Iimakethe ye-propylene oxideI-"Jinjiu" yaqhubeka nokukhuphuka kwayo kwangaphambilini, futhi imakethe yephula i-yuan engu-10000 (intengo yethani, efanayo ngezansi) umkhawulo.Uma sithatha imakethe yaseShandong njengesibonelo, intengo yemakethe ikhuphuke yafinyelela ku-10500~10600 yuan ngoSepthemba 15, yakhuphuka cishe ngamayuan ayi-1000 kusukela ekupheleni kuka-Agasti.Ngomhla zingama-20 kuMandulo, yehle yaba cishe ngama-yuan angama-9800.Ngokuzayo, uhlangothi lokuhlinzeka kulindeleke ukuthi lukhule, inkathi yokuphakama kwesidingo ayinamandla, futhi i-propylene oxide ishintshashintsha ngo-10000 yuan.
Ukwenyuka kokunikezwa kokuqala kabusha kweyunithi ye-propylene oxide
Ngo-Agasti, ingqikithi yamasethi angu-8 we-propylene oxide units yalungiswa e-China, ehlanganisa umthamo ophelele wamathani angu-1222000 ngonyaka kanye nokulahlekelwa okuphelele kwamathani angu-61500.Ngo-Agasti, ukukhiqizwa kwesitshalo sasekhaya se-propylene oxide kwaba amathani angu-293200, phansi ngo-2.17% ngenyanga, futhi izinga lokusebenzisa amandla lalingu-70.83%.
NgoSepthemba, iyunithi ye-Sinochem Quanzhou propylene oxide yavalwa ukuze ilungiswe, i-Tianjin Bohai Chemical, i-Changling, i-Shandong Huatai namanye amayunithi aqalwa kabusha ngokulandelana, futhi iyunithi ye-Jinling yehliswa yaba uhhafu womsebenzi wokulayisha.Njengamanje, izinga lokusebenza le-propylene oxide lisondele ku-70%, liphansi kancane kunalokho ngo-Agasti.
Ngokuzayo, iyunithi ye-100000 t/a ye-Shandong Daze izophinda iqalise ukukhiqiza ngasekupheleni kukaSepthemba, kanti iyunithi ye-Jincheng Petrochemical's 300000 t/a kulindeleke ukuthi ifakwe ekukhiqizeni ekupheleni kukaSepthemba;Izitshalo ze-Jinling ne-Huatai zibuyela ekukhiqizeni isinyathelo ngesinyathelo.Uhlangothi lokunikezela luyanda kakhulu, futhi abahwebi bane-bearish eyengeziwe.Kulindeleke ukuthi imakethe ye-propylene oxide izokhombisa ukuthambekela okubuthakathaka kokusimama ngaphansi kokwanda kokugxila kokunikezwayo, ngengozi encane yokwehla.
Ukusekelwa kwe-propylene oxide impahla eluhlaza kulindeleke ukuthi kube nzima
Ukuze uthole izinto zokusetshenziswa ezikhuphukayo ze-propylene ne-liquid chlorine, nakuba i-"Jinjiu" ingenise igagasi lemakethe ekhulayo, kulindeleke ukuthi kube lula ukuwa kunokukhuphuka emakethe yesikhathi esizayo, okuzoba nzima ukwakha ukudonsa okuqinile umfula ongezansi.
NgoSeptemba, intengo ye-propylene, impahla eluhlaza ekhuphuka phezulu, yaqhubeka ikhuphuka ngokushaqeka, okwanikeza nokusekelwa okuqinile kwemakethe ye-propylene oxide.U-Wang Quanping, unjiniyela omkhulu we-Shandong Kenli Petrochemical Group, uthe ukunikezwa kwe-propylene yasekhaya kuhlala kuqinile, nokusebenza okusobala enyakatho-ntshonalanga, maphakathi nasempumalanga yeChina.Ngaphezu kwalokho, ezinye izinto zokulungisa ezansi nomfula we-propylene, njenge-Tianjian Butyl Octanol, i-Dagu Epoxy Propane, ne-Kroll Acrylonitrile, ziqalise kabusha ukwakhiwa.Ngakho-ke, isidingo semakethe sikhuphukele phezulu, amabhizinisi e-propylene abethengisa ngokushelela, futhi ukusungula okuphansi kuye kwanyusa amanani e-propylene.
Ngokombono wokusebenza kweyunithi, ngakolunye uhlangothi, amayunithi e-Xintai Petrochemical kanye ne-propylene aqalwe kabusha, kodwa umthelela wawunomkhawulo uma kuqhathaniswa ngenxa yokubambezeleka okuvamile.Ngesikhathi esifanayo, amandla amasha okukhiqiza we-propane dehydrogenation ku-propylene e-Shandong afakwa ekusebenzeni ngaphansi kwalokho obekulindelwe, futhi ukunikezwa okuphelele kwakulawuleka ngokuqhathaniswa.Ngakolunye uhlangothi, esikhathini esizayo esiseduze, amanye amayunithi amakhulu enyakatho-ntshonalanga avaliwe ukuze alungiswe, futhi ukuqaliswa kwe-propylene enyakatho-ntshonalanga kwehle ku-73.42%.Ukujikeleza kwezimpahla ze-peripheral propylene kwehle kakhulu.Ngaphezu kwalokho, ezinye izitshalo ezisenyakatho-ntshonalanga zigcine isidingo se-propylene sokukhiqizwa kwangaphandle, futhi ukuhlinzekwa kwe-peripheral propylene kuye kwaqiniswa kakhulu.
