Cumene isopropyl benzene is an important petrochemical as it is a raw material for This is the cost of propylene feed gas with propane impurity. The selectivity for cumene as a function of propylene conversion is given by the production of phenol. Cumene is manufactured by reaction of benzene and propylene. Unfor tunately, cumene can get alkylated further to produce undesired pdiisopropyl benzene which has only fuel value. In order to selectively get cumene, excess benzene is used in the reactor. The following gas phase exothermic reactions are of interest temperature around C pressure bar Benzene propylene Cumene Cumene propylene p diisopropylbenzene You are tasked to explore economic feasibility of this process. Consider that the desired production rate for cumene is kmolh Benzene feed is pure, however, propylene feed has propane as impurity. Consider that the reactor propylene conversion is Mol fraction of propylene in purge can be taken as Ratio of benzene to propylene at the reactor inlet is For this process, a Develop level and level flowsheets for the process. You are required to discuss pros and cons of the relevant decisions leading to these flowsheets with respect to this process. b Perform appropriate material balance and compute level economic potential. You can use the following data for calculations.
