METHOD FOR HYBRID GENERATION OF ELECTRICAL POWER USING SALINITY GRADIENT OF SALT WATER AND FRESH WATER AND HYBRID GENERATION SYSTEM OF ELECTRICAL POWER USING SALINITY GRADIENT OF SALT WATER AND FRESH WATER USING THEREOF

摘要

The present invention relates to a hybrid power generation method using the salinity difference between the saltwater-freshwater, in the hybrid power generation method using the salinity difference between the saltwater-freshwater, in the brine, by reverse osmosis, a part of the fresh water contained in the brine Reverse osmosis desalination step of separating; And an osmosis power generation step of producing electric power by using the flow rate increased by the osmotic pressure generated by the concentration difference between the brine and the brine that has undergone the reverse osmosis desalination step. According to the present invention, unlike the prior art, by effectively combining reverse osmosis (RO) and pressure delayed osmosis (Pressure Retarded Osmosis, PRO), not only can the power production and desalination proceed in one process, Since the chemical energy of the high concentration brine flow discharged from the reverse osmosis desalination process can be utilized for power generation, there is an advantage to maximize energy efficiency.
