Mafuta osakanizidwa ndi mankhwala ndi njira zina zatsopano ku China

Nthawi zambiri amapangidwa m'malo oyengamo mafuta, mafuta osakhwima amasinthidwa kukhala magawo osiyanasiyana monga naphtha, dizilo, palafini, petulo, ndi zotsalira zowira kwambiri.

Ukadaulo wa Crude oil-to-chemicals (COTC) umasintha mwachindunji mafuta osakhwima kukhala mankhwala amtengo wapatali m'malo mwamafuta oyendera.Imathandizira kutulutsa kwamankhwala kufika 70% mpaka 80% ya mbiya yamafuta osapanga mafuta opangira mankhwala ophatikizika poyerekeza ndi 8 ~ 10% m'malo oyeretsera osaphatikiza.

Pavuto lakuchepa kwa kubweza kwamafuta oyengedwa, ukadaulo wamafuta osakanizidwa ndi mankhwala (COTC) ukhoza kukhala sitepe yotsatira kwa oyenga.

Kuyeretsa mafuta osakhwima & kuphatikiza kwa petrochemical

Mphamvu zatsopano zoyenga ku Middle East ndi Asia zikuyang'ana kwambiri pakuyenga & kuphatikiza mankhwala m'zaka zaposachedwa.

Integrated refinery-petrochemical complex, monga PetroRabigh ku Saudi Arabia, imapanga pafupifupi 17-20% ya naphtha ya mankhwala pa mbiya ya mafuta.

Mafuta osakanizidwa omwe amapanga makemikolo ambiri:

Hengli Petrochemical refining & Chemical Integration Project imatha kusintha pafupifupi 42% pa mbiya yamafuta opanda mafuta kukhala mankhwala.

Kupatula Hengli, ena opanga ma mega-refiner omwe adayamba zaka zaposachedwa amatha kusintha mafuta osapsa kuti apange chakudya chokwanira kukhala chophatikizira cha nthunzi ndi chiŵerengero cha 40-70%.

Mphamvu yagawo: miliyoni mt/chaka

* nthawi imatha kusintha;magwero a data: CCFGroup, malipoti okhudzana ndi nkhani

Kukonzekera kwachindunji kwamafuta osakanizika pakuphwanyidwa kwa nthunzi:

Pakadali pano, ExxonMobil ndi Sinopec ndi makampani awiri okha omwe adakwanitsa kugwiritsa ntchito ukadaulo wapadziko lonse lapansi wamafuta osakhazikika.Idakhazikitsidwa mwalamulo ngati gawo loyamba lamankhwala padziko lonse lapansi lomwe limapangira mafuta osapsa ku Singapore mu 2014. Zokolola za ethylene + propylene zili pafupi.35%.

Pa Novembara 17, 2021, zidadziwika kuchokera ku Ofesi Yachidziwitso ya Sinopec kuti projekiti yayikulu ya Sinopec "Technology Development and Industrial Application of Ethylene Production ndi Cracking of Light Crude Oil" idayesedwa bwino mu Tianjin Petrochemical yake.Mafuta osakanizidwa amatha kusinthidwa mwachindunji kukhala ethylene, propylene ndi mankhwala ena, pozindikira kugwiritsa ntchito koyamba kwa mafakitale aukadaulo wamafuta osakhazikika ku China.Zokolola za mankhwala zimafika pozungulira48.24%.

Kukonzekera kwachindunji kwamafuta osakhazikika pakusweka kothandizira:

Pa Epulo 26, ukadaulo wosweka wamafuta osakanizidwa wopangidwa ndi Sinopec udayesedwa bwino ku Yangzhou Petrochemical Company, yomwe idasinthiratu mafuta osayera kukhala ma olefin opepuka, zonunkhira ndi mankhwala ena.

Izi zitha kusinthidwa kukhala mozungulira50-70%za mankhwala a mbiya ya mafuta osapsa.

Kupatula njira za COTC zopangidwa ndi Sinopec, makampani ena awiri akuluakulu amafuta akufunafunanso zopambana pakuyenga mafuta & makampani opanga mankhwala.

CNOOC-Fuhaichuang AGO kutsatsa ndi kupatukana

Pa Disembala 15, CNOOC Tianjin Chemical Research and Design Institute Co., Ltd. (pambuyo pano imatchedwa CNOOC Tianjin Institute of Development) ndi Fujian Fuhaichuang Petrochemical Co., Ltd. mgwirizano wa layisensi ku Zhangzhou City, Province la Fujian.

Mgwirizanowu umaphatikizapo 2 miliyoni mt/chaka adsorption separation project ndi 500kt/chaka heavy aromatics lightweight project, zomwe zimadziwika koyamba kuti ukadaulo woyamba waku China wolekanitsa dizilo wazindikira matani miliyoni ndi ma seti athunthu akugwiritsa ntchito kwathunthu.

