Abstract: 10 DEHYDRATED OIL Fig. 1 (54) Title: HIGH FLUX ELECTROSTATIC SEPARATOR FOR SUBSEA APPLICATIONS (57) : An apparatus and method for separat- ing water from an oil-water influx are provided. The apparatus includes a separation vessel (10) having an inlet (15), an oil collection portion (20) at its upper end (25), and a water collection portion (30) at its lower end (35). Multiple high voltage tubes (40), each containing an electrode (45), are located within the oil collection portion (20). These high voltage tubes (40) are staggered in length and held in place by perforated plates (100). The oil- water influx flows through the inlet (15) of the vessel (10) into the high voltage tubes (40), where it is subjected to an electrostatic field. The electrostatic field causes water droplets in the influx to coalesce and foiin a water 85 // out-flux which flows downwardly into the water col- lection portion (30) of the vessel (10). The remaining 80 stream of dehydrated oil flows upwardly to the upper outlet end (25). The oil collection portion of (20) the separation vessel (10) may be oriented vertically or at 30 an angle.
