Solved: 3. Evaporation Energy Balance Evaporation Is Commo ...

Evaporation Energy Balance Evaporation is commonly used to concentrate a feed stream by evaporating water, resulting in an increase in the concentration of the solid dissolved in solution. Heat required to vaporize the water is provided by steam that flows through a tube inside of the evaporator, with saturated steam fed to the evaporator and saturated liquid exiting the tube from the evaporator.

1 Fundamentals of Energy Analysis of Dryers

supply the latent heat of evaporation to remove the water or other solvent. There are thus clear incentives to reduce energy use in drying: to conserve finite resources of fossil fuels, to reduce carbon footprint and combat climate change, and to improve process economics, but it is a challenging task facing real thermodynamic barriers.

Chapter 8 and 9 – Energy Balances

Recall that enthalpy and internal energy are always defined relative to a reference state (Chapter 7). When solving energy balance problems, it is therefore necessary to define a reference state for each chemical species in the energy balance (the reference state may be predefined if a tabulated set of data is used such as the steam tables).
