Abstract/Summary A steady state simulation of the gypsum crystallization section of a hemihydrate/dihydrate wet phosphoric acid process has been developed. For given inlet process conditions, the model predicts the steady state process conditions, including the mean crystal size and size distribution. Using approximate kinetic relations, an analysis has been made for a simple flowsheet with a splitter giving solids recycle. This indicates that there is little scope for process improvements using the available operating variables. However by replacing the splitter with a clarifier or a classifier/clarifier combination, significant process improvements could be attainable.
