WebThis study aims to predict the increase in the dimethyl ether yield due to recycle integration to a reaction-distillation system for the production of dimethyl ether through methanol dehydration. A one-dimensional phenomenological model of an isothermal methanol dehydration reactor and a shortcut model of distillation columns were used to achieve … WebA catalytic distillation process for methanol dehydration to dimethyl ether (DME) has been modeled using the experimentally determined kinetic data. The results were incorporated into the rate-controlled reaction mode for RadFrac, a part of the commercial simulation program Aspen Plus. It was shown that synthesis of high purity DME can be ...
