Gutunganya Sodium Hydrosulfide: Amavu n'amavuko n'ibitekerezo

Mu nganda zikora peteroli n'ibinyabutabire, ibikorwa byo gutunganya ibikomoka kuri peteroli nko gusya ibintu mu buryo bwa vacuum no gukata ibintu mu buryo bwa catalytic bikunze gutanga imyuka ikomoka kuri aside. Iyi myuka ikomoka kuri aside muri rusange igizwe na 85%–95% ya hydrogen sulfide (H₂S), 3%–10% ya dioxyde de carbone (CO₂), 2%–5% ya gaze organic, n'ibindi bice 0.5%–3%.

Inganda nto n'iziciriritse zitunganya iyi myuka ihumanya zikoresheje umuti wa 30% wa sodium hydroxide (NaOH). NaOH ikorana na H₂S igakora sodium hydrosulfide (NaHS). Iyo ingano ya NaHS mu muti igeze kuri 30%, umuti unyura mu nzira yo gukurura. Nyuma yo kubura amazi no gukurura, ingano ya NaHS iriyongera kugeza kuri 70%hanyuma NaHS ishongeshejwe igakatwamo uduce duto.

Ariko, kubera ko imyuka ikomoka kuri aside irimo CO₂, imyanda nka sodium karubone (Na₂CO₃) iravuka mu gihe cyo kuyitunganya, bigabanura ubuziranenge bw'umusaruro wa NaHS.

Byongeye kandi, iyo uduce tw’ibumba dufunguye dukoreshejwe mu gukata NaHS ishongeshejwe, NaHS ikunda kugirana na ogisijeni mu kirere, bigatuma habaho sodium thiosulfate (Na₂S₂O₃), ishobora kwangirika kandi ikagoranye kubika. Gukata bifunguye binasohora imyuka ikarishye, bigahumanya ibidukikije.

Kanda hano kugira ngo ubone ibiciro byagabanijwe kuri sodium hydrosulfide, hazabaho gutungurwa.
