given that the recovery of ethanol fromCO, stream is carried out by absorption in water. Assume the absorber operates at deg C and KRa. The total entering gas flow rate is kmolhr with mol contribution to recovery by ethanol. The absorbent is pure water. The specified recovery of ethanol is Kvalue for ethanol is Assuming an entering absorbent flow rate of times the minimum minimum absorbent now rate is kmolhr Determine the following using the Kremser method iThe number of equilibrium stages required
il The fraction of the entering water stripped into the gas Psat at deg C is KPa
ili. The fraction of the entering COz absorbed by the water when the partial pressure or H constant for CO is atm. Note: ethanol entering is kmolhr Dalton's Law is applicable to the gas system of the plant
