1998). By assuming the plug flow of H2S gas in the stationary bed, the Michaelis–Menten-type equation was applied as follows:
dC VmC Sa
¼ a ð7Þ
dl Ks þ C F
¼ V mC 1 a; ð8Þ
Ks þ C L SV
where C, H2S concentration (lL/L); l, length of column (m); Vm, maximum removal rate (g S/kg dry material h); Ks, saturation
