ABSTRACT:
A system for removing dissolved and undissolved oil from contaminated water which recycles and reclaims absorbing fluid. An absorbing fluid (CCl.sub.2 FCClF.sub.2) 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 jet eductor pump, mixed and condensed with the decontaminated water which drives the jet pump, and then redirected into the system for reuse.
