*User can set up the unit for solvent extraction or organic stripping. The model also allows imperfect separation of products, to do this, specify aqueous loss in organic and/or organic loss in aqueous. | *User can set up the unit for solvent extraction or organic stripping.

*User is responsible for setting up a suite of species which accurately portrays the application that is being evaluated. As the separation of the mixture will be based on individual phase or density, we recommend defining all aqueous species with individual phase (aq) and all organic species with individual phase (o). If using separation by density, please ensure the organic species are defined with a lower density than the aqueous species. | *User is responsible for setting up a suite of species which accurately portrays the application that is being evaluated.

*This requires the specification of appropriate data for organic-aqueous exchange reactions within the {{{TPS}}} database. These are typically determined using pure system shakeout tests. As an example, contacting fresh extractant dissolved in diluent at a known concentration with pure metal chloride salt solution over a range of organic/aqueous ratios would provide suitable data for fitting. Knowledge of the extraction and stripping mechanisms are required to successfully fit the equilibrium values required to model the reactions. | *This requires the specification of appropriate data for organic-aqueous exchange reactions within the {{{TPS}}} database.

*We have experience in generating appropriate data inputs and can provide simulation services to clients as required to generate appropriate models. Examples of conference papers we have written on this topic can be provided upon request. | *We have experience in generating appropriate data inputs and can provide simulation services to clients as required to generate appropriate models.
