Industrial Fluid Mixing: Engineering Theory and Practice
Virtual Course: 2021 Schedule
December 6th – 9th, Monday through Thursday (1/2 Day Sessions 10AM – 2PM EST)
University level academic lectures lead by PMSL Director of Mixing Technology, Richard K. Grenville PhD.
Complement academic lectures with physical demonstrations of phenomena that have been discussed.
Mixing is an important, sometimes critical operation for the process industries but it is rarely taught in the traditional chemical engineering curriculum. Most engineers are taught the contents of a stirred tank are uniformly mixed and that this happens instantaneously. In some cases, this assumption is valid and in others, when it is not, it can lead to severe problems in the operation of a plant.
Philadelphia Mixing Solutions is offering a four-day course in which the science of mixing will be demystified, providing practical knowledge that can be immediately put into practice. Classes each day will be four hours in length.
Half-day sessions will be conducted virtually and mixing phenomena will be demonstrated via videos produced in PMSL’s world-class lab and test facilities in Palmyra, PA.
Due to the academic nature of the course, its contents will contain theory at a level found in BS level engineering degrees. Process and mechanical engineers will be most familiar with the content; all others with an appetite for interpretive equations are welcome!
After Attending the Course, You Will Be Able To:
- Identify mixing problems and techniques to address them
- Select appropriate impellers to effectively achieve the desired “process result”
- Perform calculations for sizing agitators (power, speed, etc.)
- Discuss process requirements with vendors and assess their proposals
- Identify problems where advanced modelling techniques can be reliably applied and when lab-scale, physical testing should be performed.
- Introduction to mixing
Defining mixing. Characterizing the performance of impellers.
- Blending of low / medium viscosity fluids
Review of common agitator design rules. Estimation of blend times.
- Blending of high viscosity / non-Newtonian fluids
Measurement of viscosity. How viscosity affects mixing. Impeller selection. Estimation of blend times.
- Mixing and chemical reactions
How mixing affects the yield / selectivity of fast, competitive reactions. Lab testing and scale-up. Precipitation.
- Solid-liquid mixing
Degree of suspension versus distribution. Impeller selection and agitator sizing. Mass transfer. Attrition. Feeding and wetting light solids.
- Gas-liquid mixing
Equipment selection. Flooding versus complete dispersion. Impeller selection and agitator sizing. Impeller design for gas draw- down from reactor head space. Mass transfer.
- Heat transfer
Mixing and process side heat transfer. Effect of viscosity. Impeller selection. Overall heat transfer coefficient.
- Mechanical considerations
Design of agitator components. Gearboxes, seal, shafts and impeller blades. Agitator mounting.
- Computational fluid dynamics
What is CFD? The underlying mathematics. Time-averaged versus time-dependent. Validation of code predictions. Examples of “real world” applications.
PMSL is dedicated to mixing, and so is our extensive test lab. Videos of projects in our test lab apply directly to subjects discussed in our lectures.
