High Quality China Natural Gasi Desulfurization Unit Opanga - Mchira mpweya mankhwala skid - Rongteng

Kufotokozera

Natural mpweya mchira mpweya mankhwala skid zimagwiritsa ntchito polimbana ndi mchira mpweya wa sulfure kuchira chipangizo, komanso zinyalala mpweya wa madzi sulfure dziwe ndi TEG zinyalala mpweya wa kuchepa madzi m`thupi chipangizo sulfure kuchira chipangizo.
Mapangidwe ndi mphamvu yopangira skid amafanana ndi chipangizo chobwezeretsa sulfure ndi chipangizo chotsitsa madzi m'thupi.

Natural mpweya mchira mpweya mankhwala skid akhoza kugawidwa m'magulu anayi.

1. Njira yochepetsera ndi kuyamwa
Mfundo ya kuchepetsa ndi mayamwidwe ndondomeko ndi kuti mpweya mchira ndi hydrogenated, ndi sulfure munali zigawo zikuluzikulu mu mpweya mchira kuchepetsedwa kukhala H2S, kwaiye H2S ndi kusankha odzipereka ndi njira amine, ndipo potsiriza kubadwanso kapena mpweya wotengedwa kulowa Claus unit kwa kuzungulira anachita. Njira ya Hydrogenation ili ndi ndalama zambiri komanso mtengo wogwirira ntchito, koma imagwiritsidwa ntchito kwambiri m'maiko ndi madera omwe ali ndi zofunikira zoteteza chilengedwe chifukwa imatha kupeza zokolola zambiri za sulfure, monga zoposa 99.8%.

2. Njira mayamwidwe okosijeni
Oxidation mayamwidwe njira ndi njira kuti choyamba oxidize sulfide mu mchira mpweya kuti SO2, ndiye kuyamwa SO2 ndi njira (kapena zosungunulira), ndipo potsiriza achire mu mawonekedwe a sulfate, sulfide ndi SO2.
Pali njira zambiri zamtunduwu, zambiri zomwe zimagwiritsidwa ntchito pochotsa mpweya wa flue kapena kuchiza mpweya wa mchira kuchokera ku smelters ndi zomera za sulfuric acid, ndipo njira ya Wellman Lord imagwiritsidwa ntchito pochiza gasi la Claus.

3. Low kutentha Claus ndondomeko
Ukadaulo wochepa wa kutentha wa Claus umadziwika ndi momwe Claus amachitira pansi pa mame a sulfure, motero amatchedwanso njira yobwezeretsa mame a sulfure. Claus reaction ndi amphamvu exothermic reaction process. Choncho, kutentha otsika kumathandiza kuti kusintha kwa mgwirizano kwa njira ya sulfure m'badwo, amene akhoza kusintha sulfure kuchira. Malinga ndi ubale womwe ulipo pakati pa zochita za Claus ndi unit, kutentha kwapang'onopang'ono kwa Claus kumatha kugawidwa munjira yodziyimira payokha yotsika kutentha kwa Claus ndikuphatikiza kutsika kwa kutentha kwa Claus.

4. Madzi gawo mwachindunji makutidwe ndi okosijeni ndondomeko
Liquid phase direct oxidation process ndi mtundu waukadaulo waukadaulo womwe umatulutsa mwachindunji H2S kupita ku elemental sulfure. Mfundo ya ndondomekoyi ndi kuyamwa H2S mu mpweya mchira ndi njira desulfurization, ndiyeno oxidize kuti apange elemental sulfure.

Zosintha zaukadaulo

1, SO2 ≤ 400mg/Nm3 (youma maziko, 3vol% O2)
2, Nthawi yopanga pachaka maola 8000
3, kusinthasintha kwa ntchito 50% ~ 120%
