Litaba

1. Mokhoa oa ho fokotsa mokokotlo oa mashala, mashala a mahareng le a mahareng le a boima ba 'mele) (21-22.5 ° C,' me ha a fokola qhala mokelikeli ka setopo se hlobolotsang, ka mor'a ho hlakisoa, tharollo ea holimo e kholo e tsepamisitse maikutlo ho fumana sekhahla se tiileng sa sodium sulfide. Letlapa (kapa granule) sehlahisoa sa sodium sulfide se fumanoa ka tanka ea phetisetso, litafole (kapa granulation)
Atuation ea lik'hemik'hale ea lik'hemik'hale: na2so4 + 2c → Na2s + 2Co2

Mokhoa oa ho khutlisa: 380-420 G / L Sodium hydroxide e sebelisoang ho monya khase e nang le H2s>
Tlhahlobo ea chelete ea lik'hemik'hale: H2s + 2Áooh → Navs + 2Ho

3. Mokhoa oa Sulfide oa Barium Sulfide o ka fumanoa e le sehlahisoa sa sodium sulfate le li-sulfate li sebelisetsoa ho lokisa metatathesis ho lokisa sulfate e sa tsitsang. Seo
Equation Intection: Bas + Navso4 → Na2s + Baso4 ↓

4. Mokhoa oa ho fokotsesela ha khase fumanoa. ~ 97%).
TLHOKOMELISO EA NKAHLA
Na2so4 + 4co → Navs + 4Co2
Na2so4 + 4H2 → Na2s + 4H2O

Mokhoa oa ho hana) mokhoa oa sulfide o sebelisa tharollo ea sodium sulfide le khatello ea lihlahisoa tse ka bang 4% ka ts'ebetso ea ho hlahisa thepa e halikiloeng e le thepa e tala. Kamora hore e ehelle ka bongata bo boholo bo boholo ho fetolela ho isa ho 23%, e kena tankeng e susumetsang ho tlosa tšepe. Ka mor'a kalafo ea ho tlosa Carbon, ly e hapuoe ka mouoane (e entsoe ka thepa e hloekileng ea nickel) ho iphelisa, 'me ea romeloa mochini oa tahi.

Fele ea rona e sebelisa mekhoa e 'meli ea mokokotlo le mokhoa oa ho fokotsa mokokotlo oa mokokotlo, ho hlahisa likhechana tse khubelu tsa sodium sulfide tse khubelu le li-flakes tse khubelu.
