Successfully Scale Up Solids Handling

Fluids and Solids Handling
K. Eric Bengtson, John W. Carson, Thomas G. Troxel
A sound theoretical model of the process to be scaled is the best approach; if one is not available, bench-scale testing, physical scale modeling or full-scale modeling is required. Here are guidelines as to which method is appropriate for various...

Designing Suspension-Mixing Systems

Fluids and Solids Handling
Pavel Ditl, Frantisek Rieger
Impeller and vessel geometries are key factors in selecting mixing equipment to efficiently suspend particulate solids in slurries

Cut Agitator Power Costs

Back To Basics
Gregory T. Benz, P.E.
Agitator power consumption can be minimized by judicious equipment selection and careful operating procedures. Follow these guidelines to reduce your plant’s energy costs. In some cases, it may be as simple as flipping a switch.

Solid-Liquid Separation: A Guide to Centrifuge Selection

Back To Basics
Tom Patnaik
Centrifugation is a necessary step in many pharmaceutical and chemical production processes. These guidelines will help chemical engineers better understand the process of centrifuge selection.

Selecting In-Process Particle-Size Analyzers

Fluids and Solids Handling
Paul Barrett
To select the proper instrument for process monitoring, one must determine what attribute of the particle system impacts the process or product parameter of concern. Once the size region is identified, it can be tracked in-process, opening up the...
