Pambuyo poti benzene/hydrobenzene yoyera yatsika kufika pa yuan 6000, chifukwa cha kufewetsa kwa mfundo za dziko, malingaliro a msika adasintha pang'ono, amalonda ena ndi kugula zinthu zotsika mtengo, kuchuluka kwa ma transaction a benzene/hydrobenzene, adakweza kukwera kwa mitengo, kuyambira pa June 16, mtengo wa benzene yamafuta a Shandong unali pafupifupi yuan 6220/tani, kuwonjezeka kwa yuan 80-140/tani. Anakhazikitsa maziko a rebound ya hydrobenzene ya sabata ino.

Pakadali pano, msika ukuyang'ana kwambiri kuwonjezeka kwa kuchuluka kwa mphamvu ya styrene yomwe imagwiritsidwa ntchito, kuchepa kwa kuchuluka kwa phenol komwe kumagwiritsidwa ntchito komanso kuwonjezeka kwa zinthu zopangidwa ndi benzene.

1, kugwiritsa ntchito mphamvu zazikulu za styrene pansi pake kukuyembekezeka kuwonjezeka

Gawo loyamba la fakitale ya styrene yomwe yayimitsidwa ikukonzekera kuyambiranso, limodzi ndi Zhejiang Petrochemical, zida zokwana matani 600,000 zayikidwa nthawi ya 15 koloko pa June 16, kuchokera ku deta ya kupanga ndi kugwiritsa ntchito mphamvu ya styrene ku China ikuyembekezeka kusintha kuchuluka kwa zinthu. Kugwiritsa ntchito mphamvu ya styrene kudzawonjezera kufunikira kwa benzene yoyera, kudzawonjezera kugwiritsa ntchito benzene yoyera, koma pambuyo pa kuwonjezeka kwa kuchuluka kwa ntchito ya styrene, ndikofunikirabe kulabadira kufanana kwa styrene yotsika, ngati styrene yotsika ndi yovuta kukwaniritsa kusintha kogwirizana, styrene ikukumana ndi vuto la kuchepetsa kupereka ndi kufunikira, pambuyo pake, styrene pang'onopang'ono idzalowa mu nyengo yotentha kwambiri.

2, kuchepa kwa phenol ketone kukupitilizabe kuchepa

Posachedwapa makampani a phenol ketone omwe ali pansi pa nyanja anayamba pa mlingo wa 69%, mwezi uliwonse -1%. Pakati pawo, panthawi yotseka ndi kukonza mayunitsi a Jiangsu Ruiheng, Shanghai Sisar ndi Gaoqiao Petrochemical phenol ketone, mayunitsi a phenol ketone oyenga bwino a Shenghong anali ndi ntchito yoipa, kotero kuchuluka kwa phenol ketone komwe kunapitilira kuchepa, kuchepetsa kugwiritsa ntchito benzene yoyera, ndikupanga mayankho oipa pa benzene/hydrobenzene yoyera.

3, malonda ochokera ku China a benzene akuyembekezeka kuwonjezeka

Pamene nthawi yosungiramo zinthu kunja kwa dziko yatha, ndipo mphamvu ya octane yachepa, benzene yoyera ya ku Asia iyenera kulowa ku China kuti idye, ndipo akuyembekezeka kuti malonda ochokera kunja kwa benzene yoyera ya m'dzikolo adzawonjezeka, zomwe zingapangitse kuti pakhale kuwonjezeka kwa kuchuluka kwa benzene yoyera ya m'dzikolo, kuchokera ku matani 200,000 mpaka matani 300,000 a sikelo.

Kuphatikiza apo, Hainan Refining ndi Chemical yatsopano matani 2.6 miliyoni a chakudya chokonzanso, CNOOC Huizhou yatsopano matani 1.3 miliyoni a chokonzanso chotulutsa cha aromatics ndi disproportionation akuyembekezeka kuyikidwa mu chakudya pambuyo pake, kupezeka kwa benzene yoyera m'nyumba kudakwera.

Mu kanthawi kochepa, kuphatikizapo kubwezeretsanso kopanda kanthu kumapeto kwa mwezi, akuyembekezeka kuti malo ogulitsira benzene/hydrobenzene yoyera atha kukwera, ndipo mtengo wa hydrobenzene ukhoza kukhazikika ndikubwerera, koma kutalika ndi mphamvu ya kubwereranso ndizochepa, chifukwa msika ukadali pa nkhani zoipa, ndipo mzere wapakati ndi wautali umaperekedwa ndi malingaliro opanda pake.
