Abstract: An experiment setup was built to test the droplet separation performance of demister. Different experiments were conducted using various Polytetrafluoroethene (PTFE) meshes. Results show that the separation efficiency of demister is dependent on screen thickness, mesh count. Pressure drop increases with the increase of steam flow rate and screen thickness.

Abstract: In this paper, the liquid distributor performance for the falling film evaporation process was tested, and the relationship between the liquid height and flow rate were studied in the experiment. The results showed that the liquid height of liquid distributor is proportional to flow, liquid distributing hole diameter and flow, but inversely proportional to liquid distribution aperture. Overflow may be present at a high flow.

Abstract: This paper presents the thermal performance of a multi-effect distillation (MED) solar desalination unit located in southern China. The system was designed and installed in April 2011, and has been in operation since that time till now. The seawater desalination system is driven by 60 m² all-glass vacuum tubes solar collector with an additional rainwater utilization system to produce fresh water on both sunny and rainy days. The preliminary experimental results show that the water production of the system for per unit of solar collector area could reach up to more than 12.5kg/m²·day under the fine weather conditions. Water production of the system was stable in long period and the annual production could reach to 387.5 m³ in southern China. The economic performance of the system is also discussed. The cost of water production is estimated approximately 4.15 $/m³ for the 15-year service life.
