1. Indlela yokunciphisa amalahle ahlanjululweyo, i-mirabilite kunye namalahle ahlanjululweyo axutywe kumlinganiselo we-100: (21-22.5) (umlinganiselo wobunzima) kunye ne-calcined kwaye iyancipha kwiqondo lokushisa eliphezulu le-800-1100 ° C, kwaye umphumo upholile kwaye ushushu. inyibilikiswe kulwelo ngelyethi enyibilikayo, emva kokumela ingcaciso, isisombululo selye esixutywe phezulu sigxininiswe ukuze kufumaneke isodiyam sulfide eqinileyo. Ithebhulethi (okanye igranule) imveliso ye-sodium sulfide ifumaneka ngetanki yokudlulisa, ithebhulethi (okanye igranulation)
I-Chemical reaction equation: Na2SO4+2C→Na2S+2CO2

I-2.Indlela yokufunxa: I-380-420 g / L isisombululo se-sodium hydroxide sisetyenziselwa ukufunxa igesi yenkunkuma equkethe i-H2S> i-85% ye-hydrogen sulfide, kwaye imveliso efunyenweyo i-evaporated kwaye igxininiswe ukufumana imveliso ye-sodium sulfide egqityiweyo.
I-Chemical reaction equation: H2S+2NaOH→Na2S+2H2O

3. Indlela ye-Barium sulfide, i-sodium sulfide inokufumaneka njengemveliso xa i-sodium sulfate kunye ne-barium sulfide zisetyenziselwa ukusabela kwe-metathesis ukulungiselela i-precipitated barium sulfate. Oko
I-Chemical reaction equation: BaS+Na2SO4→Na2S+BaSO4↓

4. Indlela yokunciphisa igesi, phambi kwe-iron catalyst, i-hydrogen (okanye i-carbon monoxide, igesi yomvelisi, igesi ye-methane) iphendulwa kunye ne-sodium sulfate kwisithando somlilo esibilayo, kunye ne-high-quality anhydrous granular sodium sulfide (equlethe i-Na2S 95%). kufunyanwa. ~97%).
I-Chemical reaction equation:
Na2SO4+4CO→Na2S+4CO2
Na2SO4+4H2→Na2S+4H2O

I-5.Indlela yokuvelisa, indlela yokucoca isebenzisa isisombululo se-sodium sulfide kunye ne-concentration malunga ne-4% yemveliso kwinkqubo yokuvelisa i-precipitated barium sulfate njengento eluhlaza. Emva kokuyimpompa kwi-evaporator ene-double-effect ukuze ibe ngumphunga ukuya kwi-23%, ingena kwi-tank eshukumisayo ukususa isinyithi. , Emva kokunyanga ukususwa kwekhabhoni, i-lye impontshelwa kwi-evaporator (eyenziwe ngezinto ezicocekileyo ze-nickel) ukuze ikhuphe i-lye ukuze ifikelele kugxininiso, kwaye ithunyelwe kwi-drum yamanzi ohlobo lokupholisa umatshini wethebhulethi.

Umzi-mveliso wethu usebenzisa iindlela ezimbini, indlela yokunciphisa amalahle kunye nendlela ye-barium sulfide, ukuvelisa iiflakes ezibomvu ze-sodium sulfide kunye neeflakes ezityheli.
