Le khasiImakethe ye-oxide ye-propylene oxide"UJinjiu" waqhubeka nokukhuphuka kwawo kwangaphambilini, futhi imakethe yaphuka nge-yuan eyi-10000 (Inani lamathoni, okufanayo naphansi). Ukuthatha imakethe ye-Shandong njengesibonelo, intengo yemakethe yasuka yaba ngu-10500 ~ 10600 yuan ngoSepthemba 15, up cishe 1000 yuan kusukela ngasekupheleni kuka-Agasti. NgoSepthemba 20, yawa emuva cishe ngo-9800 yuan. Ngokuzayo, uhlangothi lokuhlinzekwa kulindeleke ukuthi lukhule, isisusa se-Peak Special asinamandla, futhi i-propylene oxide iguquguquka ngo-10000 yuan.
Ukukhuphuka kwe-proplemade oxide Unit Restart
Ngo-Agasti, ingqikithi yama-8 amasethi we-propylene oxide amayunithi afakwa ngaphezulu eChina, ebandakanya inani eliphelele lamathani ayi-1222000 kanye nokulahleka okuphelele kwamathani angama-61500. Ngo-Agasti, umphumela we-porppene oxide esitshalweni sama-2093200, ezansi nenyanga engu-2.17% ngenyanga, kanye nezinga lokusetshenziswa kwamakhono kwakungu-70.83%.
NgoSepthemba, iSinochem Quanzhou Peppene Oxide Unit yavalwa ukulungiswa, iTianjin Bohai Chemical, eguqukayo, ama-Shandong Huatai namanye amayunithi aqaliswa ngokulandelana, futhi iyunithi le-jinling lehliswe ngengxenye yokusebenza komthwalo. Njengamanje, inani elisebenzayo le-oxide ye-oxide lisondele kuma-70%, liphansi kancane kunalokho ngo-Agasti.
Esikhathini esizayo, uShandong Daze's 100000 T / Iyunithi uzoqala ukukhiqizwa ngasekupheleni kukaSepthemba, kanti uphiko lwe-Jincheng Petrochemical's 300000 T / Uphiko kulindeleke ukuthi lubekwe ekukhiqizweni ngasekupheleni kukaSepthemba; Izitshalo zeJinling ne-Huatai zibuyela ekukhiqizweni kwesinyathelo ngesinyathelo. Uhlangothi lokuhlinzekwa lukhula ikakhulukazi, futhi abathengisi bathembekile kakhulu. Kulindelwe ukuthi imakethe ye-oxide ye-propylene oxide izokhombisa umkhuba obuthakathaka we-stalemate ngaphansi kokwanda kokuhlushwa okuthengwayo, kube nengozi encane ephansi.
Ukuxhaswa okubonakalayo okuvuselelwayo kwe-propLene oxide kulindeleke kube nzima
Ngezinto zokwenziwa ezikhuphukayo ze-propylene ne-chlorine ewuketshezi, yize "jinjiu" ziboshwe ngegagasi lemakethe ekhuphukayo, kulindeleke ukuthi kube lula ukuwela emakethe yesikhathi esizayo, okuzoba nzima ukwakha idonsela elinamandla phansi komfula.
NgoSepthemba, intengo ye-propylene, impahla ekhuphukayo, iyaqhubeka nokukhuphuka ethukile, nayo enikeze ukwesekwa okuqinile kwemakethe ye-propylene oxide emakethe. UWang Quanping, unjiniyela omkhulu weShandong Kenli Petrochemical Group, uthe ukunikezwa kwasekhaya kwe-propylene kuhlala kuqinile, ngokusebenza okusobala enyakatho-ntshonalanga, ephakathi nendawo yasempumalanga yeChina. Ngaphezu kwalokho, amanye amadivaysi esondlo aphansi kwe-propelene, njengeTianjian Butyl Octanol, i-Dagu Epoxy Pratone, kanye ne-Kroll acrylonitrite, aqale kabusha ukwakhiwa. Ngakho-ke, ukufunwa kwemakethe kuqhutshwe phezulu, amabhizinisi we-propylene abelokhu ethengisa ngokushelela, futhi okuphansi kukhishwe amanani entengo aqhutshwa phezulu.
Ngokombono wokusebenza kweyunithi, ngakolunye uhlangothi, amayunithi we-xintai e-petrochemical kanye ne-properlene aqaliswa kabusha, kepha umthelela wawunqunyelwe ngenxa yokubambezeleka okuvamisile. Ngasikhathi sinye, amanye amakhono amasha okukhiqiza e-Propane Dehydrogenation ku-Phylene eShandong afakwa ngaphansi kokulindelekile, futhi ukunikezwa okuphelele kwakuyinto etholakalayo. Ngakolunye uhlangothi, esikhathini esizayo esiseduze, amanye amayunithi amakhulu enyakatho-ntshonalanga avaliwe ukuze alungiswe, futhi ukuqala kwe-propelene enyakatho-ntshonalanga kwehle ku-73.42%. Ukusakazwa kwezimpahla ze-peripheral poplene kuncishisiwe kakhulu. Ngaphezu kwalokho, ezinye izitshalo eziseNyakatho-Ntshonalanga zigcinile isidingo se-propelene ukukhiqizwa kwangaphandle, kanye nokunikezwa kwe-peripheral propylene kuqiniswe kakhulu.
