Hi,
Do you think the following desalination system is practical (see the attachment)?
We don't need Md to reach high salinity at output...if we reduce Mf , , and keep Md constant, output salinity will be increased....

I'm not sure what i I answer your question but the technology is very practical and used in many plants around the world.
As for " Mf=24 kg/h, Md=3.8 m3/h??? "
The reason the volume is very large is because the Md stream is a water vapor stream which has a very low density, hence, very large volume.
There are many benefits to such a plant but benefits needs to be compared to the alternative. This alternative is the most common desalination method today: Reverse Osmosis. Reverse Osmosis plant (for seawater desalination) is usually 1/3 the price of a mechanical vapor compression plant and requires 1/3 the power consumption.
But, on the other hand, Mechanical Vapor Compression has many advantages over reverse osmosis, some of which are:
- Very high quality product (distilled water)
- Quick and simple installation of standard, factory assembled and skid-mounted units
- High availability and very high reliability for continuous and safe operation
- Lower operation and maintenance costs (besides the power consumption)
- Longer plant life expectancy
- Minimal requirements for intake and pretreatment systems
- Smaller foot print and lower chemical consumption
Thanks,
I know the benefits of thermal desalination.
I want to know what is the main advantage of water re-circulation?
For more production rate:
If we reduce Mf, and keep Md constant, output salinity will be increased....
