“…The group also proposed a model and validated it through the obtained experimental data [104]. Such HEs were also studied in eutectic freeze crystallization [105,106]. If possible, it is preferable to consider the implications of fouling in the design process already, while also adding mitigation and cleaning strategies on top of that for maximum effect.…”

A vast majority of heat exchangers suffer from unwanted deposition of material on the surface, which severely inhibits their performance and thus marks one of the biggest challenges in heat transfer. Despite numerous scientific investigations, prediction and prevention of fouling remain unresolved issues in process engineering and are responsible for large economic losses and environmental damage. This review article focuses specifically on crystallization fouling, providing a comprehensive overview of the state-of-the-art of fouling in heat exchangers. The fundamentals of the topic are discussed, as the term fouling resistance is introduced along with distinct fouling behaviour, observed in laboratory and industrial environments. Insight into subsequent phases of the fouling process is provided, along with the accompanying microscale events. Furthermore, the effects of fluid composition, temperature, flow velocity, surface condition, nucleate boiling and composite fouling are comprehensively discussed. Fouling modelling is systematically reviewed, from the early work of Kern and Seaton to recently used artificial neural networks and computational fluid dynamics. Finally, the most common fouling mitigation approaches are presented, including design considerations and various on-line strategies, as well as off-line cleaning. According to our review, several topics require further study, such as the initial stage of crystal formation, the effects of ageing, the interplay of two or more fouling mechanisms and the underlying phenomena of several mitigation strategies.

“…It was reported that the heat and mass transfer coefficients were enhanced up to eight times higher than for the case without particles [9,10]. P. Pronk [11] investigated the crystallization fouling prevention in the process of eutectic freeze crystallization by employing the technology of solid-liquid fluidized bed heat exchangers. He reported that fluidized beds are able to prevent salt fouling during cooling crystallization from KNO 3 or MgSO 4 solutions.…”

“…The formation of an insulating scale layer on heat exchanger (HE) surfaces is a common problem in cooling and melt crystallization (Rao and Hartel, 2006;Pronk et al, 2008;Qin et al, 2006). The higher supersaturation close to the HE surface compared to the supersaturation in the bulk solution is the main cause of this phenomenon (Pronk et al, 2005).…”
