Consider a quaternary mixture of components , , , and with relative volatilities , , and . This mixture is subject to an equilibrium-limited chemical reaction with reaction rate , where the equilibrium constant . This mixture is fed to a reactive distillation column such that the total number of plates is 17. The feed stage location is stage number 10, the reactive stages are from stage 6 to stage 14, and the feed composition is equimolar in and (i.e., the feed is composed of 50 mole % and 50 mole % ). The feed, a saturated liquid, has a flow rate of 100 kmol/hr. For simplicity, constant molal overflow (CMO) is assumed and heat effects are neglected.
