Exergy and Economic Analysis of Hybrid Mechanical Vapor Compression and Membrane Distillation
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Hybridization of two or more desalination processes has been identified as an attractive option for improved energy efficiency and recovery rate. To appropriately assess the performance enhancement of hybrid desalination systems, an integrated approach for energy, exergy, economic, and environmental investigations should be adopted. This study

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling
