Zusammenfassung: | A process for monitoring and controlling reactor conditions during the production of acetic acid by catalyzed carbonylation of methanol is provided. The process of the present invention comprises measuring the density of the heavy phase of the light ends distillation column in the purification system of the carbonylation process. The density measurement is used to adjust the feed of methanol and/or regulate the temperature in the reaction zone to optimize reactor conditions. The density measurement may also be used to adjust other parameters in the reactor system. The invention is also directed to the system for manufacturing acetic acid based on the process control procedure described.
Se proporciona un procedimiento para monitorear y para controlar las condiciones de un reactor durante la produccion de acido acetico por carbonilacion catalizada de metanol; el procedimiento de la presente invencion comprende medir la densidad de la fase pesada de la columna de destilacion de fracciones ligeras en el sistema de purificacion del procedimiento de carbonilacion; la medicion de la densidad se utiliza para ajustar la alimentacion de metanol y/o para regular la temperatura en la zona de reaccion para optimizar las condiciones del reactor; la medicion de la densidad tambien se puede utilizar para ajustar otros parametros en el sistema del reactor; la invencion se refiere a un sistema para fabricar acido acetico basado en el procedimiento de control descrito. |
