Ukuhola: Kusukela ngoSepthemba, imakethe yasekhaya ye-propylene oxide iyonke ikhombise ukukhuphuka okuzinzile, ekuqaleni kwenyanga, wonke amaqembu emakethe anethemba ngesizini ephezulu “yegolide eyisishiyagalolunye”, imakethe iqhubekile nokukhuphuka futhi. ikhuphuke, kodwa ikhuphuke yafinyelela ku-9550-9670 yuan/ton (imboni yokushintshanisa indawo yaseShandong), imakethe isiphenduke yaba nzima, ngezinga elithile, yashaya ukuzethemba kwemboni, ngempelasonto edlule ngemuva kokwehla okufanele kwe-cyC, ngezindleko ze ukudonsa okusobala, Imakethe yasheshe yayeka ukuwa futhi yangenisa omunye umjikelezo wemakethe ekhuphukayo, kusukela ngo-September 15, kuya ku-9650-9750 yuan/ton, yafinyelela endaweni ephakeme engxenyeni yesibili yonyaka, futhi ukukhula kukonke kwehla.

Okokuqala, izinga lokusebenzisa amandla ohlangothini lokunikezela libonise inkambiso yokululama

Maphakathi noSepthemba wasekuqaleni, izinga lokusebenzisa amandla emakethe yasekhaya ye-propylene oxide belilokhu ligcinwa lisezingeni eliphansi cishe lika-60% -65%, futhi imishini eminingi efana neJincheng Petrochemical, Taixing Yida, Wanhua Phase I, Tianjin Bohua esimweni sokupaka, okuhambisana nokugcinwa kwesikhashana kanye nokwehliswa kwemishini emikhulu efana ne-Xinyue ne-Jiahong, njll., ukunikezwa kwemakethe kulinganiselwe, futhi intengo nayo idlale ukwesekwa okuthile.

Ngesonto eledlule, i-Xinyue kanye ne-Jiahong ngokulandelana baphakamisa ukusebenza okungalungile, okuhlanganiswe nokuqalwa kabusha kwedivayisi ye-Wanhua Isigaba I, kuya ku-September 15, izinga lokusebenzisa amandla embonini lenyuke laya ku-71.50%, okuwukunyuka ngamaphesenti angu-5.79 uma kuqhathaniswa nokuqala kwenyanga, ukukhula kokukhiqizwa kwansuku zonke kwamathani ayizigidi ezingu-0.1, kuyilapho i-East China ine-US dollar kanye ne-Zhejiang petrochemical ship cargo offer to the port, indawo yasendaweni inesengezo esithile.

Ekulandeleni, alukho uhlelo lokuguquguquka kwamadivayisi amaningi asendaweni, futhi i-Jincheng Petrochemical yaqala ukuthengisa i-hydrogen peroxide, kodwa idivayisi yayo ye-HPPO engu-300,000 / ngonyaka ayikalindeleki ngokusobala ukuthi iqale kabusha, qhubeka nokunaka ukunikezwa okuphelele. kulindeleke ukuthi izinze ngaphambi kweholidi.

Okwesibili, izinto zokusetshenziswa ziphezulu zaqhubeka nokukhuphuka kakhulu

Ngokombono wezindleko, ngesonto eledlule, izinto zokusetshenziswa eziyinhloko ze-propylene kanye ne-chlorine ewuketshezi endleleni ye-chlorohydrin ziye zanda kakhulu, ezifinyelele izinga eliphakeme kakhulu ngonyaka, nakuba intengo ye-cyclopropylene nayo ikhuphuke ngezinga elithile, kodwa izinga lokukhula alisheshi njengezindleko, futhi idigri yokulahlekelwa iyanwetshwa ngokuqhathaniswa nasekuqaleni kwenyanga, kulo mzuliswano wokukhuphuka kwemakethe, umphumela omuhle entengo unamandla, kanye nenqubo ye-HPPO, ngoba intengo wezinto ezivamile zokusetshenziswa propylene unyukile. I-hydrogen peroxide ibalwa ngokuvumelana nezindleko zedivayisi ye-theoretical, futhi umehluko wezindleko phakathi kwezinqubo ezimbili uyancishiswa, kodwa intengo ye-hydrogen peroxide iyaqhubeka nokukhuphuka kakhulu, futhi kuyadingeka ukunaka ukuthi ingabe ithinta izinqubo ezithile ze-HPPO ukulungisa umthwalo. yedivayisi yabo ye-cyclopropyl futhi bathengise i-hydrogen peroxide phesheya.

