Consider a wetted-wall tower used for desulfurization. An aqueous liquid stream running down the tower is in direct contact with a stream of methane flowing up. At specific point in the tower, the concentration of hydrogen sulfide (HS) in the vapor space is 12 mol %. The concentration of HaS in the liquid phase at the same point 0.04 mol %. The total pressure in the tower is 5 bar, and the Henry's law coefficient for H2S in water (Pa=Ha) is 600 bar. Determine the rate of flux of H,S. The mass-transfer coefficient Kg = 6.27 x 10-4 kmol/s m2 Pa. Is the flux into or out of the liquid stream?
