Resumo (PT): Parametric pumping is a cyclic process that allows purification of industrial wastewaters without spending chemicals for regeneration and therefore avoiding a new pollution problem. The applicability of this technology to the purification of salicylic acid in liquid phase has been studied, salicylic acid being a phenolic compound with a high production in a world scale which is mainly linked to aspirin manufacture. The aim is to get at the same time a purified and a concentrated stream of salicylic acid, which allows recycling for the industrial process so contributing to achieve the concept of a zero-pollutant plant. Different operating conditions were accomplished in an automated pilot plant and experimental results were compared to those simulated by a previously developed package (Davesac et al., 2000). A satisfactory agreement is obtained with the linear driving force and axial dispersion model.
