Kusalazya Sodium Hydrosulfide: Makani aakusaanguna aluzibo

Mumakwebo aamafuta amakemikalu, nzila zyakusanzya mafuta zilimbuli kusanzya mafuta aamuwo akukwasula mafuta kanjikanji zipa kuti kube muya uulaa asidi. Aaya magesi aajisi asidi kanjikanji ajisi 85%–95% hydrogen sulfide (H₂S), 3%–10% carbon dioxide (CO2), 2%–5% magesi aajisi buumi, antoomwe a 0.5%–3% zibeela zimwi.

Mafakitali masyoonto aakati-akati kanjikanji alabamba muya ooyu uujisi asidi kwiinda mukuunywa a 30% ya sodium hydroxide (NaOH) solution. NaOH ilaswaangana a H2S kuti ipange sodium hydrosulfide (NaHS). Eelyo mweelwe wa NaHS mumusamu nuusika ku 30%, musamu ulainda munzila yakuyungizya. Musule akumana maanzi akuvwula, NaHS ilatanta kusika ku 70%, mpawo NaHS iiteteete ilakosolwa kuba zibeela.

Nokuba boobo, mbwaanga muya uujisi asidi ulaa CO₂, zintu zisofweede zilimbuli sodium carbonate (Na₂CO₃) zilapangwa muchiindi chakusilikwa, ikucheesya kusalala kwa NaHS.

Kuyungizya waawo, eelyo ma flakers aajalukide nabelesyegwa kutyola NaHS, NaHS ilakonzya kuswaangana a oxygen mumuwo, akupanga sodium thiosulfate (Na2S2O3), eeyo iifwambaana kunyonyooka alimwi iikatazya kuyobola. Kugela kwaanze akwalo kulagwisya muya uunyemya, akusofwaazya busena bwakupanga.

Dina aawa kuti ujane muulo wa sodium hydrosulfide, kuyooba zintu zigambya.
