FCC Semiworks  Mobil R & D; Paulsboro, NJ. Lead process engineer in the design and construction of semiworks plant using higher operating temperatures (up to 1500°F) and high alloys to crack higher sulfur-content crude feedstocks. Developed P&IDs, PFDs, mechanical design, and overall control strategy.
Water/Hydrocarbon Phase Separation  Sunoco; Marcus Hook, PA: Lead process engineer; provided process and mechanical design for a retrofit project involving the installation of a passive (gravity operation) water/hydrocarbon separator. Developed equipment sizing and mechanical design; revised existing P & IDs.
Petrochemical  Aromatics stream upgrading pilot plant; Mobil R & D; Paulsboro, NJ: Lead process engineer in the design and construction of fixed bed adsorption units for toluene/xylenes disproportionation. Developed P&IDs, PFDs, pressure vessel designs, overall mechanical design and control strategy.
Fine/Specialty Chemicals  Batch polymer process for manufacture of copier and printing toner; debottlenecking an existing agricultural chemicals process; API facility upgrades; conceptual design for a new PTFE plant; numerous distillation simulation projects; titanium dioxide calcinations.
Environmental  Thermal oxidation of waste streams; VOC emission abatement with vent condensers for solvent recovery; hydrogen sulfide scrubber column design

Mr. Barry holds a BS in Chemistry from the University of Delaware, and an MS in Chemical Engineering from the University of Maryland. He is a registered professional engineer in Delaware and New Jersey and a member of the American Institute of Chemical Engineers and the Chemical Consultants Network. Mr. Barry is a published author, and has a working knowledge of German and French.
