Mawu Oyamba
MDEA Natural gas desulphurization (desulfurization) skid, yotchedwanso MDEA sweeting skid and Natural gas desulfurization unit, ndi chida chofunikira kwambiri pakuyeretsa gasi kapena kukonza gasi.
MDEA gasi desulfurization wagawo nthawi zonse anatengera pamene mpweya sulfure wa chakudya mpweya ndi mkulu , ndi kusankha kuchotsa H2S imafunika kuti mupeze mpweya wa asidi woyenera kukonzedwa kwa zomera za Claus, ndi zina zomwe zingasankhidwe kuchotsa H2 S; Pochotsa H2S ndikuchotsa kuchuluka kwa CO2, MDEA ingagwiritsidwe ntchito ngati njira yosakanikirana ya amine;
Pakali pano, umisiri waukulu desulfurization ntchito kupanga mafakitale kunyumba ndi kunja ndi: youma (thupi) desulfurization, kwachilengedwenso desulfurization ndi chonyowa desulfurization.
Kunyowa desulfurization kumaphatikizapo njira ya mayamwidwe ndi njira yonyowa ya okosijeni. Njira yoyamwitsa mankhwala, yoimiridwa ndi mayamwidwe a mowa amine, yakhala ikugwiritsidwa ntchito kwambiri m'makampani. Hydrogen sulfide mu gasi amasamutsidwa ku gawo lamadzimadzi kuti ayeretse gasi.
Tekinoloje ya desulfurization
Ukadaulo wa biological desulfurization, mu mkhalidwe wa okosijeni yaying'ono, ukhoza kusintha hydrogen sulfide kukhala sulfure yoyambira, koma ukadaulo wa biological desulfurization siwokhwima pakali pano.
Dry desulfurization luso zikuphatikizapo chitsulo okusayidi njira, adamulowetsa mpweya njira, maselo sieve njira, ayoni kuwombola njira, nembanemba kulekana njira, biochemical njira, etc. pakali pano, youma PSA luso ndi ambiri ankagwiritsa ntchito yaing'ono gasi desulfurization mankhwala mu makampani. , yomwe imayang'aniridwa ndi makompyuta, imagwira ntchito yokha, komanso kuchotsa zowonongeka zowonongeka, kuti athe kuzindikira ntchito yotetezeka kwa nthawi yaitali.
njira za desulfurization
Amorphous iron hydroxide (youma ndondomeko). Mawonekedwe: ili ndi mikhalidwe yolondola kwambiri ya desulfurization, kuchuluka kwa sulfure, mphamvu yabwino komanso osayang'aniridwa. Amagwiritsidwa ntchito kwambiri pochotsa hydrogen sulfide mu gasi, gasi wopangidwa, biogas, gasi wamalasha, methane ya malasha ndi zida zosiyanasiyana za sulfure; The amorphous hydroxyl oxidation desulfurization ndi zochita desulfurization, amene sangathe kulamulira desulfurization kuya. Ndi njira yabwino desulfurization. Ndi machulukitsidwe wa desulfurizer ndi malowedwe a desulfurization nsanja, zotsatira desulfurization adzachepa kwambiri, ndi zili hydrogen sulfide mu oyeretsedwa gasi adzauka kwambiri, choncho m`pofunika m`malo desulfurizer mu nthawi.
