Abstract
A mathematical model has been constructed to demonstrate the physical principles of coalescence of emulsions in which the light component is a petroleum product. On the basis of this model, the average diameter of emulsified particles at the outlet from the chamber has been determined. The emulsion separation efficiency is shown as a function of the charge material with the coalescing chamber completely filled with the charge. As the charge material the authors used granulated polyethylene, foamed polyurethane, polystyrene, or polypropylene. Of the materials investigated for use as the coalescing charge, the best treating results are given by the foamed polyurethane, which has the largest contact surface with the same granule size (3-6 mm).
