Ịdị ọcha nke Sodium Hydrosulfide: Ndabere na Nghọta

N'ụlọ ọrụ mmanụ ala na kemịkalụ, usoro mmepụta ihe dịka mwepụ ihe mkpofu na mgbawa catalytic na-emepụtakarị gas acidic. Gas acidic ndị a na-enwekarị 85%–95% hydrogen sulfide (H₂S), 3%–10% carbon dioxide (CO₂), 2%–5% gas organic, na 0.5%–3% ihe ndị ọzọ.

Ụlọ ọrụ mmepụta ihe nta na nke ọkara na-agwọkarị gas acidic ndị a site n'iji mmiri sodium hydroxide (NaOH) 30% na-amịkọrọ ha. NaOH na-emeghachi omume na H₂S iji mepụta sodium hydrosulfide (NaHS). Mgbe ntinye NaHS dị na mmiri ahụ ruru 30%, mmiri ahụ na-abanye usoro ntinye. Mgbe mmiri kpọnwụrụ akpọnwụ na ntinye, ọdịnaya NaHS na-abawanye ruo Pasentị iri asaa, a na-egbutuzikwa NaHS ahụ gbazere agbaze n'ime iberibe.

Agbanyeghị, ebe ọ bụ na gas acidic nwere CO₂, ihe ndị na-adịghị ọcha dịka sodium carbonate (Na₂CO₃) na-apụta n'oge ọgwụgwọ, nke na-ebelata ịdị ọcha nke ngwaahịa NaHS.

Ọzọkwa, mgbe e ji ihe ndị na-eme ka ihe na-egbu egbu nke e ji drum kpụọ mee ka NaHS gbazee, NaHS na-emeghachi omume na ikuku oxygen, na-emepụta sodium thiosulfate (Na₂S₂O₃), nke na-emebi emebi ma sie ike ịchekwa. Mbepụ mepere emepe na-ewepụtakwa gas na-akpasu iwe, na-emebi gburugburu ebe mmepụta.

Pịa ebe a iji nweta ọnụahịa mbelata ọnụahịa maka sodium hydrosulfide, ihe ijuanya ga-adị.
