I-Guangdong Petrochemical's 800,000-ton/year full-density polyethylene plant iyisitshalo sokuqala se-polyethylene esigcwele e-PetroChina esinohlelo lwemigqa emibili “yekhanda elilodwa nomsila emibili”, futhi iyisitshalo sesibili se-polyethylene esigcwele ngokugcwele esinamandla okukhiqiza amakhulu kunawo wonke. China.Idivayisi isebenzisa inqubo ye-UNIPOL kanye nenqubo yombhede we-feedized gas-phase yesigaba esisodwa.Isebenzisa i-ethylene njengempahla eluhlaza eyinhloko futhi ingakhiqiza izinhlobo eziyi-15 ze-LLDPE kanye ne-HDPE polyethylene materials.Phakathi kwazo, izinhlayiya ze-polyethylene resin ezigcwele ngokugcwele zenziwe nge-polyethylene powder exutshwe nezinhlobo ezahlukene zezithasiselo, ezishiswa ekushiseni okuphezulu ukuze zifinyelele esimweni esincibilikisiwe, futhi ngaphansi kwesenzo se-twin-screw extruder kanye nephampu yegiya elincibilikisiwe, dlula isifanekiso futhi zicutshungulwa ngaphansi kwamanzi ngomsiki.Ukwakheka kwe-granulation.Ngaphansi kwezimo ezijwayelekile zokusebenza, umugqa owodwa ungakhiqiza amathani angama-60.6 we-polyethylene pellets ngehora.
Kubikwa ukuthi inqubo yomugqa wokukhiqiza isebenzisa i-ethylene njengento eluhlaza eyinhloko kanye ne-butene-1 noma i-hexene-1 njenge-comonomer ukukhiqiza umugqa ophansi wokuminyana kanye nama-polyethylene granular resins aphakathi nendawo naphezulu.Kusukela ngesikhathi sokucindezela, umugqa wokukhiqiza usuqede ngempumelelo yonke inqubo yokucwenga-i-polymerization-degassing-recycling-extrusion granulation, izinkomba zomkhiqizo zifanelekile, futhi umthwalo wokukhiqiza ukhula kancane kancane.Ulayini wezitshalo we-Guangdong Petrochemical ongu-800,000-ton/unyaka wokuminyana ogcwele we-polyethylene uhlelelwe ukuqala ukusebenza ezinsukwini eziyi-8.
Isitshalo se-polyethylene esigcwele abantu abaningi saqala endaweni ngoSepthemba 14, 2020. Phakathi nesikhathi sokwakha, umnyango wephrojekthi encane ye-polyethylene egcwele ukuminyana unikeze umdlalo ophelele ezinzuzweni zemodeli yokuphatha edidiyelwe "yomnyango jikelele", amandla ahlangene avela wonke amaqembu, aqhubekisela phambili ngokugcwele umoya wamafutha nomoya we-Daqing, futhi athatha isinyathelo sokuhlasela ngaphandle kokulinda noma ukuthembela endaweni yephrojekthi.Izinga lokushisa eliphezulu kanye nomswakama ophezulu, imvula nesishingishane neminye imiphumela emibi.Igatsha leqembu lomnyango wephrojekthi engaphansi linikeze ukudlala okugcwele endimeni yenqaba yempi, futhi ngokulandelana lihlele uchungechunge lwemiqhudelwano yezabasebenzi njengokuthi "ukusebenza kanzima izinsuku ezingama-60", "ukugijima ikota yesine, nokuwina u-3.30"., yakha umugqa oqinile wokuvikela ukuphepha nekhwalithi, yaphelelwa "ukusheshisa" kokwakhiwa kwephrojekthi, futhi ekugcineni yaqaphela ukulethwa kwamaphakathi kwedivayisi ngoJuni 27, 2022, okwathatha izinyanga ezingu-21.5.
Esigabeni sokulungiselela ukukhiqiza, ngokuhambisana nesimo sengqondo “sokunikeza ukufakwa kodwa hhayi umthwalo wemfanelo”, nokuqhubeka nokusebenzisa umqondo othi “impumelelo yephrojekthi yomnikazi yilokho okufunwa umhlaba”, i-polyethylene sub- density egcwele Umnyango wephrojekthi uphinde wathuthukisa abaphathi, kanye nenhliziyo yokufaka - uhlelo lokuphendula Ngohlelo lwe-granulation njengomgogodla, ukuhlolwa komthwalo wamayunithi amakhulu, ukuchotshozwa kanye nokuqina komoya kwesistimu yepayipi lenqubo, ukulayishwa kwe-catalyst yokucwengisiswa kwempahla eluhlaza. , futhi ukulungiswa ngokuhlanganyela kwezinsimbi zikagesi kwenziwe ngendlela ehlelekile.Abasebenzi bokuphatha baxubene nemisebenzi yasendaweni ngokujula ukuze kuqhutshekwe kusheshiswe "uphenyo oluthathu nokunquma okune" izinto zokugcina nezinto zokuthengisa ze-PSSR.Umnyango ongaphansi kwephrojekthi ye-polyethylene egcwele ukuminyana uhlale ugcina "i-resonance ngemvamisa efanayo" nomnikazi.Ithimba lokuklama nokushayela linamathela kusayithi, ngomqondo wokuzibophezela "uhlale uqiniseka", futhi uphume konke ukubambisana ukuze kuxazululwe izingozi ezifihliwe enqubweni yokuhlola ngaphambilini, futhi uqinisekise ngokucophelela isimo sokulungiselela uhlelo lwe-catalyst , Umjovo wesistimu ye-chromocene, kanye nokuqaliswa okuqinile kwemingcele yenqubo ehlukahlukene kuye kwabeka isisekelo esiqinile sokuqalisa ngempumelelo idivayisi ngesikhathi esisodwa.
Esigabeni sokuqala sokusebenza kwezitshalo, umnyango ongaphansi kwephrojekthi ye-polyethylene egcwele ukuminyana uzophikelela ekukhonzeni ngenhliziyo yonke ukuqinisekisa ukuthi lesi sitshalo singena enkathini yokukhiqiza nokusebenza okuzinzile, siqedele ukuhlolwa kokusebenza, futhi sibambe iqhaza ekuthuthukisweni kwekhwalithi ephezulu yenkampani.
