Abstract

Un aparato y un método mejorados para producir ácido acético que incluye condensar el vapor de la parte superior par proveer reflujo a la columna de extremos livianos así como condensar el vapor proveniente de la porcion central de la columna deextremos livianos para aumentar la capacidad. El resultado o la carga de la columna de extremos livianos están sustancialmente reducidos sin comprometer la calidad del producto. Reivindicacion 1: Un proceso de carbonilacion para producir ácidoacético que comprende: (a) carbonilar metanol o sus derivados reactivos en presencia de agua, un catalizador seleccionado de catalizadores de rodio, catalizadores de iridio y sus mezclas, y un promotor de yoduro de metilo para formar una mezcla dereaccion de ácido acético en un reactor; (b) separar la corriente de la mezcla de reaccion de ácido acético en una corriente de reciclado de líquido y una corriente de producto crudo que incluye ácido acético, yoduro de metilo, acetato de metilo yagua; (c) alimentar la corriente de producto crudo a una columna de extremos livianos que tiene una zona de destilacion que incluye una porcion superior, una porcion inferior y una porcion central provista con una tubería lateral de extraccion deproducto; (d) purificar la corriente de producto crudo en la zona de destilacion de la columna de extremos livianos para extraer yoduro de metilo y acetato de metilo y generar una corriente de producto purificado, en donde la corriente de productopurificado tiene menor concentracion de yoduro de metilo y acetato de metilo que la corriente de producto crudo, y en donde la etapa de purificar la corriente de producto crudo incluye (i) condensar el vapor de la parte superior de la zona dedestilacion de la columna de extremos livianos, (ii) devolver al menos una porcion del vapor condensado de la parte superior como líquido de reflujo a la zona de destilacion de la columna de extremos livianos, y (iii) condensar el vapor de laporcion central de la zona de destilacion de la columna de extremos livianos; y (e) extraer una corriente de producto purificado de la tubería lateral de la columna de extremos livianos.
