Okushemeza Sodium Hydrosulfide: Ebirikukurataho n’okumanya

Omu by’amajuta n’eby’emibazi, emiringo y’okushemeza nk’okushohoza omu mwanya ogutarimu kintu kyona n’okushohoza ebiriisa ebirikureetaho asidi. Ezo nshaho ezirimu asidi okutwarira hamwe zirimu 85%–95% z’amaizi g’omuyaga (H2S), 3%–10% z’omuyaga gw’omuyaga (CO2), 2%–5% z’omuyaga gw’ebihangirwe, na 0.5%–3% z’ebindi bihingwa.

Amakorero makye n’agahango nigakira kushemeza emiyaga egi ey’asidi barikuginywanisa n’omubazi gwa sodium hydroxide (NaOH) ogurikwingana 30%. NaOH neekwatagana na H2S kuhanga . sodiyamu haidrosalfayidi (NaHS). Omubaro gwa NaHS omu nshonga ku gurikuhika ahari 30%, enkora neeza omu nkora y’okuta omu nkora. Bwanyima y‘okubura amaizi n‘okutaho omutima, NaHS eri omu mubiri neeyeyongyera kuhika ahari 70%, reero NaHS eshazirwe neesharaho omu bicweka.

Kwonka ahabw‘okugira ngu gaasi ezirimu asidi zirimu CO2, obukooko nka sodium carbonate (Na2CO3) nibubaho omu bwire bw‘okujanjaba, ekirikukyendeeza obushemeire bw‘ekintu kya NaHS.

Okwongyera ahari ekyo, ebipande by’engoma ebikingire byakoresibwa kusharaho NaHS eshazirwe, NaHS neekunda kukwatagana na oxygen eri omu mwanya, ekakora sodium thiosulfate (Na2S2O3), erikukira kusheenyagurika kandi egumire kubiika. Okusharaho okukingire nakyo nikireeta omuyaga ogurikuteganisa, gushiisha omwanya gw’okukoramu.

Nyiga aha kutunga esente z'okugura sodium hydrosulfide, nihaija kubaho eby'okutangaaza.
