Turn-key Forced Evaporation Solutions



 

Forced evaporation makes use of the environmental energy available in the air to evaporate water. This is contrary to thermal evaporation where water is heated with process heat to evaporate the water. Evaporating water at a rate of 1 kg/s requires around 2400 kW of energy.

The environment is a great source of energy, especially in more arid parts of Southern Africa. By atomizing water into small droplets and exposing it to the atmospheric conditions, large quantities can be evaporated at minimal input costs.

The following factors influence the evaporation rate:

  • Droplet size.
  • Droplet hang time (exposure time to air).
  • Ambient conditions:
  1. Wind speed.
  2. Relative humidity.
  3. Temperature.

Key to the success of evaporation is that the exposure time of a droplet is long enough for the droplet to completely evaporate. This is typically why droplets are blown into the air using fans. The droplet size also plays an important role in how long a droplet stays airborne. Large droplets will fall too fast and won’t evaporate.
