Ngokuvamile uma ucutshungulwa endaweni ehluza uwoyela, uwoyela ongahluziwe uguqulwa ube izingxenyana ezihlukahlukene ezifana ne-naphtha, udizili, uphalafini, uphethiloli, nezinsalela ezibilayo eziphezulu.
Ubuchwepheshe be-Crude oil-to-chemicals (COTC) buguqula ngokuqondile uwoyela ongahluziwe ube amakhemikhali anenani eliphezulu esikhundleni sezibaseli zokuthutha zendabuko.Kwenza ukukhishwa kwamakhemikhali kufinyelele ku-70% kuya ku-80% womgqomo kawoyela ongahluziwe okhiqiza i-feedstock yamakhemikhali ngokuphambene no-8~10% endaweni yokuhluza engahlanganisiwe.
Enkingeni yokuncipha kwembuyiselo emikhiqizweni kawoyela ocolisisiwe, ubuchwepheshe be-crude oil-to-chemicals (COTC) bungaba isinyathelo esilandelayo esiya phambili sabacwengisisi.
Ukucwenga uwoyela ongahluziwe nokuhlanganiswa kwe-petrochemical
Amakhono amasha okucwenga eMpumalanga Ephakathi nase-Asia agxile ekucwengeni nasekuhlanganiseni amakhemikhali eminyakeni yamuva nje.
I-complex ye-refinery-petrochemical complex, efana ne-PetroRabigh e-Saudi Arabia, ikhiqiza cishe i-17-20% ye-naphtha yamakhemikhali emgqonyeni kawoyela.
Uwoyela ongahluziwe okhiqiza amakhemikhali aphezulu:
I-Hengli Petrochemical refining & chemical integration project ingaguqula cishe ama-42% emgqonyeni kawoyela ongahluziwe ibe amakhemikhali.
Ngaphandle kwe-Hengli, abanye abacwengi be-mega abaqalwe eminyakeni yamuva nje bebengakwazi ukuguqula uwoyela ongahluziwe ukuze ukhiqize ukudla okuphezulu kakhulu kumshini wokuqhumisa umusi ngesilinganiso esingama-40-70%.

Ukucutshungulwa okuqondile kukawoyela ongahluziwe ekuqhekekeni kwesitimu:
Njengamanje, i-ExxonMobil ne-Sinopec yizona kuphela izinkampani ezithole ngempumelelo ukusetshenziswa kwezimboni kobuchwepheshe bokuqhekeka kukawoyela ongahluziwe emhlabeni wonke.Yethulwe ngokusemthethweni njengeyunithi yamakhemikhali yokuqala emhlabeni ecubungula uwoyela ongahluziwe eSingapore ngo-2014. Isivuno se-ethylene + propylene siseduze35%.
NgoNovemba 17, 2021, kwafundwa eHhovisi Lolwazi laseSinopec ukuthi iphrojekthi ebalulekile yeSinopec “Ukuthuthukiswa Kobuchwepheshe Nokusetshenziswa Kwezimboni Zokukhiqizwa Kwe-Ethylene Ngokuqhekeka Kwamafutha Angahluziwe” yahlolwa ngempumelelo ku-Tianjin Petrochemical yayo.Uwoyela ongahluziwe ungaguqulwa ngokuqondile ube yi-ethylene, i-propylene namanye amakhemikhali, uqaphela ukusetshenziswa kwemboni yokuqala kobuchwepheshe bokuqhekeka kwesitimu sikawoyela ongahluziwe eChina.Isivuno samakhemikhali sifinyelela nxazonke48.24%.
Ukucutshungulwa okuqondile kukawoyela ongahluziwe ekuqhekekeni kwe-catalytic:
Ngomhla zingama-26 kuMbasa, ubuchwepheshe bokuqhekeka kukawoyela ongahluziwe owenziwe ngokuzimela owenziwe ngabakwaSinopec bahlolwa ngempumelelo eYangzhou Petrochemical Company, eyaguqula ngokuqondile uwoyela ongahluziwe waba ama-olefin alula, ama-aromatics namanye amakhemikhali.
Le nqubo ingaguqulela endaweni ezungezile50-70%wamakhemikhali omgqomo kawoyela ongahluziwe.
Ngaphandle kwemizila ye-COTC eyakhiwe yi-Sinopec, ezinye izinkampani zikawoyela ezimbili ezinkulu nazo zifuna impumelelo embonini yokuhluza uwoyela kanye namakhemikhali.

I-CNOOC-Fuhaichuang AGO isikhangiso nokuhlukaniswa
Ngomhla ziyi-15 kuZibandlela, i-CNOOC Tianjin Chemical Research and Design Institute Co., Ltd. (ngemuva kwalokhu ebizwa nge-CNOOC Tianjin Institute of Development) kanye ne-Fujian Fuhaichuang Petrochemical Co., Ltd. basayine isethi ephelele ye-atmospheric gasoil (AGO) yokukhangisa nobuchwepheshe bokuhlukanisa. inkontileka yelayisense e-Zhangzhou City, esifundazweni saseFujian.
Inkontileka ihlanganisa iphrojekthi yokuhlukanisa i-adsorption engu-2 million mt/ngonyaka kanye nephrojekthi ye-aromatics lightweight engu-500kt/ngonyaka, okuphawula okokuqala ukuthi ubuchwepheshe bokuqala base-China bokuhlukanisa i-adsorption ye-adsorption buthole amathani ayizigidi kanye namasethi aphelele wohlelo lokusebenza olugcwele.
