Offshore Processing of CO2-Rich Natural Gas with Supersonic Separator

- Prof. Dr. Ofélia de Queiroz Fernandes Araújo: She holds a PhD (1987) and MSc (1984) degrees in Chemical Engineering from the University of Illinois at Urbana-Champaign (USA), and BSc in Chemical Engineering from the Federal University of Rio de Janeiro (1981), Brazil. Worked at NATRON SA (1987-198) and OXITENO SA (1989-1993) in process simulation and control engineering. Joined the Federal University of Rio de Janeiro, in 1993, in the Chemical Engineering Department, where she is currently Associate Professor. Her research interests are process and environmental engineering, with special focus in natural gas processing, and CO2 separation and utilization, and green engineering. She was head of two graduate programs - Technology of Chemical and Biochemical Processes (2007-2010) and Environmental Engineering (2014-2015).
