I-Guangdong Petrochemical's 800,000-ton/year full-density polyethylene plant sisityalo sokuqala se-polyethylene esixineneyo sase-PetroChina esine-"ntloko enye kunye nomsila emibini" ulungelelwaniso lwemigca emibini, kwaye ikwayeyesibini isityalo se-polyethylene esinoxinano olupheleleyo esinomthamo omkhulu wemveliso e-China. Isixhobo samkela inkqubo ye-UNIPOL kunye ne-single-reactor gas-phase fluidized bed process. Isebenzisa i-ethylene njengeyona nto iphambili kwaye inokuvelisa iindidi ezili-15 ze-LLDPE kunye ne-HDPE ye-polyethylene. Phakathi kwazo, i-polyethylene resin particles epheleleyo yenziwe nge-polyethylene powder exutywe kunye neentlobo ezahlukeneyo zezongezo, zifudunyezwe kwiqondo lokushisa eliphezulu ukuze zifike kwindawo etyhidiweyo, kwaye phantsi kwesenzo se-twin-screw extruder kunye nempompo yegesi etyhidiweyo, zidlula kwi-template kwaye zicutshungulwe phantsi kwamanzi ngumsiki. Ukwakhiwa kwegranulation. Ngaphantsi kweemeko eziqhelekileyo zokusebenza, umgca omnye unokuvelisa iitoni ezingama-60.6 ze-polyethylene pellets ngeyure.
Kubikwa ukuba inkqubo yomgca wemveliso isebenzisa i-ethylene njengeyona nto iphambili kunye ne-butene-1 okanye i-hexene-1 njenge-comonomer ukuvelisa i-linear low density kunye ne-medium and high-density polyethylene granular resins. Njengokuba ngexesha lokushicilela, umgca wokuvelisa ufezekise ngempumelelo yonke inkqubo yokucoca-i-polymerization-degassing-recycling-extrusion granulation, izikhombisi zemveliso zifanelekile, kwaye umthwalo wemveliso ukhula ngokuthe ngcembe. I-Guangdong Petrochemical's 800,000-toni/nyaka yomgca wesityalo se-polyethylene esigcweleyo ndicwangciselwe ukuqalisa ukusebenza kwiintsuku ezisi-8.
Isityalo se-polyethylene esipheleleyo saqala kwi-site ngoSeptemba 14, 2020. Ngexesha lokwakha, isebe leprojekthi ye-polyethylene ye-full-density sub-project yanikezela ngokudlala ngokupheleleyo kwiinzuzo zemodeli yokulawula edibeneyo "yesebe-jikelele", imibutho ehlangeneyo evela kuwo onke amaqela, iqhubela phambili ngokupheleleyo umoya we-oyile kunye nomoya we-Daqing, kwaye yathatha iphulo ngaphandle kokulinda okanye indawo yokuhlasela. Ukushisa okuphezulu kunye nomswakama ophezulu, imvula kunye ne-typhoon kunye nezinye iziphumo ezibi. Isebe leqela lesebe leprojekthi ephantsi linike umdlalo opheleleyo kwindima yenqaba yedabi, kwaye ngokulandelelana liququzelele uthotho lokhuphiswano lwabasebenzi olufana “nokusebenza nzima kangangeentsuku ezingama-60”, “ukubaleka kwikota yesine, nokuphumelela i-3.30″. I-2022, eyathatha iinyanga ze-21.5.
Kwinqanaba lokulungiselela imveliso, ngokuhambelana nesimo sengqondo "sokunikezela ngofakelo kodwa ingelulo uxanduva", kunye nokuqhubeka nokuziqhelanisa nombono "wempumelelo yeprojekthi yomnini yinto efunwa lihlabathi", icandelo leprojekthi encinci ye-polyethylene yoxinaniso luphucule ngakumbi ulawulo, kunye nentliziyo yofakelo - inkqubo yokuphendula kunye nenkqubo yegranulation njengeyona nto iphambili, inkqubo yovavanyo lombhobho, ukunyanzeliswa kwenkqubo yomthwalo weyunithi kunye nenkqubo yomoya. Ukulayishwa kwe-catalyst yokulungiswa kwempahla ekrwada, kunye nokulungiswa ngokudibeneyo kwezixhobo zombane kuqhutywe ngendlela ehlelekile. Abasebenzi bolawulo badityaniswe nemisebenzi ekwisiza ngobunzulu ukukhawulezisa ngakumbi "uphando oluthathu kunye nezigqibo ezine" izinto zokugqibela kunye nezinto zokuthengisa zePSSR. Isebe le-sub-project ye-polyethylene egcweleyo ihlale igcina "i-resonance kwi-frequency efanayo" kunye nomnini. Uyilo kunye neqela lokuqhuba linamathela kwindawo, ngemvakalelo yoxanduva "lokuhlala uqinisekile", kwaye liphuma konke ukuze lisebenzisane ukusombulula iingozi ezifihliweyo kwinkqubo yovavanyo lwangaphambili, kwaye uqinisekise ngononophelo imeko yolungiselelo lwenkqubo ye-catalyst , Isitofu senkqubo yechromocene, kunye nokuphunyezwa okungqongqo kweeparamitha zenkqubo ziye zabeka isiseko esiluqilima sokuqalisa ngempumelelo isixhobo ngexesha elinye.
Kwinqanaba lokuqala lokusebenza kwezityalo, isebe leprojekthi encinci ye-polyethylene yoxinaniso olupheleleyo luya kugxininisa ekukhonzeni ngentliziyo epheleleyo ukuqinisekisa ukuba isityalo singena kwixesha elizinzileyo lokuvelisa kunye nokusebenza, lugqibe uvavanyo lokusebenza, kwaye lufake isandla ekuphuhliseni umgangatho ophezulu wenkampani.
