The heat of evaporation can be calculated from the following equation that is valid over a very wide temperature range : from 10 deg. Note that in general the total heat duty by the exchanger consists of the condensation heat released plus the de-superheating of the incoming steam if applicable and the sub-cooling duty of the exiting steam condensate. To calculate the heat exchanger’s ‘duty’ (in kWatts) one need the heat of vaporization/condensation at the particular temperature the exchanger is working at. The steam’s heat of condensation in the equipment is exchanged with the process stream. For example when one needs to determine the duty of an exchanger heating a process stream with steam. This post features short and handy equations for the heat of evaporation DeltaHvap for water (steam condensate) as a function of (saturation) temperature.
