Kutengera zochitika zazikulu zomwe zikuchitika pamsika wa gasi wosungunuka mu 2023, pali zinthu ziwiri zomwe zimakhudza mwachindunji zofunikira za kupezeka ndi kufunikira: choyamba, ngozi yachitetezo cha malo odyera a Ningxia; Ii. Mafuta a alkylate amalipidwa ndi msonkho wogwiritsidwa ntchito. Zochitika ziwiri zazikuluzikuluzi zimakhudza msika wa Civil ndi olefin carbon 4 motsatana.

Ngozi zachitetezo zimakhudza mwachindunji kufunika kwa gasi wamba, kutsata malamulo kumunda, kusatsata sikukwaniritsa zofunikira za chiletso, kumagulu okhazikika kuti apereke msika; Komabe, zimakhalanso ndi vuto pakugwiritsa ntchito gasi wamba.

Pakhala pali malipoti ambiri ndikuwunika zakusintha kwakukulu pamsika komwe kumachitika chifukwa cha msonkho wamafuta a alkylate komanso kukwera kwakukulu kwamitengo. Miyezi isanu yapita kuyambira kukhazikitsidwa kwa ndondomekoyi, ndipo tiwona momwe zimakhudzira msika wa carbon four kudzera mu data.

Kupyolera mu kusintha kwa kufunikira kwa C4 ya olefin mu zipangizo za alkylation, zikhoza kuwoneka kuti zofunazo zimakhala zokhazikika m'miyezi imodzi kapena iwiri isanayambe ndondomeko yoyenera. Tchuthi chaching'ono mu Meyi chinali nthawi yapamwamba kwambiri yofuna mafuta, yomwe imayenera kukhala yokwera kwambiri pomanga zida za alkylation, koma msonkho wogwiritsidwa ntchito unkaperekedwa kumapeto kwapakati komanso mochedwa, ndipo mabizinesi ena adachepetsa katunduyo kapena kuyimitsa ntchito. kupeŵa zoopsa, zomwe zimapangitsa kuchepa kwa kuchuluka kwa magwiridwe antchito ndi kufunikira, komanso kuchuluka kwa kugwiritsa ntchito mphamvu ya alkylation kudatsika pafupifupi 10 peresenti m'kanthawi kochepa. Pambuyo pafupifupi theka la mwezi wachisokonezo, mafuta a alkylated ndi olefin C4 msika adapezanso malo atsopano: mtengo wa olefin C4 wachepetsedwa kwambiri.

Mu May, mtengo wa olefin carbon 4 waku China unagwa 11.76%, unapitirira kutsika 8.84% mu June, ndipo unayambiranso mu August; Phindu la Alkylation linali lokwera kwambiri pakugwa kwa gasi, koma phindu linatsika pang'onopang'ono ndikuyamba kwa msonkho m'nthawi yamtsogolo, ndikulowa mu Ogasiti, kutayika kwanthawi yayitali. Kubwezeredwa kwa carbon 4 yaiwisi kumachitika chifukwa chosungirako zida zotsika mtengo za alkylation. Kutsikiraku kumaphatikizapo mayunitsi a alkylation komanso ena. Kukhudzidwa ndi mbali yoletsa ndondomeko, mtengo wa carbon four wa olefin wagwera pansi, osati phindu la chipangizo cha alkylation, komanso gawo la chipangizo cha olefin isomerization, mabizinesi ena oimitsidwa ayambiranso ntchito kapena anayambiranso mapulani a ntchito, ndipo mbali yofunikila yapita patsogolo pang’onopang’ono.

Msika wa olefin carbon 4 sunabwerere ku bata chifukwa cha kukhazikika kwatsopano, ndipo kuyendera nthawi ndi nthawi kudzakhudzanso zomwe zikuchitika mu magawo, ndipo tsogolo la olefin carbon 4 lidzafunafunabe chitukuko chatsopano mu chipwirikiti.
