Ekuqaleni kukaJulayi, i-styrene kanye ne-chain yayo yezimboni yaqeda ukuthambekela kwayo okucishe kube yiminyaka emithathu futhi yathuthukiswa ngokushesha futhi yavuka ngokumelene nomkhuba. Imakethe iyaqhubeka nokukhuphuka ngo-Agasti, ngezintengo ezibonakalayo ezibonakalayo ezifinyelela ezingeni lazo eliphakeme kusukela ekuqaleni kuka-Okthoba 2022 Umkhuba ophakeme wemakethe ulinganiselwe.
Izindleko ezikhuphukayo zibangela ukubuyela emuva kunzuzo ye-IComction chain inzuzo
Ukwanda okuqinile kwamanani entengo abonakalayo avuselelwayo kuholele ekudluliseleni kancane kancane kwezingcindezi zezindleko, kunciphisa ukunciphisa inzuzo ye-styrene kanye ne-towstream. Ingcindezi yokulahleka ku-Styrene nasezimbonini ze-PS inyukile, futhi ama-EPS kanye ne-ABS Industries asuse inzuzo yokulahlekelwa. Idatha yokuqapha ikhombisa ukuthi okwamanje, embonini embonini embonini, ngaphandle kwemboni ye-EPS, eguquguquka kokubili ngenhla nangaphansi kwephuzu le-breakevenen kwezinye izimboni kusephezulu. Ngokwethulwa kancane kancane kwamandla okukhiqiza amasha, okuphikisana okufunwa kokuhlinzekwa kwezimpahla ezisezimbonini ze-PS kanye ne-ABS sekuvelele. Ngo-Agasti, ukunikezwa kwe-ABS kwakwanele, futhi ingcindezi yokulahleka kwezimboni inyukile; Ukwehla kokuhlinzekwa kwe-PS kuholele ekunciphiseni okuncane ekucindezelweni kokulahlekelwa kwemboni ngo-Agasti.
Inhlanganisela yemiyalo enganele kanye nengcindezi yokulahleka iholele ekunciphiseni kwemithwalo ethile ye-Downstream
Idatha ikhombisa okuqhathaniswa nesikhathi esifanayo ngo-2022, umthwalo ojwayelekile wokusebenza we-EPS kanye nezimboni ze-PS ukhombisile ukuthambekela phansi. Ethintwa yingcindezi yokulahleka kwezimboni, umdlandla wamabhizinisi wokukhiqiza ukuze aqale ukusebenza kuye kwenza buthaka. Ukuze ugweme ingozi yokulahleka, banciphise umthwalo wabo wokusebenza owodwa ngokulandelana; Ukulungiswa okuhleliwe nokungahleliwe kugxile kakhulu kusuka ngoJuni kuya ku-Agasti. Njengoba izinkampani zesondlo ziqala ukukhiqizwa, umthwalo osebenzayo wemboni ye-styrene unyuke kancane ngo-Agasti; Ngokuya emkhakheni we-ABS, ukuphela kokulungiswa kwesizini kanye nomncintiswano womkhiqizo onolaka usuholele enkambisweni ephakeme esilinganisweni sokusebenza kwemboni ngo-Agasti.
Uma ubheka phambili: Izindleko eziphakeme esikhathini esiphakathi, amanani emakethe ngaphansi kwengcindezi, futhi inzuzo yeCommuniom Chain inomkhawulo
Esikhathini esiphakathi nendawo, uwoyela we-crude wamazwe omhlaba uyaqhubeka nokushintshanisa, futhi ukulethwa kwe-benzene emsulwa kuqinile, futhi kulindeleke ukuthi kugcinwe ukuguquguquka okuqinile. Imakethe yeStyrene yezinto zokwakha ezintathu eziluhlaza ingagcina ukuguquguquka okuphezulu. Uhlangothi oluhlinzekwayo lwezinkomba ezintathu ezinkulu lungaphansi kwengcindezi ngenxa yokwethulwa kwamaphrojekthi amasha, kepha izinga lokukhula kwesidingo lihamba kancane, okuholela ekunciphiseni inani elilinganiselwe.
Mayelana nezindleko, amanani entengo kawoyela ongahluziwe kanye ne-benzene emsulwa angathinteka ekuqinisweni kwedola laseMelika, futhi angabhekana nengcindezi yehle ngesikhathi esifushane. Kepha ngokuhamba kwesikhathi, amanani angahlala aguquguqukayo futhi aqine. Umthamo wokukhiqiza uyanda kancane kancane, futhi ukunikezwa kwe-benzene emsulwa kungaqina, ngaleyo ndlela kushayelwe amanani emakethe ukuze alondoloze ukwanda. Kodwa-ke, ukufunwa kwe-terminal enganele kungakhawulela intengo yemakethe. Esikhathini esifushane, amanani e-styrene angashintshashintsha ngamazinga aphezulu, kepha njengezinkampani zokulungisa kancane kancane aqala ukukhiqizwa, imakethe ingahle ibhekane nokulindelwe yi-Dullback.
