► The new HTGR + MED coupling scheme was proposed. ► KAIST coupling scheme uses PCHE without any intermediate loop. ► KAIST coupling scheme has independent structure between MED and heat sink. ► Water production capacity increases by 258% compared to previous researcher's results. ► Water cost is reduced by 9.0% compared to previous researcher's results. a b s t r a c t a r t i c l e i n f o Th...

Seawater desalination plants have been utilized to supply fresh water to the State of Kuwait since the early 50’s. In spite of the fact that there are several types of desalination technology that can be used more efficiently and economically, one type of desalination technology, namely multi-stage flash (MSF), has been used extensively in Kuwait. This work is an attempt to identify the most su...

Countries which do not have adequate supply of freshwater sources like Kuwait resort to using desalination plants to meet their demand. Kuwait had used Multi-flash desalination (MSF) plants sine the 50’s of the last century to satisfy its ever increasing demand. Many new and more efficient and cost effective desalination technologies are currently available. Kuwait is in the process of building...

Feasibility study on nuclear seawater desalination plant in which a 200 MW nuclear heating reactor (NHR-200) couples with MED processes has being finished at Institute of Nuclear Energy Technology (INET) of Tsinghua university in China, the Chinese government has agreed to built the kind of nuclear seawater desalination plant in Shandong peninsula of China. Two different kinds of MED processes,...

A novel cogeneration system is proposed for power generation and seawater desalination. It combines the CRGT (chemically recuperated gas turbine) with the MED-TVC (multi-effect thermal vapor compression desalination) system. The CRGT contains a MSR (methane-steam reformer). The produced syngas includes plenty of steam and hydrogen, so theworkingmedium flow increases and NOx emissions can achiev...

At low pressure and temperature, water is easily vaporized under partial vacuum pressure. Desalination of seawater as source of potable water is globally considered as an applied reliable technology. At low temperature and pressure, the heat transfer process yield is higher than any normal process. Therefore, the rate of vaporization of seawater is much higher than any usual processes. The part...

Multiple Effect Distillation (MED) is generally considered to be the desalination technology most suited to integration with concentrating solar thermal collectors on a medium to large scale. However the cost and energy requirement of Reverse Osmosis (RO) have fallen significantly in recent years, so that solar thermal powered RO deserves consideration. We compare commercial desalination proces...

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...
