Propylene oxide inotorwa seyepakati mukugadzira polyurethane, antifreeze uye mamwe makemikari emaindasitiri. Apipeline density mitainosanganiswa mumutsara wekugadzira wepropylene oxide yekugadzira nzvimbo -- Propylene Oxide Chirimwa chekutonga chaiko pamusoro pemakemikari kuita, mune imwe yakakosha reactant.hydrogen peroxide (H₂O₂)inopindirana nepropylene pamberi pechinhu chinokonzeresa kuumba propylene oxide.
Rection rate, mhando yechigadzirwa uye kunyatsoshanda zvese zvinogona kugadziriswa kuburikidza neahydrogen peroxide concentration mitapamatanho akasiyana-siyana ekugadzirwa. Mhedzisiro huru inogara pane epoxidation reaction, apo propylene inopindirana nehydrogen peroxide (H₂O₂) pamberi pechinokonzera (kazhinji tungstate kana molybdate-based catalyst) kugadzira propylene oxide (C₃H₆O) uye mvura (H₂O).
Mapoinzi ekuyera eKugadzirwa kwePropylene Oxide
Yakakosha yekuyera mapoinzi anosanganisira mbishi zvinhu inlet, reaction mudziyo, kupatsanurwa uye kudzoreredza chikamu, etc. Hydrogen peroxide feed inlet inzvimbo inodiwa kuve nechokwadi chinodiwa. Kazhinji, hydrogen peroxide inochengetwa mune yakanyungudutswa fomu, uye inoda kuderedzwa isati yaenderera mberi nekugadzirisa kana kuita nemamwe makemikari.
Wobva wauya kune reaction mudziyo kana reactor. Iyi ndiyo imwe nzvimbo yekuyera yehydrogen peroxide concentration kuyerwakuitira kuti mhinduro ifambire mberi sezvaitarisirwa. An inline process density mitakana imwe sensor inokwanisa kuisirwa pane reactor yekubuda kuti itarise chaiyo-nguva yekumisikidzwa kwehydrogen peroxide painopindirana nepropylene. Vakangwaradensity mita onlineinogonesa gadziriso inochinja yehydrogen peroxide inogoneka yekuenderera kwayo kutarisa. Kana iyo yekumisikidza ikadonha nekukurumidza kana kuita kukasaenda kumberi sezvanga zvichitarisirwa, zvinodikanwa kugadzirisa kuyerera kwehydrogen peroxide mureactor.
Post-reaction inosanganisira kupatsanurwa uye kucheneswa kwepropylene oxide uye ne-zvigadzirwa, zvakadai semvura uye isina kugadziriswa hydrogen peroxide. Semuenzaniso, yakakwirira-level hydrogen peroxide inoisa njodzi kune kuchengetedzwa kwezvakatipoteredza uye kuchengetedzwa kwevanhu. Kuyera kwakaringana kuyerwa kunoita kuti quantification uye inogoneka kugadzirisa kugoneke kutevedzera mitemo nemirau.
Hungwaru hwekuyera masisitimu panzvimbo dzakakosha mukuita kunobatsira zvakanyanya mukugadzirisa kugadzirwa. Kushandisa tekinoroji yepamusoro sengeonline densitometers, spectrophotometers, uye titration nzira dzinobvumira kutarisisa-chaiyo-nguva, kuyera kwakaringana kuyerwa, uye zvirinani kudzora maitiro, zvinozotungamira kune yakakwira goho uye mashandiro akachengeteka.
Please contactLonnmetermainjiniya kuti uwane mamwe kubvunza nezveinline hydrogen peroxide concentration mita kuti uone kana inogona kuiswa kune yako yekugadzira mutsara kana zvidyarwa. Kumbira mutengo wemahara izvozvi uye uwane mutengo we density mita.