Mu July 2020, luso anali bwinobwino ntchito kwa nthawi yoyamba mu 400kta AGO adsorption ndi kulekana mafakitale chomera Binzhou City, Province Shandong.

Saudi Aramco TC2C TM, ndondomeko ya CC2C TM ndi polojekiti ya Yanbu

Pa Januware 18, 2018, Saudi Aramco, kudzera mu kampani yake yothandizidwa ndi Saudi Aramco Technologies, idasaina mgwirizano wamagulu atatu a Joint Development Agreement (JDA) ndi CB&I, wotsogola wotsogola ku US pazaukadaulo ndi zomangamanga pamakampani opanga magetsi, ndi Chevron. Lummus Global (CLG), mgwirizano pakati pa CB&I ndi Chevron USA Inc., komanso mtsogoleri wotsogola waukadaulo waukadaulo.Cholinga cha njirayi ndikusintha 70-80% pa mbiya yamafuta kukhala mankhwala.

Pa Januware 29, 2019, Saudi Aramco, kudzera mu kampani yake yothandizidwa ndi Saudi Aramco Technologies, lero yasaina mgwirizano wa Joint Development and Collaboration Agreement (JDCA) ndi Axens ndi TechnipFMC kuti ifulumizitse chitukuko ndi malonda a kampaniyo Catalytic Crude to Chemicals (CC2C TM TM). teknoloji.

Ukadaulo wa CC2C TM uli ndi kuthekera kowonjezera kwambiri magwiridwe antchito ndi zokolola za kupanga mankhwala, kutembenuza kuposa 60% ya mbiya yamafuta osakanizidwa kukhala mankhwala.

Mu Okutobala 2020, SABIC idalengeza kuti ikuwunikanso ndikuwonjezera masomphenya ake a projekiti yamafuta osakanizidwa ndimafuta (COTC) ku Yanbu, Saudi Arabia ndi kuphatikiza kwa zomangamanga zomwe zilipo.

Kampaniyo idauza Saudi stock exchange kuti ikufuna kukulitsa projekitiyi limodzi ndi Saudi Aramco "kuphatikiza mapulogalamu omwe alipo opititsa patsogolo ukadaulo wamankhwala opangira mankhwala komanso kuphatikiza zida zomwe zilipo" ngati njira yopititsira patsogolo phindu pamsika wapano. zoopsa.Kumayambiriro kwa chaka chino, Aramco idagula 70% ku SABIC ndipo kuyambira pamenepo makampani onsewa achepetsa kwambiri mapulani ake a capex chifukwa cha zovuta za COVID-19.

Pulojekiti ya Yanbu COTC poyamba inkaganiziridwa zaka zitatu zapitazo kuti iwononge migolo ya 400,000 tsiku lililonse lamafuta osakanizidwa kukhala matani 9 miliyoni pachaka a mankhwala ndi mafuta oyambira, ndikuyamba kuyembekezeredwa mu 2025. kuwongoleranso, ndipo mtengo woyembekezeredwa wa projekiti wa $ 20 biliyoni ukuyembekezeka kutsika pomwe pulojekitiyi ikuyesa kumanga nyumba yatsopano ndikudalira malo omwe alipo pafupi m'malo mwake.

Reliance Industries Kuti Akhazikitse Ku India COTC Complex

Reliance Industries ikukonzekera kuyika $ 9.8 biliyoni pamalo opangira mafuta-to-chemicals (COTC) pamalo akampani a Jamnagar ku India, malinga ndi lipoti la Chemical Week mu Novembala 2019.

Reliance ikufuna kupanga mayunitsi a COTC kuphatikiza chophatikizira chophatikizira zakudya zambiri ndi multi-zone catalytic cracking (MCC).Kampaniyo ikukonzekeranso kusintha gawo lomwe lilipo la fluid catalytic cracking (FCC) kuti likhale lamphamvu kwambiri FCC (HSFCC) kapena Petro FCC unit, kuti muwonjezere zokolola za ethylene ndi propylene.

Complex ya MCC/HSFCC idzakhala ndi mphamvu yophatikiza 8.5 miliyoni metric tons/chaka (Mln mt/yr) ya ethylene ndi propylene, komanso mphamvu yotulutsa yonse ya 3.5 Mln mt/yr ya benzene, toluene, ndi xylenes.Idzakhalanso ndi mphamvu yophatikiza 4.0 Mln mt/chaka ya para-xylene (p-xylene) ndi ortho-xylene.The steam cracker adzakhala ophatikizana mphamvu 4.1 Mln mt/yr wa ethylene ndi propylene, ndi kudyetsa C4s crude kudzala 700kt/chaka butadiene m'zigawo.
