Anirreversible Isomerizationreaction A?R is carried out in a liquid phase in MFR. Thereaction is first order and the rate constant at 165oC is 0.7 hr-1. The activation energy of thereaction is 120 kJ/mol and the heat of reaction is -350 kJ/kg. The heat capacity of thereactants and products are 1.95 kJ/kg-K, the volumetric flow rate is 0.33 m3/hr, and the feedtemperature is 20oC. If the conversion is 95%, calculate (a) the reactor size and (b) the temperature of the reaction mixture, ifthe reactor is operated adiabatically
What is a Recycle reactor?In some reaction system, it is advantageous to divide the product stream and a partreturned to reactor as recycle to increase the conversion rate. These reactors are calledrecycle reactors.
(a) The safest conditions are achieved by the lowest temperature and pressure in the flash vessel. (b) Vapor flow to downstream equipment can cause a hazardous situation.
Find the minimum utility requirements for this process, for a minimum approach temperature of 10 °C.
