Course Description

This intensive two-day course introduces participants to all the important scientific, engineering, and operating aspects of Selective Catalytic Reduction (SCR) and CO/VOC oxidation catalyst systems. Dual Function catalysts are covered.  The course focuses on the commercial and practical experience of these technologies and their operators and suppliers. This information is essential in formulating and evaluating emissions control strategies and system designs. The instructors have firsthand experience in designing, troubleshooting, and servicing NOx and CO/VOC control units for gas turbines, utility boilers, IC engines, and oil-fired heaters. Their experience in Process Design, Control Systems, Reaction Engineering, and Catalysis covers several decades.
