In the present article, a thermodynamic analysis is given for the following systems: (i) conventional multi-effect boiling (MEB), (ii) MEB equipped with a mechanical vapor compression facility, (iii) MEB with a thermo-vapor compression device, (iv) combined conventional MEB and vapor-thermo compression systems. The analysis shows that the combination given by item (iv) is more advantageous than the other three alternatives. A case study showed that such combination could increase the productivity twice that of a conventional MEB plant utilizing the same number of effects and with almost the same performance ratio. Moreover, less number of effects work under vacuum conditions which means less leakage troubles and less evacuating motive steam.
