Question
The syuthesis of acetaldehyde CHO involves the catalytic delyydration of ethanol, which es follows:
CHO
The process involves the blending of fresh feed, which is pure ethmol with a rec de stream consisting of mol ethanol and acetaldelyde. The combined mikture is then beated and yaporized before entering the reactor at a tempeature of The grecous products leaving the reactor are cooled to Tlo conderse the acetaldelyde and unrected ethanol. The resulting gas is then directed to a scrubber to eliminte any remiining organic compounds, witile also recovering hydrogea as a byproduct. The condensed liquid from the condesser, conhining mol ethanol, is further processed in a distillation columo. This column produces a distilate that coatains mol acetaldelyde, while the bottons product constitules be recycled strem that is blended with fresh feed for the subsequeat steps of the process.
a Illustrate and label a Block Flow Diggram BFD stream for the catalytic reaction of acetaldehyde.

b Bused on the above BFD and using coned ISA symbology, prepure a Process Flow Diagram PFD for this complete process.
