[Chitsogozo] : Chakumapeto kwa June, kutsekedwa kosayembekezereka kwa zipangizo zamsika za propylene kunachitika chimodzi pambuyo pa chimzake, chomwe chinali chokomera mbali yopereka chithandizo, pamene chidwi cha zinthu zotsika mtengo chinakwera, ndipo mtengo wamsika unasiya kugwa, kuyambira July 14, anthu ambiri. msika wa Shandong propylene mtengo unali 6480-6500 yuan/ton, ndipo msika wa East China unali 6350-6350 yuan/ton.

Pakuzungulira uku, msika wapakhomo wa propylene wasiya kugwa ndikuchira, ndipo zinthu zomwe zimathandizira kubwezeredwa kwa msika ndizofunika kwambiri pakuperekera komanso kufunikira. Macro, mitengo yamafuta padziko lonse lapansi idakwera, zinthu zazikuluzikulu zabwino ndi izi: kuchuluka kwa inflation ku United States ndikwabwino, Federal Reserve kupitiliza kukweza chiwongola dzanja chachepa, ndipo kuchepetsedwa kwakupanga kwa Saudi Arabia kunabweretsa kupitiliza kwa mlengalenga wabwino, msika. Nthawi yomweyo, kuyimitsidwa kwakanthawi kwa zida za Qingdao Jinneng, Wangtong, ndi Zhenghe propylene m'derali, pomwe zida zopangira magalimoto zoyambilira sizinayambitsidwenso, ndipo zoperekera zikuyang'anizana ndi msika ndi chithandizo china, komanso kuchuluka kwapadziko lonse kwa PDH. ndi 69.79% monga masiku 14, omwe ndi 0.2% otsika kusiyana ndi kuzungulira kwapita. Ndi kugwa kwa zomangamanga za propylene, kuchuluka kwa mabizinesi opanga ma propylene sikuli kokulirapo, mtengo wopereka umakwezedwa pang'onopang'ono, chidwi chogula chapansi pamadzi chimakhala bwino, ndipo msika wonse wamalonda uli bwino.

Pakuzungulira uku, njira zitatu za propylene zimasakanizidwa, ndipo phindu la propane dehydrogenation ku propylene likuwonekera kwambiri. Kumbali imodzi, mtengo wamtengo wapatali wa propane ukupitirirabe kugwa panthawiyi, ndipo kumbali ina, mtengo wa propylene monomer ndi wamphamvu, zomwe zimapereka mphamvu zowonjezera phindu. Phindu la naphtha ndi methanol ku propylene linapitirirabe kuchepa, ndipo phindu la methanol kupita ku propylene linatsika kwambiri, lomwe makamaka linakhudzidwa ndi kukwera kwa mtengo wa methanol yaiwisi, yomwe inalepheretsa phindu. Naphtha to propylene process phindu limatsika kuyambira sabata yatha, chomwe chimalimbikitsa kwambiri ndi mtengo wa naphtha wocheperako m'mwamba, komanso pakukwera kwa phindu komwe kumayambitsa, akuyembekezeka kutsika kwakanthawi kochepa kwa phindu la propylene, mochedwa tcherani khutu kumsika. mtengo wa zipangizo.

M'kanthawi kochepa, pa gawo loperekera, ndikuyambiranso kwa zida za PDH ku Shandong, katundu wa zomwe angoyika kumene mukupanga koyambirira akuwonjezeka pang'onopang'ono, ndipo ma propylene akuyembekezeka kuwonjezeka, koma kuyimitsidwa kwakanthawi zipangizo fakitale munthu ku Shandong adzapereka mphamvu zina kumsika. Mbali yofunidwa, panthawiyi, msika wa polypropylene umakhala wolimba kwambiri, phindu la ufa liri bwino, mafakitale akumunsi amangofunika kugula makamaka, pamene sabata yamawa PO, fakitale ya acrylonitrile ikuyembekezeka kuyambiranso, zikuyembekezeka kuti propylene yanthawi yochepa. msika ukhoza kukhala ndi kukwera pang'ono, koma malo okwerawo ndi ochepa, tsatirani mosamala kuyambiranso ndi kutumiza kwa opanga propylene.

Mbali yofunidwa, msika wa polypropylene ukuyenda mozungulira, kufunikira kwa mbali yofunikira ndi yolimba, mtengo wa propylene wokhazikika udatsika, kufalikira pakati pa propylene ndi PP kukukulirakulira, phindu la fakitale lakutsika pang'onopang'ono linakula, chidwi chogula chinayambanso pang'onopang'ono. mmwamba, zidapangitsa kuti mabizinesi a propylene atumizidwe bwino, malo owerengera pang'onopang'ono mpaka otsika, kuthandizira mitengo ya propylene kukwera.
