I-Reactor yenqubo ye-Unipol ingumkhumbi we-cylindrical vertical pressure one-diameter engaphezulu ekhulisiwe, engasetshenziswa endaweni ene-supercondensed, okuthiwa inqubo ye-supercondensed state gas-phase fluidized bed process (SCM).
I-MFR ye-homo-polymer ekhiqizwa ngokwezimboni ngenqubo ye-Unipol ingu-0.5 ~ 100g/10min, futhi ingxenye enkulu ye-ethylene comonomer ku-co-polymer engahleliwe ingafinyelela ku-5.5%;i-co-polymer engahleliwe ye-propylene kanye ne-1-butene yenziwe ngezimboni (igama lokuhweba CE -FOR), lapho ingxenye enkulu yenjoloba ingaba phezulu njenge-14%;ingxenye enkulu ye-ethylene ku-co-polymer yomthelela ekhiqizwa inqubo ye-Unipol ingafinyelela ku-21% (ingxenye enkulu yenjoloba i-35%).
4. I-Horizone Craft
Inqubo ye-Horizone ithuthukiswa ngesisekelo sobuchwepheshe benqubo yesigaba segesi ye-Innovene, futhi kunokufana okuningi phakathi kwakho kokubili, ikakhulukazi umklamo we-reactor ngokuyisisekelo uyafana.
Umehluko omkhulu phakathi kwalezi zinqubo ezimbili ukuthi ama-reactor amabili enqubo ye-Horizone ahlelwa ngokuma phezulu naphansi, okukhiphayo kwe-reactor yokuqala kugeleza ngokuqondile kudivayisi yokukhiya umoya ngamandla adonsela phansi, bese kufakwa ku-reactor yesibili nge-propylene pressure. ;kuyilapho ukusabela okubili kwenqubo ye-Innovene Ama-reactors ahlelwa ngokuhambisana futhi avundlile, futhi okukhiphayo kwe-reactor yokuqala kuthunyelwa kuqala kumhlali endaweni ephakeme, bese i-polymer powder ehlukanisiwe ifakwa kukhiye womoya ngamandla adonsela phansi, bese ithunyelwa ku-reactor yesibili ngokucindezela kwe-propylene.
Uma kuqhathaniswa nalokhu kokubili, inqubo ye-Horizone ilula ekwakhiweni futhi idla amandla amancane.Ngaphezu kwalokho, i-catalyst esetshenziselwa inqubo ye-Horizone idinga ukulungiswa, eyenziwe ibe yi-slurry nge-hexane, futhi inani elincane le-propylene lengezwe ukuze kusetshenziswe i-prepolymerization, ngaphandle kwalokho i-powder enhle emkhiqizweni izokwanda, i-fluidity izokwehla, kanye nokusebenza kwe-co-polymerization reactor kuzoba nzima.
Inqubo ye-Horizone gas phase PP ingakhiqiza uhla olugcwele lwemikhiqizo.Uhlu lwe-MFR lwemikhiqizo ye-homo-polymer luyi-0.5~300g/10min, kanti ingxenyenamba ye-ethylene mass yama-co-polymers angahleliwe ifinyelela ku-6%.I-MFR yemikhiqizo ye-co-polymer yomthelela ingu-0.5 ~ 100g /10min, ingxenye enkulu yenjoloba iphezulu njengo-60%.
5. Inqubo ye-Spheripol
Inqubo ye-Spheripol isebenzisa inqubo ehlanganisiwe yesigaba se-liquid-bulk-gas phase, i-liquid phase loop reactor isetshenziselwa ukusabela kwe-prepolymerization kanye ne-homo-polymerization, futhi i-gas phase fluidized bed reactor isetshenziselwa ukusabela kwe-multiphase co-polymerization.Ingahlukaniswa ibe yindandatho eyodwa ngokusho kwamandla okukhiqiza kanye nohlobo lomkhiqizo.Kunezinhlobo ezine zamafomu okusabela kwe-polymerization, okuyizindandatho ezimbili, izindandatho ezimbili negesi eyodwa, nezindandatho ezimbili namagesi amabili.
Inqubo ye-Spheripol yesizukulwane sesibili yamukela uhlelo lwe-catalyst lwesizukulwane sesine, futhi izinga lokucindezela kokuklama kwe-prepolymerization kanye ne-polymerization reactors liyakhuphuka, ukuze ukusebenza komkhiqizo omusha kube ngcono, ukusebenza komkhiqizo omdala kuyathuthukiswa, futhi ibuye ihambisane ne-morphology, isotacticity kanye nesihlobo.Ukulawulwa kwesisindo samangqamuzana.
Uhlu lomkhiqizo wenqubo ye-Spheripol lubanzi kakhulu, i-MFR ingu-0.1 ~ 2 000g/10min, ingakhiqiza uhla oluphelele lwemikhiqizo ye-PP, okuhlanganisa ama-homo-polymers we-PP, ama-co-polymers angahleliwe nama-terpolymers, ama-co-polymers omthelela kanye nomthelela omkhulu -ama-polymers, ama-co-polymers angahleliwe angafinyelela ku-4.5% ethylene, ama-co-polymers omthelela angafinyelela ku-25% -40% ethylene, futhi isigaba senjoloba singafinyelela ku-40% -60%.

