Abstract:
1. A system for purifying an organic solvent fluid and supplying the purified organic solvent fluid to a fluid outlet, the system comprising: a fluid flow pathway including an organic solvent fluid supply source that supplies organic solvent fluid to a vessel containing an ion-exchange media having electrically charged species that ionically interact with metallic and ionic impurities in the organic solvent fluid such that these impurities are removed from the organic solvent fluid as the fluid passes through the ion-exchange media, the fluid flow pathway further including a return chemical flow pathway that facilitates recirculation of the purified organic solvent fluid through at least a portion of the fluid flow pathway, thereby enabling passage of the organic solvent fluid through the ion-exchange media multiple times and thereby facilitating incremental purification of the organic solvent fluid until a desired level of purity is achieved.
