This chapter discusses the operation of marine water distillation systems with emphasis on the problems associated with scale deposits in heat exchange components. The chapter emphasizes the detrimental effects of scale deposits on energy consumption, thermal conductivity, and overall performance of heat exchange surfaces. To address these problems, the article discusses chemical cleaning methods that can effectively control scale deposits. The importance of maintaining optimum operating conditions, controlling solvent concentration, and performing chemical treatment to improve heat transfer efficiency in a distillation unit is emphasized. The effect of scale thickness on fuel consumption and subsequent increase in operating costs is also discussed. The chapter proposes an integrated approach to scale control in seawater distillation systems, combining proper design solutions, operating parameters, and chemical treatment strategies to improve performance, reduce energy consumption, and extend equipment life, providing sustainable and efficient desalination in marine environments.
