A one-stage separator design by Norway's Aibel Technology and the latest experimental results is discussed. A more efficient separation process is attained by the introduction of an electrostatic coalescer with isolated electrodes in the first-stage separator. The enhancement in separation has made new operational condition possible, including reduction in operational temperature, reduction in retention time, and increase in tolerance to high upstream shear forces. The primary and significant feature of electrostatic coalescers is the effect of the electrostatic field strength on conductive droplets (water) in an insulating media (oil). The internal electrostatic coalescer elements, in the test separator, increases the droplet size and break down the emulsion layer. The test concluded that a proper separation, for both light and heavy oil tests, can take place with or without highly-reduced chemical amounts, which is advantageous from a cost and environmental viewpoint.
