High Quality China Desulfurization Equipment Factory - MDEA njira decarburization skid pazida zoyatsira gasi - Rongteng

Kufotokozera

Kutsetsereka kwa gasi wachilengedwe (decarbonization) skid, ndi chida chofunikira pakuyeretsa kapena kuchiza gasi.

Zomwe zili mu mpweya woipa mu mpweya wabwino wa gasi siziyenera kupitirira 3%. Ndipo mpweya woipa m'madzi utatha chitsulocho chimakhala ndi zowonongeka kwambiri. Ngati mtengo wa pH uli womwewo, chiŵerengero cha acidity cha carbon dioxide chimakhalanso chapamwamba, kotero kuti mpweya woipa wa carbon dioxide pazitsulo umakhalanso wapamwamba.

Chifukwa chake, pakufunidwa kwa decarburization ya gasi, ndikofunikira kuti pakhale mphamvu yotenthetsera panthawi ya decarburization, kotero kuti mpweya wachilengedwe pambuyo pa humidification kutentha kwamankhwala sikuli koyenera kutulutsa mpweya wachilengedwe. Komabe, ngati sitiganizira zinthu za decarbonization gasi, koma kutengera njira otsika kutentha kulekana, izo mwachindunji kutsogolera dzuwa decarbonization gasi. Pakadali pano, kugwiritsa ntchito mankhwala achilengedwe a decarbonization kumatha kupanga njira ya mowa ammonia.

Tchati choyenda

Malinga ndi mawonekedwe aukadaulo wa MDEA, njira yosinthira pang'ono ndiyofunikira pakuchotsa mpweya wachilengedwe. Pakati pawo, mpweya wachilengedwe umalowa kwambiri kuchokera pansi, ndikulumikizana ndi njira ya MDEA kuchokera pamwamba mpaka pansi mu absorber, koma njira zambiri za carbon dioxide mu gasi zimachotsedwa. Mpweya wonyowa woyeretsedwa umasiyanitsidwa makamaka ndi nsanja yoyamwitsa ndikukhazikika, kenako ndikusowa madzi. MDEA kuchokera pansi pa nsanja yoyamwitsa imafunikira mphamvu kuti ilowe mu chithandizo cha kutaya madzi m'thupi, ndipo gawo lapamwamba la nsanja yoyamwitsa limalowa mu nsanja. Pambuyo decompression, otengeka mpweya woipa kuthetsedwa ndi kutenthedwa ndi nthunzi pakati pa kusinthika nsanja. Ndi njira iyi yokha yomwe kutentha kwa yankho kungasungidwe. Pambuyo pa yankho la MDEA kuchokera pansi pa nsanjayo litakhazikika, yankho limalowa pamwamba pa kuyamwa, kuti amalize njira yonse yozungulira yankho. Kuonjezera apo, pofuna kuonetsetsa kuti yankho likhoza kubwezeretsedwanso ndikutsukidwanso, 15% ya yankho imafunika kuti ichotsedwe. Pofuna kusunga njira ya decarbonization ya gasi wachilengedwe, dongosololi lidzasinthidwanso kudzera mu njira yothetsera.

Zogwira ntchito

Kuchita bwino kwa decarbonization ndi njira ya MDEA ndi 99%.
Pofuna kuchotsa mpweya woipa (CO2) ku gasi wa chakudya, njira yamadzimadzi yokhala ndi mowa wa amine monga zosungunulira zimakhudzidwa ndi CO2 mu mpweya wa chakudya. Kuchepa kwa gasi komanso kugwiritsa ntchito mphamvu zambiri. Njira ya mowa wa amine itha kugwiritsidwanso ntchito kuchotsa H2S ku gasi wa chakudya.
