Ukukhuhla i-amine, okubuye kwaziwe ngokuthi i-amine sweetening, kuyinqubo yamakhemikhali ebalulekile yokubamba amagesi ane-asidi njenge-CO2 noma i-H2S, ikakhulukazi ezimbonini ezifana nezitshalo zokucubungula igesi yemvelo, izitshalo ze-petrochemical, izitshalo ezithuthukisa i-biogas, nezitshalo zokukhiqiza i-hydrogen. Inqubo yokukhuhla i-amine ibalulekile ekukhipheni amagesi ane-acidic afana ne-CO2 noma i-H2S emifudlaneni yegesi ukuvimbela ukugqwala ekuthuthweni okwengeziwe ngokwezidingo zamapayipi.
Kungani Ukugxila Kwe-MDEA Kubalulekile Ekukhuhleni Kwe-Amine
I-MethylDiEthanolAmine (MDEA) iyi-amine esetshenziswa kakhulu ezinhlelweni zokukhuhla i-amine ngenxa yokusebenza kahle kwayo ekukhipheni i-CO2 noma i-H2S ngokukhetha. Ukugcina isixazululo esilungile se-MDEA kubalulekile ngenxa yezizathu ezimbalwa:
- Ukusebenza Kwenqubo:I-Optimal MDEA concentration iqinisekisa ukumuncwa okuphezulu kwamagesi ane-acidic, kunciphisa ukusetshenziswa kwamandla esitshalweni esimnandi se-amine.
- Ukwehliswa Kwezindleko: Ukulawula okunembayo kunciphisa ukusetshenziswa ngokweqile kwe-amine, kwehlisa izindleko zokusebenza kanye nokunciphisa imfucuza.
- Ukuthobela Umthetho: Ukuqapha okunembile kuqinisekisa ukuhambisana nezindinganiso zemvelo ngokususa ngempumelelo i-CO2 noma i-H2S, ukuvumelanisa nezinjongo zokusimama.
Izinselelo Zokulawula Ukugxila Kwe-MDEA
Ukuqapha okugxilile kwe-MDEA okusemgqeni ezinqubweni zokukhuhla i-amine kuhlangabezana nezinselele eziwubuqili ezifana nezilinganiso ezingaguquki, ezingase zidale ukugqwala kwamapayipi kanye nemishini uma kwenzeka igesi ye-asidi i-CO2 noma i-H2S ihluleka ukuthwebula kahle. Ngaphezu kwalokho, ukugxila kwe-amine okungalungile kungakhuphula ukusetshenziswa kwamandla emijikelezweni yokuvuselela, kube nomthelela ekusebenzeni kahle komsebenzi.
Izixazululo ze-Lonnmeter ze-Inline MDEA Concentration Monitoring
Onjiniyela be-lonnmeter banikeze izixazululo ezisebenzayo zokusiza izitshalo ezinjalo eziqondiwe ekuqaphelweni okunembile kwe-MDEA ngokuhlanganisa amayunithi okumnandi kwegesi yemvelo nemitha yokuhlushwa ye-ultrasonic. Ibala isivinini se-sonic ngokuya kwesikhathi sokudlulisela kumidiya elinganisiwe, bese inciphisa ukugxila kwezixazululo ze-amine emifudlaneni.
Ukusebenza komshini ngeke kwehle ngokuhamba kwesikhathi kungabikho izingxenye ezihambayo. Inzwa ibala isivinini se-sonic ngebanga elingashintshi phakathi kwesidlulisi se-ultrasonic nomamukeli. Indlela yokulinganisa ayivinjwanga yi-conductivity, umbala nokungafihli kwemidiya ngenkathi igcina ukwethembeka nokunemba okuphelele kufika ku-0.05%.
Abahlaziyi be-amine baklanyelwe ukubhekana nezinselele zokulawula ukugxilisa ingqondo kwe-MDEA okusemgqeni, okuvumela ukuqapha idatha ngesikhathi sangempela nokunciphisa imvamisa yokulungisa kanye nesikhathi sokuvala imishini.
