Matthew Walters
Matthew S. Walters, Ph.D., P.E.
Senior Engineer
Thermal Sciences
Warrenville

Dr. Walters’ background is in chemical engineering with specific expertise in the areas of gas treating, process modeling, and process control. He has applied his expertise to a variety of pollution mitigation systems, including post-combustion carbon capture, natural gas processing, refinery tail gas clean-up, and liquid-liquid extraction of contaminants from silicone polymers. Through his graduate and professional experiences, he has become an expert user of the process simulation packages Aspen Plus®, gPROMS®, and ProTreat®. Dr. Walters leverages his knowledge of process systems to provide incident investigation and process safety consulting services.

Prior to joining Exponent, Dr. Walters was a Development Engineer at Optimized Gas Treating, a company that provides software to model gas treating and sulfur recovery processes. His roles at Optimized Gas Treating included expanding the technical capabilities of the software package and providing support to customers in the oil and gas industry. He completed his Ph.D. at the University of Texas at Austin, where his thesis focused on dynamic modeling and process control of carbon capture from power plants using amine scrubbing technology. Dr. Walters was involved with the UT-Austin carbon capture pilot plant and designed dynamic pilot plant experiments for model validation.
