A novel power recovery system, immiscible fluid engery recovery device (IFERD), for reverse osmosis desalting plant was investigated. Conceptual designs and cost estimates were developed for two commercial-sized seawater reverse osmosis desalting plant applications. An economic evaluation of the IFERD system when compared to conventional power recovery devices shows the IFERD system to be more economically attractive in most cases, except when power costs are extremely low. This is mainly due to its superior efficiency in both the recovery of energy and the application of the recovered energy. In addition, the IFERD system offers potentially increased reliability and reduced maintenance. Recommendations are made for pilot testing to demonstrate the performance and reliability of the IFERD system and to obtain other data necessary to developed the IFERD system to the point of commercial use.
