2009 Chem Show Education 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

• Sample collection, splitting, and analysis
• Solids flow problems, such as no flow and segregation
• Flow patterns within a bin or blender
• Effects of bin and blender design on flow patterns
• Common mechanisms of particle segregation

• Valves 101 starts with a broad overview of the valve industry and some of its rich history, and then narrows its focus on key elements such as valve standards, basic piping information and application issues that are critical to effective valve specification and usage. Detailed discussions of the major valve types, including gate, globe, check, ball, butterfly, plug, control and pressure relief, will give attendees valuable knowledge that can be applied in their daily PVF work, whether in sales, as a specifying engineer or an end-user.
• Actuators 101 begins with a description of the various actions, such as linear, rotary, etc., that are employed to operate the valve types discussed in Valves 101. The presenters will then describe the actuator types, such as electric, pneumatic, hydraulic, etc., which provide these actions. Each actuator type is defined in expanded detail to impart an understanding of their variations, characteristics and relative technical matters. Actuators 101 stops short of recommending the optimum actuator selection for a user's application, but it does provide sufficient information to enable users to be aware of their options and to gain a firm understanding of how each actuator type may apply to their specific needs.