Umehluko omkhulu phakathi kwenqubo ye-Hypol II kanye nenqubo ye-Spheripol ukuklanywa kwe-reactor yesigaba segesi, futhi amanye amayunithi afaka i-catalyst kanye ne-prepolymerization ngokuyisisekelo ayafana nenqubo ye-Spheripol.Inqubo ye-Hypol II isebenzisa i-catalyst yesizukulwane sesihlanu (i-RK-catalyst), enomsebenzi ophezulu kakhulu Umsebenzi we-catalyst yesizukulwane sesine uphakeme izikhathi ezingu-2-3 kune-catalyst yesizukulwane sesine, esinokuzwela okuphezulu kwe-hydrogen modulation. futhi ingakhiqiza imikhiqizo enobubanzi obubanzi be-MFR.
Inqubo ye-Hypol II isebenzisa ama-loop reactor angu-2 kanye nesigaba segesi se-fluidized bed reactor ene-blade enyakazayo ukukhiqiza ama-homopolymers kanye nama-copolymers anomthelela, i-reactor yesibili iyisigaba segesi esakhiwe nge-fluidized bed reactor ene-blade enyakazayo Izimo zokusabela ze-loop reactor ku-HypolII. inqubo ingu-62~75℃, 3.0~4.0MPa, futhi izimo zokusabela zokukhiqizwa kwama-copolymers womthelela zingu-70~80℃, 1.7~2.0MPa.Inqubo ye-HypolII ingakhiqiza ama-homopolymers, ayikho i-copolymer Evamile kanye ne-block copolymer, ububanzi be-MFR bomkhiqizo ngu-0.3~80g/10min.I-homopolymer ifaneleka ukukhiqizwa kwefilimu esobala, i-monofilament, i-tape kanye ne-fiber, futhi i-copolymer ingasetshenziselwa ukukhiqizwa kwemishini yasendlini, izingxenye zezimoto nezimboni kanye nezingxenye.Izinga lokushisa eliphansi kanye nemikhiqizo enomthelela ophezulu.
7. Inqubo ye-Spherizone
Inqubo ye-Spherizone iyisizukulwane sakamuva sobuchwepheshe bokukhiqiza be-PP obuthuthukiswe yi-LyondellBasell ngesisekelo senqubo ye-Spheripol I.
I-multi-zone circulating reactor ihlukaniswe yaba izingxenye ezimbili zokusabela: ingxenye ekhuphukayo kanye nengxenye eyehlayo.Izinhlayiya ze-polymer zizungeza ezindaweni ezimbili zokusabela izikhathi eziningi.Izinhlayiya ze-polymer esigabeni esikhuphukayo zikhishwa ngokushesha ngaphansi kwesenzo segesi ejikelezayo bese zingena esiphepho phezulu kwesigaba esehlayo.Isihlukanisi, ukuhlukaniswa okuqinile kwegesi kwenziwa kusihlukanisi sesiphepho.Kukhona indawo yokuvimbela phezulu kwesigaba esehlayo ukuhlukanisa igesi yokusabela kanye nezinhlayiya ze-polymer.Izinhlayiya zehla ziye ezansi kwesigaba esehlayo bese zingena esigabeni esikhuphukayo ukuze ziqedele umjikelezo.Indawo yokuvimba Ukusetshenziswa kwe-reactor kungabona izimo zokusabela ezihlukene zesigaba esikhuphukayo kanye nesigaba esehlayo, futhi kwakhiwe izindawo ezimbili ezihlukene zokusabela.
8. Inqubo yepayipi ye-loop ye-Sinopec
Ngokwesisekelo sokugaya nokumunca ubuchwepheshe obungenisiwe, i-Sinopec ithuthukise ngempumelelo inqubo ye-PP yenqwaba yesigaba se-loop-pipe liquid kanye nobuchwepheshe bonjiniyela.Isebenzisa i-ZN catalyst eyakhiwe ngokwayo, i-monomer propylene ididiyelwe futhi yenziwe i-polymer ukukhiqiza imikhiqizo ye-homo-polymeric isotactic PP, i-propylene Ikhiqiza imikhiqizo ye-PP nomthelela ngokusebenzisa i-co-polymerization engahleliwe noma i-block co-polymerization nama-comonomers, okwenza i-PP yesizukulwane sokuqala iphelele. ubuchwepheshe be-70,000 kuya ku-100,000 t/a.
Ngalesi sisekelo, i-loop yesizukulwane sesibili ye-loop PP eqedela inqubo yobuchwepheshe be-200,000 t/a gas-phase reactor iye yathuthukiswa, engakhiqiza imikhiqizo yokusabalalisa i-bimodal kanye nama-co-polymers womthelela ophezulu.
Ngo-2014, iphrojekthi yocwaningo ye-Sinopec "yezitimela eziyishumi" - "isizukulwane sesithathu sokuphathwa kwemvelo PP ephelele ukuthuthukiswa kobuchwepheshe" eyenziwa ngokuhlanganyela yiSinopec Beijing Chemical Research Institute, iSinopec Wuhan Branch kanye neSinopec Huajiazhuang Refining and Chemical Branch yaphasisa ukuhlolwa kobuchwepheshe okuhlelwe ngu. Ukulinganisa kwenkampani China Petrochemical CorporationLolu hlelo oluphelele lobuchwepheshe lusekelwe ku-catalyst ezithuthukisiwe, ubuchwepheshe be-electron donor yangaphandle ye-asymmetric kanye ne-propylene-butylene yezingxenye ezimbili ze-co-polymerization ubuchwepheshe obungahleliwe, futhi kwakhiwe isethi yezobuchwepheshe ye-loop PP yesizukulwane sesithathu.Lobu buchwepheshe bungasetshenziswa ukukhiqiza i-homo-polymerization, i-ethylene-propylene co-polymerization engahleliwe, i-propylene-butylene co-polymerization engahleliwe kanye ne-PP eyi-co-polymer engathinteki, njll.
