Pamaglinis keng Sodium Hydrosulfide: Background ampo Insights

keng industria ning petrolyu ampo chemical, deng prosesu ning refinery antimo ing vacuum distillation ampo ing catalytic cracking keraklan maggenerate lang acidic gases. Deng acidic a gas keraklan atin lang 85%–95% hydrogen sulfide (H₂S), 3%–10% carbon dioxide (CO2), 2%–5% organic gases, ampo 0.5%–3% aliwang sangkap.

Deng malati ampo katamtaman a refinery keraklan gagawan da la deng acidic a gas kapamilatan ning pamagsipsip kareti keng 30% sodium hydroxide (NaOH) a solusyun. Ing NaOH maki reaksyun ya keng H2S para maging sodium hydrosulfide (NaHS). Nung ing NaHS concentration keng solusyun miras yang 30%, ing solusyun dumalan ya keng prosesu ning concentration. Kaybat ning pamag-dehydrate ampo pamag-concentrate, ing NaHS content daragul ya angga 70%, at ing molten NaHS mibabad ya keng flakes.

Makanyan man, uling deng acidic gases atin lang CO2, deng impurities antimo ing sodium carbonate (Na2CO3) mipalyari la kabang magtreat la, at babawasan na ing kalinisan ning NaHS product.

Dagdag pa, nung gamitan la reng open-drum flakers para pututan ing molten NaHS, ing NaHS maki ugali yang magreact keng oxygen keng angin, gagawang sodium thiosulfate (Na2S2O3), na prone keng pangasira ampo masakit yang i-store. Ing open slicing magpalwal yang makasumami a gas, makadumi keng kapaligiran ning pamaglalang.

Pindutan me ini para mika diskwentu kang sodium hydrosulfide, atin kang surpresa.
