【Lead】 Lub lim tiam no, kev lag luam tag nrho ntawm cov propylene kev lag luam saw tau zoo dua me ntsis. Cov khoom lag luam feem ntau tseem xoob, thaum qhov kev ua haujlwm dav dav ntawm cov khoom lag luam qis tau nce. Ua ke nrog kev txhim kho cov txiaj ntsig ntawm qee cov khoom lag luam hauv qab, cov nroj tsuag hauv qab qhov kev lees txais ntawm cov nqi propylene tau nce, ntxiv dag zog rau kev txhawb nqa rau propylene xav tau thiab muab qee yam kev txhawb nqa rau kev lag luam propylene.
Lub lim tiam no, cov nqi lag luam propylene hauv tsev tau rov qab los tom qab ntaus hauv qab, nrog kev ua lag luam thiab kev xav tau kev ua si yog qhov tseem ceeb. Tus nqi nruab nrab txhua lub lim tiam ntawm propylene hauv Shandong lub lim tiam no yog 5,738 yuan / ton, ib hlis-rau-hli poob ntawm 0.95%; tus nqi nruab nrab txhua lub lim tiam hauv East Tuam Tshoj yog 5,855 yuan / ton, ib hlis-rau-hli poob ntawm 1.01%.
Lub lim tiam no, tus nqi sib txawv ntawm cov saw hlau ua lag luam tau sib xyaw nrog cov kev hloov pauv tag nrho. Tus nqi ntawm cov ntaub ntawv tseem ceeb tau pom qhov sib txawv nce thiab nqis nrog me me volatility, muaj kev cuam tshuam rau cov nqi propylene. Tus nqi nruab nrab ntawm propylene poob me ntsis lub hli-rau-hli thiab rebounded tom qab ntaus hauv qab. Cov nqi ntawm cov khoom siv qis qis kuj muaj ob qho tib si nce thiab nqis: ntawm lawv, tus nqi ntawm propylene oxide tau nce siab heev, thaum tus nqi ntawm acrylic acid poob kuj ceeb heev. Feem ntau cov nroj tsuag downstream tau ntxiv cov khoom lag luam ntawm tus nqi qis.
Kev lag luam kev khiav hauj lwm tus nqi nce nrog cov khoom siv xoob.
Lub lim tiam no, propylene kev khiav hauj lwm tus nqi mus txog 79.57%, nce ntawm 0.97 feem pua cov ntsiab lus ntawm lub lim tiam dhau los. Thaum lub asthiv, PDH chav nyob ntawm Haiwei thiab Juzhengyuan, nrog rau MTO chav tsev ntawm Hengtong, tau txais kev saib xyuas, uas muaj kev txhawb nqa rau kev lag luam. Kev lag luam propylene khaws cia cov khoom siv xoob xoob, thiab qee qhov chaw kho lawv cov haujlwm ua haujlwm, ua rau muaj kev nce me ntsis hauv kev lag luam kev khiav hauj lwm lub lim tiam no.
Downstream Comprehensive Operating Rate Index nce, Propylene Demand txhim kho
Lub lim tiam no, qhov ntsuas kev ua haujlwm dav dav ntawm propylene downstream industries sawv ntawm 66.31%, nce ntawm 0.45 feem pua ntawm cov ntsiab lus ntawm lub lim tiam dhau los. Ntawm lawv, kev khiav hauj lwm tus nqi ntawm PP hmoov thiab acrylonitrile tau nce kuj tseem ceeb, thaum cov phenol-ketone thiab acrylic acid poob qis heev. Lub lim tiam no, tag nrho cov kev khiav hauj lwm qis qis qis tau nce ntxiv, ua rau qhov kev thov nruj rau propylene los ntawm cov nroj tsuag hauv qab. Tsis tas li ntawd, nrog cov nqi propylene nyob rau theem qis thiab cov nyiaj tau los ntawm qee cov khoom lag luam hauv qab tau txhim kho, cov khoom lag luam qis qis rau propylene tau nce, muab kev txhawb nqa me ntsis rau kev thov propylene.
Cov txiaj ntsig ntawm cov khoom lag luam hauv qab txhim kho me ntsis, txhim kho kev lees txais ntawm cov nqi propylene
Lub lim tiam no, cov txiaj ntsig ntawm propylene downstream khoom tau sib xyaw. Nrog rau propylene tus nqi nruab nrab ntawm tus nqi qis, tus nqi siab ntawm qee cov khoom lag luam downstream eased. Tshwj xeeb, PP hmoov hloov los ntawm cov nyiaj tau los poob rau lub lim tiam no, thaum cov txiaj ntsig ntawm PO (propylene oxide) tau nce ntxiv. Qhov poob npoo ntawm n-butanol nthuav dav, thaum ntawm 2-ethylhexanol, acrylonitrile, thiab phenol-ketone nqaim. Tsis tas li ntawd, cov txiaj ntsig ntawm acrylic acid thiab propylene-based ECH tsis kam. Zuag qhia tag nrho, cov txiaj ntsig ntawm cov khoom lag luam hauv qab tau txhim kho me ntsis tab sis nruab nrab, uas tau txhim kho lawv qhov kev lees paub ntawm cov nqi propylene.
