SIMULATION AND COMPARISON OF EQUILIBRIUM AND NONEQUILlBRlUM STAGE MODELS OF REACTIVE DISTILLATION

Abstract

In the prf!senr study. om dlltmctly different approaches are f0tlowed for mode/illg of reacl/I'e dlstillatlQn column. the equilibrium stage model and the nonequillbrlum siage model. These models are simulated with a computer code developed //I rhe present study usmg kM TUB programming 1n fhe equilibrium stage models. (ht' vapor and liquid
