[Umhlahlandlela]: Ngasekupheleni kukaJuni, ukuvalwa okungalindelekile kwemishini yemakethe ye-propylene kwenzeka ngokulandelana, okwakuhle ohlangothini lokuhlinzeka, kuyilapho umdlandla wemikhiqizo engezansi ukhuphuka, futhi intengo yemakethe yayeka ukwehla, kusukela ngoJulayi 14, ukuthengiselana okujwayelekile kwentengo yemakethe ye-propylene yeShandong kwakungu-6480-6500 yuan/ton, kanti ukuthengiselana okujwayelekile kwemakethe yase-East China kwakungu-6350-6350 yuan/ton.

Kulo mjikelezo, imakethe ye-propylene yasekhaya iyeke ukwehla futhi yalulama, futhi izici ezisekela ukubuyela emuva kwemakethe zigxile kakhulu ezisekelweni zokuhlinzekwa kanye nesidingo. Amanani kawoyela aphesheya kwezilwandle akhuphukile, izici ezinhle eziyinhloko yilezi: idatha yokwehla kwamandla emali yase-United States ilungile, i-Federal Reserve iyaqhubeka nokuphakamisa ingcindezi yamazinga enzalo ibuthakathaka, kanye nokunciphisa okwengeziwe kokukhiqiza kwe-Saudi Arabia kwaletha ukuqhubeka kwesimo esihle, emakethe. Ngesikhathi esifanayo, ukupaka okwesikhashana kwamadivayisi e-propylene e-Qingdao Jinneng, e-Wangtong, nase-Zhenghe esifundeni, kuyilapho idivayisi yokulungisa yokupaka yasekuqaleni ingakaqalwa kabusha, futhi ukunikezwa kubhekene nemakethe ngokusekelwa okuthile, kanti izinga lokukhiqiza le-PDH likazwelonke lingu-69.79% ezinsukwini ezingu-14, okungaphansi ngo-0.2% kunomjikelezo odlule. Ngokuwa kokwakhiwa kwe-propylene, uhlu lwamabhizinisi okukhiqiza i-propylene aluphezulu lulonke, intengo yokunikezwa iphakanyiswa kancane kancane, intshiseko yokuthenga engezansi ingcono, futhi isimo sokuhweba sisonke silungile.

Kulo mjikelezo, izinqubo ezintathu ze-propylene zixubile, futhi inzuzo yokuncishiswa kwe-propane ibe yi-propylene isobala kakhulu. Ngakolunye uhlangothi, intengo ye-propane iyaqhubeka nokuwa kulesi sigaba, kanti ngakolunye uhlangothi, intengo ye-propylene monomer inamandla, okunikeza ukukhushulwa okuthile emkhubeni wenzuzo. Inzuzo ye-naphtha kanye ne-methanol ku-propylene yaqhubeka nokwehla, kanti inzuzo yenqubo ye-methanol ku-propylene yehle kakhulu, okwathintwa kakhulu yintengo ekhuphukayo yezinto zokusetshenziswa ze-methanol, okwaphazamisa inzuzo. Inzuzo yenqubo ye-naphtha ku-propylene ivame ukwehla kusukela ngesonto eledlule, into eyinhloko ethonyayo intengo ye-naphtha iyancipha iye phezulu, kodwa futhi ekudonseleni kwenzuzo okubangelwa, kulindeleke ukuthi ithrendi yenzuzo ye-propylene yesikhashana iguquke, sekwephuzile qaphela intengo yemakethe yezinto zokusetshenziswa.

Esikhathini esifushane, ohlangothini lokunikezwa, ngokuqaliswa kabusha kwamadivayisi e-PDH eShandong, umthwalo wamadivayisi asanda kufakwa ekukhiqizweni esigabeni sokuqala uyanda kancane kancane, futhi ukunikezwa kwamanje kwe-propylene kulindeleke ukuthi kwande, kodwa ukupaka okwesikhashana kwamadivayisi efektri ngayinye eShandong kuzonikeza imakethe amandla athile. Ohlangothini lwesidingo, kulesi sigaba, imakethe ye-polypropylene ivame ukuba nomkhuba oqinile, inzuzo yempuphu ilungile, amafektri aphansi adinga nje ukuthenga ikakhulukazi, kuyilapho ngesonto elizayo i-PO, ifektri ye-acrylonitrile kulindeleke ukuthi iqale kabusha, kulindeleke ukuthi imakethe ye-propylene yesikhathi esifushane ingase ibe nokukhula okuncane, kodwa isikhala sokukhuphuka sinqunyelwe, landela eduze ukuqala kabusha nokuthunyelwa kwabakhiqizi be-propylene.

Uhlangothi lwesidingo, ukuthambekela kwemakethe ye-polypropylene kulo mjikelezo, ukwesekwa kohlangothi lwesidingo kunamandla, intengo ye-pre-stack propylene yehle yaya phansi, ukusabalala phakathi kwe-propylene ne-PP kwanda, inzuzo yefektri engezansi yanda kancane kancane, intshiseko yokuthenga nayo yanda kancane kancane, kwaholela ekuthunyelweni okubushelelezi kwamabhizinisi e-propylene, isikhundla sempahla kancane kancane saya phansi, ukusekela amanani e-propylene kwanda.
