Sodium Hydrosulfide Kɔkɔe: Nyatakakawo Kple Gɔmesesewo

Le ami kple atikewɔƒewo la, zi geɖe la, amiɖaƒe ƒe mɔnuwo abe vacuum distillation kple catalytic cracking ene naa acidic gaswo dona. Zi geɖe la, acid-ya siawo nyea 85%–95% hydrogen sulfide (H2S), 3%–10% carbon dioxide (CO2), 2%–5% organic gas, kple 0.5%–3% ƒe akpa bubuwo.

Zi geɖe la, amiɖaƒe suewo kple gãwo wɔa atike na ya siawo siwo me acid le to wo xɔxɔ kple sodium hydroxide (NaOH) 30% ƒe tsi me. NaOH la wɔa dɔ kple H2S tsɔ wɔa nu sodium hydrosulfide si wotsɔna ƒoa ƒui (NaHS) ƒe agbalẽa. Ne NaHS ƒe agbɔsɔsɔ le tsia me ɖo 30% la, ʋeʋẽa toa ʋeʋẽ ƒe ɖoɖo aɖe me. Le tsikuɖiɖi kple eƒe ʋeʋẽ megbe la, NaHS ƒe agbɔsɔsɔ dzina ɖe edzi va ɖoa 70%, eye emegbe wolãa NaHS si wofa la wòzua ƒuƒu.

Gake esi wònye be CO2 le ya siwo me aɖi le me ta la, ɖiƒoƒowo abe sodium carbonate (Na2CO3) ene dona le atikewɔwɔ me, si wɔnɛ be NaHS-nuwɔna ƒe dzadzɛnyenye dzi ɖena kpɔtɔna.

Tsɔ kpe ɖe eŋu la, ne wozã gaƒoɖokui siwo le ʋuʋu ɖi tsɔ lã NaHS si wofa la, NaHS la dina be yeawɔ nu kple ɔksidzin si le yame, si wɔnɛ be sodium thiosulfate (Na2S2O3), si gblẽna bɔbɔe eye edzraɖo sesẽna. Ne wotso lãɖeɖe le gaglãgbe hã ɖea ya siwo doa dziku na ame, si ƒoa ɖi nuto si me wowɔa nuawo le.

Zi afisia dzi be nàkpɔ sodium hydrosulfide ƒe asi dzi ɖeɖe kpɔtɔ, nu wɔnukuwo anɔ anyi.
