b. Ethylene (C2H4) may be formed from ethane (C2H6) by dehydrogenation process according to the reaction: C2H6 (9) C2H4 (9) + H2 (9) In a commercial reactor system, the ethane is supplied as a liquid at 25C to a heater where it is heated and vapourised leaving as a vapour at 400C. The vapour then passes the catalytic reactor in which a conversion of 50% is achieved. It may be assumed that there are no other reactions, that operation is at a pressure of one atmosphere and that the stream leaving the reactor is all in the vapour state. With a complete block diagram of the process, determine the heat transfer rate (kW) required to the reactor if it is operated isothermally. Evaluate on the value of the heat transfer rate obtained from your calculation.
