The procedure used for the material balance calculation is the Initial Zero Recycle Method. The process used to describe the method is the industrial synthesis of cumene (isopropylbenzene) from benzene and propylene at 623 K (350°C) and 30 ATM. The results show that the iterative solution of the material balance of the process converged in four iteration cycles.
