Abstract

En un proceso para la fabricación de un producto químico, una corriente de alimentación de hidrocarburo reactiva, la cual varía en composición delcomponente reactivo, se combina con una corriente de alimentación de hidrocarburo no reactivo pero compatible, para formar una corriente dehidrocarburo mezclada la cual se combina entonces con una corriente de alcohol reactivo de concentración estable de su componente reactivo, para formar unacorriente de alimentación completa para el reactor. Una relación deseada de las concentraciones del reactivo relativas en la corriente de alimentación completapara el reactor es mantenida por un sistema de control, el cual mantiene una concentración estable en la corriente de hidrocarburo, mezclada manipulando lavelocidad de flujo de la corriente de alimentación de hidrocarburo no reactiva en respuesta a una medición de concentración en la corriente de hidrocarburo,mezclada. El control de la relación de flujo se aplica entonces para mantener una relación deseada de los reactivos en la corriente de alimentación completapara el reactor, calculando una relación de flujo de la corriente de hidrocarburo mezclada para la corriente de alimentación de alcohol reactivo. Larelación de flujo calculada es la variable del proceso que entra a un controlador de relación establecida manualmente, el cual manipula la velocidadde flujo de la corriente de alimentación de alcohol reactivo en respuesta a la relación de flujo.
