✦ Synopsis
A simple equilibrium theory has been formulated soley in terms of wave interactions for binary pressure swing adsorption-solvent vapor recovery (PSA-SVR). An analytic resolution of all the ensuing wave interactions, including shock wave interactions with compressive simple waves, has been obtained for the case of the separation of the lighter impurity, i.e. the case of recovering the lighter impurity during the feed step, while obtaining a stream enriched in the heavier impurity during the purge step. Analytic expressions have also been obtained for all the key process performance indices. Two conceptual process designs have been carried out that demonstrate the utility of these simple expressions for rapid elucidation of binary PSA-SVR separation process heuristics, performance and feasibility.
