganiselwe; I-Shandong Dachang kulindeleke ukuthi iqhubeke nokukhipha i-propylene oxide; Ukwehliswa kokukhiqizwa kochungechunge lwemboni yegobolondo lasolwandle lwaseChina. Iningi lamaphuzu amabi amayunithi amasha: Iyunithi ye-propylene oxide ye-Qixiang Tengda kulindeleke ukuthi ikhiqize izinto, futhi inqubo ethile isadinga ukunakwa; Kunohlelo lwanyanga zonke lokuphakela idivayisi ye-Taixing Yida; Njengamanje, i-chlorine ye-feed liquid kanye ne-propylene isebenza ngokubuthakathaka futhi kunzima ukuyisekela ngesikhathi esifushane; Ethintwa yisimo se-off-season kanye nobhubhane lwemboni, umsebenzi wetheminali uhlala uphansi. Esikhathini esifushane, kulindeleke ukuthi imakethe ye-propylene oxide izosebenza kancane kancane ngaphansi kokusekelwa kokuhlinzekwa okuvumayo. Esikhathini esizayo, uma izindleko ziqhubeka zinzima ukusekela, i-propylene oxide isazoba nokulindela ukwehla kwengcindezi. Ngokusekelwa izindleko zenqubo entsha, isikhala sokwehla silinganiselwe. Ngokuzayo, i-propylene oxide kulindeleke ukuthi igcine ukudlidliza okuncane, kube nesikhala esincane phezulu naphansi.
