Demineralised Water Treatment System

The demineralised water treatment system receives water from the raw water system, processes this water to remove ionic impurities and provides demineralised watertothe demineralised water transfer and storage system. The system consists of two reverse osmosis feed piunps, two 100-percent reverse osmosis units normally operating in series for primary demineralization and one electrode ionization imit for secondary demineralisation. 

No design requirements associated with maintaining safety functions are placed on the demineralised water treatment system. 

The turbine island chemical feed system injects the required chemicals into the condensate, the feed water, the auxiliary steam, the service water and the stored demineralised water treatment. It is entirely located in the turbine building. 

The reactor effluent comprises gasoline, water and gas. The water is the primary feed to the effluent treatment plant. Detailed studies have shown that it will be feasible to return the waste water to the reformer saturators thereby re-using the waste water and recovering the oxygenates. As a consequence the load on the demineralisation unit and the effluent treatment system will be reduced and the overall efficiency of the plant marginally Improved. Detailed design of this enhancement has now been completed and installation is in progress.
