Results

By Using RSCC we get the following results:

1. Increase the steam gained from the same amount of seawater enter the
process (from 184000 to 198000)kg/hr around 7.7%, this increase by using
just 4-stages.
3
2. Increasing the plant capacity per day from (2271.25 to 2430) m /day by
about 7.1%.

3. Increasing GOR from 7.8 to 8.4 (efficiency increased).
4. Lower GHG emissions, that’s due to we get more freshwater by using solar
power.
5. More freshwater without thermal or electrical power added.
6. Decrease the cost of distillation, that’s due to decreased operational cost for
the plant.

7. Get freshwater faster than the conventional method.
8. Lower energy consumption.
9. Can be used for any thermal desalination process (MSF, MED, VC).

The performance of the modified (RSCC) MSF plant can be shown by these
