Abstract: The expressions of heat of evaporation for metals at different temperatures were de-duced from Clausius-Clapeyron eyuatian and the total change of enthalpy. Those of Pb, Cd and Zn were calculated. Results showed that theoretic energy consumption decreased a little with the decrease of e-vaporatian temperature, which can be used to determine the energy demand while these metals are dis-tilled at different process temperatures and pressures.
