Purifying Sodium Hydrosulfide: Bakgrɔn ɛn Insayt

Insay di petrolium ɛn kemikal industri, rifinɛri prɔses dɛn lɛk vaykum distileshɔn ɛn katalaytik krak tipikli de mek asid gas dɛn. dis asid gas dεm jεnarali kכnsis fכ 85%–95% haydrojεn sכlfayd (H2S), 3%–10% kabכn dayכksayd (CO2), 2%–5% כrganik gas dεm, εn 0.5%–3% כda kכmכpכnεnt dεm.

Smɔl ɛn midul saiz rifinɛri dɛn kin trit dɛn asid gas ya bay we dɛn de absɔb dɛn wit 30% sɔdiɔm haydroksayd (NaOH) sɔlvushɔn. Di NaOH de riak wit H2S fɔ mek sodium haydrosulfayd (NaHS) we dɛn kɔl). we di NaHS kכnsantreshכn insay di sכlushכn rich 30%, di sכlushכn de כnda wan kכnsantreshכn prכsεs. afta dεn dεhaydrayshכn εn kכnsantreshכn, di NaHS kכntεnt de inkrεs to 70%, εn dεn de slais di NaHS we mכlt insay fכl dεm.