Ngokuzayo, umthwalo weyunithi wamabhizinisi we-proppene uzinzile, futhi akukho okulindelwe izinguquko ezibalulekile ekunikezelweni kwe-propylene. Izifunda ezihlanzekile ze-Shandong ne-East China zisazogcina ukunikezwa okuqinile. Phansi emfuleni kuvame ukuba buthaka nepuleti, kucindezela umdlandla wokuthenga we-propylene waya phansi. Ngakho-ke, imakethe yamanje ye-propelene isesimweni sokuhlinzekwa okubuthakathaka nokufunwa, kepha i-octanol ephansi, i-acrylene oxide, i-acrylonitriterile kanye nezinye izimboni ikhuphule umthwalo yazo, futhi uhlangothi lwemfuno oluqinile lusenokusekelwa okuthile. Kulindelwe ukuthi intengo elandelayo ye-proplene izoshintshana kububanzi obuncane, ngokunyuka okulinganiselwe nokuwa.
Enye into eluhlaza ebonakalayo, i-chlorine ewuketshezi, isidlali esikhulu emakethe. Ivolumu yokuthengisa yangaphandle yeminye imishini yamafektri amakhulu yehle kancane, futhi abanye abakhiqizi eCentral Shandong babengazinzile, okusekelwe emakethe ukuze baqhubeke nokukhuphuka ngezinga elithile. I-DownTream yamandla amakhulu e-East China atholakele, okufunwa kunciphile, kanti amanye amadivaysi avaliwe ukuze alungiswe. Ukuhlinzekwa kunciphe. Isimo esithandekayo ekuhlinzekweni nasekufuneni uhlangothi sinenhlawulo ephakeme endaweni ephakeme emakethe ye-shandong, eshayela ukugxila kokuthengiselana okuphelele kwemakethe ukuze uhambe. UMeng XianXing uthe ngokululama kwamadivayisi wokunciphisa ukukhiqiza kanye nokwanda kokuhlinzekwa, intengo ye-chlorine ewuketshezi ingahle inciphile esikhathini esizayo.
Isidingo se-oxylene oxide sivilapha futhi kunzima ukuchuma ezinhlanganweni eziphakeme
I-Polytheate pollol ingumkhiqizo obaluleke kakhulu we-topylene oxide kanye nezinto eziphambili eziluhlaza zokuhlanganiswa kwe-polyurethane. Ukweqiwa okuphelele kwemboni ye-polyurethane eyedlule, ikakhulukazi ingcindezi eyeqile emakethe ye-foam ethambile, inkulu.
UMeng XianXing uthe ngoSepthemba, eqhutshwa yizindleko, i-polyther polyther mark, futhi imboni enkulu yaqhubeka nokusekela imakethe, kodwa ukusebenza okuphansi kwakwengeza isilinganiso, futhi okuphakathi nendawo okuphansi kwakusaphansi.
Njengamanje, isiponji esiphansi sikhuphuka ngokuqinile, izindleko eziphezulu zisadinga ukudluliselwa, okuphakathi nendawo okuphansi kugcina ukugaya nokulinda, futhi imakethe eqinile iyaqhubeka nokukhanya. Ngokuzayo, yize izindaba ezimbi zangempela zingakakwakhiwa, abakhiqizi abaningi basantuleka isikhala ngenxa yezindleko zokubopha izindleko, neqhaza labo ekusekeleni izinto ezikhuphukayo ze-Upstream zilinganiselwe.
Ngakolunye uhlangothi, imakethe ye-towstream ham arveam polyther imakethe yaqhubeka nomkhuba ophakeme ophakeme, futhi okuphakathi nendawo okuphansi kwaqhubeka nokuthenga ngesidingo. Yize umsebenzi ophelele wawuphansi kunasesikhathini esifanayo, kwathuthuka ngokuqhathaniswa nekota yesibili. Yize ukungena "Jinjiu", alukho ushintsho olusobala ekufunweni kwemakethe, futhi ifektri inquma ukukhiqizwa okusekelwe kwisidingo.
Esikhathini esizayo, amabhizinisi aphansi kakhulu alindelwe kakhulu - futhi ukubona, nokuzimisela kwawo ukuthenga ama-oda amasha kujwayelekile. Esimweni sokuhweba okubuthakathaka nokutshalwa kwemali, i-foal felyale "Jinjiu" ayilungile ngokwanele ukuba ijoyine amandla ku-Upstream.

Ikheminyinkampani yamakhemikhali yokuhweba eluhlaza e-China, etholakala eShanghai Pudong Indawo entsha, enethiwekhi yamachweba, ama-terminals, izikhungo zezindiza kanye namasheya amakhemikhali eShanghai, Guangzhou, Jiangginin, Dalian , ukugcina amathani angaphezu kuka-50 000 wezinto zokusetshenziswa kwamakhemikhali unyaka wonke, ngokuthola okwanele, wamukelekile ukuthenga futhi ubuze.
