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 amakhulu okukhiqiza e-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 nepompo yegiya elincibilikisiwe, zidlula isifanekiso futhi zicutshungulwe ngaphansi kwamanzi ngumsiki. 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 ngokugcwele saqala endaweni ngo-September 14, 2020. Ngesikhathi sokwakha, umnyango wephrojekthi encane ye-polyethylene egcwele ukuminyana unikeze ukudlala okugcwele ngezinzuzo zemodeli yokuphatha edidiyelwe "yomnyango jikelele", amabutho ahlangene avela kuzo zonke izinhlangothi, aqhubekisela phambili ngokugcwele umoya kawoyela nomoya we-Daqing, futhi uthathe isinyathelo ngaphandle kokulinda noma indawo ukuhlasela ngaphandle kokulinda. Izinga lokushisa eliphezulu kanye nomswakama ophezulu, imvula nesishingishane neminye imiphumela emibi. Igatsha leqembu lomnyango wephrojekthi engaphansi linikeze umdlalo ogcwele 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, ngo-2 Juni 2016 2022, eyathatha izinyanga ezingama-21.5.
Esigabeni sokulungiselela ukukhiqiza, ngokuhambisana nesimo sengqondo “sokunikeza ukufakwa kodwa hhayi umthwalo wemfanelo”, nokuqhubeka nokusebenzisa umqondo wokuthi “impumelelo yephrojekthi yomnikazi yilokho okufunwa umhlaba”, umnyango wephrojekthi encane ye-polyethylene egcwele ukuminyana uthuthukise kakhulu ukuphathwa, kanye nenhliziyo yokufaka – uhlelo lokusabela Ngohlelo lwegranulation njengomgogodla, uhlelo lokuhlola amapayipi, ukucushwa kweyunithi yomoya kanye nenqubo yeyunithi yomoya. ukulayishwa kwe-catalyst yokucwengisiswa kwempahla eluhlaza, kanye nokulungisa iphutha 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 labaklami nabashayelayo linamathela kusayithi, linomuzwa wokuba nesibopho “sokuhlala uqinisekile”, futhi liphuma lonke ukubambisana ukuze lixazulule izingozi ezifihliwe enqubweni yokuhlola ngaphambilini, futhi liqinisekise ngokucophelela isimo sokulungiselela sohlelo lwe-catalyst , Umjovo wesistimu ye-chromocene, kanye nokusetshenziswa 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.
