Lonyo Sodium Hydrosulfide: Lok ma okato ki jami ma kinongo

I lok ma mako moo ki jami ma ki yubu ki jami ma ki lwongo ni chemical, yub me yubu moo ma calo vacuum distillation ki catalytic cracking pol kare gi kelo yamo ma ki lwongo ni acidic gases. Yamo ma ki lwongo ni acidic ni pol kare tye ki 85%-95% hydrogen sulfide (H2S), 3%-10% carbon dioxide (CO2), 2%-5% organic gases, ki 0.5%-3% jami mukene.

Ka yubu moo ma tiino ki ma idyere pol kare gi tiyo ki yamo ma ki lwongo ni acidic ni kun gi kwanyo gi ki 30% sodium hydroxide (NaOH) solution. NaOH ni rwate ki H2S me yubu sodium hydrosulfide (NaHS). Ka NaHS ma tye i gin ma ki keto ni oo 30%, gin ma ki keto ni okato ki i yub me keto ne. Iyonge kwanyo pii ki keto ne, wel NaHS mede nio wa i 70%, ki NaHS ma oling ni ki poko ne i dul mogo.

Ento, kit ma yamo ma ki lwongo ni acidic ni tye ki CO2, jami ma calo sodium carbonate (Na2CO3) ki yubu i kare me tic kwede, ma dwoko piny leng pa gin ma ki yubu ki NaHS.

Medo ikom meno, ka ki tiyo ki jami ma ki lwongo ni open-drum flakers me poko NaHS ma oling, NaHS ni twero tic ki yamo ma tye i yamo, ma yubu sodium thiosulfate (Na2S2O3), ma twero balo ne tek me gwoko ne. Nyutu jami ma oyabe bene kwanyo yamo ma kelo arem cwiny, ma balo kabedo ma ki yubu iye jami.

Dii kany me nongo wel ma ki dwoko piny pi sodium hydrosulfide, obi bedo ki jami me awura.
