The article describes a typical procedure for the industrial implementation of a melt crystallization project starting with pilot testing to determine feasibility and the major design parameters followed by the engineering, construction and start-up of the unit. The presentation is attempting to provide a summary overview about how crystallization theory is included in the design of an industrial melt crystallization plant. A time accelerated sequence of photos will be used during the presentation to illustrate the progress of the construction works during the completion phase. The melt crystallization plant consists of a single stage suspension crystallization unit with external heat exchangers and a separate mixing vessel to provide the necessary residence time for crystal growth. The crystal separation is efficiently accomplished in a wash column where the crystals are counter-currently washed in order to achieve the required high purities. This process is referred to as SCWS (Suspension Crystallization Wash-column Separation) process.
