Explain the graphical design procedure for finding the reactor size for adiabatic operations ofPlug flow and Mixed flow reactors.(May-2005 & Dec-2005) and The flowthrougha tubularreactor, inwhicha first order irreversible liquid phase reaction takes place, is increased by 20% and in order to maintain the same fractional conversion it isdecided to change the reactor operating conditions. The reaction has an activation energy of4kcal/mol and the initial temperature is 150oC. Find the new operating temperature of thereactor.(Dec-2004 & Dec-2005) and Discuss the stability criteria for exothermic reactions in Mixed flow reactors
