Guest editorial: foams in flotation and fractionation
Paul Stevenson has been a Research Academic at the University of Newcastle (Australia) for 6 years. He gaineddegrees in Chemical Engineering from the University of Cambridge, before working as a Japanese ConvertibleBond Trader and an independent Racecourse Bookmaker. He undertook doctoral studies in Cambridge beforeresearching flow assurance problems in subsea oil flowlines for the Consortium on Transient Multiphase Flow.In addition to froth, he has active research interests in welding technology, hydraulic conveying, slug flow,the design of milking machines and the gestation of instabilities in betting markets.
Geoffrey Evans is Professor of Chemical Engineering at the University of Newcastle with research focus onthe interfacial phenomena controlling the behavior of multiphase systems. In particular, his investigations haveranged from bubble break-up and coalescence, emulsion behavior, interfacial mass transfer, through to theinfluence of turbulence on the interaction of bubbles and suspended particles. His work has had applicationsin water treatment, and minerals and metallurgical processing industries. Professor Evans published over 120publications and reports in the area.
Pneumatic froths are a fundamental element in theprocesses of froth flotation and foam fraction. Given theimportance of both the established minerals processingindustry, and the emerging bioengineering sector in theregion, pneumatic foams are thus of special interestto process engineers in the Asia–Pacific zone. Anumber of leading authors in these two fields havekindly contributed fully peer-reviewed papers to thisspecial edition of the Asia–Pacific Journal of ChemicalEngineering.
The call for papers garnered a stronger response fromthe foam fractionation community than it did from frothflotation researchers. This is, we feel, an indicationthat this exciting and emerging technology is startingto gain significant attention, some four decades after
Robert Lemlich’s seminal work in the field. We areconfident that the coming years will see progress madein illuminating the physical processes that underpinfoam fractionation, as well as practical innovation tomake the process truly commercially viable.
