Abstract
Saudi Arabia has the largest capacity of desalination inventory in the world. Desalination in Saudi Arabia account for approximately 50% of the world capacity. In these massive desalination plants, huge amounts of drained brine are disposed. Besides the large flow rates of the disposed brine, sea water intakes in Saudi Arabia, Red Sea and/or Arabian Gulf, have the maximum salinity in the world. This increases the amount of the dissolved minerals in the desalination blow-down. The use of drained brine in appropriate processes can yield magnesium, calcium, potassium, chlorine and bromine as well as salt, sodium chloride. The possible production of some by-products from Saudi desalination plants will be discussed in this paper together with the technical feasibility of the proposed processes.
