Water enriched with its natural isotopes plays an important role in research and technology. Heavy water (HDO, D2O) is used in nuclear technology and research and the increasing market demand is expected in future if nuclear fusion will be used for energy production. Water enriched in O is used in research and medicine in trace experiments, as is water enriched in O. Recently there appears to b...

Two different alternatives for etherification of glycerol (G) with tert-butyl alcohol (TBA) are developed and analyzed. The conventional reaction separation recycle system uses a plug-flow reactor to perform the reaction in liquid phase, in the presence of a heterogeneous catalyst (Amberlyst 15). The separation of the products from reactants is achieved by two distillation columns where pure gl...

► 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...

The simplest and easily accessible type of solar distillation is passive solar still which utilizes freely and abundantly available sun energy for removal of salinity/impurity from saline/brackish water. The main drawback of passive solar still is its lower efficiency and distillation output. Different designs of passive solar stills are fabricated and tested by various researchers to meet wate...
