1) A scheme for the removal of H2S from a gas stream by scrubbing with water at 293K and 1.013105Pa is being considered. The liquid will initially contain 3.7mol%H2S. It is desired that the exiting gas stream contains only 0.2mol%H2S. The absorbing water will enter at the top of the tower that is H2S free. At the given temperature and pressure of the system, the equilibrium of H2S-water will obey Henry's law according to the following relationship: YH2S= 48.3XH25 a. For a countercurrent absorber, determine the moles of water that are required per mole of H2S-free carrier gas if 1.5 times the minimum ratio will be used. b. Determine the composition of the exiting liquid
