Seawater desalination by parallel feed multiple-effect evaporation has a simple layout in comparison with other multiple-effect or multistage desalination systems. Several operating configurations are analyzed, including the parallel flow (MEE–P), the parallel/cross flow (MEE–PC), and systems combined with thermal (TVC) or mechanical (MVC) vapor compression.
All models take into account dependence of the stream physical properties on temperature and salinity, thermodynamic losses, temperature depression in the vapor stream caused by pressure losses and the presence of non-condensable gases, and presence of the flashing boxes.
