Abstract
Procedimiento para la limpieza de membranas porosas adecuado para uso en procesos de refinado de aceite, el cual comprende el tratamiento regular de dichas membranas mediante la aplicación de la etapas de: a) retrosoplado con gas cuando el flujo se ha reducido a menos del 95 % del flujo máximo, es decir, el flujo a través de la membrana inmediatamente después de la limpieza; b) retroflujo con aceite comestible, cuando la velocidad del flujo máximo medido después de retrosoplado con un gas, ha disminuido a menos del 90 % del flujo superior, es decir, el flujo a través de la membrana cuando esta se usa por primera vez; c) tratamiento de las membranas con material alcalino cuando la velocidad del flujo máximo medido después de retroflujo con aceite, ha disminuido a menos del 90 % del flujo superior; en el que el procedimiento se usa para una limpieza in situ, con la condición de que dicho procedimiento no implique el uso de disolventes orgánicos para limpiar las membranas.
