Abstract

Etileno es un químico de mercancía utilizado como un reactivo en la produccion de acetato de vinilo. Etileno es relativamente costoso, alentando así surecuperacion y reutilizacion en el proceso. La presente proporciona un método para la recuperacionde etileno de la corriente de depuracion de gas inerte de laanilla de reactor de un proceso de fase de vapor para hacer acetato de vinilo. El método de la presente incluye los pasos de poner en contacto la corriente dedepuracion de gas inerte que contiene etileno, con ácido acético en un recipiente de absorcion; descargar una corriente que contiene ácido acético y etilenodesde un aspecto del recipiente de absorcion; separar el etileno del ácido acético en la corriente, poniendo en contacto la corriente con gas etileno en unacolumna depuradora; y recuperar etileno desde una porcion superior de la columna depuradora. El método también puede incluir el paso de reciclar el etilenorecuperado a la anilla del reactor para uso adicional.
