Kwiinkqubo zomphunga kunye nebhoyila, umhlwa uthande ukuba mandundu ngokuthe cwaka. Ngexesha leediphozithi ezibonisa ukutshintshiselana kobushushu okanye ukonyuka kwamaza okuvalwa, imigca ye-condensate ibisoloko iphantsi kohlaselo okwethutyana.
I-Morpholine kunye ne-Cyclohexylamine zombini zisetyenziselwa unyango lwamanzi kwibhoyila ukujongana nale nto - ngokukodwa ukunciphisa i-carbonic acid eyenza xa i-CO₂ ichitheka kwi-condensate. Basebenza ngendlela efanayo kodwa baziphatha ngendlela eyahlukileyo xa bengena kwinkqubo, yiyo loo nto ukukhetha phakathi kwabo ingengombandela wokufumaneka okanye ixabiso.
Ngamagama alula, i-Morpholine kunye ne-Cyclohexylamine zombini zisetyenziselwa ukukhusela iinkqubo ze-steam kunye ne-condensate kwi-corrosion ye-asidi. Umahluko kulapho basebenza khona ngcono kwinkqubo. I-Morpholine ifaneleke ngakumbi kumacandelo e-condensate akufutshane, ngelixa i-Cyclohexylamine inokuhamba ngakumbi ngomphunga kwaye ixhase imigca ye-condensate ekude.
Kutheni Ukonakala kweCondensate Kwenzeka
Umhlwa womgca wecondensate udla ngokunxulumana nekharbon diokside kwinkqubo yomphunga. Xa i-steam idibanisa, i-CO₂ edibeneyo inokwenza i-carbonic acid kwi-condensate. Le acidic condensate inokuhlasela i-carbon steel pipework kunye nezinye iindawo zentsimbi.
I-amines engathathi hlangothi inceda ukunciphisa le ngxaki ngokuthwala inkqubo ye-steam kunye nokuchithwa kwi-condensate njengoko ifom. Indima yabo kukunyusa i-pH ye-condensate kunye nokunciphisa ukuhlaselwa kwe-asidi. I-amine elungileyo ixhomekeke kubume benkqubo, uxinzelelo lomphunga, indlela yokubuya ye-condensate kunye nalapho kuvela khona umhlwa.
Umahluko ophambili phakathiiiiiiiaminesyindlela yokuziphatha yabo yokuhambisa. Ezinye i-amines zingena kwisigaba se-condensate ngokukhawuleza, ngelixa ezinye zihlala ixesha elide kwisigaba somphunga kwaye zihamba phambili ngaphambi kokuba zigxininise kwi-condensate.
NjaniMorpholineIsebenza kwiiNkqubo zeSteam
I-Morpholine, i-CAS 110-91-8, i-amine engathathi hlangothi esetyenziselwa unyango lwe-steam kunye ne-condensate. Xa kuthelekiswa ne-Cyclohexylamine, iMorpholine iqheleke ngakumbi kwi-condensate. Oku kuthetha ukuba kudla ngokuxoxwa kwiinkqubo apho ulawulo lwe-pH lufuneka kumacandelo akufutshane e-condensate okanye apho ukungathathi hlangothi kwe-condensate okuthe ngqo kuyadingeka.
Kwiinkqubo ezininzi ezisemgangathweni zomphunga, iMorpholine inokuba yinto esebenzayo kuba ixhasa uhlengahlengiso lwe-pH ye-condensate ngaphandle kokuxhomekeka kuphela kuhambo olude lomphunga. Ikwasetyenziswa nakwamanye amasimi amashishini, kubandakanywa ukuhlanganiswa kweekhemikhali, imveliso enxulumene namayeza kunye nosetyenziso oluphakathi lwe-agrochemical.
Kubathengi, ingongoma ebalulekileyo kukuba i-Morpholine ayifanele ikhethwe kuphela ngegama lemveliso. Uyilo olululo lomphunga, imeko yokubuyisela i-condensate kunye nenkqubo yokucoca amanzi zonke zichaphazela ukuba zifanelekile na.
NjaniCyclohexylamineIsebenza kwiiNkqubo zeSteam
I-Cyclohexylamine, i-CAS 108-91-8, inomlinganiselo ophezulu wokusabalalisa isigaba se-steam kune-Morpholine. Ikholisa ukuhlala kwisigaba somphunga ixesha elide kwaye inokuhamba ngakumbi kwinkqubo ngaphambi kokuba inyibilike ibe yicondensate.
Oku kwenza i-Cyclohexylamine ibe luncedo kwiinkqubo ezinemigca emide yokuhambisa umphunga okanye amacandelo e-condensate ekude. Xa i-corrosion ibonakala ikude kwibhoyila, i-amine yokusabalalisa okuphezulu inokuqwalaselwa njengenxalenye yenkqubo yonyango.
Ngenxa yokuba i-Cyclohexylamine inokuguquguquka okunamandla kunye nephunga elinamandla le-amine, i-dosing kunye neemeko zokusebenza kufuneka zihlaziywe ngononophelo liqela lokunyanga amanzi. Ngokuqhelekileyo ikhethwa ngokwemeko yenkqubo kunokuba ithathe indawo elula yeMorpholine.
I-Morpholine okanye i-Cyclohexylamine: Yeyiphi Efaneleka Ngcono?
Ukhetho luxhomekeke apho kufuneka ukhuseleko.
Kwiinkqubo ezinobude obufutshane okanye obuphakathi bomgca womphunga, okanye apho kufuneka ulawulo lwe-pH yecondensate kufutshane nebhoyila, iMorpholine inokufaneleka. Kwiinkqubo ezinemigca emide yomphunga, amacandelo anoxinzelelo oluphantsi okanye iingxaki zokubola kwiindawo ezikude zokubuyiswa kwe-condensate, i-Cyclohexylamine inokubonelela ngokhuseleko olungcono.
Kwezinye iinkqubo zokunyanga amanzi kwibhoyila, ngaphezu kwe-amine enye yokungathathi hlangothi ingasetyenziswa. Indlela edibeneyo inokunceda ukulungelelanisa ukukhuselwa kwiindawo ezahlukeneyo ze-steam kunye ne-condensate system. Ngokomzekelo, enye i-amine inokuxhasa amacandelo e-condensate akufutshane, ngelixa enye inokunceda ukuthwala unyango ngakumbi kwinethiwekhi yokusabalalisa.
Esi sigqibo kufuneka senziwe ngokusekelwe kuyilo lwenkqubo, uvavanyo lwe-condensate, i-pH ekujoliswe kuyo kunye namava okusebenza.
