Ovivo CONESEP (Condensate Polishing Technology for Power Stations) system

Ovivo’s CONESEP (Condensate Polishing Technology for Power Stations) system is a fully automated process for external regeneration of ion-exchange resin, used in deep bed ion-exchange condensate polishing.

The process achieves very good resin separation to conventional external regeneration systems without operator intervention, which is key to high-quality condensate and permits extended runs beyond the ammonia point breakthrough. The externally regenerated technology fully isolates the resin regeneration process and chemicals from the condensate lines, employing full flexibility in resin ratio.

One CONESEP system can service a number of service polishers. It allows for a spare charge of resin to be transferred back into the service vessel as soon as the exhausted resin is removed, to minimise polishing downtime. The system can be easily retrofitted into existing condensate polishing plants.

The system can achieve good resin separation that is independent of the ratio of anion and cation resins used, enabling different resin types to be used. The anion resin in cation resin is <0.1% and the cation resin in anion resin is <0.07%. The resin separation process can be monitored locally.

The system does not require inert resins or three-bed systems to achieve high resin separation levels. Only two vessels are needed. The system can be factory-assembled with breakdown and rebuild kept to a minimum.
