Abstract
Se describe un proceso para la fabricación de un producto químico en el cual se combina una pluralidad de corrientes de alimentación individuales quecontienen reactivo, para formar una corriente de alimentación mezclada para un reactor (40), y en donde al menos una de la pluralidad de corrientes dealimentación (20) está sujeta a variaciones en la concentración de reactivo, y la otra de la pluralidad de corrientes de alimentación (24) es esencialmenteestable en la concentración de reactivo,una relación deseada de concentraciones de reactivo relativas en la corriente de alimentación mezcladase mantiene por un sistema de control que infiere una relación de concentración de reactivo en la corriente de alimentación mezcladaen base a las medicionesdel proceso y los parámetros de alimentación relacionados con la pluralidad de corrientes que contienen material de alimentación, antes de que seancombinadas. En uso,la velocidad de flujo de la corriente de alimentación quees esencialmente estable en la concentración de reactivo se manipula para mantenerlas concentraciones de reactivos inferidas en la corriente mezclada.
