Sodium Hydrosulfide ni Akɛtsuɔ Nii: Shishijee kɛ Nilee

Yɛ mu kɛ tsofafeemɔ nitsumɔhei lɛ, nibii ni akɛtsuɔ nii kɛjieɔ muji tamɔ vacuum distillation kɛ catalytic cracking lɛ haa kɔɔyɔɔ ni mli edɔ baa. Nɛkɛ kɔɔyɔɔ ni mli edɔ nɛɛ mli 85%–95% ji haidrojin sulfaid (H2S), 3%–10% kɔɔyɔɔ ni mli edɔ (CO2), 2%–5% kɔɔyɔɔ ni wala yɔɔ mli, kɛ 0.5%–3% nibii krokomɛi.

Bei pii lɛ, tsɔnei bibii kɛ mɛi ni tsuɔ nii yɛ mli lɛ tsuɔ nɛkɛ kɔɔyɔɔ ni mli edɔ nɛɛ ahe nii kɛtsɔ sodium hydroxide (NaOH) ni ji 30% ni akɛwoɔ mli lɛ nɔ. NaOH lɛ kɛ H2S lɛ feɔ ekome ni efeɔ sodium hydrosulfaid (NaHS). Kɛji NaHS ni yɔɔ tsɔne lɛ mli lɛ shɛ 30% lɛ, tsɔne lɛ tsɔɔ tsɔne ni haa mɔ he jɔɔ lɛ mli. Beni nu lɛ efo mli ni ekɛ ehe wo mli lɛ, NaHS ni yɔɔ mli lɛ yaa hiɛ kɛyashɛɔ 70%, ni no sɛɛ lɛ, afolɔ NaHS ni mli edɔ lɛ mli afee ŋmɔtɔ.

Shi, akɛni CO2 yɛ kɔɔyɔɔ ni mli edɔ lɛ mli hewɔ lɛ, muji tamɔ sodium carbonate (Na2CO3) jeɔ kpo yɛ helatsamɔ be mli, ni no haa NaHS nibii lɛ ahe tsemɔ baa shi.

Kɛfata he lɛ, kɛ́ akɛ open-drum flakers tsu nii ni akɛfolɔ NaHS ni mli edɔ lɛ, NaHS lɛ kɛ kɔɔyɔɔ ni haa wala yibii lɛ tsuɔ nii lɛ feɔ ekome, ni ehaa sodium thiosulfate (Na2S2O3) baa, ni efiteɔ oya ni ewa akɛ abaato. Slicing ni agbeleɔ naa lɛ hu jieɔ kɔɔyɔɔ ni woɔ mɔ mli la, ni efiteɔ he ni afeɔ nii yɛ lɛ.

Klikimɔ biɛ koni onine ashɛ sodium hydrosulfide he nyɔmɔwoo nɔ, naakpɛɛ nii baaba.
