Achieve technology advancement through economic evaluation, R&D, scale-up, process/technology design, marketing, commercialization, training, startup, troubleshooting and process improvement, with high dedication to customer satisfaction.Perform consulting for short or extended periods, in USA or internationally, especially for catalytic fluidized-bed and fixed-bed reactors (including highly exothermic) and associated processes, in chem processing, energy and renewable industries. Have 10-year multiple entry visa for China (but no recent trips to China due to COVID-19 restrictions); have full Moderna vaccination plus three boosters as of September, 2022, so no personal travel obstacle.Since 2011, doing consulting and process/technology design work for multiple projects, including innovative new maleic anhydride plants and for other technologies and catalyst developments/ process designs/operations in China, Canada and elsewhere.During 2012-2014 helped Infineum (joint venture of ExxonMobil and Shell) at Bayway Chemical Plant in Linden, NJ, in troubleshooting, improving, optimizing, debottlenecking, and expanding various process units for petroleum fuel additives. Had "TWIC" card (for USA harbor industrial plant security).During 2014-current have been catalytic process consultant for New Solar Catalysts (NSC) Co. in Changzhou, the leading catalyst manufacturer for several technologies in China and outside. Has included successful developments and commercializations of both fixed-bed and fluid-bed catalysts.Includes process consultation, training and operation improvements to the NSC client operating companies for reactor and associated plant systems.Since 2017 have been Chief Technical Advisor for DIFREX LLC NEXGEN Reactor Design.During 2016-current, have provided technology and project development consulting services to several confidential companies in Canada.

Cape Canaveral, Florida, Us

Began position in 2017, as Chief Technical Advisor for small “startup company” offering wide range of reaction and reactor services, from conception, through development, modeling, design, scaleup, commercialization and beyond. In tasks where applicable, DIFREX utilizes GRM (General Reactor Model) developed by company founder and CEO, S. Dutta, and under continuous maintenance.Have led DIFREX publicity activities involving exhibits and papers/presentations at various conferences.Team participant in responses and proposals (and future work) for potential clients.

(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.

Did process design, improvement and economics work in hydrodesulfurization, catalytic reforming and FCC (fluid catalytic cracking), including- improved deactivation correlations- new hydrodesulfurization correlations- improved hydrodesulfurization operating procedures- new high-temperature FCC regeneration- FCC of atmospheric resid feedstockLed field tests at conditions before and after the improvements.Coordinated troubleshooting efforts to bring off-spec jet fuel back on-spec.Was a process advisor for check-out and start-up of major grass-roots petroleum refinery, with extra responsibility for overseeing hydrodesulfurization process units and catalysts.Performed technical service, providing answers to refiners' questions regarding their FCC units.
