A novel hybrid adsorption heat transformer – multi-effect distillation (AHT-MED) system for improved performance and waste heat upgrade

Multi-effect distillation (MED) systems are considered to be the most energy-efficient thermal desalination methods. This paper introduces development of a novel system for performance superior MED same operating temperature limits. Such an unprecedented achievement was attained by upgrading heat source using chemical potential adsorption phenomena. The proposed Adsorption Heat Transformer (AHT) cycle hybridized with (AHT-MED) exhibits higher ratio and water production rate than conventional heating sink. generated is supplied first effect system, thus, extending difference between Top Brine Temperature (TBT) Bottom (BBT). offers more number effects, equivalent effects (ΔTe) as design parameter. Using low-temperature (as low 58 °C), can employ increased high 11) due supply at around 80 °C. achieves (approximately 5.4) (2 kg/s) compared standalone (PR: 4.2, WPR: 1 hybrid 10 constant interstage systems. AHT-MED opens up new possibilities source-driven significantly improved performance.
