Single Stage Flash Desalination HW Problem

1. Your assignment is to calculate the concentration of Na+ and Cl- and the TDS of the brine if the feed flow rate is 11.54 kg/h at 90 C, 1 bar, 42000 ppm salt, while the brine is at 40 C and the distillate is 1 kg/h in a single-stage flash desalination unit.

2. You need to use DWSIM and model the feed water as H2O and NaCL with NaCL concentration of 42000 ppm.

3. Neglect NaCL(s) from your reactions.

4. Use the electrolyte template for the solution.

Note: DWSIM is available on the Appstore, on Windows, and MacOS.
