amakuru

1. Uburyo bwo kugabanya amakara ya pulverized, mirabilite hamwe namakara bivangwa bivanze mukigereranyo cya 100: (21-22.5) (igipimo cyibiro) hanyuma ubarwa kandi ugabanuka kubushyuhe bwo hejuru bwa 800-1100 ° C, hanyuma ibisubizo bikonjeshwa hamwe nubushyuhe. gushonga mumazi hamwe na lye ya dilute, nyuma yo guhagarara kugirango bisobanurwe, igisubizo cyo hejuru cya lye cyibanze cyane kugirango kibone sodium sulfide ikomeye.Tablet (cyangwa granule) ibicuruzwa bya sodium sulfide biboneka binyuze muri transfert, tableti (cyangwa granulation)
Ikigereranyo cya reaction ya chimique: Na2SO4 + 2C → Na2S + 2CO2

2.Uburyo bukoreshwa: 380-420 g / L sodium hydroxide yumuti ikoreshwa mugukuramo imyanda irimo H2S> 85% hydrogène sulfide, kandi ibicuruzwa byabonetse bigahumeka kandi bigahunikwa kugirango ubone sodium sulfide yuzuye.
Ikigereranyo cya reaction ya chimique: H2S + 2NaOH → Na2S + 2H2O

3. Uburyo bwa Barium sulfide, sodium sulfide irashobora kuboneka nkibicuruzwa mugihe sodium sulfate na barium sulfide ikoreshwa muburyo bwa metathesis kugirango bategure barium sulfate yaguye.Ibyo
Ikigereranyo cya reaction ya chimique: BaS + Na2SO4 → Na2S + BaSO4 ↓

4. Uburyo bwo kugabanya gazi, imbere ya catalizator yicyuma, hydrogène (cyangwa monoxide ya karubone, gaze itanga gaze, gaze metani) ikorwa na sodium sulfate mu itanura ritetse, hamwe na sodium sulfide ya anhydrous nziza cyane (irimo Na2S 95%) irashobora kuboneka.~ 97%).
Ikigereranyo cya reaction ya chimique:
Na2SO4 + 4CO → Na2S + 4CO2
Na2SO4 + 4H2 → Na2S + 4H2O

5.Uburyo bwo kubyara, uburyo bwo gutunganya bukoresha sodium sulfide yumuti hamwe nibice 4% byibicuruzwa mugihe cyo kubyara barium sulfate yimvura nkibikoresho fatizo.Nyuma yo kuyijugunya mumashanyarazi abiri kugirango ihindurwe kugeza 23%, yinjira mukigega gikurura ibyuma., Nyuma yo kuvanaho karubone, lye isunikwa mumashanyarazi (ikozwe mubintu bya nikel isukuye) kugirango ihindurwe kugirango igere kuri concentration, hanyuma yoherezwa muma mashini ya tablet yo gukonjesha amazi.

Uruganda rwacu rukoresha uburyo bubiri, uburyo bwo kugabanya amakara hamwe nuburyo bwa barium sulfide, kugirango butange sodium sulfide itukura na flake yumuhondo.
