Cogeneration of electricity and freshwater by integrating photovoltaic/thermal collectors desalination systems is one the most promising methods to tackle challenges water energy shortages in remote areas. This study investigates a decentralized water/electricity cogeneration system combining concentrated vacuum multi-effect membrane distillation system. The merits such configuration include hi...

A new approach for energy-saving process intensification was demonstrated by a heat integration method taking for instance the C-5 splitter distillation plant existing for extracting pure c-pentane from a petroleum hydrocarbon mixture obtained by naphtha cracking. A process simulation analysis was made without loosening the specifications of separation of the existing plant. A new process-inten...

This report presents a novel Advanced Multi-Effect Distillation (AMED) method that can enable the production of substantial quantities of low-cost desalinated water using waste heat from high temperature reactors (HTRs). Conventional MED systems can currently compete with reverse osmosis desalination in areas where energy costs are relatively low, such as the Middle East. Because AMED can perfo...

We investigate the formation of discrete breathers (DBs) and the dynamics of the mixture of two-species Bose-Einstein condensates (BECs) in open boundary optical lattices using the discrete nonlinear Schrödinger equations. The results show that the coupling of intra- and interspecies interaction can lead to the existence of pure single-species DBs and symbiotic DBs (i.e., two-species DBs). Furt...

The design and optimization of a coupled multicomponent distillation system is a non-linear and multivariable problem. The complexity of this kind of problem results in high solving difficulty. This paper addresses the application of genetic algorithms to the optimization of intensified distillation systems for quaternary distillations. We used a multiobjective genetic algorithm with restrictio...

The economics membrane distillation (MD) and common seawater desalination methods including multi effect distillation (MED), multistage flash (MSF) and reverse osmosis (RO) are compared. MD also has the opportunity to enhance RO recovery, demonstrated experimentally on RO concentrate from groundwater. MD concentrated RO brine to 361,000 mg/L total dissolved solids, an order of magnitude more sa...

Process intensification refers to technologies and strategies that enable simpler and more efficient processes compared to conventional processes. Some features of such intensified processes are less recycle streams, reduced need for waste handling and lower investment and operating costs compared to conventional processes. One way of doing this is by making two or more process steps simultaneo...
