[Phau Ntawv Qhia]: Thaum kawg ntawm Lub Rau Hli, kev kaw tsis tau xav txog ntawm cov khoom siv hauv kev lag luam propylene tau tshwm sim ib qho tom qab ib qho, uas tau txais txiaj ntsig zoo rau sab kev muab khoom, thaum kev txaus siab ntawm cov khoom lag luam downstream tau nce siab, thiab tus nqi hauv kev lag luam tsis poob qis, txij li Lub Xya Hli 14, kev lag luam tseem ceeb ntawm Shandong propylene kev lag luam tus nqi yog 6480-6500 yuan / ton, thiab kev lag luam tseem ceeb ntawm East China kev lag luam yog 6350-6350 yuan / ton.

Hauv lub voj voog no, kev ua lag luam propylene hauv tsev tau tso tseg thiab rov zoo, thiab cov yam ntxwv txhawb nqa kev rov qab los ntawm kev ua lag luam feem ntau yog nyob rau hauv cov hauv paus ntawm kev muab khoom thiab kev thov. Macro, cov nqi roj thoob ntiaj teb tau nce, cov yam ntxwv zoo tseem ceeb yog: cov ntaub ntawv nce nqi ntawm Tebchaws Meskas zoo, Federal Reserve txuas ntxiv nce tus nqi paj laum siab tsis muaj zog, thiab Saudi Arabia qhov kev txiav ntau ntxiv tau coj mus rau qhov txuas ntxiv ntawm qhov chaw zoo, rau kev ua lag luam. Tib lub sijhawm, qhov chaw nres tsheb ib ntus ntawm Qingdao Jinneng, Wangtong, thiab Zhenghe propylene cov khoom siv hauv cheeb tsam, thaum lub cuab yeej saib xyuas chaw nres tsheb thaum ntxov tsis tau rov pib dua, thiab cov khoom siv tau ntsib kev ua lag luam nrog qee qhov kev txhawb nqa, thiab tus nqi tsim khoom PDH hauv tebchaws yog 69.79% raws li 14 hnub, uas yog 0.2% qis dua lub voj voog dhau los. Nrog rau kev poob ntawm kev tsim kho propylene, cov khoom muag ntawm cov tuam txhab tsim khoom propylene tsis siab tag nrho, tus nqi muab khoom maj mam thawb mus, kev yuav khoom hauv qab zoo dua, thiab qhov chaw ua lag luam tag nrho yog OK.

Hauv lub voj voog no, peb txoj kev ua propylene sib xyaw, thiab qhov txiaj ntsig ntawm propane dehydrogenation rau propylene yog qhov pom tseeb dua. Ntawm ib sab tes, tus nqi ntawm propane tseem poob qis ntawm theem no, thiab ntawm qhov tod tes, tus nqi ntawm propylene monomer muaj zog, uas muab qee qhov kev txhawb nqa rau qhov sib txawv ntawm cov txiaj ntsig. Cov txiaj ntsig ntawm naphtha thiab methanol rau propylene txuas ntxiv poob qis, thiab cov txiaj ntsig ntawm methanol rau propylene txheej txheem poob qis heev, uas feem ntau cuam tshuam los ntawm tus nqi nce ntawm cov khoom siv raw methanol, uas cuam tshuam cov txiaj ntsig. Naphtha rau propylene txheej txheem cov txiaj ntsig feem ntau poob qis los ntawm lub lim tiam dhau los, qhov tseem ceeb cuam tshuam yog tus nqi naphtha nqaim mus rau sab saud, tab sis kuj ntawm cov txiaj ntsig tsav tsheb rub ua rau, xav tias yuav luv luv propylene cov txiaj ntsig volatility sib txawv, lig them ze rau tus nqi lag luam ntawm cov khoom siv raw.

Nyob rau lub sijhawm luv luv, ntawm sab khoom, nrog rau kev rov pib dua ntawm PDH cov khoom siv hauv Shandong, lub nra ntawm cov khoom tshiab tso rau hauv kev tsim khoom thaum ntxov maj mam nce, thiab cov khoom siv propylene tam sim no xav tias yuav nce ntxiv, tab sis qhov chaw nres tsheb ib ntus ntawm cov khoom siv hauv Hoobkas hauv Shandong yuav muab qee qhov kev txhawb nqa rau kev ua lag luam. Sab kev thov, ntawm theem no, kev ua lag luam polypropylene feem ntau yog qhov sib txawv, cov nyiaj tau los ntawm hmoov yog OK, cov chaw tsim khoom hauv qab tsuas yog xav tau yuav feem ntau, thaum lub lim tiam tom ntej PO, acrylonitrile Hoobkas xav tias yuav rov pib dua, nws xav tias kev ua lag luam propylene luv luv yuav muaj qhov nce me me, tab sis qhov chaw nce yog txwv, ua raws li qhov rov pib dua thiab xa khoom ntawm cov chaw tsim khoom propylene.

Sab kev thov, qhov sib txawv ntawm kev ua lag luam polypropylene hauv lub voj voog, kev txhawb nqa sab kev thov muaj zog, tus nqi propylene ua ntej-stack poob qis, qhov sib txawv ntawm propylene thiab PP nthuav dav, cov nyiaj tau los ntawm lub Hoobkas maj mam nce, kev txaus siab yuav khoom kuj maj mam nce, ua rau kev xa khoom ntawm cov tuam txhab propylene du, qhov chaw muag khoom maj mam mus rau qis, txhawb nqa tus nqi propylene nce.
