Propylene oxide inotorwa sechikamu chepakati mukugadzirwa kwepolyurethane, antifreeze nemamwe makemikari emaindasitiri.mita yekuwanda kwepombiYakabatanidzwa mumutsara wekugadzira wepropylene oxide manufacturing facility -- Propylene Oxide Plant kuti ikwanise kudzora makemikari, umo reactant imwe inokoshahydrogen peroxide (H₂O₂)Inosangana nepropylene kana paine chinhu chinoita kuti igadzire propylene oxide.
Mwero wekuita, mhando yechigadzirwa uye kushanda zvakanaka kwese zvese zvinogona kugadziriswa kuburikidza nemita yekuyera hydrogen peroxidepamatanho akasiyana-siyana ekugadzirwa. Mhinduro huru inotsamira pakuita kwe epoxidation, apo propylene inodyidzana ne hydrogen peroxide (H₂O₂) pamberi pe catalyst (kazhinji kacho tungstate kana molybdate-based catalyst) kuti igadzire propylene oxide (C₃H₆O) nemvura (H₂O).
Kuyera Mapoinzi muKugadzirwa kwePropylene Oxide
Nzvimbo dzekuyera dzakakosha dzinosanganisira kupinda kwezvinhu zvisina kugadzirwa, midziyo yekuita, kupatsanurwa uye kudzoreredzwa, nezvimwewo. Kupinda kwehydrogen peroxide feed inzvimbo inodiwa kuti ive nechokwadi chekuti zvinodiwa. Kazhinji, hydrogen peroxide inochengetwa muchimiro chakasimba, uye inofanira kusanganiswa isati yagadziriswazve kana kusanganiswa nemamwe makemikari.
Wobva wauya kumudziyo wereaction kana reactor. Iyi imwe nzvimbo yekuyerakuyerwa kwehuwandu hwehydrogen peroxidekuitira kuti maitiro ari kufambira mberi sezvaitarisirwa. mita yekuwanda kwemaitiro ari mukatikana imwe sensor inokwanisa kuiswa panzvimbo yekubuditsa reactor kuti iongorore huwandu hwehydrogen peroxide panguva chaiyo painosangana nepropylene.mita yehuwandu hwevanhu onlinezvinoita kuti hydrogen peroxide igadziriswe zvine simba kuti irambe ichiongororwa. Kana huwandu hwayo hukadonha nekukurumidza kana kuti mhinduro ikasaenderera mberi sezvaitarisirwa, zvinodikanwa kuti hydrogen peroxide ipinde mureactor.
Mushure mekupindura kunosanganisira kupatsanurwa nekucheneswa kwepropylene oxide nezvimwe zvinhu zvinobva muzvinhu izvi, zvakaita semvura nehydrogen peroxide isina kugadziriswa. Semuenzaniso, hydrogen peroxide yepamusoro inokonzera njodzi kukuchengetedza nharaunda uye kuchengetedzeka kwevanhu. Kuyerwa kwakakodzera kwehuwandu hwezvinhu kunoita kuti kuyera huwandu hwezvinhu uye kugadzirisa zvinhu nenzira inochengetedza nharaunda kuenderane nemitemo.
Masisitimu ekuyera akangwara panguva dzakakosha mukuita izvi anobatsira zvikuru mukugadzirisa kugadzirwa. Kushandisa matekinoroji epamusoro akadai semadensitometer epamhepo, maspectrophotometer, uye nzira dzetitration zvinobvumira kutarisa panguva chaiyo, kuyerwa kwakarurama kwekuyera, uye kudzora maitiro zviri nani, zvichizopedzisira zvaita kuti pave negoho rakawanda uye mashandiro akachengeteka.
Ndapota taurai nesuLonnmetermainjiniya kuti muwane rumwe ruzivo nezvemukati mita yekuyera hydrogen peroxide kuti muone kana ichigona kushandiswa pakugadzira kwenyu kana mumafekitori. Kumbira mutengo wemahara izvozvi uye uwane mutengo wemita yehuremu.
