Abstract

In a technique for recovering hydrocarbon values from a heavy hydrocarbon-water mixture, the mixture is first delivered through a sub-assembly to remove solid particulates. Then the mixture is delivered through a series of heat exchanger--kettle arrangements in which the mixture is heated above the boiling point of water. Some of the steam formed is allowed to escape through steam removal devices in the heat exchanger. The inside of the heat exchanger includes a plurality of discrete baffles which are unconnected to the heat exchanger and which can be readily removed therefrom. Heating of the mixture continues in the kettles where the bulk of the water is boiled off the mixture. A heavy hydrocarbon oil is recovered in the liquid outlet from the last kettle. The vapors boiled off are recovered and condensed to recover a light hydrocarbon oil and quite pure water.
