Abstract
La presente se refiere a la recuperación de alcoholes, en particular etanol, a partir de un producto de etanol crudo obtenido de la hidrogenación de ácido acético con el uso de un proceso de energía reducida. El producto de etanol crudo se puede alimentar a una columna de destilación en la que se retira una porción sustancial del agua con el ácido acético en el residuo. Se puede retirar agua adicional mediante una unidad de adsorción por cambio de la presión, un tamiz molecular y/o una membrana. La extracción de etanol también se puede utilizar para reducir la concentración de etanol en las corrientes de reciclado.Reivindicación 1: Un proceso para producir etanol, que comprende los siguientes pasos: hidrogenar ácido acético de una corriente de alimentación de ácido acético en un reactor para formar un producto de etanol crudo; separar al menos una porción del producto de etanol crudo en una columna en un primer destilado que comprende etanol, acetato de etilo, y al menos 5% en peso de agua, y un primer residuo que comprende ácido acético y agua; en donde una porción sustancial del agua que se halla en el producto de etanol crudo que se alimenta a la columna se retira en el primer residuo; separar al menos una porción del primer destilado en una primera corriente que comprende etanol y agua, y una segunda corriente que comprende acetato de etilo; y retirar agua de la primera corriente con el uso de una unidad de retiro de agua para formar una corriente de producto de etanol, con la condición de que no se reitre ninguna cantidad de agua del primer destilado antes de separar la al menos una porción del primer destilado.
