Theoretical and experimental studies of absorption-driven multiple-effect evaporators were carried out. Theoretical predictions for such units were compared with existing industrial-scale conventional evaporators. It was calculated that the total energy consumption of an absorption-driven evaporator is considerably lower than that of a conventional multiple-effect evaporator. Theoretical predictions were also verified with an experimental four-effect absorption-driven evaporator, coupled with a two-effect regenerator, using sodium hydroxide solution as the absorptive medium. Energy savings of 30 % to 45 % were obtained.
