Ngokuqhelekileyo xa icutshungulwa kwindawo yokuhluza ioli, i-oyile ekrwada iguqulwa ibe ngamaqhezu ahlukeneyo afana nenaphtha, idizili, i-kerosene, ipetroli, kunye nentsalela ebilayo ephezulu.
Itekhnoloji ye-oyile ekrwada ukuya kwiikhemikhali (COTC) iguqula ngokuthe ngqo i-oyile ekrwada iye kwimichiza yexabiso eliphezulu endaweni yezibaso zothutho zesintu.Ivumela imveliso yeekhemikhali ifikelele kwi-70% ukuya kwi-80% yebhere ye-oyile ekrwada evelisa isondlo sekhemikhali ngokuchasene ne-8 ~ 10% kwindawo yokucoca engadityaniswanga.
Kwingxaki yokuncipha kwembuyekezo kwiimveliso ze-oyile esulungekileyo, itekhnoloji ye-oyile ekrwada ukuya kwiikhemikhali (COTC) inokuba linyathelo elilandelayo eliya phambili labasulungekisi.
Ukusulungekiswa kwe-oyile ekrwada kunye nokudityaniswa kwepetrochemical
Amandla okucoca amatsha kuMbindi Mpuma naseAsia agxile ekusulungekiseni nasekudityanisweni kweekhemikhali kwiminyaka yakutshanje.
I-complex ye-refinery-petrochemical complex, efana ne-PetroRabigh e-Saudi Arabia, ivelisa malunga ne-17-20% ye-naphtha yeekhemikhali nge-barrel yeoli.
I-oyile ekrwada ivelisa eyona michiza mikhulu:
I-Hengli Petrochemical yokusulungekiswa kunye neprojekthi yokuhlanganisa imichiza inokuguqula malunga ne-42% ngomphanda we-oyile ekrwada ibe yimichiza.
Ngaphandle kwe-Hengli, abanye abasulungeki be-mega abaqalwe kwiminyaka yakutshanje banokuguqula i-oyile ekrwada ukuba ivelise ukutya okuninzi kwi-cracker yomphunga ngomlinganiselo omalunga nama-40-70%.

Ukwenziwa ngokuthe ngqo kwe-oyile ekrwada ekuqhekekeni komphunga:
Okwangoku, i-ExxonMobil kunye ne-Sinopec kuphela kweenkampani ezimbini eziye zafumana ngempumelelo ukusetyenziswa kwe-oyile ekrwada yokukrazula umphunga kwihlabathi liphela.Yaziswa ngokusemthethweni njengeyunithi yokuqala yeekhemikhali yehlabathi eyenza ioli ekrwada eSingapore ngo-2014. Isivuno se-ethylene + propylene sijikeleze35%.
Ngomhla we-17 kaNovemba ka-2021, kwafundwa kwi-Ofisi yoLwazi yaseSinopec ukuba iprojekthi ephambili yeSinopec "Uphuhliso lweTekhnoloji kunye nosetyenziso lwezoShishino lweMveliso ye-Ethylene ngoKuqhekezwa kweOli eKrwada ekuKhanyayo" yavavanywa ngempumelelo kwi-Tianjin Petrochemical yayo.I-oyile ekrwada inokuguqulwa ngokuthe ngqo kwi-ethylene, ipropylene kunye nezinye iikhemikhali, ukuqonda usetyenziso lokuqala lwefektri ye-oyile ekrwada yokuqhekeka iteknoloji eTshayina.Imveliso yeekhemikhali ifikelela ngeenxa zonke48.24%.
Ukusetyenzwa ngokuthe ngqo kwe-oyile ekrwada kwi-catalytic cracking:
Nge-26 ka-Epreli, itekhnoloji ye-oyile ekrwada yokuqhekeka itekhnoloji ngokuzimeleyo ephuhliswe yiSinopec yavavanywa ngempumelelo kwiNkampani ye-Yangzhou Petrochemical Company, eyaguqula ngokuthe ngqo ioyile ekrwada ibe yi-olefin ekhanyayo, i-aromatics kunye nezinye iikhemikhali.
Le nkqubo ingaguqulela kujikelezo50-70%yeekhemikhali zomphanda we-oyile ekrwada.
Ngaphandle kweendlela zeCOTC eziphuhliswe yiSinopec, ezinye iinkampani ezimbini zeoyile zikwafuna impumelelo ekusulungekisweni kweoyile kunye nakwishishini lemichiza.

CNOOC-Fuhaichuang AGO adsorption kunye nokwahlula
NgoDisemba 15, iCNOOC Tianjin Chemical Research and Design Institute Co., Ltd. (emva koku kubhekiselwa kuyo njengeCNOOC Tianjin Institute of Development) kunye neFujian Fuhaichuang Petrochemical Co., Ltd. batyikitye iseti epheleleyo yegesi ye-atmospheric (AGO) i-adsorption kunye nokwahlula ubuchwepheshe. ikhontrakthi yelayisensi kwiSixeko saseZhangzhou, kwiPhondo laseFujian.
Ikhontrakthi ibandakanya 2 million mt / ngonyaka adsorption iprojekthi yokwahlula kunye 500kt / ngonyaka enzima aromatics iprojekthi lightweight, ephawula okokuqala ukuba China yokuqala iteknoloji yokwahlula idizili adsorption uye waqonda iitoni million kunye neseti epheleleyo isicelo inkqubo epheleleyo.
