In this commentary, energy analysis was applied on KP process from the veiw point of exergy concept. The energy balance indicated the exergy loss in recovery boiler to be 8056 of the total loss in KP process.
Though the exergy efficiency of KP process is inferior to the other chemical processes, it is difficult to improve the efficiency under the existing pulping process. Utilization of the lignin and other organics burned in recovery boiler is one of the ways to improve the efficiency drastically. The other way is conversion of delignification reagent to, such as, organic solvent which require lower energy for its reuse as lignin extractor than alkali recovery. From this point, organosolv pulping can be a solution to the better energy usage.
