Solid Salt Sedimentation in Heat Exchangers and the Sedimented Salt Removing Methods

In the present study, the problems of salt solution sedimentation on heat exchangers, their modelling procedure, and the heat exchanger fouling removal methods based on the related published investigation are reported. The salt solutions are used in many technological industries, and the sedimentation of stable salts is the main limitation of using them, especially in the high-temperature liquid-vapor system. The methods of these salts removing is online and offline fouling cleaning. Each of these methods has their advantageous and disadvantageous. In the practical application, there are multiple criteria considering different conditions. Although, based on the heat exchanger design condition, the solid salt sedimentation decrement can be improved the system fouling problems.
