Ukukhuhla i-amine, ekwabizwa ngokuba yi-amine sweetening, yinkqubo yeekhemikhali eyimfuneko yokubamba iigesi ze-asidi ezifana ne-CO2 okanye i-H2S, ngakumbi kumashishini afana nezityalo zokulungisa igesi yendalo, izityalo ze-petrochemical, izityalo zokuphucula i-biogas, kunye nezityalo zokuvelisa i-hydrogen. Inkqubo yokukhuhla i-amine ibalulekile ekususeni iigesi ezineasidi ezifana ne-CO2 okanye i-H2S kwimijelo yerhasi ukuthintela ukubola kwizithuthi eziqhubekayo ngokweemfuno zemibhobho.
Kutheni i-MDEA ibalulekile kwi-Amine Scrubbing
I-MethylDiEthanolAmine (MDEA) yi-amine esetyenziswa ngokubanzi kwiinkqubo zokukhuhla i-amine ngenxa yokusebenza kwayo ekukhetheni ukususa i-CO2 okanye i-H2S. Ukugcina ugxininiso lwesisombululo se-MDEA esichanekileyo kubalulekile ngenxa yezizathu ezininzi:
- Inkqubo eSebenzayo:Ugxininiso lwe-MDEA olufanelekileyo luqinisekisa ukufunxwa okuphezulu kweegesi ezine-acidic, ukunciphisa ukusetyenziswa kwamandla kwisityalo se-amine esimnandi.
- UkuNcitshiswa kweendleko: Ulawulo oluchanekileyo lunciphisa ukusetyenziswa ngokugqithisileyo kwe-amine, ukuthoba iindleko zokusebenza kunye nokunciphisa inkunkuma.
- Ukuthotyelwa koMgaqo: Ukubeka iliso ngokuchanekileyo kuqinisekisa ukuthotyelwa kwemigangatho yokusingqongileyo ngokususa ngokufanelekileyo i-CO2 okanye i-H2S, ukulungelelanisa neenjongo zokuzinza.
Imingeni ekuLawulweni kwe-MDEA yokuMamela
Ukujongwa okungaphakathi kwe-MDEA kwiinkqubo zokukhuhla i-amine idibana nemiceli mngeni yobuqhinga njengemilinganiselo engangqinelaniyo, enokubangela ukonakala kwemibhobho kunye nezixhobo kwimeko yokuba irhasi yeasidi i-CO2 okanye i-H2S ingabanjwa ngokucokisekileyo. Ngaphezu koko, ukugxilwa kwe-amine okungachanekanga kunokonyusa ukusetyenziswa kwamandla kwimijikelo yokuvuselela, okuchaphazela ukusebenza kakuhle.
Izisombululo zeLonnmeter zoHlolo loQwalaselo lwe-MDEA olungaphakathi
Iinjineli ze-lonnmeter zibonelele ngezisombululo ezisebenzayo zokunceda izityalo ekujoliswe kuzo kwi-MDEA echanekileyo yokubeka iliso ngokudibanisa iiyunithi zegesi yendalo emnandi kunye nemitha yoxinaniso ye-ultrasonic. Ibala isantya se-sonic ngokwexesha lothumelo kwimidiya elinganisiweyo, emva koko i-infer concentration yezisombululo ze-amine kwimisinga.
Ukusebenza koomatshini akuyi kuthotywa kunye nexesha kungabikho malungu ahambayo. Inzwa ibala isantya se-sonic ngomgama osisigxina phakathi kwe-ultrasonic transmitter kunye nomamkeli. Indlela yokulinganisa ayinyanzelwanga yi-conductivity, umbala kunye nokungafihli kweendaba ngelixa ugcina ukuthembeka okuphezulu kunye nokuchaneka ukuya kwi-0.05%.
Abahlalutyi boxinaniso lwe-amine benzelwe ukujongana nemingeni yolawulo loxinaniso lwe-MDEA olungaphakathi, ukunika iliso lexesha lokwenyani ledatha kunye nokunciphisa ukugcinwa rhoqo kunye nexesha lokuvalwa kwezixhobo.

Okuzuzwayo kwiiSensors zeNkqubo yeLonnmeter
Ukuchaneka okungalindelekanga
Imitha yoxinzelelo lwe-amine engahambelani nokuchaneka kwe-0.05% ~ 0.1%. Oku kuchaneka kukhethekileyo kuqinisekisa uqwalaselo oluchanekileyo lwe-MDEA yoxinaniso kwiinkqubo ezifana negesi yendalo eswiti kunye neCO.2ukukhuhla i-amine, okwenza ukufunxwa ngokufanelekileyo kweegesi ezineasidi njenge-CO2okanye H2S ngelixa kuncitshiswa ukusetyenziswa kwamandla kunye nokuchithwa kwe-amine.
Ukubeka iliso ngexesha lokwenyani kunye noLungiso
Ukuhlanganiswa kwayo okungenamthungo kunye ne-PLC kunye neenkqubo ze-DCS ngeeprothokholi eziqhelekileyo ezifana ne-4-20mA kunye ne-RS 485 yenza ukuhanjiswa kwedatha ngexesha langempela, ivumela uhlengahlengiso lwenkqubo olukhawulezileyo. Oku kunciphisa inkcitho yamandla ukusuka ekuvuselelweni ngokutsha, ukonga ukuya kuthi ga kwi-15-20% kwiindleko zamandla kwigesi yendalo eswiti ngesisombululo seamine.
UkuNcitshiswa kweendleko
Ngokusebenzisa ulawulo loxinaniso lwesisombululo se-MDEA, ezi zivamvo zinciphisa ukusetyenziswa kwamandla, ukunciphisa inkcitho ye-amine, ukuthoba iindleko zokulondolozwa, kunye nokuthintela ixesha lokuphumla elineendleko eziphezulu, kubenza ukuba batshintshe umdlalo wezityalo zegesi ezinencasa ye-amine zilungiselela irhasi emuncu yendalo yothutho lwemibhobho ekhuselekileyo ngelixa unqanda iindleko ezinxulumene nomhlwa.
Ukubeka iliso okuchanekileyo kuthintela ukuthotywa kwe-amine ekugxininiseni okungafanelekanga, ukwandisa ubomi obusebenzisekayo bezisombululo ze-MDEA. Oku kunciphisa ukuphindaphindeka kokutshintshwa, ukunciphisa iindleko zokuthengwa kweekhemikhali nge-5-10% ngonyaka.
