Agas flows at the rate of 15 kmol/s at 298 k and 1 atm with a h2s content of 0.10 mol%. 95% of the h2s is to be removed by absorption with a pure liquid at 298 k. the design liquid flow rate will be 30% higher than the minimum. under these conditions, the equilibrium line is y = 10x/(1-9x) based on solute free basis. i) calculate the operating flow rate of the liquid and the h2s concentration in the liquid leaving the absorber
