1. Indlela yokunciphisa amalahle ahlutshiwe, i-mirabilite namalahle ahlutshiwe axutshwe ngesilinganiso se-100: (21-22.5) (isilinganiso sesisindo) futhi i-calcined futhi iyancipha ekushiseni okuphezulu kwe-800-1100 ° C, futhi umphumela upholile futhi ufudumala incibilikiswa oketshezini olune-lye ewuketshezi, ngemva kokumela ukucaciswa, isixazululo se-lye esigxilile esiphezulu siyagxiliswa ukuze kutholakale i-sodium sulfide eqinile. Ithebhulethi (noma i-granule) umkhiqizo we-sodium sulfide itholakala ngethangi lokudlulisa, ithebhulethi (noma i-granulation)
I-Chemical reaction equation: Na2SO4+2C→Na2S+2CO2

2.Indlela yokumunca: 380-420 g/L sodium hydroxide solution isetshenziselwa ukumunca igesi engcolile equkethe i-H2S>85% i-hydrogen sulfide, futhi umkhiqizo otholiwe uyahwamuka futhi ugxiliswe ukuze kutholwe umkhiqizo oqediwe we-sodium sulfide.
Isibalo sokusabela kwamakhemikhali: H2S+2NaOH→Na2S+2H2O

3. Indlela ye-Barium sulfide, i-sodium sulfide ingatholakala njengomkhiqizo lapho i-sodium sulfate ne-barium sulfide isetshenziselwa ukusabela kwe-metathesis ukuze kulungiswe i-barium sulfate ene-precipitated. Lokho
I-Chemical reaction equation: BaS+Na2SO4→Na2S+BaSO4↓

4. Indlela yokunciphisa igesi, phambi kwe-iron catalyst, i-hydrogen (noma i-carbon monoxide, igesi yomkhiqizi, igesi ye-methane) iphendulwa nge-sodium sulfate esithandweni esibilayo, kanye nekhwalithi ephezulu ye-anhydrous granular sodium sulfide (equkethe i-Na2S 95%) ingakwazi. kutholwe. ~97%).
I-Chemical reaction equation:
I-Na2SO4+4CO→Na2S+4CO2
I-Na2SO4+4H2→Na2S+4H2O

I-5.Indlela yokukhiqiza, indlela yokucwenga isebenzisa isisombululo se-sodium sulfide ene-concentration ye-4% by-product ohlelweni lokukhiqiza i-precipitated barium sulfate njengento eluhlaza. Ngemva kokuyimpompa ku-evaporator enemiphumela emibili ukuze ihwamuke ibe ngu-23%, ingena ethangini elinyakazayo ukuze ikhiphe insimbi. , Ngemva kokwelashwa kokukhishwa kwekhabhoni, i-lye iphonswa ku-evaporator (eyenziwe ngezinto ezihlanzekile ze-nickel) ukuze ihwamuke i-lye ukuze ifinyelele ekugxilweni, bese ithunyelwa emshinini wethebhulethi wohlobo lokupholisa amanzi esigubhu.

Ifektri yethu isebenzisa izindlela ezimbili, indlela yokunciphisa amalahle egayiwe kanye nendlela ye-barium sulfide, ukukhiqiza ama-flakes abomvu e-sodium sulfide nama-yellow flakes.