NgoJulayi ka-2020, iteknoloji isetyenziswe ngempumelelo okokuqala kwi-adsorption ye-400kta AGO kunye nokwahlula indawo yoshishino kwiSixeko saseBinzhou, kwiPhondo laseShandong.
ISaudi Aramco TC2C TM, inkqubo yeCC2C TM kunye neprojekthi yeYanbu
NgoJanuwari 18, 2018, iSaudi Aramco, ngokusebenzisa i-Saudi Aramco Technologies ephantsi kwayo, isayine iSivumelwano soPhuhliso oluManyeneyo (JDA) kunye ne-CB & I, umboneleli okhokelayo wase-US weteknoloji kunye neziseko zoshishino lwamandla, kunye neChevron. I-Lummus Global (CLG), intsebenziswano phakathi kwe-CB&I kunye ne-Chevron USA Inc., kunye nomnikezeli welayisensi yenkqubo yeteknoloji.Injongo yale nkqubo kukuguqula i-70-80% ngebhere yeoli kwiikhemikhali.
NgoJanuwari 29, 2019, iSaudi Aramco, ngenkxaso yayo epheleleyo yaseSaudi Aramco Technologies, namhlanje ityikitye iSivumelwano soPhuhliso oluManyeneyo kunye neNtsebenziswano (JDCA) kunye ne-Axens kunye neTechnipFMC ukukhawulezisa uphuhliso kunye norhwebo lwenkampani yeCatalytic Crude to Chemicals (CC2C TM). iteknoloji.
Itekhnoloji yeCC2C TM inamandla okwandisa kakhulu ukusebenza kakuhle kunye nesivuno sokuveliswa kweekhemikhali, ukuguqula ngaphezu kwe-60% yombhobho yeoli ekrwada kwiikhemikhali.
Ngo-Okthobha ka-2020, i-SABIC yabhengeza ukuba ivavanya kwakhona kwaye kusenokwenzeka ukuba iyawandisa umbono wayo weprojekthi ye-oyile ekrwada ukuya kwiikhemikhali (COTC) eYanbu, eSaudi Arabia ngokudityaniswa kweziseko ezingundoqo ezikhoyo.
Inkampani ixelele iSaudi stock exchange ukuba iceba ukwandisa le projekthi ecaleni kweSaudi Aramco "ukubandakanya iinkqubo zophuhliso ezikhoyo zokuqhubela phambili itekhnoloji yeekhemikhali kunye nokudibanisa amaziko asele ekhona" njengendlela yokwandisa ixabiso ebusweni bentengiso yangoku. imingcipheko.Kwangoko kulo nyaka, i-Aramco ithenge i-70% yesabelo kwi-SABIC kwaye ukusukela ngoko zombini iinkampani ziye zanciphisa kakhulu izicwangciso ze-capex ngenxa yempembelelo ye-COVID-19.
Iprojekthi ye-Yanbu COTC yayinombono wokuqala kwiminyaka emithathu edlulileyo ukuba iqhube iibhareli ezingama-400,000 ngosuku lwe-oyile ekrwada kwi-9 yezigidi zeetoni ngonyaka kwimveliso yeekhemikhali kunye nesiseko se-oyile, kunye nokuqalwa okulindelweyo ngo-2025. Lo mhla ungatshintsha ebusweni boku. ukuhanjiswa ngokutsha, kunye neendleko zeprojekthi ezilindelekileyo zeedola ezingama-20 eebhiliyoni kulindeleke ukuba zehle njengoko iprojekthi ibaleka ulwakhiwo lweplanti entsha kwaye ixhomekeke kuncedo olukhoyo olukufutshane endaweni yoko.
Amashishini okuThembela ekuTyaleni imali kwi-Indian COTC Complex
IReliance Industries iceba ukutyala imali ezibhiliyoni ezisisi-9.8 zeedola kwindawo ekrwada-oyile ukuya kwiikhemikhali (COTC) kwindawo yenkampani yaseJamnagar eIndiya, ngokwengxelo yeVeki yeMichiza ngoNovemba ka-2019.
I-Reliance ijonge ukwakha iiyunithi ze-COTC ezibandakanya i-multi-feed steam cracker kunye neyunithi ye-multi-zone catalytic cracking (MCC).Inkampani ikwaceba ukuguqula iyunithi yesiza esele ikhona ye-fluid catalytic cracking (FCC) ibe yiFCC (HSFCC) okanye iyunithi yePetro FCC, ukunyusa imveliso ye-ethylene kunye nepropylene.
I-MCC/HSFCC complex iya kuba nomthamo odibeneyo we-8.5 yezigidi zeetoni ze-metric ngonyaka (Mln mt/yr) ye-ethylene kunye nepropylene, kunye ne-total extraction umthamo we-3.5 Mln mt/yr ye-benzene, toluene, kunye ne-xylenes.Kwakhona iya kuba nomthamo odibeneyo we-4.0 Mln mt/yr ye-para-xylene (p-xylene) kunye ne-ortho-xylene.I-cracker yomphunga iya kuba nomthamo odibeneyo we-4.1 Mln mt/yr ye-ethylene kunye nepropylene, kunye nokutya okukrwada kwe-C4s ukuya kwi-700kt / ngonyaka wesityalo sokutsalwa kwe-butadiene.
