2. Recovery of Kraft Black Liquor - Alternative Processes and System Analysis
Sammanfattning : Besides the conventional recovery process, there are several possible processes whereby the cooking chemicals in kraft black liquor can be recovered. A part of one of the possible processes, direct causticization using titanate, has been studied in detail. LÄS MER
3. Recovery of kraft black liquor with direct causticization using titanates
Sammanfattning : The feasibility of direct causticization of kraft black liquor using titanates has been evaluated. This has been done by studying the kinetics of the reaction between sodium tri-titanate and sodium carbonate and describing the kinetics by appropriate reaction models. LÄS MER
4. Lime Mud Reburning. Properties and Quality of the Lime Produced
Sammanfattning : It is of utmost importance that the white liquor used in the digester of a sulphate pulp mill is of high quality. The white liquor is prepared in the causticizing plant, through causticizing of the sodium carbonate in the green liquor. LÄS MER
5. Disintegration of Lime Mud Particles during the Causticizing Operation
Sammanfattning : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. LÄS MER
