Electrodialysis may be an alternative to RO or evaporation. As with RO you will end up with a concentrate stream and an essentially salt-free diluate stream. Electrodialysis may be economically favorable depending on the price of electricity. You will have to do some long term experiments in...
As toluene and water are immiscible, the vapor pressures of toluene and water in the vapor phase above the two-phase mixture of liquid toluene and liquid water will establish themselfes independently. That is, at a given temperature, the total pressure will be the sum of the vapor pressures of...
