Abstract
A coalescer is provided which separates dispersed liquid hydrocarbon phases from continuous liquid aqueous phases by increasing the size of the dispersed phase droplets using a variety of coalescing media, preferably in granular form. The coalescer must contain at least three sides; however any number of sides up to a circle can be used, and a circular cross-section is preferred. Untreated aqueous phase is drawn through the coalescer media, where the dispersed droplets increase in size. The dispersed droplets are coalesced to a sufficiently large degree to rise to the top of the coalescer against the downward flow of the continuous phase, said continuous phase being withdrawn from the bottom portion of the coalescer and the separated, previously dispersed phase withdrawn from the top of the coalescer.
