Kutsuka kwa amine, komwe kumadziwikanso kuti amine sweetening, ndi njira yofunika kwambiri yogwiritsira ntchito mankhwala kuti igwire mpweya wa asidi monga CO2 kapena H2S, makamaka m'mafakitale monga mafakitale opangira gasi lachilengedwe, mafakitale opanga petrochemical, mafakitale okonzanso biogas, ndi mafakitale opanga haidrojeni. Njira yotsuka kwa amine ndiyofunikira kwambiri pochotsa mpweya wa asidi monga CO2 kapena H2S m'mitsinje ya mpweya kuti tipewe dzimbiri poyendetsa motsatira zofunikira za mapaipi.
Chifukwa Chake Kukhazikika kwa MDEA N'kofunika mu Amine Scrubbing
MethylDiEthanolAmine (MDEA) ndi amine yomwe imagwiritsidwa ntchito kwambiri mu makina otsukira a amine chifukwa cha luso lake pochotsa CO2 kapena H2S mwachisawawa. Kusunga kuchuluka koyenera kwa mankhwala a MDEA ndikofunikira pazifukwa zingapo:
- Kugwiritsa Ntchito Bwino Njira:Kuchuluka kwa MDEA komwe kumakhala bwino kumatsimikizira kuyamwa kwa mpweya wa asidi wambiri, kuchepetsa kugwiritsa ntchito mphamvu mu chomera chotsekemera cha mpweya wa amine.
- Kuchepetsa Mtengo: Kuwongolera molondola kumachepetsa kugwiritsa ntchito mopitirira muyeso kwa amine, kuchepetsa ndalama zogwirira ntchito komanso kuchepetsa kuwononga zinthu.
- Kutsatira Malamulo: Kuwunika kolondola kumaonetsetsa kuti miyezo ya chilengedwe ikutsatira malamulo mwa kuchotsa CO2 kapena H2S moyenera, mogwirizana ndi zolinga zokhazikika.
Mavuto Okhudza Kulamulira Kukhazikika kwa MDEA
Kuwunika kuchuluka kwa amine mkati mwa MDEA kumakumana ndi zovuta monga kuyeza kosasinthasintha, komwe kungayambitse dzimbiri paipi ndi zida ngati mpweya wa asidi CO2 kapena H2S sunagwidwe bwino. Kuphatikiza apo, kuchuluka kwa amine kolakwika kumatha kuwonjezera kugwiritsa ntchito mphamvu munthawi yokonzanso zinthu, zomwe zimakhudza magwiridwe antchito.
Mayankho a Lonnmeter a Inline MDEA Concentration Monitoring
Mainjiniya a lonnmeter apereka njira zothandiza zothandizira zomera zotere kuti ziwunikire bwino kuchuluka kwa mpweya wa MDEA mwa kuphatikiza mayunitsi otsekemera mpweya wachilengedwe ndi mita yowunikira ya ultrasonic. Imawerengera liwiro la sonic malinga ndi nthawi yotumizira mu media yoyesedwa, kenako ndikuzindikira kuchuluka kwa mayankho a amine m'mitsinje.
Kagwiridwe ka ntchito ka makina sikadzawonongeka pakapita nthawi chifukwa cha zinthu zosasuntha. Sensa imawerengera liwiro la mawu pogwiritsa ntchito mtunda wokhazikika pakati pa chotumizira cha ultrasonic ndi cholandirira. Njira yoyezera siili ndi malire chifukwa cha mphamvu yamagetsi, mtundu, ndi kuwonekera bwino kwa zinthuzo pamene ikusunga kudalirika ndi kulondola koyenera mpaka 0.05%.
Zowunikira kuchuluka kwa amine zimapangidwa kuti zithetse mavuto a kuwongolera kuchuluka kwa MDEA, zomwe zimathandiza kuwunika deta nthawi yeniyeni ndikuchepetsa kuchuluka kwa kukonza ndi nthawi yotseka zida.
