Pressure retarded osmosis (PRO) is a power generation process that harnesses the salinity gradient between two water bodies of different salinities. Using high as draw solution, this work assesses techno-economic feasibility technology to generate electricity using single and multistage systems. This utilizes simulator built on rigorous Q-Electrolattice equation state mass transfer model accoun...

In power generating terms, a pressure retarded osmosis (PRO) energy generating plant, on a river entering a sea or ocean, is equivalent to a hydroelectric dam with a height of about 60 meters. Therefore, PRO can add significantly to existing renewable power generation capacity if economical constrains of the method are resolved. PRO energy generation relies on a semipermeable membrane that is p...

Recent research efforts in taking pressure retarded osmosis closer to commercialization have concentrated on the development of osmosis-specific membranes. The module design, other hand, has not attracted much attention, although need for designs was identified, when traditional desalination were proven unfeasible applications. This work introduces a novel, design. submerged-helical is low pack...
