In undergraduate courses, we often begin with an assumption of perfect mixing. This assumption does not always apply in real processes. New solutions to long-standing problems can be found when mixing principles are understood and applied. Mixing problems may appear as maldistribution, increased fouling, reduced yield, or increased requirements for additives.

Mixing principles can impact the performance of many systems:
  • Injection of chemicals into pipelines
  • Dumping streams into tanks or ponds
  • Sediment build up in storage vessels
  • Movement or conditioning of slurry (or pulp)

Course Objectives

By the end of the course, participants should be able to:
  1. Identify a mixing problem and break it down into process objective(s), mixing specification(s), and dominant mixing scale(s).
  2. Explain the relationship between turbulence and multi-phase mixing.
  3. Identify paths forward for more reliable scale-up and scale-down of mixing dominated problems.
  4. Apply mixing principles to operational troubleshooting, pinpointing mixing problems and solutions in our units and equipment

Course Outline

Morning

  1. Introduction to mixing – what is mixing and when does it matter? 
  2. How to specify mixing requirements for a process problem
  3. Blend time and large scale segregation of solids and liquids

Afternoon

  1. Micro-mixing and turbulence: emulsions, mixing sensitive reactions, mass transfer limitations
  2. Meso-mixing – effects of local concentrations and competing rates
  3. Scale-down – how to investigate mixing problems at the bench scale

Target Audience

Chemical and Mechanical Engineers

Recommended Text:

Advances in Industrial Mixing, Wiley, 2015. This book includes the Handbook of Industrial Mixing (Wiley, 2004) in searchable pdf format and 21 video tutorials on the basics of mixing.

Suzanne Kresta (BSc, UNB (1986), MSc, Leeds (UK, 1987), PhD, McMaster (1992)) teaches Mass and Energy Balances (CME 265), design (ChE 464) and Mixing (ChE 420 and 620), and serves as Senior Editor of the Handbook of Industrial Mixing. Her principle research contributions are related to understanding turbulence and mixing in stirred tanks (measurement of turbulence, the use of spatial statistics to define mixing and length scales, nano-particle production, solids suspension, reactor design, and additive performance) and she has collaborated with colleagues in a wide variety of industries (including oils sands extraction and froth treatment, photographic film, drinking water treatment, mineral processing and metals refining, polymer reactor design, cosmetics, mixing equipment design, fish processing, clean-up of nuclear waste, and fertilizer production). Many of her papers are both widely cited in the research literature and used for industrial design calculations.

Her teaching interests include faculty development workshops, visual problem solving tools, the use of story telling and case studies, active learning, and explicit use of cognitive levels with learning objectives. She has served as an Iron Ring Warden since 1999, as a Peer Consultant at the University of Alberta since 2004, and has won a number of national and international awards for both teaching and research.
