Fresh feed (Stream 1) is blended with a recycle stream, and the combined stream is fed to a reactor. Gases leaving the reactor are cooled to -15 C condensing the acetaldehyde (" = 168 mmHg) and unreacted ethanol (% = 3.71 mmHg). The condensate, which contains 45 mole% ethanol, is in equilibrium with the off-gas to the scrubber (Stream 2) and 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 (Stream 3) is 50 kmol/hr. The pressure throughout the process is 760 mmHg absolute. (a) Find the composition of hydrogen in Stream 2, y2H2 . (b) Find the flowrate of fresh feed to the process, ( (kmol/hr).
