Recausticizing Material Balance Equations Relating to Digester Requirements, Technical Information Paper TIP 0418-02 (2024)

One of the objectives of the Process Engineering Committee is to provide information and instructions for the various pulp and paper making systems and equipment to assist management and the pulp and paper mill engineer in specification, evaluation and design of pulp and paper mill facilities.  Particularly, such information will show the interrelationships within and between systems.

This TIP shows the material interrelationships within the recausticizing system as well as between it and the digester system.  Specifically, it lists all the major material balance equations for the recausticizing system, starting with the smelt stream from the recovery furnace and continuing through the white liquor stream to the digester.  All equations relate to only a few independent variables from the digester and recausticizing operations.
