1. Nzira yekudzikisa marasha yakaputsika, mirabilite uye marasha akaputirwa anosanganiswa muchiyero che100: (21-22.5) (yeyero yehuremu) uye yakaverengerwa uye yakaderedzwa pakupisa kwakanyanya kwe800-1100 ° C, uye mhedzisiro yacho inotonhorera uye inopisa. yakanyungudutswa mumvura ine dilute lye, mushure mekumira kuti ijekeswe, iyo yekumusoro yakanyungudutswa yelye solution inomisikidzwa kuti iwane yakasimba sodium sulfide. Tablet (kana granule) sodium sulfide chigadzirwa chinowanikwa kuburikidza nekutamisa tank, tableting (kana granulation)
Chemical reaction equation: Na2SO4+2C→Na2S+2CO2
2.Absorption nzira: 380-420 g / L sodium hydroxide solution inoshandiswa kutora gasi remarara rine H2S> 85% hydrogen sulfide, uye chigadzirwa chakawanikwa chinoputika uye chinogadziriswa kuti chiwane sodium sulfide yakapera chigadzirwa.
Chemical reaction equation: H2S+2NaOH→Na2S+2H2O
3. Barium sulfide nzira, sodium sulfide inogona kuwanikwa se-yakagadzirwa apo sodium sulfate uye barium sulfide inoshandiswa pakuita metathesis kugadzirira precipitated barium sulfate. Izvozvo
Chemical reaction equation: BaS+Na2SO4→Na2S+BaSO4↓
4. Gasi kuderedza nzira, pamberi pesimbi inokonzeresa, hydrogen (kana kabhoni monoxide, mugadziri gasi, methane gasi) inobatwa ne sodium sulfate muvira rinovira, uye yepamusoro anhydrous granular sodium sulfide (ine Na2S 95%) inogona. kuwanikwa. ~97%).
Chemical reaction equation:
Na2SO4+4CO→Na2S+4CO2
Na2SO4+4H2→Na2S+4H2O
5.Kugadzira nzira, nzira yekunatsa inoshandisa sodium sulfide solution ine mutsara weinenge 4% ne-chigadzirwa mukugadzirisa kwekugadzira precipitated barium sulfate seyakasvibiswa. Mushure mekuipomba muhuviri-effect evaporator kuti ibude kusvika pa23%, inopinda mutangi inomutsa kubvisa simbi. , Mushure mekubviswa kwekabhoni kurapwa, iyo lye inopomba muevaporator (yakagadzirwa nechakachena nickel zvinhu) kuti iputse iyo lye kuti isvike pakusangana, uye inotumirwa kune dhiramu remvura inotonhorera mhando piritsi muchina.
Fekitori yedu inoshandisa nzira mbiri, nzira yekudzikisa marasha uye barium sulfide nzira, kugadzira sodium sulfide red flakes uye yellow flakes.