Kuleli sonto, i-propylene ne-liquid chlorine kulindeleke ukuthi zihlanganiswe ezingeni eliphezulu, futhi kulindeleke ukuthi ngaphansi kwemakethe yokugcwalisa ingxenye yangaphambi kweholide, kusekhona ukusekelwa okuthile kwemakethe ye-cycloC.

Okwesithathu, uhlangothi lwesidingo lwenani eliphakeme elilinganiselwe lokulinda nokubona lucophelele

Mayelana nesidingo esingaphansi komfula, ukusebenza kwe-polyether kuqeda ama-oda amasha enkathini ephakeme ye-"gold nine" kusagculisa kodwa akufiki kulokho okulindelekile, uma kuqhathaniswa nemakethe ngoJulayi-Agasti, akukho ukuthuthukiswa okuphawulekayo, ngemva kokubuka i-CIC iphuma phansi. ngesonto eledlule, ukukhuphuka okukodwa okuphansi komfula kunqunyelwe ukuqhubeka, ikakhulukazi ngokusekelwe ekulethweni kwama-oda angaphambi kwesikhathi, futhi ngemva kokubuka amanani aphezulu e-CIC, isigqi sokuthenga ngokuvamile siyehliswa. Imboni ye-propylene glycol ngokuvamile yenza inzuzo, futhi idivayisi ishintshashintsha kakhulu, futhi umthelela unomkhawulo.

Ekulandeleni, kusekhona amasonto amabili kusukela eholidini le-11, kulo mzuliswano wemakethe ekhuphukayo, amanye amakhasimende agcinwe ngokusesilinganisweni, futhi kunesidingo esincane kuleli sonto, futhi ukuphela kwenyanga kuyasondela. isikhathi samaholide, futhi imakethe kulindeleke ukuthi ibe seholidini ngokulandelana.

Okwesine, ukukhuphuka kungase kwehle ngaphambi komkhosi wokuzinzisa noma ububanzi obuncane

Isiphetho (isikhathi esifushane) : Ngesonto eledlule, intengo yemakethe ekhuphukayo ikhuphukele endaweni ephakeme entsha engxenyeni yesibili yonyaka, futhi maduzane, ukusimama kulindeleke ukuthi kubuyele ekuzinzeni, kuleli sonto, kusekhona inani elincane lesitoko. isidingo sokuphela kwe-polyether, i-CIC kulindeleke ukuthi ibe nokuma, ngasekupheleni kwenyanga, amaqembu asekela ubuthakathaka, noma kukhona ukwehla okuncane kokulindelwe.

Isiphetho (isikhathi esimaphakathi neside) : Ngo-Okthoba, kufanele sinake ukushintshashintsha kwemishini ehlukahlukene phakathi neholide, i-Tianjin Bohua kulindeleke ukuthi iqale kabusha ngemva kweholide, u-Shandong Jinling angase abe nokulindela ukulungiswa, abuyele ebangeni elincane ngemva kwesitoko. kuyalungiswa, futhi ukugcinwa kweShell engxenyeni yesibili yonyaka, kunake intuthuko ethile.

Isexwayiso sobungozi: ukungaqiniseki kwenodi yesikhathi ekhuphukayo yendawo yedivayisi; Uma ingcindezi yezindleko ngemuva kwentshiseko yebhizinisi ukuqala; Uhlangothi lwesidingo sokufika kokusetshenziswa kwangempela.
