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. Recovery of kraft black liquor using the titanate process : a study of the leaching reaction of 4:5 sodium titanate
Sammanfattning : .... LÄS MER
5. Recovery of kraft black liquor using the titanate process : kinetics of the direct causticization reaction between sodium tri-titanate and sodium carbonate
Sammanfattning : The solid state reaction between sodium tri-titanate and sodium carbonate, forming mainly sodium penta-titanate, was investigated. Experiments were carried out in a micro-differential reactor made of quartz glass at various temperatures between 800°C and 880°C and in a pilot fluidized bed reactor operated in a semi-batch mode.
