Technical papers addressing the topics of heat exchanger fouling and cleaning are sought for the Eurotherm International Conference on Heat Exchanger Fouling and Cleaning. The biennial event is scheduled for June 14 to 19, 2009, in Schladming, Austria, near the city of Salzburg.

Heat exchanger fouling in the process industries is a chronic operating problem. Costs due to overdesign, additional fuel consumption and maintenance, loss of production, and other factors have been estimated as 0.25 percent of the GNP of industrialized countries. In addition to the appropriate selection of operating conditions and exchanger geometry, there are numerous chemical and mechanical methods to mitigate fouling and to remove deposits from the heat transfer surfaces. However, all methods to reduce fouling require some understanding of the mechanisms of the deposition process and of the structure and adhesion of deposits on the heat transfer surfaces.

Key themes of Heat Exchanger Fouling and Cleaning 2009 are:
  • Crude oil and hydrocarbon fluid fouling.
  • Fouling in industrial processes and power plants.
  • Fouling in the dairy and food industries.
  • Fouling in thermal desalination plants.
  • Mechanisms of heat transfer fouling (crystallization, particulate, reaction, corrosion, solidification and biofouling).
  • Surface and chemical treatments.
  • Micro and compact heat exchanger fouling.
  • Fouling mitigation and cleaning (chemical, mechanical and physical techniques).
  • Heat exchanger fouling monitoring.
The conference is intended to facilitate innovative thinking and to explore theoretical and practical approaches to address the challenges associated with heat exchanger fouling. Technical presentations as well as industrial case studies, whether there have been successful solutions to fouling or not, are sought as a means to encourage discussion.

Abstracts are due December 1, 2008. Authors of accepted papers will be notified on December 15, 2008. Full-length manuscript are due March 31, 2009.

Both oral and poster presentations will be scheduled. Potential participants can submit a one-page abstract (maximum 250 words) for consideration to Dr. Reza Malayeri of the Institute of Thermodynamics and Thermal Engineering, University of Stuttgart, Stuttgart, Germany, by sending an e-mail to
