Propylene oxide imagwiritsidwa ntchito popanga polyurethane, antifreeze ndi mankhwala ena a m'mafakitale.mita yoyezera kuchuluka kwa mapaipiimaphatikizidwa mu mzere wopanga wa propylene oxide manufacturing facility -- Propylene Oxide Plant kuti ilamulire bwino momwe mankhwala amachitira, momwe chinthu chimodzi chofunikira chimagwirira ntchito.hydrogen peroxide (H₂O₂)Amachitapo kanthu ndi propylene pamaso pa chothandizira kupanga propylene oxide.
Chiŵerengero cha zochita, mtundu wa malonda ndi magwiridwe antchito onse zitha kusinthidwa kudzera muchoyezera kuchuluka kwa hydrogen peroxidepa magawo osiyanasiyana opanga. Yankho lalikulu limadalira pa epoxidation reaction, pomwe propylene imayankhira ndi hydrogen peroxide (H₂O₂) pamaso pa catalyst (nthawi zambiri chothandizira cha tungstate kapena molybdate) kuti ipange propylene oxide (C₃H₆O) ndi madzi (H₂O).
Kuyeza kwa Propylene Oxide mu Kupanga
Malo ofunikira kwambiri oyezera ndi monga kulowa kwa zinthu zopangira, chotengera cha reaction, gawo lolekanitsa ndi kuchira, ndi zina zotero. Kulowa kwa hydrogen peroxide feed ndi malo ofunikira kuti zitsimikizire zofunikira. Kawirikawiri, hydrogen peroxide imasungidwa mu mawonekedwe okhuthala, ndipo imafunika kuchepetsedwa madzi isanakonzedwenso kapena kuyankhidwa ndi mankhwala ena.
Kenako bwerani ku chotengera cha reaction kapena reactor. Iyi ndi malo ena oyezera aMuyeso wa kuchuluka kwa hydrogen peroxidekotero kuti zomwe zikuchitika zikupita patsogolo monga momwe zikuyembekezeredwa. mita yoyezera kuchuluka kwa njira yolumikiziranakapena sensa ina imatha kuyikidwa pamalo otulutsira mpweya kuti iwunikire kuchuluka kwa hydrogen peroxide nthawi yeniyeni pamene ikuchitapo kanthu ndi propylene.mita yochulukitsira anthu pa intanetizimathandiza kusintha kwa hydrogen peroxide kuti iwonekere mosalekeza. Ngati kuchuluka kwa hydrogen peroxide kumatsika mofulumira kwambiri kapena ngati zinthu sizikuyenda bwino monga momwe zimayembekezeredwa, ndikofunikira kusintha kayendedwe ka hydrogen peroxide mu reactor.
Pambuyo pa kuchitapo kanthu kumaphatikizapo kulekanitsa ndi kuyeretsa propylene oxide ndi zinthu zina, monga madzi ndi hydrogen peroxide yosakhudzidwa. Mwachitsanzo, hydrogen peroxide yapamwamba kwambiri imabweretsa zoopsa ku chilengedwe komanso chitetezo cha anthu. Kuyeza bwino kuchuluka kwa madzi kumapangitsa kuti kuyeza ndi kukonza zinthu kukhale kotheka kuti zitsatire malamulo ndi malangizo.
Njira zoyezera zanzeru panthawi yofunika kwambiri zimathandiza kwambiri pakupanga bwino. Kugwiritsa ntchito ukadaulo wapamwamba mongazoyezera kuchuluka kwa shuga pa intaneti, ma spectrophotometer, ndi njira zoyezera titration zimathandiza kuyang'anira nthawi yeniyeni, kuyeza molondola kuchuluka kwa zinthu, komanso kuwongolera bwino njira, zomwe pamapeto pake zimapangitsa kuti pakhale zokolola zambiri komanso ntchito zotetezeka.
Chonde lemberaniLonnmetermainjiniya kuti mumve zambiri zokhudzamotsatana choyezera kuchuluka kwa hydrogen peroxide kuti mudziwe ngati ingagwiritsidwe ntchito pamakina anu opangira kapena mafakitale. Pemphani mtengo waulere tsopano ndipo pezani mtengo wa mita yoyezera kuchuluka kwa mafuta.
