Simulation of production process for Ethyl Tert-Butyl Ether (ETBE). Influence of the ethanol/isobutene ratio [Simulación del Proceso de Producción del Éter Etil Tert-Butílico (ETBE). Influencia de la Relación Etanol/Isobuteno]

This work describes a methodology which combines conceptual design and process simulation to determine the influence of the molar feed ratio of ethanol/isobutene on tert-butyl ethyl ether selectivity. The conceptual design of distillation columns was based on the residue curve map and it allowed determination of feasible separation schemes and maximization of the concentration of ether in the stream bottom of the distillation column. Simulation of the process has allowed determining the operating variables and design parameters for the reactors and the distillation column. It is concluded that this methodology significantly reduces the time required to obtain results with a process simulator.
