Expert has conducted fluid bed experiments with five different commercial fluid bed processes involving all four types of powders (Group’s A, B, C, & D). His on-hands research involved all types of fluid bed reactor designs from bubbling to riser’s regions for lab unit’s (1 inch X 36 inch), pilot plants (0.5 ft. X 200 ft.), and commercial plants (26 ft. X 250 ft.) His experience involved design, modeling, scale-up, sampling, analytical analyses, safety analyses, procedures, commissioning, start-up, operations and unique solutions. He has patents and publications in the Fluidization field and especially in ammoxidation improvements. Also, Expert has extensive experience in non-fluidize area in hydrogenation and oxidation fields such as purified terephthalic acid (expert witness) and cyclohexanol – cycloxanone (patent). His experience involves scale-ups from lab to pilot to commercial scale operations.

He consulted for a Chinese Engineering Client in comparing their technology to the older PTA, which he helped develop in the 1970’s. His expert witness report in 2011 resulted in favorable settlement for his client.He consulted for a US Saudi Petrochemical branch in the 2000’s to develop the proper scalable fluid bed lab reactor for catalyst development and process improvements. He consulted for a US start-up Energy Company in 2007 to properly set-up fluid bed reactor test guidelines for obtaining scalable data and later assisted in designing and planning a full size pilot plant.He consulted for a US Engineering Company in 2005 to develop guidelines and data acquisition on an existing Pilot unit to obtaining scalable Fluid Bed basic data.
