propylene oxide yog coj los ua ib qho nruab nrab hauv kev tsim khoom ntawm polyurethane, antifreeze thiab lwm yam khoom siv tshuaj. Apipeline density meteryog kev koom ua ke rau hauv cov kab ntau lawm ntawm propylene oxide manufacturing chaw - Propylene Oxide Plant rau kev tswj cov tshuaj tiv thaiv, uas yog ib qho tseem ceeb reactant.Hydrogen peroxide (H₂O₂)reacts nrog propylene nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim propylene oxide.
Cov tshuaj tiv thaiv, cov khoom zoo thiab kev ua haujlwm tag nrho tuaj yeem hloov kho los ntawm aHydrogen peroxide concentration meterntawm ntau theem ntawm kev tsim khoom. Cov tshuaj tiv thaiv tseem ceeb so ntawm epoxidation cov tshuaj tiv thaiv, qhov twg propylene reacts nrog hydrogen peroxide (H₂O₂) nyob rau hauv lub xub ntiag ntawm ib tug catalyst (feem ntau yog ib tug tungstate los yog molybdate-raws li catalyst) tsim propylene oxide (C₃H₆O) thiab dej (H₂O).
Kev ntsuas cov ntsiab lus ntawm kev tsim cov propylene Oxide
Cov ntsiab lus ntsuas tseem ceeb suav nrog cov khoom siv raw inlet, cov hlab ntsha tawg, kev sib cais thiab rov qab theem, thiab lwm yam. Hydrogen peroxide feed inlet yog qhov tsim nyog los xyuas kom meej cov ntsiab lus xav tau. Feem ntau, hydrogen peroxide yog khaws cia rau hauv cov ntaub ntawv concentrated, thiab nws yuav tsum tau diluted ua ntej ua ntxiv los yog tshuaj tiv thaiv nrog lwm yam tshuaj.
Tom qab ntawd tuaj rau ntawm cov hlab ntsha los yog cov reactor. Qhov no yog lwm qhov ntsuas ntawmKev ntsuas qhov concentration ntawm hydrogen peroxidekom cov tshuaj tiv thaiv tau nce raws li qhov xav tau. Ib inline txheej txheem ceev meterlos yog lwm yam sensor muaj peev xwm ntsia tau rau ntawm qhov hluav taws xob reactor los saib xyuas lub sijhawm tiag tiag ntawm hydrogen peroxide raws li nws cuam tshuam nrog propylene. Cov ntsedensity meter onlineenables dynamic hloov ntawm hydrogen peroxide ua tau rau nws tas li saib xyuas. Yog hais tias qhov concentration poob sai dhau los yog cov tshuaj tiv thaiv tsis mus tom ntej raws li qhov xav tau, nws yuav tsum tau kho qhov ntws ntawm hydrogen peroxide rau hauv lub reactor.
Tom qab cov tshuaj tiv thaiv cuam tshuam nrog kev sib cais thiab ua kom huv ntawm propylene oxide thiab cov khoom lag luam, xws li dej thiab tsis muaj tshuaj hydrogen peroxide. Piv txwv li, qib siab hydrogen peroxide ua rau muaj kev pheej hmoo rau ib puag ncig kev ruaj ntseg thiab tib neeg txoj kev nyab xeeb. Kev ntsuas concentration kom raug ua kom muaj nuj nqis thiab kev ua haujlwm ruaj khov ua tau raws li cov cai thiab cov cai.
Kev ntsuas kev txawj ntse ntawm cov ntsiab lus tseem ceeb hauv cov txheej txheem yuav pab tau ntau yam hauv kev tsim kho kom zoo. Kev siv cov thev naus laus zis zoo lionline densitometers, spectrophotometers, thiab titration txoj kev tso cai rau kev saib xyuas lub sijhawm tiag tiag, kev ntsuas qhov tseeb, thiab kev tswj cov txheej txheem zoo dua, thaum kawg ua rau cov txiaj ntsig siab dua thiab kev ua haujlwm zoo dua.
Thov hu rauLonnmeterengineers rau ntau kev sab laj txog lubhauv kab Hydrogen peroxide concentration meter los xyuas seb nws puas tuaj yeem siv rau koj cov kab ntau lawm lossis cov nroj tsuag. Thov daim ntawv tso cai pub dawb tam sim no thiab tau txais tus nqi ntawm qhov ntsuas qhov ceev.
