A Screening Apparatus for Comparing the Fouling Resistance of Heat Exchanger Surfaces

Fouling is a challenge in many processes, especially in heat exchangers and evaporators. Even though many treatments have been developed to mitigate fouling on metallic surfaces, no standardized method exists to compare equipment based on its antifouling performance. In this work, a screening appara...

Summary:Fouling is a challenge in many processes, especially in heat exchangers and evaporators. Even though many treatments have been developed to mitigate fouling on metallic surfaces, no standardized method exists to compare equipment based on its antifouling performance. In this work, a screening apparatus is presented, which allows to compare samples of treated metallic surfaces based on thermal fouling resistance. A parameter screening and a ranking of three differently treated metallic surfaces using two model substances, namely, whey protein concentrate (WPC) and calcium sulfate, are demonstrated. For comparing the fouling resistance on different metallic heat exchanger surfaces, a screening apparatus and corresponding standardizable procedure were developed. Three differently treated metallic surfaces were then tested using two model substances, demonstrating the ability to assess their antifouling performance with the apparatus.
