SYNTHESIS AND ANALYSIS OF PROCESSES WITH ELECTROLYTE MIXTURES

A computer aided system for synthesis, design and simulation of crysta llization and fractional crystallization processes with electrolyte mi xtures is presented. The synthesis methodology is based on the use of computed solubility diagrams for the corresponding electrolyte systems . For a specified crystallizer and product(s), the process flowsheet a long with conditions of operation is determined while for a specified feed mixture and product(s), the process flowsheet together with the t ype of crystallizer is determined. In order to verify the ''determined '' flowsheet an option to perform steady state simulation is also prov ided. Examples highlighting the various features of the, computer aide d system are presented.
