Robert Silver (original) (raw)

Robert Simpson Silver CBE, MA, Ph.D, D.Sc., D.Tech, F.I.Mech.E, F.Inst.P, FRSE (1913–1997) was a Scottish physicist and mechanical engineer, awarded the Unesco Prize for Science in 1968 for his discovery of a process for the demineralisation of sea water. Prior to his work there had been no commercially viable desalination process that involved continuous flow; plants had to be stopped and emptied of accumulated salt from time to time, such as when a passenger liner using desalination was in port. Silver performed a thermodynamic analysis (now known as "Second Law Analysis") showing that reverse osmosis and "multi-stage flash" were the optimal processes for purification of water. As reverse osmosis technology was less advanced in the mid-20th century he designed multi-stage flash equipmen
