Ukuhlafuna ama-amine, okwaziwa nangokuthi ukunandisa ama-amine, kuyinqubo ebalulekile yamakhemikhali yokubamba amagesi e-asidi njenge-CO2 noma i-H2S, ikakhulukazi ezimbonini ezifana nezitshalo zokucubungula igesi yemvelo, izitshalo ze-petrochemical, izitshalo zokuthuthukisa i-biogas, kanye nezitshalo zokukhiqiza i-hydrogen. Inqubo yokuhlafuna ama-amine ibalulekile ekususeni amagesi ane-asidi njenge-CO2 noma i-H2S emifuleni yegesi ukuvimbela ukugqwala ekuthuthweni okuqhubekayo ngokwezidingo zamapayipi.
Kungani Ukugxila kwe-MDEA Kubalulekile Ekuhlafuneni Ama-Amine
I-MethylDiEthanolAmine (MDEA) iyi-amine esetshenziswa kabanzi ezinhlelweni zokuhlanza ama-amine ngenxa yokusebenza kwayo kahle ekususeni i-CO2 noma i-H2S ngokukhetha. Ukugcina ukuhlushwa kwesisombululo se-MDEA esifanele kubalulekile ngezizathu eziningana:
- Ukusebenza Kahle Kwenqubo:Ukuhlushwa okuhle kwe-MDEA kuqinisekisa ukumuncwa okuphezulu kwamagesi ane-asidi, kunciphisa ukusetshenziswa kwamandla esitshalweni sokwenza ubumnandi begesi ye-amine.
- Ukwehliswa Kwezindleko: Ukulawula okunembile kunciphisa ukusetshenziswa ngokweqile kwama-amine, kunciphisa izindleko zokusebenza kanye nokunciphisa imfucuza.
- Ukuthobela Imithetho: Ukuqapha okunembile kuqinisekisa ukuhambisana nezindinganiso zemvelo ngokususa ngempumelelo i-CO2 noma i-H2S, okuhambisana nemigomo yokusimama.
Izinselele Ekulawuleni Ukugxila Kwe-MDEA
Ukuqapha ukuhlushwa kwe-MDEA okuqondile ezinqubweni zokuhlanza ama-amine kuhlangabezana nezinselele ezinzima njengokulinganisa okungaguquki, okungase kubangele ukugqwala kwamapayipi kanye nemishini uma kwenzeka igesi ye-asidi i-CO2 noma i-H2S yehluleka ukubanjwa kahle. Ngaphezu kwalokho, ukuhlushwa kwama-amine okungafanele kungandisa ukusetshenziswa kwamandla emijikelezweni yokuvuselela, okuthinta ukusebenza kahle kokusebenza.
Izixazululo zeLonnmeter Zokuqapha Ukugxila Kwe-Inline MDEA
Onjiniyela be-lonnmeter banikeze izixazululo ezisebenzayo zokusiza izitshalo ezinjalo ekuqapheni okuqondile kokuhlushwa kwe-MDEA ngokuhlanganisa amayunithi okumnandi kwegesi yemvelo nemitha yokuhlushwa ye-ultrasonic. Ibala ijubane le-sonic ngokuya ngesikhathi sokudlulisa kumidiya elinganisiwe, bese inquma ukuhlushwa kwezixazululo ze-amine emifudlaneni.
Ukusebenza komshini ngeke kuphele ngokuhamba kwesikhathi ngaphandle kwezingxenye ezihambayo. Inzwa ibala ijubane le-sonic ngebanga eliqondile phakathi komthumeli we-ultrasonic kanye nomemukeli. Indlela yokulinganisa ayivinjelwanga ukuhanjiswa, umbala kanye nokucaca kwemidiya ngenkathi igcina ukuthembeka okuphezulu kanye nokunemba kufika ku-0.05%.
Abahlaziyi bokuhlushwa kwe-amine baklanyelwe ukubhekana nezinselele zokulawulwa kokuhlushwa kwe-MDEA okuqondile, okuvumela ukuqapha idatha ngesikhathi sangempela nokunciphisa imvamisa yokulungisa kanye nesikhathi sokuvala imishini.
