Propylene oxide waxaa loo qaataa sidii dhex dhexaad u ah soo saarista polyurethane, antifreeze iyo kiimikooyinka kale ee warshadaha. Amitirka cufnaanta dhuumahaWaxay ku dhex milmay khadka wax soo saarka ee xarunta wax soo saarka propylene oxide -- Propylene Oxide Plant si loo xakameeyo saxda ah falcelinta kiimikada, taas oo hal falcelin muhiim ahhydrogen peroxide (H₂O₂)waxay la falgashaa propylene iyadoo ay jirto kiciye si uu u sameeyo propylene oxide.
Heerka falcelinta, tayada alaabta iyo guud ahaan waxtarka dhammaan waxa lagu hagaajin karaa amitirka fiirsashada hydrogen peroxideheerarka kala duwan ee wax soo saarka. Dareen-celinta ugu weyni waxay ku sii jirtaa falcelinta epioxidation, halkaas oo propylene ay la falgasho hydrogen peroxide (H₂O₂) joogitaanka kicinta (sida caadiga ah tungstate ama molybdate ku salaysan) si ay u sameeyaan propylene oxide (C₃H₆O) iyo biyo (H₂O).
Cabbiraadda Dhibcaha ee Soo-saarka Propylene Oxide
Qodobbada cabbiraadda muhiimka ah waxaa ka mid ah gelitaanka alaabta ceeriin, weelka falcelinta, marxaladda kala-soocidda iyo soo kabashada, iwm. Gelitaanka quudinta hydrogen peroxide waa barta lagama maarmaanka ah si loo hubiyo qeexida loo baahan yahay. Guud ahaan, hydrogen peroxide waxay ku kaydsan tahay qaab xoog leh, waxayna u baahan tahay in la qaso ka hor inta aan la sii wadin ama falcelinta kiimikooyinka kale.
Kadib u imow weelka falcelinta ama reactor-ka. Tani waa bar kale oo lagu cabbirocabbirka feejignaanta hydrogen peroxidesi fal-celintu u socoto sidii la filayey. An mitirka cufnaanta habka inlineama dareemaha kale ayaa awood u leh in lagu rakibo qalabka reactor-ka si uu ula socdo feejignaanta wakhtiga dhabta ah ee hydrogen peroxide sida ay ula falgasho propylene. Waxgaradkiimitirka cufnaanta onlaynwaxa ay awood u siinaysaa hagaajinta firfircoonida hydrogen peroxide ee suurtogalka ah kormeerkeeda joogtada ah. Lacalla haddii xooga-saarku si dhakhso ah u dhaco ama fal-celintu u socon waydo sidii la filayey, waa lagama maarmaan in la hagaajiyo socodka hydrogen peroxide gudaha reactor.
Falcelinta ka dib waxay ku lug leedahay kala-soocidda iyo nadiifinta propylene oxide iyo alaabta ka soo baxda, sida biyaha iyo hydrogen peroxide oo aan la falgelin. Tusaale ahaan, hydrogen peroxide oo heerka sare ah waxay khatar ku tahay sii jirista deegaanka iyo badbaadada aadanaha. Cabbirka feejignaanta saxda ah wuxuu ka dhigayaa qiyaasid iyo habayn waara oo suurtagal ah si loogu hoggaansamo sharciyada iyo xeerarka.
Nidaamyada cabbiraadda caqliga leh ee meelaha muhiimka ah ee geeddi-socodka ayaa wax badan ka caawiya hagaajinta wax-soo-saarka. Adeegsiga tignoolajiyada horumarsan sidadensitometer online, spectrophotometers, iyo hababka titration waxay u ogolaataa la socodka waqtiga-dhabta ah, cabbirada fiirsashada saxda ah, iyo xakamaynta habka wanagsan, ugu dambeyntii taasoo keenta wax soo saar sare iyo hawlgalo badbaado leh.