Zogulitsa Zovomerezeka
Ubwino wa Zosensa za Njira za Lonnmeter
Kulondola Kosayembekezereka
Kulondola kopanda malire kwa mita ya amine ndi 0.05% ~ 0.1%. Kulondola kwapadera kumeneku kumatsimikizira kuwunika kolondola kwa kuchuluka kwa MDEA m'njira monga kutsekemera kwa mpweya wachilengedwe ndi CO2.2kutsuka amine, zomwe zimathandiza kuti mpweya wa asidi monga CO2 ulowe bwino2kapena H2S pamene akuchepetsa kugwiritsa ntchito mphamvu ndi zinyalala za amine.
Kuwunika ndi Kusintha kwa Nthawi Yeniyeni
Kuphatikizika kwake kosalekeza ndi machitidwe a PLC ndi DCS kudzera mu ma protocol wamba monga 4-20mA ndi RS 485 kumathandiza kutumiza deta nthawi yeniyeni, zomwe zimathandiza kusintha njira mwachangu. Izi zimachepetsa kutayika kwa mphamvu chifukwa cha kukonzanso kwambiri, ndikusunga mpaka 15-20% ya ndalama zamagetsi pakuwonjezera shuga wachilengedwe pogwiritsa ntchito yankho la amine.
Kuchepetsa Mtengo
Mwa kukonza bwino kulamulira kwa MDEA, masensawa amachepetsa kugwiritsa ntchito mphamvu, amachepetsa kutaya kwa amine, amachepetsa ndalama zokonzera, komanso amaletsa nthawi yotsika mtengo yogwira ntchito, zomwe zimapangitsa kuti zikhale zosintha kwambiri mafakitale okonzera mpweya wa amine omwe amakonza mpweya wachilengedwe wowawasa kuti unyamulidwe bwino m'mapaipi pomwe akupewa ndalama zokhudzana ndi dzimbiri.
Kuwunika molondola kumaletsa kuwonongeka kwa amine kuti isagwiritsidwe ntchito molakwika, zomwe zimapangitsa kuti ntchito ya MDEA ikhale yolimba. Izi zimachepetsa kuchuluka kwa mankhwala omwe amalowa m'malo mwake, zomwe zimachepetsa ndalama zogulira mankhwala ndi 5-10% pachaka.
Mafunso Ofunsidwa Kawirikawiri
Kodi Amine Scrubbing ndi chiyani ndipo chifukwa chiyani MDEA imagwiritsidwa ntchito?
Kutsuka kwa amine ndi njira yomwe imagwiritsidwa ntchito m'mafakitale otsekemera a amine kuti achotse mpweya wa acidic monga CO2 kapena H2S m'mitsinje ya mpweya. MDEA imakondedwa chifukwa cha kusankha kwake kwakukulu kwa CO2 ndi H2S, kufunikira kochepa kwa mphamvu kuti ibwezeretsedwe, komanso kuchepetsa kuwonongeka.
Kodi Ubwino wa Kuwunika Kukhazikika kwa MDEA mu Nthawi Yeniyeni Ndi Wotani?
Kuwunika nthawi yeniyeni pogwiritsa ntchito MDEA concentration measurements kumapereka deta mwachangu pa kuchuluka kwa amine, zomwe zimathandiza kusintha mwachangu kuti ntchito igwire bwino ntchito. Ubwino wake ndi monga kuchepetsa kugwiritsa ntchito mphamvu, kuchepetsa kugwiritsa ntchito amine, nthawi yayitali ya zida, komanso kutsatira zolinga zokhazikika pakuchepetsa shuga wachilengedwe pogwiritsa ntchito njira ya amine.
Kuwongolera kuchuluka kwa MDEA mkati mwake ndikofunikira kwambiri pakukonza njira zotsekemera za amine m'mafakitale opangira gasi wachilengedwe, mafakitale opanga petrochemical, mafakitale okonzanso biogas, ndi mafakitale opanga haidrojeni. Mwa kuthana ndi mavuto monga miyeso yosasinthasintha, kugwiritsa ntchito mphamvu zambiri, mita yoyezera kuchuluka kwa MDEA imapatsa mabizinesi mphamvu zogwirira ntchito bwino, kuchepetsa ndalama, komanso kukhazikika.
