[Isikhokelo] : Ekupheleni kukaJuni, ukuvalwa okungalindelekanga kwezixhobo zentengiso yepropylene kwenzeka enye emva kwenye, eyayithandeka kwicala lokubonelela, ngelixa intshiseko yeemveliso ezisezantsi zathatha, kwaye ixabiso lentengiso layeka ukuwa, ukusukela nge-14 kaJulayi, eyona nto iphambili. transaction of Shandong propylene market price was 6480-6500 yuan/ton, kunye intengiselwano engundoqo ye-East China market yaba 6350-6350 yuan/ton.

Kulo mjikelo, imakethi yepropylene yasekhaya iyekile ukuwa kwaye yaphinda yachacha, kwaye izinto ezixhasa ukubuya kwemarike ikakhulu kwiziseko zobonelelo kunye nemfuno. I-Macro, amaxabiso e-oyile kumazwe ngamazwe anyukile, izinto eziphambili ezilungileyo zezi: idatha yokunyuka kwamaxabiso e-United States ilungile, i-Federal Reserve ukuqhubeka nokunyusa izinga lenzala yoxinzelelo olubuthathaka, kunye nokunciphisa imveliso eyongezelelweyo ye-Saudi Arabia kuzisa ukuqhubeka kwemoya elungileyo, imarike. Ngelo xesha, ukupaka okwethutyana kwe-Qingdao Jinneng, i-Wangtong, kunye ne-Zhenghe izixhobo zepropylene kummandla, ngelixa isixhobo sokugcina indawo yokupaka ekuqaleni asizange siqalise kwakhona, kwaye unikezelo lujongene nemarike ngenkxaso ethile, kunye nezinga lemveliso ye-PDH yesizwe. yi-69.79% njengeentsuku ezili-14, engaphantsi kwe-0.2% kunomjikelo wangaphambili. Ngokuwa kolwakhiwo lwepropylene, uluhlu lwamashishini emveliso yepropylene aluphezulu xa lulonke, ixabiso lonikezelo linyuswa ngokuthe ngcembe, umdla wokuthenga osezantsi ungcono, kwaye umoya wokurhweba ngokubanzi ulungile.

Kulo mjikelo, iinkqubo ezintathu zepropylene zixutywe, kwaye inzuzo yepropane dehydrogenation kwipropylene ibonakala ngakumbi. Ngakolunye uhlangothi, ixabiso lendawo yepropane liyaqhubeka liwela kweli nqanaba, kwaye ngakolunye uhlangothi, ixabiso le-propylene monomer linamandla, elinika ukunyusa okuthile kwindlela yokwenza inzuzo. Inzuzo ye-naphtha kunye ne-methanol kwipropylene yaqhubeka iyancipha, kwaye inzuzo ye-methanol kwinkqubo yepropylene yehla kakhulu, eyayichatshazelwa kakhulu kukunyuka kwexabiso le-methanol eluhlaza, eyayithintela inzuzo. INaphtha ukuya kwipropylene inkqubo yenzuzo ithande ukuhla ukusuka kwiveki ephelileyo, eyona nto inefuthe elikhulu lixabiso le-naphtha elimxinwa ukuya phezulu, kodwa nakwinzuzo yokutsala inzuzo ebangelwayo, kulindeleke ukuba ibe lixesha elifutshane lokuguquguquka kwengeniso yepropylene, nikela ingqalelo kade kwimarike. ixabiso lezinto ekrwada.

Ngexesha elifutshane, kwicala lokubonelela, kunye nokuqaliswa kwakhona kwezixhobo zePDH eShandong, umthwalo wezinto ezisanda kufakwa kwimveliso kwinqanaba lokuqala uye wanda ngokuthe ngcembe, kwaye unikezelo lwangoku lwepropylene kulindeleke ukuba lwande, kodwa ukupaka okwethutyana. izixhobo zomzi-mveliso ngamnye eShandong ziya kunika ukomelela okuthile kwimarike. Icala lemfuno, ngeli nqanaba, imarike ye-polypropylene ithande ukuba yinto eqinile, inzuzo yomgubo ilungile, iifektri ezisezantsi zifuna nje ukuthenga ngokukodwa, ngelixa ngeveki ezayo i-PO, i-acrylonitrile factory kulindeleke ukuba iqalise kwakhona, kulindeleke ukuba ipropylene yexesha elifutshane. imarike inokuba nokunyuka okuncinci, kodwa indawo yokunyuka ilinganiselwe, landela ngokusondeleyo ekuqaliseni kwakhona kunye nokuthunyelwa kwabavelisi bepropylene.

Icala lemfuno, imeko yemarike yepolypropylene kumjikelo, inkxaso yecala lemfuno yomelele, ixabiso lepropylene langaphambili lehle laya phantsi, ukusasazeka phakathi kwepropylene kunye nePP kwandisiwe, inzuzo yefektri esezantsi yonyuka ngokuthe ngcembe, umdla wokuthenga nawo wachongwa ngokuthe ngcembe. phezulu, kukhokelele ekuhanjisweni okugudileyo kwamashishini epropylene, indawo ye-inventri ngokuthe ngcembe ukuya ezantsi, amaxabiso epropylene enkxaso phezulu.
