1. Habka dhimista dhuxusha la jeexjeexay, mirabilite iyo dhuxusha la tumay ayaa lagu qasi karaa saamiga 100: (21-22.5) (miisaanka miisaanka) iyo calcined oo la dhimay heerkul sare oo 800-1100 ° C ah, natiijada waa la qaboojiyey iyo kuleyl. ku milmay dareere leh lye dilution , ka dib markaad u istaagto caddaynta, xalalka sare ee liinta ayaa xoogga saaray si loo helo sodium sulfide adag. Kiniinka (ama granule) badeecada sodium sulfide waxaa lagu helaa haanta wareejinta, tableting (ama granulation)
Isla'egta falcelinta kiimikada: Na2SO4+2C→Na2S+2CO2

2. Habka nuugista: 380-420 g / L sodium hydroxide waxaa loo isticmaalaa in lagu nuugo gaaska qashinka ah ee ay ku jiraan H2S> 85% hydrogen sulfide, iyo alaabta la helay ayaa la uumi-baxa oo xoogga saaray si loo helo soodhiyam sulfide dhammays tiran.
Isla'egta falcelinta kiimikada: H2S+2NaOH→Na2S+2H2O

3. Habka Barium sulfide, sodium sulfide waxaa loo heli karaa sida wax soo saarka marka sodium sulfate iyo barium sulfide loo isticmaalo falcelinta metathesis si loogu diyaariyo barium sulfate. Taasi
Isla'egta falcelinta kiimikada: BaS+Na2SO4→Na2S+BaSO4↓

4. Habka dhimista gaasta, joogitaanka birta birta, hydrogen (ama carbon monoxide, gaaska soo saaraha, gaaska methane) waxaa lagu falceliyaa sodium sulfate ee foornada karkarinaysa, iyo tayada sare ee anhydrous granular sodium sulfide (oo ka kooban Na2S 95%). la helo. ~97%)
Isla'egta falcelinta kiimikada:
Na2SO4+4CO→Na2S+4CO2
Na2SO4+4H2→Na2S+4H2O

Habka wax-soo-saarka, habka sifaynta wuxuu isticmaalaa xal sodium sulfide ah oo leh qiyaasta qiyaastii 4% by-product ee habka soo saarista barium sulfate ee degdega ah sida alaabta ceeriin. Ka dib markii ay ku shubto uumi-saamayn laba-laab leh si ay u uumi-baxdo 23%, waxay gashaa haanta wax-karsiga si ay uga saarto birta. , Ka dib daawaynta ka saarista kaarboonka, lye waxaa lagu shubaa uumiga (oo laga sameeyay walxo nikkel saafi ah) si ay u uumi-baxdo lye si ay u gaadho fiirsashada, waxaana loo diraa durbaanka biyaha qaboojinta mashiinka kiniiniga nooca.

Warshadeenu waxay isticmaashaa laba hab, habka dhimista dhuxusha la miiray iyo habka barium sulfide, si ay u soo saarto jajabyada cas ee sodium sulfide iyo jajab jaalaha ah.
