Esontweni lokuqala likaNovemba, isigaba seZhenhai II noTiannjin Bohai Chemical Co, Ltd. bebesebenza kabi ngenxa yokwehla ngentengo yeStyrene, ukwehla kwezindleko, isifundazwe saseShandong, i Ukuvalwa kwe-Huatai ngokulungiswa, kanye nokuqala kwezithelo ze-onide zasekhaya ze-oxide ze-oxide zehle zize zibe ngu-70%. Kodwa-ke, ukuqala kabusha okunjalo akuzange kuvikele ukuthambekela kwe-propelene oxide. Lapho intengo ye-oxide ye-oxide yehle cishe ngo-8700 yuan / ithoni, intengo ye-chlorine ewuketshezi yezinto zokwakha ezivuthiwe, ngaphansi kwethonya lesitshalo samandla, uShandong Sanyue wehlise umthwalo amayunithi awo. Ngaphansi kwezinkinga zezindleko zePropylene Oxide Enhlobonhlobo, ukuhlinzekwa okuphezulu kakhulu kuqhubeke ukuthandeka, futhi ubuhle bokulungiswa kwentengo buye bavuka futhi. I-Downstream ayiyona ingozi kakhulu ukulinda ukwehla okuqhubekayo kwe-oxye ye-oxide. Ukwanda kulandelwa ukuthenga. Amanye ama-terminals nawo enza ama-bargains ngezikhathi ezithile. Isimo semakethe sithuthukile, futhi intengo ye-oxide ye-oxide iyekile ukuwa yaphinde yaziwe.
Esontweni lesibili, ngokubuyiselwa komthwalo we-Sanyue Unit, ukuqedwa kokulondolozwa kukaHuatai, kanye nokuphela kokulawulwa kuka-Guangrao, umthwalo we-jinling we-juinling kancane ubuyela kokujwayelekile, futhi isitshalo sasekhaya se-onide oxide saqala kancane ukuze sikhuphuke saya ku-73%. I-terminal ibuyele ukuze ilinde futhi ibone ngemuva kokuthi idinga ukuphindisela emuva kwengxenye yesonto lokuqala. Ngaphandle kokulindela ukugcwaliswa okuqhubekayo kuleli sonto, imakethe ibifushane kancane ngokusekelwa kwamaphoyinti amahle, kepha izinto ezivuthiwe kanye ne-chlorine ewuketshezi zazikhuphuka, futhi i-oxide ye-propylene ibikhuphuka, futhi i-propelene oxide ibisenkingeni yokunyuka nokuwa, nokunyuka okuluhlaza Izinto zokwakha, izindleko zethiyori ze-chlorohydrin zaphoqeleka ukuba zikhuphuke ngo-100 yuan, futhi umkhathi wemakethe wahlala eyisicaba. Ekupheleni kwesonto, izindaba ezithi ama-Shandong izitshalo ezinkulu ezazikhipha i-oxide egcwele emakethe, futhi isimo sengqondo semakethe sakhuphuka. Isitshalo sikaShandong Shida Shengghua i-onide isitshalo se-onide sagcwala, kanti phansi komfula kwakuseduze nokungaphandle okuzungezile. I-Shandong Bluestar East yaqala phezulu, futhi ithengwe ngokujwayelekile. Isitshalo se-oxide ye-propylene oxide sagcina umkhosi wokulethwa okubushelelezi. NgeSonto lesibili, uShandong wamelela iqoqo eliphansi lesitshalo, futhi imakethe yakhuphuka kancane ngaphansi kwesimo sokungabaza ukuthengisa.
Esontweni lesithathu, imakethe yaqala ukuphakama kancane enyakatho. Njengamanje, kunemiyalezo eminingi engenalutho kuImakethe ye-oxide ye-propylene oxide. Izinzuzo yilezi: uShandong Huan C Isitshalo, ngaphansi kwethonya lesimo sempi, sehlise umthwalo amayunithi alo; ISinochem Quanzhou unecebo lokunciphisa umthwalo, futhi ukunikezwa kwendawo emakethe kukhawulelwe; UShandong Dachang kulindeleke ukuthi aqhubeke nokukhipha i-propelene oxide; Ukuncishiswa kokukhiqizwa kwe-emboni yasemanzini yasemanzini yasemanzini. Amanani amaningi amabi amayunithi amasha: qixiang tengda's propylene onivide Unit kulindeleke ukuthi akhiqize izinto zokwakha, futhi inqubo ethile isadinga ukunakwa; Kunohlelo lokuphakelwa kwanyanga zonke lwedivayisi ye-taixing Yida; Njengamanje, i-ompory uketshezi chlorine ne-propenene kusebenza okubuthakathaka futhi kunzima ukusekela esikhathini esifushane; Kuthintwe yisimo sesikhathi se-off-sonyaka kanye nesifo semboni, umsebenzi we-terminal uhlala uphansi. Esikhathini esifushane, kulindeleke ukuthi imakethe ye-oxide ye-propylene oxide izosebenza iqine kancane ngaphansi kokusekelwa kokuhlinzekwa okuhle. Ngokuzayo, uma izindleko ziqhubeka zinzima ukusekela, i-propelene oxide isazobe sekwehliswa ingcindezi. Isekelwa yizindleko zenqubo entsha, isikhala sokwehla silinganiselwe. Ngokuzayo, i-propelene oxide kulindeleke ukuthi ilondoloze ukudlidliza okuncane, ngesikhala esincane phezulu naphansi.
