Acetaldehyde is synthesized by the catalytic dehydrogenation of ethanol: C2H5OH + CH3CHO + H2 Fresh feed (pure ethanol) is blended with a recycle stream (95 mole% ethanol and 5% acetaldehyde), and the combined stream is heated and vaporized, entering the reactor at 280C. Gases leaving the reactor are cooled to condense the acetaldehyde and unreacted ethanol. Off-gas from the condenser is sent to a scrubber, where the uncondensed organic compounds are removed and hydrogen is recovered as a by-product. The condensate from the condenser, which is 45 mole% ethanol, is sent to a distillation column that produces a distillate containing 99 mole% acetaldehyde and a bottoms product that constitutes the recycle blended with fresh feed to the process. The production rate of the distillate is 1000 kg/h. The pressure throughout the process may be taken as 1 atm absolute. If the fresh feed to the system flows at 23.4 kmol/h, the condensate flow rate is 42.6 kmol/h, and the single-pass conversion of ethanol in the reactor is 54.6%, calculate the flow rates of ethanol and hydrogen leaving in the reactor effluent (kmol/h).
