Abstract: . . .  Experimental studies aimed at understanding basic distillation phenom- ena should account for mixing, interfacial area, mass trans- fer, multi-phase flow, non–air/water systems, and packing/ trays. Comprehensive computer models based on funda- mental phenomena are needed to predict mass transfer 24 Vision 2020: 2000 Separations Roadmap Page 33 and hydrodynamics in distillation columns. Databases for fundamental physical properties and bubble-formation mechanisms will need to be developed for “difficult, com- plex” distillation systems before computer models for these systems can be developed.

A second priority group includes research to predict perfor- mance of retrofitted equipment and to eliminate third phases and unwanted reactions. Workshop Scope: For the purposes of the workshop “extraction,” when used as a separations technology was deemed to apply to liquid–liquid systems. Participants chose to exclude leaching as part of liquid/liquid extrac- tive processing; this should be considered as a separate topic area for a future workshop. Participants also chose to include supercritical extractions that do . . .

The complexity of the chemical industry, with tens of thousands of different products, suggests that a chemical industry needs an atlas of roadmaps covering various technical areas, rather than a single roadmap, to define the path to implementation for Vision 2020 . The creation of an atlas can be approached in a number of ways and, with this in mind, the Council for Chemical Research and the American Institute of Chemical Engineers created a task force to coordinate roadmap development activities. . . .
