Process engineering and design consulting for products and systems that involves the handling or processing of solids

Note the size of this project (look for the man in the JLG), which combined three well-known technologies in a novel way to solve a problem at a third of the cost of a conventional system. 


Some areas of expertise are crystallization, drying, filtration and centrifugation, air pollution control, pneumatic conveying, blending and milling, solids separations and agglomeration


Examples from Chemical Engineering Magazine are:

Don't let Phase Changes Faze You, October 2005

Install Pneumatic Conveyors Correctly, April 2006

Avoid Trouble with Slurries, November 2006

Clamp Down on Clumping, October 2009
