Solvent selectivity adsorption-energy dependence

Concentration (or isolation) tasks are usually necessary wifli streams where the product concentration is very low (dilute). Adsorption and extraction are typical technologies utilized here. Energy considerations dominate the technology selection subject to product contamination and stability constraints. Thus, the base technology depends on the availability of the Mass Separating Agent (e.g., adsorbent or solvent) and its efficient recycle. Supercritical extraction of organic compounds from aqueous streams is a typical example of isolation step.
