Senior Principal Development EngineerLummus Technology 1977 - 2011(company changed names/owners: CE Lummus, Lummus Crest, ABB Lummus Global, CB&I, McDermott, now Lummus Technology)Technology leader for "ALMA" maleic anhydride Process development, commercialization, customer service and improvements.Liaison between ALMA R&D and design, between Lummus and ALMA technology/licensing/catalyst partner Alusuisse Italia S.p.A. (became Lonza S.p.A. then Polynt S.p.A.), and between ALMA licensors and commercial plant clients (from marketing through design, construction, startup, operation).Successfully commercialized 7 plants, implemented 2nd generation process improvements, contributed to 4 generations of catalysts commercialized.Process development manager for Lummus Olefin Oxide Process. Technology was based on organic chlorohydrin, including use of tertiary butyl hypochlorite, and incuded issues relating to corrosion and compound stability/safety. It incorporated full recycle of effluents, with spent brine fed to caustic/chlorine plant integrated within process. A subprocess developed was chlorate oxidation to remove impurities from the spent brine.Process development advisor to LKAB (Sweden) shale gasification development program.Contributed to other develop efforts at process concept, economic justification, lab testing and prelim design phases, including- hydrocarbon dehydrogenations (alkanes, olefins, ethylbenzene) ranging from no oxygen to O2 assist (for heat supply with/without other process benefits) to oxidative dehydrogenation (ODH), including close attention to flammability + energy considerations- CO2-enhanced ODH- OxyMethylation of Toluene (OMT) to styrene- paraxylene reactions/ separations- hydroisomerization of alkanes to branched alkenes to increase octane- selective ring opening of naphthalenes- CO2 absorption- propylene glycol from biodiesel byproduct glycerol- fluid-bed gasification of petroleum coke, coal and biomassContributed to planning study for petrochem complex expansion/modernization.
