ʻO ka hoʻomaʻemaʻe ʻaila a me ka hoʻohui ʻana i ka petrochemical
ʻO nā mana hoʻomaʻemaʻe hou i ka Middle East a me ʻAsia e kālele ana i ka hoʻomaʻemaʻe a me ka hoʻohui ʻana i nā kemika i nā makahiki i hala.
ʻO ka hui hoʻohuihui-petrochemical complex, e like me PetroRabigh ma Saudi Arabia, e hoʻopuka ma kahi o 17-20% o ka naphtha no nā kemika no ka pahu aila.
ʻO ka aila ʻaila e hana ana i nā kemika kiʻekiʻe loa:
Hiki i ka Hengli Petrochemical refining & chemical integration project ke hoʻololi ma kahi o 42% no kēlā me kēia pahu o ka aila ʻaila i nā kemika.
Ma waho aʻe o Hengli, hiki i kekahi mau mega-refiners i hoʻomaka i nā makahiki i hala iho nei ke hoʻololi i ka ʻaila ʻaila e hana i nā meaʻai nui loa i kahi pahū mahu me ka ratio ma kahi o 40-70%.

ʻO ka hana pololei ʻana o ka ʻaila maʻemaʻe i ka māwae mahu:
I kēia manawa, ʻo ExxonMobil lāua ʻo Sinopec nā hui ʻelua wale nō i hoʻokō kūleʻa i ka hoʻohana ʻana i ka ʻenehana o ka ʻenehana hoʻoheheʻe ʻaila ʻaila ma ka honua holoʻokoʻa.Ua hoʻokuʻu ʻia ʻo ia ma ke ʻano he hui kemika mua loa o ka honua e hana ana i ka ʻaila ʻaila ma Singapore ma 2014. Aia ka hua o ka ethylene + propylene a puni.35%.
Ma Nowemapa 17, 2021, ua aʻo ʻia mai ka Sinopec Information Office ua hoʻāʻo maikaʻi ʻia ka papahana koʻikoʻi a Sinopec "Technology Development and Industrial Application of Ethylene Production by Cracking of Light Crude Oil" i kāna Tianjin Petrochemical.Hiki ke hoʻololi pololei ʻia ka ʻaila i loko o ka ethylene, propylene a me nā mea ʻē aʻe, me ka ʻike ʻana i ka noi ʻoihana mua o ka ʻenehana hoʻoheheʻe ʻana i ka mahu ma Kina.Hiki i ka hua kemika a puni48.24%.
ʻO ka hana pololei ʻana o ka ʻaila ʻaila ma ka catalytic cracking:
Ma ka lā 26 ʻApelila, ua hoʻāʻo maikaʻi ʻia ka ʻenehana ʻenehana catalytic cracking i hoʻomohala kūʻokoʻa e Sinopec ma Yangzhou Petrochemical Company, nāna i hoʻololi pololei i ka ʻaila i loko o nā olefins māmā, nā mea ʻala a me nā mea ʻē aʻe.
Hiki i kēia kaʻina hana ke hoʻololi a puni50-70%o na kinikini o ka barela aila.
Ma waho aʻe o nā ala COTC i hoʻomohala ʻia e Sinopec, ke ʻimi nei nā hui ʻaila nui ʻelua i nā holomua i ka hoʻomaʻemaʻe aila a me ka ʻoihana kemika.

CNOOC-Fuhaichuang AGO adsorption a kaawale
Ma Kekemapa 15, CNOOC Tianjin Chemical Research and Design Institute Co., Ltd. (ma ia hope aku i kapa ʻia ʻo CNOOC Tianjin Institute of Development) a me Fujian Fuhaichuang Petrochemical Co., Ltd. i kau inoa i kahi hui piha o ka atmospheric gasoil (AGO) adsorption a me ka ʻenehana hoʻokaʻawale.

