SIMULATION OF KINETIC MODELLING OF CAUSTICIZING REACTOR

Abstract

The final stage of the recovery process is the causticization of green liquor from the smelt dissolve r of the furnace section to reclaim the alkali in. a form readytor reuse in the cooking, cycle. The efficiency of causticizing process does have an important bearing on the overall recovery process. Higher causticizing efficiency means that the circulation of ini,ert chemicals in system is reduced which directly influences the economy and efficiency of the recovery process. An attempt has been made in this work to study how the factors affect causticizing 7efficiency by preparing a model solution of approximately the same composition of Industrial Green Liquor from an integrated Pulp and Paper Industry.
