1. Pulverized kwal rage Hanyar, mirabilite da pulverized kwal suna gauraye a cikin wani rabo na 100: (21-22.5) (nauyin rabo) da calcined da rage a wani babban zafin jiki na 800-1100 ° C, da kuma sakamakon da aka sanyaya da thermally. narkar da cikin ruwa tare da dilute lye , bayan tsayawa don bayani, babban abin da aka mayar da hankali ga lye yana mayar da hankali don samun m sodium sulfide. Ana samun samfurin (ko granule) sodium sulfide samfurin ta hanyar canja wurin tanki, tableting (ko granulation)
Ma'aunin halayen sinadaran: Na2SO4+2C→Na2S+2CO2

2.Absorption Hanyar: 380-420 g / L sodium hydroxide bayani da ake amfani da sharar iskar gas dauke da H2S> 85% hydrogen sulfide, da kuma samu samfurin da aka evaporated da mayar da hankali don samun sodium sulfide gama samfurin.
Ma'aunin halayen sinadaran: H2S+2NaOH→Na2S+2H2O

3. Hanyar Barium sulfide, ana iya samun sodium sulfide a matsayin samfurin samfurin lokacin da ake amfani da sodium sulfate da barium sulfide don maganin metathesis don shirya barium sulfate. Wannan
Ma'aunin halayen sinadaran: BaS+Na2SO4→Na2S+BaSO4↓

4. Hanyar rage iskar gas, a gaban mai kara kuzari, hydrogen (ko carbon monoxide, iskar gas, methane gas) ana amsawa tare da sodium sulfate a cikin tanderun tanderun, da ingantaccen granular granular sodium sulfide (dauke da Na2S 95%) na iya a samu. ~97%).
Daidaiton amsawar sinadarai:
Na2SO4+4CO →Na2S+4CO2
Na2SO4+4H2→Na2S+4H2O

Hanyar 5.Production, hanyar tsaftacewa yana amfani da maganin sodium sulfide tare da maida hankali na kimanin 4% ta samfurin a cikin aiwatar da samar da barium sulfate precipitated a matsayin albarkatun kasa. Bayan an zuga shi a cikin injin da zai ƙafe zuwa kashi 23%, yana shiga cikin tanki mai motsawa don cire baƙin ƙarfe. , Bayan maganin cirewar carbon, ana zubar da lemun tsami a cikin evaporator (wanda aka yi da kayan nickel mai tsabta) don kawar da lye don isa ga maida hankali, kuma a aika zuwa na'ura mai sanyaya ruwa na drum.

Ma'aikatar mu tana amfani da hanyoyi guda biyu, hanyar rage kwal da barium sulfide, don samar da jan flakes na sodium sulfide da launin rawaya.
