Abstract

A ternary semicontinuous system for the separation of bio-dimethyl ether from methanol and water is presented. The performance of eight potential control configurations, including the application of temperature inferential control, is evaluated. Dynamic simulations of the semicontinuous system and associated control scheme demonstrate that the temperature inferential control configuration is effective in achieving the separation objectives while remaining within operational limits. The semicontinuous system using the inferential temperature control scheme is simulated and shown to be economically preferable to the traditional continuous process for a range of production rates. © 2013 Canadian Society for Chemical Engineering
