Liquid-to-liquid oil absorption system and method

A system for removing dissolved and undissolved oil from contaminated water which recycles and reclaims absorbing fluid. An absorbing fluid (CCl2FCClF2) is used in a wet-spiral mixer-absorber-contactor to absorb oil contaminants in produced-water. A downflow spreader system in a processing separator separates the heavier oil absorbing fluid from the oil-decontaminated water. Unspent absorbing fluid is recycled to the absorber-contactor and the decontaminated water is released into the surrounding environment. Spent absorbing fluid is reclaimed in a distillation treatment unit where the oil is used as fuel oil or stored. The absorbing fluid's vapors are drawn off under vacuum from the distillation unit by a jet eductor pump, mixed and condensed with the decontaminated water which drives the jet pump, and then redirected into the system for reuse.
