Sodium Hydrosulfide tihthianghlim dan: A chanchin leh a hriatna

Petroleum leh chemical industry-ah chuan refinery process, vacuum distillation leh catalytic cracking te hian acidic gas a siam chhuak tlangpui. Heng acidic gas te hi a tlangpuiin 85%–95% hydrogen sulfide (H2S), 3%–10% carbon dioxide (CO2), 2%–5% organic gas, leh 0.5%–3% component dang atanga siam a ni.

Refinery tenau leh lian te chuan heng acidic gas te hi 30% sodium hydroxide (NaOH) solution hmanga hip lutin an tifai tlangpui thin. NaOH chu H2S nen an inrem a, a lo piang ta a ni sodium hydrosulfide hmanga siam a ni (NaHS) a ni. Solution chhunga NaHS concentration 30% a thlen chuan solution chu concentration process a paltlang thin. Dehydration leh concentration hnuah NaHS content chu 70% ah a pung a, chutah chuan molten NaHS chu flakes ah an slice leh thin.

Mahse, acidic gas-ah hian CO2 a awm avangin, enkawlnaah hian sodium carbonate (Na2CO3) ang chi bawlhhlawh a lo chhuak a, chu chuan NaHS product thianghlimna a ti tlem a ni.

Tin, open-drum flakers hmanga NaHS molten slice a nih chuan NaHS hian boruakah oxygen nen a inrem duh a, sodium thiosulfate (Na2S2O3) a siam a, chu chu a chhe awlsam a, dahkhawm a harsa hle bawk. Open slicing hian gas irritating gas a chhuah bawk a, production environment a ti bawlhhlawh bawk.
