Kusukela ngo-Agasti, intengo yasekhaya ye-acetic acid ibilokhu ikhuphuka ngokuqhubekayo, ngentengo ephakathi yemakethe ye-2877 yuan / ton ekuqaleni kwenyanga ikhuphuka ku-3745 yuan / ithoni, inyanga ngenyanga enyuselwa ama-30.17%. Ukwanda kwamanani amasonto aqhubekayo kuphinde kwandisa inzuzo ye-acetic acid. Kulinganiselwa ukuthi inzuzo ephakathi ephakathi ye-acetic acid ngo-Agasti 21st yayingaba ngu-1070 yuan / ton. Lokhu kuphumelela enzuzo "eyinkulungwane ye-yuan" kuphinde kwaveza ukungabaza emakethe mayelana nokusimama kwamanani aphezulu.
I-DownTream yendabuko yendabuko yendabuko ngoJulayi no-Agasti yayingenamthelela omkhulu emakethe. Ngokuphambene nalokho, izici zokunikezela zidlale indima ekukhuliseleni lesi simo, ziguqula izindleko zangempela zibuswa imakethe elaliphethwe yi-acetic acid emaphethini aphethwe ngokuhlinzekwa.

Izinga lokusebenza kwezitshalo ze-acetic acid sehle, lizuze imakethe
Kusukela ngoJuni, kwahlelwa imishini yangaphakathi ye-acetic acid yesondlo, okuholela ekwehliseni inani elisebenzayo kuya okungenani kuma-67%. Umthamo wokukhiqiza wale mishini yokulungisa uyisikhulu, futhi isikhathi sokulungiswa side futhi. I-yokusungula yebhizinisi ngalinye iyaqhubeka yehla, futhi izinga lokusungula eliphelele lisezingeni eliphansi. Ekuqaleni, bekucatshangwa ukuthi imishini yesondlo izolulama kancane kancane ngoJulayi, kepha inqubekela phambili yokutakula kwemishini ejwayelekile ayikafinyeleli esimweni sokusebenza ngokugcwele, ngokuyeka, okuholela ekuvinjelweni kwezimpahla zesikhathi eside ezingase ungathengiswa ngobuningi ngoJuni futhi ngoJulayi, futhi ukusungulwa kwemakethe kuyaqhubeka ukuhlala kuphansi.

Ngokufika kuka-Agasti, imishini esezingeni eliphezulu yokulungiswa kokuqala iyalulama kancane kancane. Kodwa-ke, ukushisa okushibhile kudale ukwehluleka kwemishini ejwayelekile kwabanye abakhiqizi, futhi ukunakekelwa kanye nezimo zephutha kuye kwenzeka ngendlela egxile. Ngenxa yalezi zizathu, isilinganiso sokusebenza se-acetic acid asikafinyeleli ezingeni eliphakeme. Ngemuva kokuqongelelwa kwesondlo ezinyangeni ezimbili zokuqala, kwaba nokushoda kwezimpahla emakethe, okuholele ezimweni ezingabhekele phakathi kwamabhizinisi ahlukahlukene ngo-Agasti. Ukuhlinzekwa kwendawo yemakethe bekuqinile kakhulu, futhi amanani nawo akhuphukela ephakeme kwawo. Kulesi simo, kungabonakala ukuthi ukushoda kokuhlinzekwa kwe-Spot ngo-Agasti akubangelwa ukuqagela kwesikhashana, kodwa kunalokho okuqongelelwa isikhathi eside. Kusukela ngoJuni kuya kuJulayi, amabhizinisi ahlukahlukene alawulwa ngempumelelo uhlangothi lokuhlinzekwa ngokondlo kanye nokuxazulula inkinga, ukugcina ukusungula okuzinzile kwe-acetic acid. Kungashiwo ukuthi lokhu kuhlinzeke ngezimo ezinhle zokwanda kwamanani entengo acetic acid ngo-Agasti.

