Incazelo Yemikhiqizo
Isistimu yokukhipha igesi ye-hydrogen sulfide (eyaziwa nangokuthi iyunithi yokuhlanza ye-H₂S) iyisethi yesisetshenziswa esihlanganisa ukwelapha kusengaphambili, ukuhlanzwa, kanye-nokwelashwa{0}}kwangemuva.
Umgomo wayo oyinhloko uyahlukahluka ngomzila wezobuchwepheshe: ukumuncwa kwamakhemikhali kusebenzisa izixazululo ze-alkaline (isb, i-sodium hydroxide, i-amine) ukuze isabele nge-H₂S; ukukhangiswa ngokomzimba kuncike kuma-adsorbents (isb, ikhabhoni ecushiwe, izisefo zamamolekyuli) ukuze licuphe i-H₂S; ukususwa kwezinto eziphilayo kusebenzisa ama-microorganisms ukwenza i-H₂S ibe yizinto ezingenabungozi.
Ingakwazi ukulawula ngokuzinzile okuqukethwe kwe-H₂S kugesi ehlanzekile ukuze ihlangabezane namazinga kazwelonke (isb., i-GB 18918 yamanzi angcolile{3}}engenagesi, i-GB 17820 yegesi yemvelo) futhi iyisiqinisekiso esiyinhloko sokukhiqiza okuphephile kwezimboni nokuvikelwa kwemvelo.
Isimiso sokusebenza
Inqubo yokusebenza yokususwa kweHydrogen Sulfide (ukuthatha umzila ovamile "wokumuncwa kwangaphambili + ukumuncwa kwamakhemikhali + -wokwelapha" njengesibonelo) ingafingqwa njengezinyathelo ezinhlanu eziyinhloko: ukugaywa kusengaphambili kwegesi → ukumuncwa kwamakhemikhali → ukusakazwa kwesixazululo → ukwelashwa kwesisombululo esichithiwe → ukuphuma kwegesi ehlanziwe
Ukwelashwa kwangaphambili kwegesi:I-H₂S-equkethe igesi kuqala ingena esigubhuni nesihlungi ukuze ikhiphe amaconsi awuketshezi (amanzi, uwoyela) kanye nezinhlayiya eziqinile (uthuli, ukungcola) ezinosayizi wezinhlayiyana Omkhulu noma olingana no-5 μm. Lokhu kuvimbela ukuvaleka kwemibhoshongo/amapayipi okumuncwa futhi kugwema ukwehlisa umsebenzi wezimunyisi/izixazululo.
Ukumuncwa kwamakhemikhali:Igesi efakwe ngaphambilini igeleza iye phezulu isuka phansi embhoshongweni, kuyilapho i-alkaline engu-5-15% yokumunca i-alkaline (isb., isixazululo se-sodium hydroxide yegesi ephansi-ye-CO₂, isixazululo se-amine se-MDEA segesi ye-CO₂ ephezulu) sifuthwa siye phansi sisuka phezulu. Embhedeni opakishiwe (ogcwele ukupakishwa okuhlelekile njengamandandatho e-pall), igesi noketshezi kufinyelela ukuthintana okugcwele: I-H₂S isabela ngesimunyini (isb, H₂S {{8}NaOH → Na₂S + 2H₂O) ukuze kwakhe usawoti oncibilikayo, othwalwa umbhoshongo phansi ngesixazululo.
Ukujikeleza kwesixazululo:Isixazululo esimuncayo ngemva kokumunca i-H₂S siqoqwa ku-sump engezansi yombhoshongo, bese siphonswa kusishintshi sokushisa ukuze siphole (ukulawula izinga lokushisa ku-30-40℃ukuze kugcinwe ukusebenza kahle kokumuncwa), futhi ekugcineni kusetshenziswe kabusha emuva phezulu kombhoshongo. Ingxenye encane "yesixazululo esichithiwe" (encishisiwe ukugcwala kwe-alkali) ikhishwa ngokuqhubekayo ukuze kugwenywe ukunqwabelana kukasawoti.
Ukwelashwa kwesixazululo esichithiwe:Isixazululo esichithiwe esichithiwe (esiqukethe i-sodium sulfide/ammonium sulfide) sithunyelwa ethangini le-neutralization, lapho siphathwa khona ngama-oxidants (isb., i-hydrogen peroxide) ukuze kuguqulwe ama-sulfide abe yisulfure engenangozi noma i-sulfate, bese ikhishwa ngemva kokuhlangabezana nezindinganiso zamanzi angcolile. Kumasistimu-esikali esikhulu, isixazululo singenziwa kabusha (isb., ukukhumula isixazululo se-amine) ukuze kusetshenziswe kabusha okumunca.
Okukhipha igesi ehlanzekile:I-H₂S-iphuma igesi ekhishiwe phezulu kombhoshongo wokumuncwa, idlula kusinqamuli senkungu ukuze ikhiphe amaconsi oketshezi afakiwe (i-residual absorbent), bese ithuthelwa ezinqubweni eziya ezansi nomfula (isb., ipayipi legesi yemvelo, isistimu yokuvutha) noma ikhishwe ngemva kokuhlangabezana nezindinganiso zemvelo.
