Mechanical issues (causing excessive aeration of the fluid) 5. foam is a small bubbles of gas surrounded with a thin film of oil, this phenomena reduces the separation efficiency, foam exists in the gas oil interface when separator pressure decreases, or because of the surface tension, viscosity, and some impurities, because of that, small droplets are generated, these droplets are covered with oil… The most common include: 1.