Ngo-Agasti, isilinganiso sokusebenza esisezingeni sokusebenza se-acetic acetic acesstream sasingaba ngu-58%, ukukhuphuka okungaba ngu-3.67% kuqhathaniswa noJulayi. Lokhu kukhombisa ukuthuthuka okuncane ekufunweni okwehla ekhaya. Yize izinga lokusebenza eliphakathi kwanyanga zonke alizange lidlule ama-60%, ukuqalwa kabusha kokukhiqizwa kwemikhiqizo ethile nemishini kube nomthelela omuhle emakethe yesifunda. Isibonelo, isilinganiso sokusebenza esisezingeni sokusebenza se-vinyl acetate sakhiwa ngo-18.61% ngo-Agasti. Ukuqala kabusha kwensiza kule nyanga kwakugxile kakhulu esifundeni saseNyakatho-Ntshonalanga, okuholela ekuhlinzekeni kwendawo eqinile kanye nomoya oqinile wokunyuka kwamanani esifundeni. Okwamanje, izinga lokusebenza le-PTA lisondele kuma-80%. Yize i-PTA inomthelela omncane ngentengo ye-acetic acid, isilinganiso sayo sokusebenza sibonisa ngqo inani le-acetic acid esetshenzisiwe. Njengemakethe ephansi ephansi e-East China e-East China, izinga lokusebenza le-PTA libe nomthelela omuhle emakethe ye-acetic acid.
Ukuhlaziywa Kwangemuva Kwe-Aftermarket
Ukulungiswa Kwomkhiqizi: Okwamanje, ukusungulwa kwamabhizinisi ahlukahlukene kugcinwa ezingeni eliphansi kakhulu, futhi imakethe ibhekene nokunikezwa kwendawo. Amabhizinisi azwela kakhulu izinguquko zokusungula, futhi uma yokusungula anqwayiza, kungahle kube nesinye isimo sokungasebenzi kahle kanye nokumiswa kokukhiqizwa. Ngaphambi kokusungula iqoqo, uhlangothi oluhlinzekwayo luhlala luzinzile, futhi ukulungiswa kwamasu "okuncane kungaba nomphumela omuhle kakhulu emakethe futhi. Kulindelwe ukuthi cishe ngo-Agasti 25, kuzoba nezinhlelo zokugcinwa zamadivayisi asemqoka esifundeni sase-Anhui, esinganqwabelanisa nesikhathi sokulungiswa kwesikhashana sedivayisi ye-nanjing, ngenkathi okwamanje azikho izinhlelo zokugcina njalo ezimenyezelwe kwezinye izifunda. Kulesi simo, kudingeka kakhulu ukubheka ukuguquguquka kokuguquguquka kokusungula kwebhizinisi ngalinye kanye nethuba lokuhluleka kwensiza kungazelelwe.
I-Downstream Demage: Okwamanje, Ukusungula okuphezulu kwe-acetic acetic kusasebenza, futhi amafektri aphansi agcina ukukhiqizwa okwesikhashana ngezinkontileka zesikhathi eside zesikhathi esifushane. Kodwa-ke, ukukhuphuka okusheshayo kwamanani entengo e-Upstream acece acetic kwenza kube nzima ngentengo yomkhiqizo ophansi ukuze udlulise ngokugcwele ukuqeda ukufunwa kwemakethe. Ezinye izimboni ezinkulu ezansize zibhekene nengcindezi yenzuzo. Njengamanje, phakathi kwemikhiqizo ephansi ephansi ye-acetic acid, ngaphandle kwe-methyl acetate kanye ne-n-propll ester, inzuzo yeminye imikhiqizo cishe ku-par ngomugqa wezindleko. Inzuzo ye-vinyl acetate (ekhiqizwa yi-calcium carbide indlela), i-PTA, kanye ne-butyl acetate aze abonise into engenele. Ngakho-ke, amabhizinisi ambalwa athathe izinyathelo zokunciphisa umthwalo wazo noma ayeke ukukhiqizwa.

Izimboni ezansize zibuke futhi ukubona ukuthi amanani entengo angabonakala yini inzuzo yokugcina. Uma inzuzo yemikhiqizo ephansi yehle ngenkathi intengo ye-acetic acid ihlala iphakeme, kulindeleke ukuthi ukukhiqizwa kwehlathi kuyaqhubeka ukwehla ukuze ulinganise isimo senzuzo.

Umthamo omusha Wokukhiqiza: Kulindelwe ukuthi ngasekupheleni kukaSepthemba nango-Okthoba, kuzoba nenani elikhulu lamayunithi amasha okukhiqiza nge-Vinyl Acetate, afinyelela kumathani acishe abe ngu-390000 wamathani angama-270000 we acetic acid. Ngasikhathi sinye, kulindeleke ukuthi umthamo omusha wokukhiqiza we-capactacm uyofinyelela amathani angama-300000, azodla amathani acishe abe ngu-240000 we-acetic acid. Okwamanje kuqondakala ukuthi imishini engezansi ephansi okulindeleke ukuthi isetshenziswe ingaqala ukukhiqizwa kwangaphandle kwe-acetic acid maphakathi noSepthemba. Njengoba kunikezwe ukuhanjiswa kwamanje okuqinile emakethe ye-acetic acid, ukukhiqizwa kwale mishini emisha kuzohlinzekwa ukusekelwa okuhle kwemakethe ye-acetic acid futhi.

Esikhathini esifushane, intengo ye-acetic acid isagcina umkhuba wokuguquguquka okuphezulu, kepha ukwanda ngokweqile kwezindleko ze-acetic acid isonto eledlule kudale ukwehla kwabakhiqizi obuphansi, okuholela ekunciphiseni kancane kancane komthwalo kanye nokwehla komdlandla. Njengamanje, kukhona ezinye "foam" ezigcwele emakethe ye-acetic acid, ngakho-ke intengo ingawela kancane. Mayelana nesimo semakethe ngoSepthemba, kusadingekile ukuqapha eduze isikhathi sokukhiqizwa sekhono elisha lokukhiqiza acid. Njengamanje, ukusungulwa kwe-acetic acid kuphansi futhi kungagcinwa kuze kube ekuqaleni kukaSepthemba. Uma umthamo omusha wokukhiqiza ungafakwanga ukuze uhlelelwe ngaphambi kokuphela koSepthemba, amandla aphansi okukhiqiza angathengwa nge-acetic acid ngaphambi kwesikhathi. Ngakho-ke, sihlala sinelisekile mayelana nomkhuba wemakethe ngoSepthemba futhi sidinga ukubheka izitayela ezithile zezimakethe ezikhuphukayo neziphansi, ukubhekisisa izinguquko ze-real-time emakethe.
