[Umhlahlandlela] : Ekupheleni kukaJuni, ukuvalwa okungalindelekile kwemishini yemakethe ye-propylene kwenzeka ngokulandelana, okwakuvuna uhlangothi lokuhlinzeka, ngenkathi umdlandla wemikhiqizo ephansi kakhulu ukhuphuka, futhi intengo yemakethe yayeka ukwehla, kusukela ngomhla ka-14 Julayi, i-mainstream. ukuthengwa kwentengo yemakethe ye-Shandong propylene bekungu-6480-6500 yuan/ton, futhi umsebenzi ovamile wemakethe yase-East China wawungu-6350-6350 yuan/ton.

Kulo mjikelezo, imakethe ye-propylene yasekhaya iyekile ukuwa futhi yasimama, futhi izici ezisekela ukubuya kwemakethe zigxile kakhulu ezintweni eziyisisekelo zokuhlinzekwa nokufunwa. I-Macro, amanani entengo kawoyela wamazwe ngamazwe akhuphuka, izici ezinhle eziyinhloko yilezi: idatha ye-inflation yase-United States inhle, i-Federal Reserve ukuqhubeka nokunyusa izinga lenzalo ingcindezi iyancipha, futhi ukwehla kokukhiqiza okwengeziwe kweSaudi Arabia kubangele ukuqhubeka komkhathi omuhle, imakethe. Ngaso leso sikhathi, indawo yokupaka yesikhashana ye-Qingdao Jinneng, i-Wangtong, ne-Zhenghe propylene device esifundeni, kuyilapho idivayisi yokulungiswa kwendawo yokupaka ingakaqalwa kabusha, futhi ukunikezwa kubheke emakethe ngokusekelwa okuthile, kanye nezinga lokukhiqiza le-PDH likazwelonke. ingama-69.79% kusukela ezinsukwini eziyi-14, okungaphansi ngo-0.2% kunomjikelezo odlule. Ngokuwa kokwakhiwa kwe-propylene, i-inventory yamabhizinisi okukhiqiza i-propylene ayiphezulu ngokuphelele, intengo yokunikezwayo iyakhuphuka kancane kancane, umdlandla wokuthenga ongezansi ungcono, futhi isimo sokuhweba jikelele silungile.

Kulo mjikelezo, izinqubo ezintathu ze-propylene zixutshwe, futhi inzuzo ye-propane dehydrogenation ku-propylene ibonakala ngokucacile. Ngakolunye uhlangothi, intengo yendawo ye-propane iyaqhubeka nokuwa kulesi sigaba, futhi ngakolunye uhlangothi, intengo ye-propylene monomer inamandla, okunikeza ukukhushulwa okuthile kumkhuba wenzuzo. Inzuzo ye-naphtha ne-methanol ku-propylene yaqhubeka yehla, futhi inzuzo ye-methanol kuya ku-propylene inqubo yehla kakhulu, eyayithinteke kakhulu ngenxa yokukhuphuka kwentengo ye-methanol eluhlaza, evimbe inzuzo. Inzuzo yenqubo ye-Naphtha iye ku-propylene ivame ukwehla kusukela ngesonto eledlule, isici esinomthelela omkhulu yintengo ye-naphtha ewumngcingo ukuya phezulu, kodwa futhi ekudonseni inzuzo yokushayela okubangelwayo, kulindeleke ukuthi kube mkhuba wesikhathi esifushane wokuguquguquka kwenzuzo ye-propylene, sekwephuzile ukunaka kakhulu imakethe. intengo yezinto zokusetshenziswa.

Esikhathini esifushane, ohlangothini lokuhlinzeka, ngokuqalwa kabusha kwamadivayisi we-PDH e-Shandong, umthwalo wezinto ezisanda kufakwa ekukhiqizeni ekuqaleni kwesigaba sokuqala ukhuphuka kancane kancane, futhi ukunikezwa kwamanje kwe-propylene kulindeleke ukuthi kwande, kodwa ukupaka okwesikhashana amadivaysi emboni ngayinye eShandong azonikeza amandla athile emakethe. Uhlangothi lwesidingo, kulesi sigaba, imakethe ye-polypropylene ijwayele umkhuba oqinile, inzuzo ye-powder ilungile, amafektri aphansi adinga ukuthenga ikakhulukazi, kanti ngesonto elizayo i-PO, i-acrylonitrile factory kulindeleke ukuthi iqale kabusha, kulindeleke ukuthi i-propylene yesikhashana esifushane. imakethe ingase ibe nokukhuphuka okuncane, kodwa isikhala sokukhuphuka silinganiselwe, landela eduze ukuqaliswa kabusha nokuthunyelwa kwabakhiqizi be-propylene.

Uhlangothi lwesidingo, inkambiso yemakethe ye-polypropylene emjikelezweni, ukusekelwa kohlangothi lwesidingo kunamandla, intengo ye-propylene yangaphambi kwesitaki yehle yaba phansi, ukusabalala phakathi kwe-propylene ne-PP kwakhula, inzuzo yefekthri engezansi yanda kancane kancane, umdlandla wokuthenga nawo wakhula kancane kancane. phezulu, kwaholela ekuthunyelweni okubushelelezi kwamabhizinisi e-propylene, indawo yokusungula kancane kancane yaya phansi, amanani e-propylene akhuphuka.
