Advantages and Disadvantages of Chloride Process compared to Sulfate Process Advantages Pros

utilization Direct and stable process control Better product quality regarding the optical and

circumstances Less environmental impact due to less waste Less man power necessary Higher

Higher requirements to the qualification of the staff Requires stable production environment

11 Advantages and Disadvantages of Chloride Process compared to Sulfate Process Advantages Pros Disadvantages Cons Continuous Process: Good prerequisites for optimization of quality and utilization Direct and stable process control Better product quality regarding the optical and chemical properties In general, the production costs are lower, but in depends on the special circumstances Less environmental impact due to less waste Less man power necessary Higher safety requirements due to the use of Cl2, CO and TiCl4 Higher degree of automation necessary Higher requirements to the qualification of the staff Requires stable production environment and infrastructure Because of the closed loop the process is more sensitive to production short-fall Page 11
