Abstract

La presente proporciona un sistema de control automático, un método y una máquina de fabricacion de papel que usa dicho sistema de control para controlar automáticamente la cantidad de eliminacion de agua en una seccion de prensa por medio de la aplicacion medida de agentes químicos de eliminacion de agua aplicados a una red de papel en un proceso de fabricacion de papel. El sistema de control incluye un controlador de retroalimentacion para controlar la cantidad de agente químico de eliminacion de agua aplicado a una red de papel, y un dispositivo de monitoreo para obtener una medicacion de la humedad de la red de papel que sale de la seccion de prensa.