Esikhathini esizayo, umthwalo weyunithi wamabhizinisi we-propylene uzinzile, futhi akukho okulindelekile kwezinguquko ezibalulekile ekuhlinzekeni kwe-propylene.Izifunda eziseduze kwaseShandong naseMpumalanga China zisazogcina ukutholakala okuqinile.I-downstream ijwayele ukuba buthaka ngepuleti, icindezele umdlandla wokuthenga we-propylene ezansi nomfula.Ngakho-ke, imakethe yamanje ye-propylene isesimweni sokunikezwa okubuthakathaka kanye nesidingo, kodwa i-octanol engezansi, i-propylene oxide, i-acrylonitrile nezinye izimboni ziye zandisa umthwalo wazo, futhi uhlangothi oluqinile lwesidingo lusenokusekelwa okuthile.Kulindeleke ukuthi intengo elandelayo ye-propylene izoguquguquka ebangeni elincane, ngokukhuphuka nokuwa okulinganiselwe.
Enye impahla eluhlaza, i-liquid chlorine, ingumdlali omkhulu emakethe.Ivolumu yokuthengisa yangaphandle yokugcinwa kwemishini yezimboni ezinkulu yehle kancane, futhi abanye abakhiqizi enkabeni yeShandong babengazinzile, ababesekela imakethe ukuthi iqhubeke nokukhuphuka ngezinga elithile.Amandla aphansi e-East China aseluleme, isidingo sesidambile, futhi ezinye izisetshenziswa zivaliwe ukuze zilungiswe.Ukunikezwa kunciphile.Isimo esivumayo ngasohlangothini lokuhlinzeka nesidingo senyuke kakhulu emakethe yaseShandong, okuqhubekisela phambili ukugxila kokusebenza kwemakethe ukuthi kukhuphuke.UMeng Xianxing uthe ngokutholwa kabusha kwemishini yokunciphisa ukukhiqiza kanye nokwenyuka kokuhlinzekwa, intengo ye-chlorine ewuketshezi ingase yehle esikhathini esizayo.
Isidingo se-propylene oxide siyavilapha futhi kunzima ukuchuma ngezinkathi zonyaka eziphakeme kakhulu
I-polyether polyol iwumkhiqizo obaluleke kakhulu ongezansi womfula we-propylene oxide kanye nempahla eluhlaza eyinhloko ye-polyurethane synthesis.Umthamo omkhulu wemboni yasekhaya ye-polyurethane ezansi nomfula, ikakhulukazi ingcindezi eyeqile yemakethe yegwebu elithambile, inkulu.
UMeng Xianxing uthe ngoSepthemba, eqhutshwa yizindleko, imakethe ye-polyether ethambile ye-foam yaphakama, futhi imboni eyinhloko yaqhubeka nokusekela imakethe, kodwa ukusebenza komfula kwakuphakathi, futhi ukufinyelela okuphakathi naphansi kwakusephansi.
Njengamanje, isipontshi esisezansi nomfula sikhula kancane kancane, izindleko ezikhuphuka nomfula zisadinga ukudluliselwa, indawo ephakathi nendawo nephansi igcina ukugaya nokulinda, futhi imakethe eqinile iyaqhubeka nokuba lula.Esikhathini esizayo, nakuba izindaba ezimbi zangempela zingakakheki, abakhiqizi abaningi basantula indawo ngenxa yokuncishiswa kwezindleko, futhi indima yabo ekusekeleni izinto zokusetshenziswa ezikhuphukayo zilinganiselwe.
Ngakolunye uhlangothi, imakethe ye-polyether ye-foam eqinile ezansi nomfula igcine ukuthambekela okuphansi phezulu, futhi okuphakathi nendawo naphansi kwaqhubeka nokuthenga ngokufunwa.Nakuba umsebenzi usuwonke ubuphansi kunesikhathi esifanayo, ube ngcono uma uqhathaniswa nekota yesibili.Nakuba kungena "iJinjiu", alukho ushintsho olusobala ekufuneni kwemakethe, futhi imboni inquma ukukhiqiza ngokusekelwe ekudingeni.
Ngokuzayo, amabhizinisi aphansi kakhulu alinda futhi abone, futhi ukuzimisela kwawo ukuthenga ama-oda amasha kujwayelekile.Esimweni sokuhweba okubuthakathaka kanye nokutshalwa kwezimali, i-polyether yegwebu eliqinile "Jinjiu" ayilungile ngokwanele ukufaka amandla phezulu.
