Conference prizes

P4G members won two of the three poster prizes at the International Conference on Heat Exchanger Fouling and Cleaning held in Enfield, Eire, in early June. Ole Mathis Magens presented his paper on Value pricing of antifouling surface coatings (co-authors Jurgen Hofmans and Martial Paborn of Chemours and Chemours/Du Pont) while Ian Wilson presented work from Vincent Lister's PhD work with John Davidson and Steve Sutcliffe (Huntsman) entitled Management of acute particulate fouling in a titanium dioxide reactor system.

The photo shows Ole and Ian with Paul Watkinson, Ian's PhD supervisor from the University of British Columbia.
