Nanobubbles Enhanced Flotation of Oily Produced Water at Large Natural Gas Platform

Abstract

Abstract During petroleum extraction at offshore platforms a large amount of so called "produced water" with emulsified oil is created. This manuscript will summarize our efforts from science behind centrifugal nanobubbles enhanced microbubbles flotation to results of the pilot studies on removal of emulsified oil from produced water. Full – scale installation of treatment system at large natural gas platform will then be briefly described. Flotation Systems need treatment chemicals, coagulants, and flocculants for the best oil removal efficiencies. The synergistic application of nanobubbles enhanced flotation with treatment chemicals will be described.
