a droplet is separated when it reaches ‘the bath’.
This theory is based on the assumption that a droplet falls at a speed Ut under the influence of gravity. The fall time is determined by the fall height, Hsep. (Droplet fall time = Hsep/Ut) The gas velocity is Ug while the horizontal distance that the droplet travels before being absorbed by the surface of the liquid is Lsep. (Droplet retention time is Lsep/Ug.)
Based on this formula, you would have to extract all the droplets from the gas. However, the maximum achievable result is 98% dry gas – or 2% wet gas.
