Abstract
Abstract The essential elements of the electrical system of a treater, or dehydrator, of produced oil well fluids are connected and physically oriented as mounted within the shell of the treater. The flow of the fluids is indicated in relation to the elements for coalescence of the water droplets to cause their subsequent gravitation and collection into a body of water below the electrodes. The electrodes are disclosed in planar form and shown as energized periodically by voltage to generate electrostatic fields in which the water droplets coalesce.