Imikhiqizo Enconyiwe
Izinzuzo Zezinzwa Zenqubo Ye-Lonnmeter
Ukunemba Okungalindelekile
Imitha yokugxilisa i-amine ukunemba okungenakuqhathaniswa 0.05%~0.1%. Lokhu kunemba okukhethekile kuqinisekisa ukugadwa okunembayo kokugxila kwe-MDEA ezinqubweni ezifana nobumnandi begesi yemvelo kanye ne-CO.2ukukhuhla i-amine, okuvumela ukumuncwa okufanele kwamagesi ane-asidi njenge-CO2noma H2S ngenkathi kunciphisa ukusetshenziswa kwamandla kanye nokuchithwa kwe-amine.
Ukuqapha Nezilungiso Zesikhathi Sangempela
Ukuhlanganiswa kwayo okungenamthungo nezinhlelo ze-PLC kanye ne-DCS ngezivumelwano ezijwayelekile ezifana ne-4-20mA ne-RS 485 kunika amandla ukudluliswa kwedatha kwesikhathi sangempela, okuvumela ukulungiswa kwenqubo ngokushesha. Lokhu kunciphisa ukumosheka kwamandla kusukela ekuvuselelweni kabusha, konga kufikela ku-15-20% ezindlekweni zamandla egesi yemvelo enoshukela ngesisombululo se-amine.
Ukwehliswa Kwezindleko
Ngokuthuthukisa ukulawulwa kokugxilisa kwesisombululo se-MDEA, lezi zinzwa zinciphisa ukusetshenziswa kwamandla, zinciphisa ukumosheka kwe-amine, izindleko zokulungisa eziphansi, futhi zinqande isikhathi sokuphumula ezibizayo, zizenze zibe isiguquli esishintshashintshayo sezitshalo ze-amine ezinoshukela ezilungiselela igesi yemvelo emuncu yokuthutha amapayipi aphephile kuyilapho igwema izindleko ezihlobene nokugqwala.
Ukuqapha okunembile kuvimbela ukuwohloka kwe-amine ekugxiliseni okungafanele, kunwebe impilo esebenzisekayo yezixazululo ze-MDEA. Lokhu kunciphisa imvamisa yokushintshanisa, kwehlisa izindleko zokuthengwa kwamakhemikhali ngo-5-10% ngonyaka.
Imibuzo Evame Ukubuzwa
Iyini i-Amine Scrubbing futhi Kungani I-MDEA Isetshenziswa?
Ukukhuhla i-amine kuyinqubo esetshenziswa ezitshalweni zegesi ye-amine emnandi ukususa amagesi ane-acidic njenge-CO2 noma i-H2S emifudlaneni yegesi. I-MDEA ithandwa ngenxa yokukhethwa kwayo okuphezulu kwe-CO2 ne-H2S, izimfuneko eziphansi zamandla zokwenziwa kabusha, kanye nokuncipha kokubola.
Yiziphi Izinzuzo Zokuqapha Kwesikhathi Sangempela se-MDEA?
Ukuqapha kwesikhathi sangempela ngamamitha okugxilisa ingqondo e-MDEA kunikeza idatha esheshayo emazingeni e-amine, okuvumela ukulungiswa okusheshayo ukuze kugcinwe ukusebenza kahle. Izinzuzo zifaka ukusetshenziswa okuncishisiwe kwamandla, ukusetshenziswa kwe-amine okuphansi, ukuphila kwemishini enwetshiwe, nokuhambisana nemigomo yokusimama kushukela wegesi yemvelo ngesisombululo se-amine.
Ukulawula ukugxila kwe-MDEA okungaphakathi kwe-line kubalulekile ekwandiseni izinqubo zoshukela we-amine ezimbonini ezicubungula igesi yemvelo, izitshalo ze-petrochemical, izitshalo ezithuthukisa i-biogas, nezitshalo zokukhiqiza i-hydrogen. Ngokubhekana nezinselelo ezifana nezilinganiso ezingaguquki, ukusetshenziswa kwamandla okuphezulu, amamitha wokugxilisa we-MDEA kunika amabhizinisi amandla okufeza ukusebenza kahle, ukwehlisa izindleko, nokuzinza.