NgoJulayi 2020, ubuchwepheshe basetshenziswa ngempumelelo okokuqala ngqa embonini yezokukhangisa nokuhlukanisa i-400kta AGO eDolobheni lase-Binzhou, esifundazweni saseShandong.
I-Saudi Aramco TC2C TM, inqubo ye-CC2C TM kanye nephrojekthi ye-Yanbu
NgoJanuwari 18, 2018, iSaudi Aramco, ngokusebenzisa inkampani ephethwe ngokuphelele iSaudi Aramco Technologies, isayine Isivumelwano Sokuthuthukiswa Kwabantu Bathathu (i-JDA) ne-CB&I, umhlinzeki oholayo ozinze e-US wezobuchwepheshe nengqalasizinda embonini yamandla, kanye ne-Chevron. I-Lummus Global (CLG), ibhizinisi elihlanganyelwe phakathi kwe-CB&I ne-Chevron USA Inc., kanye nomnikezeli welayisensi yobuchwepheshe benqubo ehamba phambili.Inhloso yale nqubo ukuguqula ama-70-80% emgqonyeni kawoyela abe amakhemikhali.
NgoJanuwari 29, 2019, i-Saudi Aramco, ngokusebenzisa inkampani ephethwe ngokuphelele i-Saudi Aramco Technologies, namuhla isayine Isivumelwano Sokuthuthukiswa Okuhlanganyelwe Nokubambisana (i-JDCA) ne-Axens kanye ne-TechnipFMC ukusheshisa ukuthuthukiswa nokudayiswa kwe-Catalytic Crude to Chemicals (CC2C TM) yenkampani. ) ubuchwepheshe.
Ubuchwepheshe be-CC2C TM bunamandla okwandisa kakhulu ukusebenza kahle kanye nesivuno sokukhiqizwa kwamakhemikhali, ukuguqula ngaphezu kuka-60% womgqomo kawoyela ongahluziwe ube amakhemikhali.
Ngo-Okthoba 2020, i-SABIC yamemezela ukuthi ibuyekeza kabusha futhi kungenzeka yandise umbono wayo wephrojekthi kawoyela ongahluziwe wokuya kumakhemikhali (COTC) eYanbu, eSaudi Arabia ngokuhlanganiswa kwengqalasizinda ekhona.
Le nkampani itshele iSaudi stock exchange ukuthi ihlela ukwandisa le phrojekthi eceleni kweSaudi Aramco "ukuze ifake izinhlelo ezikhona zokuthuthukisa ubuchwepheshe bamakhemikhali angcolile kanye nokuhlanganisa izikhungo ezikhona" njengendlela yokukhulisa inani ebusweni bemakethe yamanje. izingozi.Ngasekuqaleni konyaka, i-Aramco ithenge ingxenye engama-70% ku-SABIC futhi kusukela lapho zombili izinkampani zehlise kakhulu izinhlelo zayo ze-capex ngenxa yomthelela we-COVID-19.
Iphrojekthi ye-Yanbu COTC yacatshangelwa ukuthi eminyakeni emithathu edlule icubungule imiphongolo engu-400,000 ngosuku yesitoko sikawoyela ongahluziwe ibe amathani ayizigidi ezingu-9 ngonyaka wemikhiqizo yamakhemikhali kanye nesisekelo sikawoyela, okulindelwe ukuqala ngo-2025. Lolo suku lungase lushintshe uma kwenzeka lokhu ukuqondisa kabusha, futhi izindleko zephrojekthi ezilindelekile zamaRandi ayizigidi eziyizinkulungwane ezingama-20 kulindeleke ukuthi zehle njengoba iphrojekthi igwema ukwakhiwa kwesikhungo esisha futhi ithembele ezikhungweni ezikhona eziseduze kunalokho.
I-Reliance Industries Ukutshala imali ku-Indian COTC Complex
IReliance Industries ihlela ukutshala imali eyizigidi eziyizinkulungwane ezingama-9.8 zamarandi endaweni ye-crude-oil-to-chemicals (COTC) endaweni yenkampani yaseJamnagar eNdiya, ngokusho kombiko weChemical Week ngoNovemba 2019.
I-Reliance ihlose ukwakha amayunithi e-COTC afaka i-multi-feed steam cracker kanye neyunithi ye-multi-zone catalytic cracking (MCC).Inkampani futhi ihlela ukuguqula iyunithi yesayithi ekhona ye-fluid catalytic cracking (FCC) ibe iyunithi yokuqina kwe-FCC (HSFCC) noma i-Petro FCC, ukukhulisa isivuno se-ethylene ne-propylene.
Inxanxathela ye-MCC/HSFCC izoba namandla ahlanganisiwe angu-8.5 million metric tons/ngonyaka (Mln mt/yr) we-ethylene ne-propylene, kanye namandla okukhipha isamba esingu-3.5 Mln mt/unyaka we-benzene, toluene, nexylenes.Izoba nomthamo ohlanganisiwe we-4.0 Mln mt/unyaka we-para-xylene (p-xylene) kanye ne-ortho-xylene.I-steam cracker izoba nomthamo ohlangene we-4.1 Mln mt/yr we-ethylene ne-propylene, futhi iphakele ama-C4 aluhlaza ukuya endaweni yokukhipha i-butadiene engu-700kt/ngonyaka.
