I-Propylene oxide ithathwa njengendawo ephakathi ekwenzeni i-polyurethane, i-antifreeze namanye amakhemikhali ezimboni. Aimitha yokuminyana kwepayipiihlanganiswe emgqeni wokukhiqiza wesikhungo sokukhiqiza i-propylene oxide -- I-Propylene Oxide Plant yokulawula okunembile kokusabela kwamakhemikhali, lapho i-reactant eyodwa ebalulekile.i-hydrogen peroxide (H₂O₂)ihlangana ne-propylene phambi kwe-catalyst yakhe i-propylene oxide.
Izinga lokusabela, ikhwalithi yomkhiqizo kanye nokusebenza kahle kukonke konke kungalungiswa ngokusebenzisa aimitha yokuhlushwa ye-hydrogen peroxideezigabeni ezehlukene zokukhiqiza. Ukusabela okuyinhloko kuncike ekuphenduleni kwe-epoxidation, lapho i-propylene ihlangana ne-hydrogen peroxide (H₂O₂) phambi kwe-catalyst (imvamisa i-tungstate noma i-molybdate-based catalyst) yakhe i-propylene oxide (C₃H₆O) namanzi (H₃O).
Amaphuzu Wokulinganisa Ekukhiqizeni I-Propylene Oxide
Amaphuzu okulinganisa abalulekile ahlanganisa i-inlet yempahla eluhlaza, isitsha sokusabela, isigaba sokuhlukanisa kanye nokululama, njll. I-hydrogen peroxide feed inlet iyindawo edingekayo ukuze kuqinisekiswe ukucaciswa okudingekayo. Ngokuvamile, i-hydrogen peroxide igcinwa isesimweni esigxilile, futhi idinga ukuhlanjululwa ngaphambi kokucubungula noma ukusabela kwamanye amakhemikhali.
Bese uze kumkhumbi wokusabela noma i-reactor. Leli elinye iphuzu lokulinganisaisilinganiso sokuhlushwa kwe-hydrogen peroxideukuze ukusabela kuqhubeke njengoba bekulindelekile. An imitha yokuminyana kwenqubo esemgqeninoma enye inzwa iyakwazi ukufakwa endaweni ephumayo ukuze igade ukugcwala kwesikhathi sangempela kwe-hydrogen peroxide njengoba isabela nge-propylene. Abahlakaniphilekwabantu imitha onlineinika amandla ukulungiswa okuguquguqukayo kwe-hydrogen peroxide okunokwenzeka ngokuqapha kwayo okuqhubekayo. Esimeni lapho ukugxilisa kwehla ngokushesha kakhulu noma ukusabela kungayi phambili njengoba kulindelekile, kuyadingeka ukulungisa ukugeleza kwe-hydrogen peroxide kureactor.
Ukusabela kwangemuva kuhilela ukuhlukaniswa nokuhlanzwa kwe-propylene oxide kanye nemikhiqizo, njengamanzi ne-hydrogen peroxide engaphenduliwe. Isibonelo, i-hydrogen peroxide yezinga eliphezulu ibeka engcupheni ekusimameni kwemvelo nokuphepha kwabantu. Ukulinganisa okugxilile okufanelekile kwenza ukulinganisa nokucubungula okusimeme kwenzeke ukuze kuhambisane nemithetho neziqondiso.
Amasistimu okulinganisa ahlakaniphile ezindaweni ezibalulekile enqubeni asiza kakhulu ekwenzeni ukukhiqiza. Ukusebenzisa ubuchwepheshe obuphambili njengeama-densitometers aku-inthanethi, ama-spectrophotometers, nezindlela ze-titration zivumela ukuqapha kwesikhathi sangempela, izilinganiso zokugxilisa ingqondo ezinembile, nokulawula inqubo engcono, ekugcineni kuholele ekuvuthweni okuphezulu nokusebenza okuphephile.
Sicela uxhumaneI-Lonnmeteronjiniyela ukuze uthole ukubonisana okwengeziwe mayelanaemugqeni imitha yokuhlushwa ye-hydrogen peroxide ukuthola ukuthi ingabe ingasetshenziswa kulayini wakho wokukhiqiza noma izitshalo. Cela ikhotheshini yamahhala manje futhi uthole intengo yemitha yokuminyana.
