Making potable water through desalination plants is a very important process in Iran where clean water is highly required. On the other hand, large amount of fossil fuel sources leads to the development of gas turbine power plants all over the country. Furthermore, Persian Gulf in the south and Caspian Sea in the north could be the main sources for supplying potable water in water scarcity area...

Fuel allocation in a combined steam-injected gas turbine (STIG) power generation and multi-effect thermal vapor compression (METVC) desalination system is studied, using seven methods: (1) Products Energy Method, (2) Products Exergy Method, (3) Power-Generation-Favored Method, (4) Heat-Production-Favored Method, (5) Basic Exergetic Cost Theory, (6) Functional Approach and (7) Splitting Factor M...

Solar stills are very simple to construct and to operate but their efficiency and productivity are fairly low. To increase the yield from stills different methods were adopted. In this paper, an experimental investigation on single and double effect desalination systems are reported and effects of some parameters such as water depth, input radiation intensity and salinity on the productivity of...

The paper presents an attempt to assess sustainability of desalination plants for water production based on resource, environmental and economic indicators. Four types of desalination plants are taken into a consideration: single MSF, dual purpose MSF, RO with local energy consumption and RO with PV electric energy production. The analysis is based on data from desalination plants in Gulf count...

Clean water obtained by desalinating sea water or by purifying wastewater, constitutes a major technological objective in the so-called water century. In this work, a high-performance reverse osmosis (RO) composite thin membrane using multi-walled carbon nanotubes (MWCNT) and aromatic polyamide (PA), was successfully prepared by interfacial polymerization. The effect of MWCNT on the chlorine re...

Humidified gas turbines (HGT) have been identified as a promising way of producing power. The use of the steaminjected gas turbine (STIG) HGT cycle in a combined power and water desalination system was analyzed using energy and exergy performance criteria. A brief description and rationale of the background of HGT cycles and dual-purpose power and water systems is given. A thermal desalination ...

Large-scale desalination plants are complex systems with many inter-disciplinary interactions and different levels of subsystem hierarchy. Advanced complex systems design tools have been shown to have a positive impact on design in aerospace and automotive, but have generally not been used in the design of water systems. This work presents a multi-disciplinary design optimization approach to de...
