ABSTRACT:
A water degreaser system which recycles and reclaims absorbing fluid. Freon absorbing fluid is used in a wet spiral absorber-contactor to absorb oil contaminants in produced-water. A downflow spreader system in a processing separator separates the heavier freon from the decontaminated water. Unspent freon is recycled to the absorber-contactor and the clean water is released into the surrounding environment. Spent freon is reclaimed in a distillation treatment unit where the oil is drained off and stored. The freon vapors are drawn off under vacuum from the distillation unit by a jet pump, mixed and condensed with the decontaminated water which drives the jet pump, and then redirected into the system for reuse.
