ResumenSe presentan resultados de la simulación de la operación de desodorización de aceites vegetales. Para efectos de simulación, el aceite de soja se modeló como una mezcla multicomponente de cinco compuestos: triglicérido, ácido graso, esterol, tocoferol y escualeno. Se estudiaron las condiciones de operación de flujo cruzado y flujo en contracorriente. Se varió la temperatura, presión y tiempo de contacto, se estudió cantidad de tocoferoles, esteroles y escualeno en el destilado y la presencia de compuestos trans en el aceite. Los resultados obtenidos estuvieron de acuerdo con resultados experimentales, e indicaron que el flujo en contracorriente es más conveniente desde el punto de vista de la calidad del destilado y del aceite, así como del consumo de vapor.

For simulation purposes, the soybean oil was modelled as a five component mixture: triglyceride, fatty acid, sterol, tocopherol and squalene. Two types of flow, cross and countercurrent, were studied. The process temperature, pressure and contact time were changed, the amount of tocopherol, sterol and squalene in the distillate and the presence of trans compounds in the vegetable oil were analyzed. The results were in agreement with experiment and indicate that countercurrent flow is more convenient from the point of view of quality of the distillate and of the oil, as well as of steam consumption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
