Calculate the diffusion constant of argon at 20°C and at the following pressures. Take o = 0.36 nm2. If a pressure gradient of 1.0 bar-m-1 is established in a pipe, what is the flow of gas due to diffusion? (a) 2.24 Pa |m².s-1 mol-m-2.s-1 (b) 224 kPa D |m².s¬1 mol-m-2.s-1 (c) 22.4 MPa D |m²-s=1 mol-m-2.s-1

Acetaldehyde is synthesized by the catalytic dehydrogenation of ethanol: 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 280°C. 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.   Calculate the flow rate of the distillate in mol/s (use the actual composition of the distillate, 99 mole% acetaldehyde and 1 mole%…
