In this work, a dynamic optimization of the fouling process in the Soult-sous-Forêts geothermal plant is being considered using the gPROMS distributed process modeling capabilities. The development of the reaction scheme is based on lab-scale experiments. gPROMS (general PROcess Modeling System) is a simulation tool widely used for creating and executing models of any level of complexity, particularly in areas characterized by complex physical and chemical phenomena as those encountered in geothermal environments. Once an accurate predictive model is available it can be used for many different activities in analyzing and optimizing a wide range of aspects of design and operation. The result is improved design solutions, such as equipment dimensions, control tuning values and set point trajectories, with capital and operational savings that will be realized over the lifetime of the plant. 
The work considers also some of the issues associated with the generation and reliability of the laboratory data used in the construction of the model. The new laboratory scale data have been acquired from a series of tube blocking experiments using nuclear techniques.