Imikhiqizo Enconyiwe
Izinzuzo Zezinzwa Zenqubo Ye-Lonnmeter
Ukunemba Okungalindelekile
Imitha yokuhlushwa kwe-amine ayinakuqhathaniswa ngokunemba okungu-0.05% ~ 0.1%. Lokhu kunemba okumangalisayo kuqinisekisa ukuqapha okunembile kokuhlushwa kwe-MDEA ezinqubweni ezifana nokunambitheka kwegesi yemvelo kanye ne-CO2.2ukuhlafuna ama-amine, okuvumela ukumuncwa okuhle kwamagesi ane-asidi njenge-CO22noma u-H2S ngenkathi kunciphisa ukusetshenziswa kwamandla kanye nokulahlwa kwama-amine.
Ukuqapha Nokulungisa Ngesikhathi Sangempela
Ukuhlanganiswa kwayo okungenamthungo nezinhlelo ze-PLC kanye ne-DCS ngokusebenzisa amaphrothokholi ajwayelekile njenge-4-20mA kanye ne-RS 485 kwenza kube lula ukudluliswa kwedatha ngesikhathi sangempela, okuvumela ukulungiswa kwenqubo ngokushesha. Lokhu kunciphisa ukuchithwa kwamandla okuvela ekuvuseleleni ngokweqile, konga kufika ku-15-20% ezindlekweni zamandla ekunambithekeni kwegesi yemvelo ngesisombululo se-amine.
Ukwehliswa Kwezindleko
Ngokwenza ngcono ukulawulwa kokuhlushwa kwesisombululo se-MDEA, lezi zinzwa zinciphisa ukusetshenziswa kwamandla, zinciphise imfucuza yama-amine, zinciphise izindleko zokulungisa, futhi zivimbele isikhathi sokungasebenzi esibizayo, okwenza zibe yinto eshintsha umdlalo wezitshalo ezithuthukisa igesi yama-amine ezilungiselela igesi yemvelo emuncu ukuze ithuthwe ngepayipi eliphephile ngenkathi zigwema izindleko ezihlobene nokugqwala.
Ukuqapha okunembile kuvimbela ukuwohloka kwama-amine ekugxiliseni okungafanele, kwandise impilo esebenzisekayo yezixazululo ze-MDEA. Lokhu kunciphisa imvamisa yokushintsha, kunciphisa izindleko zokuthengwa kwamakhemikhali ngo-5-10% ngonyaka.
Imibuzo Evame Ukubuzwa
Kuyini i-Amine Scrubbing futhi kungani kusetshenziswa i-MDEA?
Ukuhlikihla nge-amine kuyinqubo esetshenziswa ezitshalweni zokwenza i-amine gas sweetening ukususa amagesi ane-asidi njenge-CO2 noma i-H2S emifudlaneni yegesi. I-MDEA iyathandwa ngenxa yokukhetha kwayo okuphezulu kwe-CO2 ne-H2S, izidingo zamandla eziphansi zokuvuselela, kanye nokunciphisa ukugqwala.
Yiziphi Izinzuzo Zokuqapha Ukugxila Kwe-MDEA Ngesikhathi Sangempela?
Ukuqapha ngesikhathi sangempela ngamamitha okuhlushwa e-MDEA kunikeza idatha esheshayo ngamazinga e-amine, okuvumela ukulungiswa okusheshayo ukuze kulondolozwe ukusebenza kahle. Izinzuzo zifaka phakathi ukusetshenziswa kwamandla okuncishisiwe, ukusetshenziswa kwe-amine okuphansi, impilo yemishini ende, kanye nokuhambisana nemigomo yokuzinza ekunambithekeni kwegesi yemvelo ngesisombululo se-amine.
Ukulawula ukuhlushwa kwe-MDEA okuqondile kubalulekile ekwenzeni ngcono izinqubo zokushukela ama-amine ezitshalweni zokucubungula igesi yemvelo, ezitshalweni ze-petrochemical, ezitshalweni zokuthuthukisa i-biogas, kanye nasezitshalweni zokukhiqiza i-hydrogen. Ngokubhekana nezinselele ezifana nokulinganisa okungalingani, ukusetshenziswa kwamandla aphezulu, amamitha okuhlushwa e-MDEA anika amandla amabhizinisi ukufeza ukusebenza kahle, ukunciphisa izindleko, kanye nokusimama.
