Uruganda rwa Guangdong Petrochemical rupima toni 800.000 ku mwaka ni rwo ruganda rwa mbere rwa PetroChina rupima poliyetinamu rufite "umutwe umwe n'imirizo ibiri", kandi ni narwo ruganda rwa kabiri rupima poliyetinamu rufite ubushobozi bwinshi mu Bushinwa. Iki gikoresho gikoresha uburyo bwa UNIPOL n'uburyo bwa gaze-phase fluidized bed process. Gikoresha ethylene nk'ibikoresho by'ibanze kandi gishobora gukora ubwoko 15 bwa polyethylene ya LLDPE na HDPE. Muri byo, uduce twa polyethylene dupima poliyetinamu dukozwe mu ifu ya polyethylene ivanze n'ubwoko butandukanye bw'inyongera, zishyushye ku bushyuhe bwinshi kugira ngo zigere ku rugero rwo gushonga, kandi hakoreshejwe imashini ikoresha screw ebyiri n'ipompo y'ibikoresho ishongeshejwe, binyura mu gishushanyo hanyuma bigatunganywa munsi y'amazi n'icyuma gikata. Guteranya granulation. Mu bihe bisanzwe by'akazi, umurongo umwe ushobora gukora toni 60.6 za polyethylene pellets ku isaha.
Bivugwa ko inzira yo gukora ikoresha ethylene nk'ibikoresho by'ibanze na butene-1 cyangwa hexene-1 nk'itsinda rito kugira ngo rikore resins za polyethylene granular ziciriritse hamwe na resins zimwe na zimwe ziciriritse n'izikomeye. Kugeza ubu, umurongo wo gukora warangije neza igikorwa cyose cyo gutunganya polymerization-degassing-recycling-extrusion granulation, ibimenyetso by'ibicuruzwa birakenewe, kandi umutwaro w'umusaruro ugenda wiyongera buhoro buhoro. Umuyoboro wa 1 wa polyethylene wa Guangdong Petrochemical wa toni 800.000 ku mwaka uteganijwe gutangira gukora mu minsi 8.
Uruganda rwa polyethylene rwuzuye rwatangiye kuhakorera ku ya 14 Nzeri 2020. Mu gihe cy'ubwubatsi, ishami rishinzwe umushinga wa polyethylene wuzuye ryashyize imbaraga mu micungire y’icyitegererezo cy’ubuyobozi rusange, ingabo zihuriweho n’impande zose, ryashyize imbere umwuka wa peteroli n’umwuka wa Daqing, kandi rifata iya mbere mu gutera ridategereje cyangwa ngo ritegereze aho umushinga uherereye. Ubushyuhe bwinshi n’ubushuhe bwinshi, imvura n’inkubi y’umuyaga n’izindi ngaruka mbi. Ishami ry’ishyaka ry’ishami rishinzwe umushinga w’igice ryashyize imbaraga mu bikorwa by’igihome cy’intambara, kandi rikurikirana amarushanwa y’abakozi nka “gukora cyane iminsi 60”, “kwiruka mu gihembwe cya kane, no gutsinda 3.30″., ryubatse umurongo uhamye wo kurinda umutekano n’ubwiza, ryananiwe “kwihutisha” kubaka umushinga, kandi amaherezo ryageze ku ntego yo kugeza igikoresho hagati ku ya 27 Kamena 2022, yamaze amezi 21.5.
Mu cyiciro cyo gutegura umusaruro, hakurikijwe imyumvire yo "gutanga ibikoresho ariko ntabwo ari inshingano", no gukomeza gushyira mu bikorwa igitekerezo cy'uko "intsinzi y'umushinga wa nyir'ubwite ni cyo isi ishaka", ishami rishinzwe imishinga ya polyethylene yuzuye ryarushijeho kunoza imicungire, n'ishingiro ry'imitangire - uburyo bwo gusubiza. Hamwe na sisitemu yo gukurura ingano y'ibikoresho, igeragezwa ry'imizigo y'ibikoresho binini, gukurura no gufunga imiterere y'imiyoboro y'amashanyarazi, gutunganya ibikoresho fatizo, no gutunganya ibikoresho by'amashanyarazi mu buryo bunoze byakozwe mu buryo bunoze. Abakozi b'ubuyobozi bavanze ibikorwa byimbitse aho bakorera kugira ngo bihutishe "iperereza ritatu n'imyanzuro ine" n'ibicuruzwa bya PSSR bigurishwa. Ishami rishinzwe imishinga ya polyethylene yuzuye ryahoranye "ihuza ku nshuro imwe" na nyir'ubwite. Itsinda rishinzwe gushushanya no kuyobora rikomeza gukora neza aho hantu, rifite inshingano zo "guhora wizeye", kandi rikora ibishoboka byose kugira ngo rikemure ibibazo byihishe mu igeragezwa mbere yo kurisuzuma, kandi ryemeza neza uko sisitemu ya catalyst ihagaze, Gushyira sisitemu ya chromocene, no gushyira mu bikorwa neza ibipimo bitandukanye by'imikorere byashyizeho urufatiro rukomeye rwo gutangiza neza igikoresho icyarimwe.
Mu cyiciro cya mbere cy’imikorere y’uruganda, ishami rishinzwe imishinga ya polyethylene yuzuye rizashimangira gukorana umutima wose kugira ngo uruganda rugere mu gihe cy’umusaruro n’imikorere ihamye, rusoze isuzuma ry’imikorere, kandi rugire uruhare mu iterambere ry’ikigo.
