This paper presents a computer simulation model based on the Runge-Kutta 4th-order method to solve the energy balance equations for a multi-basin inverted absorber distiller unit. The effect of reuse of latent heat from vaporization from respective lower basins on daily yield has been studied for optimization of number of effects. It has been observed that when the number of basins is increased beyond seven, there is only a marginal increase in the yield. This results is in accordance with that reported by Fernandez and Chargoy [1].
