Abstract
Dehydration of methanol resulted in an equilibrium mixture of methanol, DME and water
converted to olefins in a catalytic bed (MTP). In this research an industrial scale fixed bed reactor
of methanol dehydration was simulated based on computational fluid dynamics concepts.
Momentum transfer, heat transfer, mass transfer and chemical reaction rates was considered in
modeling and k-ε model was used to describe turbulence effects in the reactor. Catalytic bed was
considered as porous zone with laminar flow. Fluent commercial code was used to solve
conservation equations and contours of velocity, temperature and concentration of species was
derived as results of simulation. Comparison of simulation results by industrial reports showed
that the models could predict the behavior of reactor well.
Key Words: DME, Methanol, Dehydration, Computational Fluid Dynamics.
