Ukucola i-amine, okwaziwa ngokuba yi-amine sweetening, yinkqubo ebalulekileyo yeekhemikhali yokubamba iigesi ze-asidi ezifana ne-CO2 okanye i-H2S, ingakumbi kumashishini afana nezityalo zokucubungula igesi yendalo, izityalo ze-petrochemical, izityalo zokuphucula i-biogas, kunye nezityalo zokuvelisa i-hydrogen. Inkqubo yokucola i-amine ibalulekile ekususeni iigesi ze-asidi ezifana ne-CO2 okanye i-H2S kwimithombo yegesi ukuthintela ukugqwala ekuthuthweni okungakumbi ngokweemfuno zemibhobho.
Kutheni i-MDEA Concentration ibalulekile kwi-Amine Scrubbing
I-MethylDiEthanolAmine (MDEA) yi-amine esetyenziswa kakhulu kwiinkqubo zokuhlafuna i-amine ngenxa yokusebenza kwayo kakuhle ekususeni i-CO2 okanye i-H2S ngokukhetha. Ukugcina uxinano olufanelekileyo lwesisombululo se-MDEA kubalulekile ngezizathu ezahlukeneyo:
- Ukusebenza kakuhle kwenkqubo:Uxinzelelo olufanelekileyo lwe-MDEA luqinisekisa ukufunxwa okuphezulu kweegesi ezine-asidi, kunciphisa ukusetyenziswa kwamandla kwisityalo sokwenza i-amine gas sweetening.
- Ukuncitshiswa kweendleko: Ulawulo oluchanekileyo lunciphisa ukusetyenziswa kakhulu kwe-amine, lunciphisa iindleko zokusebenza kwaye lunciphisa inkunkuma.
- Ukuthotyelwa kweMithetho: Ukubeka esweni ngokuchanekileyo kuqinisekisa ukuthotyelwa kwemigangatho yokusingqongileyo ngokususa ngempumelelo i-CO2 okanye i-H2S, kuhambelana neenjongo zozinzo.
Imingeni ekulawuleni ukugxila kwe-MDEA
Ukubeka iliso kuxinzelelo lwe-MDEA kwiinkqubo zokucola i-amine kuhlangana nemingeni enzima efana nokulinganisa okungahambelaniyo, okunokubangela ukubola kwemibhobho nezixhobo ukuba igesi ye-asidi ye-CO2 okanye i-H2S ayibanjwanga kakuhle. Ngaphezu koko, uxinano olungachanekanga lwe-amine lunokunyusa ukusetyenziswa kwamandla kwimijikelo yokuvuselela, nto leyo echaphazela ukusebenza kakuhle.
Izisombululo zeLonnmeter zokubeka iliso kwi-Inline MDEA Concentration Monitoring
Iinjineli ze-lonnmeter zibonelele ngezisombululo ezisebenzayo ukunceda izityalo ezijolise kuzo ekujongeni ngokuchanekileyo uxinaniso lwe-MDEA ngokudibanisa iiyunithi zokuthambisa igesi yendalo kunye nemitha yoxinaniso ye-ultrasonic. Ibala isantya sesandi ngokwexesha lokudlulisela kwimidiya elinganisiweyo, ize igqibe uxinaniso lwezisombululo ze-amine kwimilambo.
Ukusebenza koomatshini akuyi kuncipha ngokuhamba kwexesha ngaphandle kweendawo ezishukumayo. I-sensor ibala isantya sesandi ngomgama omiselweyo phakathi kwe-transmitter ye-ultrasonic kunye ne-receiver. Indlela yokulinganisa ayithintelwanga yi-conductivity, umbala kunye nokucaca kwemidiya ngelixa igcina ukuthembeka kunye nokuchaneka okuphezulu ukuya kuthi ga kwi-0.05%.
Abahlalutyi boxinzelelo lwe-amine benzelwe ukujongana nemingeni yolawulo loxinzelelo lwe-MDEA oluhambelanayo, oluvumela ukujonga idatha ngexesha langempela kunye nokunciphisa amaxesha okugcinwa kunye nexesha lokuvalwa kwezixhobo.

Ukuchaneka Okungalindelekanga
Imitha yoxinzelelo lwe-amine echanekileyo kakhulu yi-0.05% ~ 0.1%. Olu chanekileyo lubalaseleyo luqinisekisa ukubekwa esweni ngokuchanekileyo koxinzelelo lwe-MDEA kwiinkqubo ezifana nokuthambisa igesi yendalo kunye ne-CO2.2ukukrwela i-amine, okuvumela ukufunxwa kakuhle kweegesi ezine-asidi ezifana ne-CO22okanye u-H2S ngelixa kunciphisa ukusetyenziswa kwamandla kunye nenkunkuma ye-amine.
Ukubeka esweni kunye nohlengahlengiso ngexesha langempela
Ukuhlanganiswa kwayo okungenamthungo neenkqubo ze-PLC kunye ne-DCS ngokusebenzisa iiprotokholi ezisemgangathweni ezifana ne-4-20mA kunye ne-RS 485 kwenza ukuba idatha idluliselwe ngexesha langempela, okuvumela uhlengahlengiso lwenkqubo ngokukhawuleza. Oku kunciphisa inkunkuma yamandla evela ekuvuseleleni kakhulu, konga ukuya kuthi ga kwi-15-20% kwiindleko zamandla ekuthambiseni igesi yendalo ngesisombululo se-amine.
Ukuncitshiswa kweendleko
Ngokuphucula ulawulo loxinzelelo lwesisombululo se-MDEA, ezi sensors zinciphisa ukusetyenziswa kwamandla, zinciphisa inkunkuma ye-amine, zinciphise iindleko zokulungisa, kwaye zithintele ixesha lokungasebenzi elibizayo, nto leyo ezenza zibe zizinto ezitshintsha umdlalo kwizityalo ezilungisa igesi ye-amine ezilungiselela igesi yendalo emuncu ukuze zithuthwe ngokukhuselekileyo kwimibhobho ngelixa ziphepha iindleko ezinxulumene nokugqwala.
Ukubeka esweni ngokuchanekileyo kuthintela ukuwohloka kwe-amine ekuxinaniseni okungafanelekanga, nto leyo eyandisa ubomi obusebenzisekayo bezisombululo ze-MDEA. Oku kunciphisa ukuphindaphinda kokutshintshwa, kunciphisa iindleko zokuthengwa kweekhemikhali nge-5-10% ngonyaka.
