Abstract
In this thesis, theoretical investigations have been made concerning reactive distillation
columns. The detailed steady state modeling, and simulation are made for biodiesel
produced by reactive distillation. This study was performed through several steps in order
to construct and develop an improved steady state model based on recent manner of MESH
equations (Mass balance, Equilibrium, Summation of composition, and Heat balance) the
reaction portion added to the mass and energy balance. This model was developed to study
the behavior of multi component non ideal mixture in reactive distillation. The set of
algebraic equations governing steady state composition profile in a reactive distillation
column are solved by using equation tearing or sequential method. The developed model
can be employed to simulate the reactive distillation operation. This model required the in
advance specification of number of reactive and non-reactive trays, the reflux ratio,
composition and flow rates of the feed, and heat duty to determine the result of the liquid
and vapor composition profiles, the temperature profile and the vapor and liquid flow rate
profile. The validity of the developed steady state equilibrium model had been evaluated by
comparing its predictions with another theoretical work. The calculations and simulations
in this thesis were obtained by using MATLAB environment, version 10.
