ChBE Spring Seminar: Particles Are Your Problems

Event Date 

February 14, 2018 - 3:15pm to 4:30pm


10 W. 33rd Street

Perlstein Hall Auditorium, 131

Chicago, IL 60616


Armour College of Engineering and Biological Engineering Department will host a seminar featuring Ben Freireich Technical, Director PSRI.  He will present his lecture, Particles Are Your Problem.


Billions of pounds of bulk solids are processed and handled every year by the US process industries, yet most undergraduate chemical engineers have never had a lecture, let alone a course, in solids processing. Hence, plants and products suffer with lost production, inability to achieve design production rates, off grade or off specification products. During this seminar, we will take a look at the fun and exciting world of solids processing. Specifically, we will look at some of the more common particle-based technologies examining both the important role they play in society today along with the associated technical challenges.

Short Biography:

Ben Freireich is the Technical Director at Particulate Solid Research, Inc. (PSRI) and previously a Research Scientist in Engineering Sciences at The Dow Chemical Company in the Solids Processing Lab.  He obtained his PhD in Mechanical Engineering in 2010 from Purdue University studying manufacturing processes involving solid materials (particles, powders, etc.).

At PSRI, Ben guides member and contract research efforts executed by the technical staff. PSRI is a consortium-based research company with member companies across the globe that applies and generates fundamental research in the area particle technology with focus on fluidized systems. At Dow he was involved in many products and processes, with expertise on powder flowability, fluidization, size enlargement, attrition, etc.

Ben has over 20 publications and over 250 citations, sits on the Executive Committee of the AIChE Particle Technology Forum, is the Chair of ASTM D18.24 sub-committee on Characterization of Bulk Solids and Powders, and was recently named one of AIChE’s 35 under 35 for 2017. He lives in Chicago, IL and has four children.
