Kutsuka kwa amine, komwe kumadziwikanso kuti kutsekemera kwa amine, ndi njira yopangira mankhwala kuti igwire mpweya wa asidi monga CO2 kapena H2S, makamaka m'mafakitale monga mafakitale opangira gasi, zomera za petrochemical, zomera zopangira biogas, ndi zomera zopanga haidrojeni. Njira yotsuka amine ndiyofunikira pakuchotsa mpweya wa acidic ngati CO2 kapena H2S kuchokera ku mitsinje ya gasi kuti zisawonongeke pamayendedwe opitilira malinga ndi zofunikira zamapaipi.
Chifukwa Chake Kukhazikika kwa MDEA Kumafunika Pakupukuta Amine
MethylDiEthanolAmine (MDEA) ndi amine yomwe imagwiritsidwa ntchito kwambiri m'makina otsuka amine chifukwa chakuchita bwino pakuchotsa CO2 kapena H2S. Kusunga yankho lolondola la MDEA ndikofunikira pazifukwa zingapo:
- Kuchita Mwachangu:Kukhazikika koyenera kwa MDEA kumatsimikizira kuyamwa kwakukulu kwa mpweya wa acidic, kuchepetsa kugwiritsa ntchito mphamvu mumafuta otsekemera a amine.
- Kuchepetsa Mtengo: Kuwongolera molondola kumachepetsa kugwiritsidwa ntchito mopitirira muyeso kwa amine, kutsitsa mtengo wogwirira ntchito komanso kuchepetsa zinyalala.
- Kutsata Malamulo: Kuyang'anira kolondola kumatsimikizira kutsata miyezo ya chilengedwe pochotsa bwino CO2 kapena H2S, kugwirizanitsa ndi zolinga zokhazikika.
Zovuta Pakuwongolera Kukhazikika kwa MDEA
Kuwunika kwa inline kwa MDEA pakutsuka kwa amine kumakumana ndi zovuta monga miyeso yosagwirizana, zomwe zingayambitse kuwonongeka kwa mapaipi ndi zida ngati mpweya wa asidi CO2 kapena H2S utalephera kugwidwa bwino. Kuphatikiza apo, kuyika kwa amine molakwika kumatha kukulitsa kugwiritsa ntchito mphamvu pakukonzanso, zomwe zimakhudza magwiridwe antchito.
Mayankho a Lonnmeter a Inline MDEA Concentration Monitoring
Akatswiri a lonnmeter apereka njira zothandiza zothandizira zomera zomwe zimakonda kuwunikira molondola ndende ya MDEA mwa kuphatikiza mayunitsi okometsera a gasi ndi akupanga ndende mita. Imawerengera liwiro la sonic molingana ndi nthawi yopatsira mu media yoyezera, kenako ndikuyika mayankho a amine mumitsinje.
Kuchita kwamakina sikudzawonongeka ndi nthawi yopanda magawo osuntha. Sensa imawerengera kuthamanga kwa sonic ndi mtunda wokhazikika pakati pa ultrasonic transmitter ndi wolandila. Njira yoyezera ndiyosayendetsedwa ndi ma conductivity, mtundu ndi kuwonekera kwa media pomwe kusunga kudalirika koyenera komanso kulondola mpaka 0.05%.
Zowunikira zowunikira za amine zidapangidwa kuti zithandizire kuthana ndi zovuta za inline MDEA control control, kupangitsa kuwunika kwa data munthawi yeniyeni ndikuchepetsa pafupipafupi kukonza ndi kutseka kwa zida.

Ubwino wa Lonnmeter Process Sensors
Kulondola Mosayembekezereka
The amine ndende mita zosayerekezeka kulondola 0.05% ~ 0.1%. Kulondola kwapaderaku kumatsimikizira kuwunika kolondola kwa ndende ya MDEA munjira monga kutsekemera kwa gasi ndi CO.2kupukuta kwa amine, kumathandizira kuyamwa bwino kwa mpweya wa acidic ngati CO2kapena H2S pamene kuchepetsa kugwiritsa ntchito mphamvu ndi kuwononga amine.
Kuwunika ndi Kusintha Kwanthawi Yeniyeni
Kuphatikizika kwake kosasunthika ndi machitidwe a PLC ndi DCS kudzera pamaprotocol monga 4-20mA ndi RS 485 kumathandizira kutumiza kwa data munthawi yeniyeni, kulola kusintha kwanthawi yomweyo. Izi zimachepetsa kuwononga mphamvu kuchokera pakukonzanso, kupulumutsa mpaka 15-20% pamitengo yamagetsi mumafuta achilengedwe otsekemera ndi yankho la amine.
Kuchepetsa Mtengo
Mwa kukhathamiritsa kuwongolera kuwongolera kwa njira ya MDEA, masensa awa amachepetsa kugwiritsa ntchito mphamvu, amachepetsa kuwonongeka kwa amine, kuchepetsa mtengo wokonza, ndikuletsa kutsika kwamtengo wapatali, kuwapangitsa kukhala osintha makina azomera zokometsera gasi wa amine kukonzekera gasi wowawasa kuti ayendetse mapaipi otetezeka ndikupewa kuwononga ndalama zokhudzana ndi dzimbiri.
Kuwunika kolondola kumalepheretsa kuwonongeka kwa amine kuti asamangidwe molakwika, kukulitsa moyo wogwiritsidwa ntchito wa mayankho a MDEA. Izi zimachepetsa kubweza pafupipafupi, kutsitsa mtengo wogula mankhwala ndi 5-10% pachaka.
FAQs
Kodi Amine Scrubbing ndi Chifukwa Chiyani MDEA Imagwiritsidwa Ntchito?
Kukolopa kwa Amine ndi njira yomwe imagwiritsidwa ntchito muzomera zokometsera gasi wa amine kuchotsa mipweya ya acidic ngati CO2 kapena H2S kumitsinje yamafuta. MDEA imakondedwa chifukwa cha kusankha kwake kwakukulu kwa CO2 ndi H2S, kutsika kwamphamvu kwamphamvu kuti ipangidwenso, komanso kuchepa kwa dzimbiri.
Kodi Ubwino Wotani Panthawi Yeniyeni Yoyang'aniridwa ndi MDEA Concentration Monitoring?
Kuwunika kwanthawi yeniyeni ndi ma metres owerengera a MDEA kumapereka chidziwitso chaposachedwa pamilingo ya amine, zomwe zimathandizira kusintha mwachangu kuti ntchitoyo isagwire bwino. Ubwino wake ndi monga kuchepetsa kugwiritsa ntchito mphamvu, kutsika kwa ma amine, kugwiritsa ntchito nthawi yayitali kwa zida, komanso kutsatira zolinga zokhazikika pakutsekemera kwa gasi wopangidwa ndi amine solution.
Kuwongolera inline ndende ya MDEA ndikofunikira pakukhathamiritsa njira zokometsera amine m'mafakitale opangira gasi, malo opangira mafuta, malo opangira ma biogas, ndi mafakitale opanga ma haidrojeni. Pothana ndi zovuta monga miyeso yosagwirizana, kugwiritsa ntchito mphamvu kwambiri, ma metres okhazikika a MDEA amathandizira mabizinesi kuti akwaniritse bwino ntchito, kuchepetsa mtengo, komanso kukhazikika.
With real-time data, robust sensor designs, and strategic implementation, these instruments transform the amine gas sweetening process, ensuring compliance and maximizing performance.
