A Generic Framework for Modeling, Design and Optimization of Industrial Phosphoric Acid Production Processes

In this work we address the systematic and environmentally efficient design of phosphoric acid production processes through a generic modelling and optimization framework. The employed framework aims to facilitate the design of phosphoric acid production schemes that improve the performance of existing industrial processes while accounting for a number of operating, economic and environmental design options. It is built upon an iterative design strategy, hence allowing the generation and exploitation of useful design insights. Generic process modules are used for the representation of the processes involved in order to facilitate design variability and flowsheet interconnectivity. The beneficial effects of the employed framework are demonstrated through an extensive case study of industrial interest. Designs of improved performance are proposed while the prospect of integrated phosphoric acid production and phosphogypsum utilization is investigated.
