Process Drying PracticeUsing graphs, calculation models and step-by-step guidelines, the authors describe the important tools and techniques and explain how to use them to perform scale-ups and calculate exposure times, to test dryers and study the relationship between drying processes and dryer characteristics, to analyze psychometric charts, to utilize calculation methods for process drying any solvent in any gas, and to overcome complications in the start-up phase and troubleshoot the cause of low production in drying systems. |
