2009 Chem Show AIChE Day Schedule

What will be covered in this session?

• Typical bulk solids flow problems in silos, bins, and hoppers
• Results of flow problems
• Flow patterns and different hopper designs
• Ways to characterize flow properties (common tests and resulting data)

Representatives from the Center for Sustainable Technology Practices will illustrate the use of the Sustainability Guide which illustrates how sustainability practices can be implemented into all operating functions in the Chemical Processing Industries. The guide is a tool designed to promote organizational learning towards sustainability. It promotes collaboration between critical corporate functions as well as provides general guidance and specific sustainable checklists. The Guide was developed by an industry consortium including BASF, Cytec Industries, Dow Chemical, Shell Chemical, Air Products, FMC, and Honeywell.

This course presents an integrative approach for crystallization process development - using models to analyze the SLE behavior of the system, validating the model using relevant experimental data, and systematically synthesizing a crystallization process based on the SLE behavior. Starting with fundamental issues such as solubility and physical properties, we will discuss the relevant theories, methods, experimental techniques, and software tools that have been used in many industrial applications for developing an optimum crystallization process. Such an approach is in line with FDA's PAT initiative, which underscores the importance of understanding of the process in achieving an optimized operation that ensures quality outcomes.

What can you expect to learn?

• How to analyze solubility and SLE phase behavior for the purpose of conceptual design of crystallization processes
• How to use the knowledge of SLE phase behavior in synthesizing crystallization processes and defining the optimum processing conditions
• How to apply fundamental understanding and integrate synthesis, analysis, and experimental effort in developing crystallization processes
• How to solve practical industrial problems in the chemical, fine chemical, and pharmaceutical industries using the integrative approach