Saudi Aramco TC2C TM, kaʻina CC2C TM a me ka papahana Yanbu
Ma Ianuali 18, 2018, Saudi Aramco, ma o kāna ʻoihana paʻa ponoʻī ʻo Saudi Aramco Technologies, ua kau inoa i kahi hui ʻekolu hui Joint Development Agreement (JDA) me CB&I, kahi alakaʻi alakaʻi o ka ʻenehana a me nā ʻenehana no ka ʻoihana ikehu, a me Chevron. ʻO Lummus Global (CLG), he hui hui ma waena o CB&I a me Chevron USA Inc., a me kahi laikini ʻenehana kaʻina hana.ʻO ka pahuhopu o kēia kaʻina hana ʻo ia ka hoʻololi ʻana i ka 70-80% no ka barela o ka aila i kemika.
Ma Ianuali 29, 2019, ua hoʻopaʻa inoa ʻo Saudi Aramco, ma o kāna ʻoihana paʻa holoʻokoʻa ʻo Saudi Aramco Technologies, i kēia lā i kahi Joint Development and Collaboration Agreement (JDCA) me Axens a me TechnipFMC e hoʻolalelale i ka hoʻomohala ʻana a me ke kālepa ʻana o ka Catalytic Crude to Chemicals (CC2C TM). ) ʻenehana.
Hiki i ka ʻenehana CC2C TM ke hoʻonui nui i ka maikaʻi a me ka hua o ka hana kemika, e hoʻololi ana ma mua o 60% o ka barela o ka aila ʻaila i loko o nā kemika.
I ʻOkakopa 2020, ua hoʻolaha ʻo SABIC e loiloi hou ana a hoʻonui paha i kāna ʻike no ka papahana ʻaila-a-kemika (COTC) ma Yanbu, Saudi Arabia me ka hoʻohui ʻana o nā ʻenehana i kēia manawa.
Ua haʻi aku ka hui i ka Saudi stock exchange e hoʻolālā ana e hoʻonui i kēia papahana me Saudi Aramco "e hoʻokomo i nā papahana hoʻomohala i kēia manawa o ka holomua ʻana i nā ʻenehana kemika a me ka hoʻohui ʻana i nā mea hana" i mea e hoʻonui ai i ka waiwai i mua o ka mākeke o kēia manawa. pilikia.Ma mua o kēia makahiki, ua kūʻai ʻo Aramco i kahi stake 70% ma SABIC a mai ia manawa ua hōʻemi nui nā hui ʻelua i kāna mau hoʻolālā capex ma muli o ka hopena COVID-19.
Ua manaʻo mua ʻia ka papahana Yanbu COTC i ʻekolu mau makahiki i hala aku nei e hana i ka 400,000 barela i kēlā me kēia lā o ka ʻaila aila meaʻai i loko o 9 miliona tons o ka makahiki o nā huahana kemika a me ka aila kumu, me ka hoʻomaka ʻana i manaʻo ʻia ma 2025. Hiki ke hoʻololi i kēlā lā i mua o kēia. ka hoʻihoʻi hou ʻana, a ʻo ke kumukūʻai o ka papahana i manaʻo ʻia he $20 biliona e manaʻo ʻia e iho i lalo i ka haʻalele ʻana o ka papahana i ke kūkulu ʻana i kahi mea kanu hou a hilinaʻi i nā hale e kū nei ma kahi kokoke.
ʻO ka Reliance Industries e hoʻokomo i loko o India COTC Complex
Hoʻolālā ʻo Reliance Industries e hoʻolilo i $ 9.8 biliona i loko o kahi paʻakikī-ʻaila-a-kemika (COTC) ma ka pūnaewele ʻo Jamnagar ma India, e like me ka hōʻike ʻana o Chemical Week i Nowemapa 2019.
Ke manaʻo nei ʻo Reliance e kūkulu i nā ʻāpana COTC me kahi pahu pahu mahu multi-feed a me multi-zone catalytic cracking (MCC).Hoʻolālā pū ka hui e hoʻololi i ka ʻāpana fluid catalytic cracking (FCC) i kahi FCC (HSFCC) a i ʻole Petro FCC unit, e hoʻonui i ka ethylene a me ka propylene hua.
ʻO ka paʻakikī MCC/HSFCC e hui pū ʻia no 8.5 miliona metric tons/makahiki (Mln mt/yr) o ka ethylene a me propylene, a me ka nui o ka hiki ke unuhi no 3.5 Mln mt/yr o benzene, toluene, a me xylenes.Loaʻa iā ia ka mana hui no 4.0 Mln mt/yr o para-xylene (p-xylene) a me ortho-xylene.Hiki i ka pahū mahu hui ke mana no 4.1 Mln mt/yr o ka ethylene a me propylene, a e hānai i nā C4 maʻemaʻe i kahi mea kanu hoʻoheheʻe butadiene 700kt/makahiki.
