Chirimwa chepolyethylene cheGuangdong Petrochemical chinorema matani 800,000 pagore ndicho chirimwa chekutanga chePetroChina chine mativi maviri e "musoro mumwe nemiswe miviri", uye ndicho chirimwa chechipiri chine mativi maviri e polyethylene chine simba guru rekugadzira muChina. Chishandiso ichi chinoshandisa nzira yeUNIPOL uye nzira ye single-reactor gas-phase fluidized bed process. Chinoshandisa ethylene sechinhu chikuru uye chinogona kugadzira mhando gumi neshanu dzezvinhu zveLLDPE neHDPE polyethylene. Pakati pazvo, zvikamu zve polyethylene resin zvakagadzirwa nehupfu hwe polyethylene hwakasanganiswa nemhando dzakasiyana dzezvinowedzera, zvinopiswa pakupisa kwakanyanya kusvika padanho rakanyungudutswa, uye pasi pekushanda kwe twin-screw extruder ne molded gear pombi, zvinopfuura nemu template uye zvinogadziriswa pasi pemvura nemuchina wekucheka. Kuumbwa kwegranulation. Mumamiriro ekushanda akajairwa, mutsetse mumwe chete unogona kugadzira matani 60.6 e polyethylene pellets paawa.
Zvinonzi nzira yekugadzira mutsetse inoshandisa ethylene sezvinhu zvikuru uye butene-1 kana hexene-1 se comonomer kugadzira linear low-density uye mamwe ma polyethylene granular resins ari pakati nepakati uye akakwirira. Pakazosvika nguva yekuburitswa kwemashoko, mutsetse wekugadzira wapedza basa rese rekuchenesa-polymerization-degassing-recycling-extrusion granulation, zviratidzo zvechigadzirwa zvakabvumidzwa, uye mutoro wekugadzira uri kuwedzera zvishoma nezvishoma. Guangdong Petrochemical's 800,000-ton/year full-density polyethylene plant line I yakarongerwa kutanga kushanda mumazuva masere.
Chivako chepolyethylene chakatanga kushanda panzvimbo yacho musi wa14 Gunyana, 2020. Munguva yekuvaka, dhipatimendi re "full-density polyethylene sub-project" rakashandisa zvizere mabhenefiti e "general-department" integrated management model, mauto akabatana kubva kumapato ese, rakafambisa zvizere mweya wemafuta nemweya weDaqing, uye rakatora danho rekurwisa pasina kumirira kana kuvimba nenzvimbo yepurojekiti. Kupisa kwakanyanya uye hunyoro hwakawanda, kunaya kwemvura nedutu nezvimwe zvinokanganisa. Bazi rebato redhipatimendi re "sub-project" rakashandisa zvizere basa renhare yehondo, uye rakaronga zvakatevedzana makwikwi evashandi akadai se "kushanda nesimba kwemazuva makumi matanhatu", "kumhanya kwekota yechina, uye kuhwina 3.30″. , vakavaka mutsetse wakasimba wekudzivirira kuchengetedzeka uye kunaka, vakashaya "kukurumidza" kwekuvakwa kwepurojekiti, uye pakupedzisira vakawana pakati pekuendeswa kwechigadzirwa musi wa27 Chikumi, 2022, uyo wakatora mwedzi 21.5.
Muchikamu chekugadzirira kugadzirwa, zvichienderana nemafungiro ekuti "kupa kuiswa asi kwete mutoro", uye kuramba uchiita pfungwa yekuti "kubudirira kwepurojekiti yemuridzi ndizvo zvinodiwa nenyika", dhipatimendi repasi rose re polyethylene sub-project rakavandudza manejimendi, uye moyo wekuisa - system yekupindura. Nehurongwa hwe granulation sehwakakosha, kuyedzwa kwekutakura zvinhu zvikuru, kutorwa kwepickling uye kusimba kwemhepo ye process pipeline system, kurodha catalyst ye raw material refine, uye kugadzirisa majoint electrical instruments kwakaitwa nenzira yakarongeka. Vashandi vemanejimendi vakapindirana nemabasa ari panzvimbo yacho zvakadzama kuti vakurumidze "kuferefeta katatu uye kusarudzwa kunana" kwezvinhu zvekupedzisira uye zvinhu zvekutengesa zvePSSR. Dhipatimendi repasi rose re polyethylene sub-project ragara richichengetedza "resonance panguva imwe chete" nemuridzi. Chikwata chekugadzira nekutyaira chinonamatira panzvimbo iyi, nepfungwa yekuti "gara uine chokwadi", uye chinoshanda nesimba kuti chigadzirise njodzi dzakavanzwa mukuita kwekuyedza, uye kusimbisa nekungwarira mamiriro ekugadzirira kwesystem ye catalyst. Kuiswa kwe chromocene system, uye kushandiswa kwakasimba kwematanho akasiyana-siyana ekuita kwakaisa hwaro hwakasimba hwekutanga kwemuchina uyu panguva imwe chete.
Padanho rekutanga rekushanda kwefekitori, dhipatimendi remapurojekiti epolyethylene akazara richasimbirira pakushanda nemoyo wese kuti rive nechokwadi chekuti fekitori iri inopinda munguva yekugadzirwa nekushanda kwakasimba, kupedzisa ongororo yekushanda, uye kubatsira mukuvandudzwa kwemhando yepamusoro kwekambani.
