Abstract
This invention relates to the treatment of droplet dispersions employing a novel device which is a coalescer element consisting of a body of porous material having communicating porosity and two opposite faces, the pore size increasing progressively from a region at or adjacent one face of the body to the opposite face. In the treatment according to the invention the dispersion is passed through the coalescer element in a direction of increasing pore size and the disperse phase is coalesced by the element. The progressive increase in porosity of the novel coalescer is advantageous in that it provides a large target area at the inlet and hence a high collection efficiency for droplets of disperse phase below 100.mu.m in diameter, without the disadvantage of the high resistance to liquid flow normally associated with devices having a high target area.
