Each cell mainly consists in a horizontal tubes bundle. The top of the bundle is sprayed with sea water make-up that flows down from tube to tube by gravity Heating steam is introduced inside the tubes, and as the tubes are cooled externally by make-up flow, steam condensates into distillate (fresh water) inside the tubes. At the same time sea water warms up and partly evaporates by recovering the condensation heat (latent heat). Due to evaporation sea water slightly concentrates when flowing down the bundle and gives brine at the bottom of the cell. The vapour obtained by sea water evaporation is at a lower temperature than heating steam. However it can still be used as a heating medium for the next effect where the process is repeated (see next slide). The decreasing pressure from one cell to the next one allows brine and distillate to be drawn to the next cell where they will flash and release additional amounts of vapour at lower pressure. This additional vapour will condense into distillate in the next cell. Single Cell Arrangement MAY 2009 GENERAL PRESENTATION SLIDE 16 Standard Multiple Cells Arrangement This Scheme represents a Multiple Effect Distillation unit consisting of 3 cells In the last cell the produced steam is condensed on a conventional shell and tubes heat exchanger (distillate condenser) cooled by sea water. At the outlet of the condenser, part of the warmed sea water is used as make-up of the unit, and part rejected to the sea. Brine and distillate are collected from cell to cell till the last one from where they are extracted by centrifugal pumps The thermal efficiency of a unit is quantified by the Gain Output Ratio (GOR) GOR = 3 GOR = MAY 2009 kilos of distillate produced 1 kilo of steam introduced SLIDE 17 GENERAL PRESENTATION Enhanced Process using Thermal Vapour Compressor (MED – TVC) GOR can be enhanced by addition of a thermocompressor (TVC) between one of the cells and the hot one. Using LP or MP steam this static compressor will take part of the vapour raised in one cell and recycle it into higher pressure vapour to be used as heating medium for the first one. GOR = 6 MAY 2009 GENERAL PRESENTATION SLIDE 18 Desalination without available steam using Mechnical Vapour Compressor (MED –MVC) When no steam is available, it is still possible to use the MED process by adding a Mechanical Vapour compressor (MED-MVC). In such case the vapour is recycled from the cold cell to the hot one by means of a centrifugal compressor driven by an electric engine. A maximum capacity of 5,000 m3/day can be obtained with current compressor technology MAY 2009 GENERAL PRESENTATION SLIDE 19 Optimising for Winter and Summer Operations: Hybrid Plants Purpose: decrease overall fuel consumption of the Power Plant / Desalination Plant: Priority for thermal desalination by recovery of the available exhaust steam (MED-TVC) Balance of water production by RO or MED-MVC 100% Water demand 100% RO 50% r we Po RO d w Po d em an Water produced with Steam from Power Generation de m 50% an d er Concrete Example: Combined thermal and membrane technology of Fujairah-2 Project signed in 2007: 100 MIGD MED-TVC + 30 MIGD RO MED-TVC winter summer winter Sidem OTV Note: Veolia Water Solutions & Technologies through Sidem & OTV subsidiaries is the only company able to provide inhouse hybrid plants based on MED & RO technologies MAY 2009 GENERAL PRESENTATION SLIDE 20 Attributes & Benefits of MED Technology ATTRIBUTES No Brine Recycling Pump BENEFITS Electrical Consumption 2 to 3 times less than other thermal desalination processes Less maintenance downtime and no need to shutdown all plant during pump maintenance No sophisticated, expensive and critical rotating pump in place Reduced corrosion and scaling Low Maintenance Cost and High Availability No risk of distillate contamination in case of tube leak No change in the quality of distillate in case of leak Thermocompressor can be added for steam above 2 bars to enhance efficiency Unlike other thermal process which are limited by the Top Brine Temperature (2.7 bars), the design of the MED Unit can take benefit of higher steam pressures (until 40 bars) Seawater treatment at intake is simple and easy to operate No need for expensive, chlorine-sensitive membranes as in other desalination processes Operation at temperatures below 65°C and at low concentration (
