This paper describes the first portable sea water desalination plant based on molten carbonate fuel cells (MCFC). The portable plant, mounted on a skid or a trailer, can be quickly mobilized to continuously produce 1,000 gallons per hour of fresh / portable water and requires practically very minimal _selftenance. The plant uses natural gas as operating fuel and can provide electricity (300 kW), hot water and steam plusdrinking water.
Applications: Such units can be used in:
1) the case of emergency (e.g.: earthquake orother natural disasters)
2) military applications
3) large hospitals / hotels / buildings which are close to any sea water source.
Why Fuel Cells For Portable Sea Water Desalination Plant?:
* Fuel Cells are electrochemical devices and are not limited by the Carnot heat Cycle.
* Overall Efficiency 80 - 90% [Higher Electrical Efficiency + Heat Recovery].
* Environmentally attractive:
A) Sufficiently pollution free: Very low level of emissions
B) Quite & Smooth Operation: Operation of the fuel cells requires a minimum of rotating machinery in the form of pumps & motors, so little noise or vibration.
* Practically No or Minimal _selftenance is required.
