Molecular weight of ethanol = 46 kg/kmol. Molecular weight of acetaldehyde = 44 kg/kmol. Molecular weight of hydrogen = 2 kg/kmol. Therefore‚ amount of acetaldehyde to be produced = 142.04 kmol/hr. Let conversion be 94%. Taking into account the losses let‚ the acetaldehyde produced to be some extra. Let acetaldehyde to be produced = 6500 kg/hr. Amount of ethanol required for 100% conversion = 6795.45 kg/hr. Therefore‚ ethanol required for 94% conversion = 7229.2 kg/hr. Vaporizer: 1000 C‚
