The future of MED technology
R&D efforts towards the increase of MED units capacities have resulted in the key technologies being available for large plant such as 15 MIGD per single unit. The basic design beside shows the outlook off such plant.
In addition MED-TVC allows unparalleled flexibility when combined with power plants thanks to the HYBRID MED concept.This concept provides two types of MED units:
- The MED-TVC2 can be fed with two types of steam pressure depending on the load factor of the power plant. When electrical demand is high a lot of LP steam is available, when it is low the steam extracted from the turbines is a limited quantity of MP steam.
- The MED-MTVC units can be driven by LP steam during high electrical demand, and with electrical power when electrical demand is low. Such unit provides a mechanical vapour compression system to be installed in parallel with the LP thermocompressor.
An HYBRID MED system can use both types of units or one only, in all cases it brings very important savings on the production cost of fresh water
