Abstract
1364942 Treating oil-containing sludges TEXACO DEVELOPMENT CORP 8 Jan 1972 952/72 Heading C1C [Also in Division C5] A process for treating an aqueous oil-containing sludge comprises mixing the sludge with at least one hydrocarbon having at least 4 C atoms per molecule (e.g. butane, pentane) and a specific gravity lower than the sludge, settling the mixture, separating the mixture into water having a reduced C.O.D. with respect to the sludge, a solids-water phase and an oil-hydrocarbon phase, heating the oil-hydrocarbon phase above the critical temperature of the hydrocarbon(s) to 275‹ to 420‹ F. under 500- 600 p.s.i.g. and thereafter separating the hydrocarbon portion from the oil portion. In the Figure, sludge and hydrocarbon is mixed at 1 and settled in drum 5. An oil-hydrocarbon phase is removed through line 6 to heater 9 and the hot mixture is passed to fractionating tower 11, the oil being removed through line 15 and the hydrocarbon being removed through line 3 and after cooling and depressurizing being mixed with more sludge. A water phase is removed from drum 5 through line 19 and it may be biologically treated. A solids-water slurry is removed from drum 5 through line 17 and it may be steamed.
