Flowchart for implementing superstructure optimization approach

The recommended flow path for optimizing solvent recovery processes using the superstructure approach. The diamond-shaped decision box is implemented via binary (1-yes/0-no) selection variables, which then enables the logical flow constraints for active/inactive technologies and their corresponding stream flows.
