Abstract

DC60 (01/07/41) Method for use in a part-cycle sub-process. Of the hot boiled liquor from the digester before boiling To form a liquid-vapor interface in the digester, and then to separate or blow the vapor over the liquid-vapor interface and to reduce the pressure in the sub. Up to the saturation pressure of hot boiling liquor, the combination of these steps in the process eliminates the adhesion On the fibers found to be Prevent the ability to bleach In this way, a method and equipment for the cycle digestion of the membranes are provided, which provides a Improved purification and rheological characteristics A method for use in a cycle digestion process where part of the hot boiled liquid is separated from the digester before boiling. To form a liquid-vapor interface in the digester and then to separate or blow the vapor over the liquid-vapor interface. And the pressure drop in the sub Until about the saturation pressure of lip Hot Boiled Cure The combination of these steps in the process eliminates the adhesion on the membranes that are found to be self-contained. Prevent the ability to bleach And this implicit fiber flow. Methods and equipment for the circular fiber digestion. Production will be arranged. Which provides a fibrous membrane that has Improved purification and rheological characteristics
