Ku basisa Sodium Hydrosulfide: Ndzavisiso na Vutivi

Eka bindzu ra petroliyamu na tikhemikhali, maendlelo ya refinery yofana na vacuum distillation na catalytic cracking hi ntolovelo ya humesa tigasi ta acid. Tigasi leti ta acid hi xitalo tina 85%–95% wa hydrogen sulfide (H2S), 3%–10% carbon dioxide (CO2), 2%–5% wa tigasi ta organic, na 0.5%–3% wa swiphemu swin’wana.

Ti refineries letintsongo na tale xikarhi titala ku tshungula ti gasi leti ta acid hiku ti tswonga hi 30% sodium hydroxide (NaOH) solution. NaOH yi endla reaction na H2S kuva yi vumba sodiyamu ya hayidirosulfayidi (NaHS) (NaHS). Loko nhlayo ya NaHS eka solution yifika eka 30%, solution yi hundza eka maendlelo ya concentration. Endzhaku ka dehydration xikan’we naku hlanganisiwa, nhlayo ya NaHS yi tlakuka kuya eka 70%, naswona NaHS leyi n’okiweke yitlhela yi tsemiwa kuva yiva ti flakes.

Hambiswiritano, tani hileswi ti gasi ta acid tingana CO2, thyaka rofana na sodium carbonate (Na2CO3) ri endliwa hinkarhi wa vutshunguri, leswi hungutaka ku basa ka xitirhisiwa xa NaHS.

Ku engetela kwalano, loko ti open-drum flakers titirhisiwa ku tsemelela NaHS leyi n’okiweke, NaHS yitala ku endla reaction na oxygen emoyeni, yi endla sodium thiosulfate (Na2S2O3), leyi talaka ku onhaka naswona switika ku yi hlayisa. Open slicing yitlhela yi humesa tigasi leti hlundzukisaka, leswi thyakisa ndzhawu ya vuhumelerisi.
