Abstract
La presente invención se refiere a un procedimiento para separar tetrahidrofurano a partir de una mezcla de alimentación que contiene agua, alcanol inferior y tetrahidrofurano que comprende destilar la mezcla en una primera zona de destilación a una primera presión, recuperando de una parte superior de la zona de destilación una primera mezcla vaporosa que comprende agua, alcanol inferior y tetrahidrofurano, sometiendo el material de la primera mezcla vaporosa a condiciones de condensación en una zona de condensación pasando la condensación de la zona de condensación a una segunda zona de destilación operada a una segunda presión superior a la primera presión, recuperando de una parte superior de la segunda zona de destilación una segunda mezcla vaporosa que comprende agua, alcanol y tetrahidrofurano, que tiene una concentración inferior de tetrahidrofurano que la primera mezcla vaporosa y recuperando de una parte inferior de la segunda zona de destilación una corriente que substancialmente comprende tetrahidrofurano puro, caracterizado porque la segunda mezcla vaporosa se combina con la primera mezcla vaporosa antes de la admisión a la zona de condensación.
