Abstract:
An apparatus for reclaiming deicer from produced water of an oil well, comprising:a fractionation tower having a top condenser section, a bottom heat exchanger section and an intermediate packing section; at least one condenser positioned in the condenser section, the at least one condenser having an internal conduit through which cooling fluids flow; a deicer outlet positioned in the condenser section, for removal of condensed deicer; at least one inlet in the tower to receive produced water contaminated by deicer, the inlet being coupled to the internal conduit of the at least one condenser such that produced water must pass through the at least one condenser to enter the at least one inlet; a water outlet in the heat exchanger section; means for controlling operation of the water outlet to maintain a predetermined level of accumulated water in the heat exchanger section; a heat exchanger positioned in the heat exchanger section, the heat exchanger having an internal conduit adapted to be coupled with a source of hot fluids produced by an external heat source, the circulation of hot fluids through the heat exchanger heating accumulated water in the heat exchanger section.
