“…Compared to singular modes of fouling, the combined mechanism produced deposits with lower adhesion strength. Zhang et al [68] ran particulate and composite fouling experiments in four commercially available corrugated plate HEs of different geometrical designs. Particulate fouling was found to enhance crystallization and vice versa when both mechanisms were present at the same time.…”

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.

“…Therefore, it is necessary to study the factors that affect fouling in plate heat exchangers. Among various fouling mechanisms, crystallization fouling is dominant for the reduction in the thermal efficiency [3][4][5][6]. It takes places when water soluble salts, predominantly calcium sulphate, become supersaturated on the heat transfer surface.…”

“…Due to their great quantity in chemical plants and the high susceptibility towards fouling, a lot of studies focus their investigation on heat exchangers. As for particulate fouling, the impact of process parameters like flow velocity, process pressure or heat flux were investigated as well as material properties such as particle size or concentration for the foulant or surface modification for the equipment [9][10][11][12]. Apart from the apparatuses, pipe fittings are another group of plant components that have to be considered with respect to fouling.…”

A prominent example of unwanted accumulation in production plants is particulate fouling, which has been subject of many studies in apparatuses. However, pipe fittings have attracted little attention despite their large number in production plants. Here, the influence of process parameters and geometry factors on the fouling in pipe fittings is investigated under isothermal conditions that aims to an improved understanding of their fouling behavior. The variation of fitting type and size, the run time and particle mass fraction have the greatest impact on the fouling mass while the temperature does not influence the result.
