Solvent extraction of hydrocarbons from inorganic materials and solvent recovery from extracted hydrocarbons |
| abstract |
A process for the solvent separation of hydrocarbons from tar sand or contaminated soils comprises extracting the hydrocarbons from the sand or soil in a solvent extraction means to form a hydrocarbon rich solvent solution. The rich solvent is separated from the hydrocarbon in a process that utilizes flashing of the solvent in a heated flashing column at ambient pressure. The hydrocarbon is withdrawn from the bottom of the column and the flashed solvent vapors are strategicly withdrawn and passed into a condensation column from which the condensed solvent may be recycled. The flashing column is divided by a series of horizontal, vertically aligned apertured trays. The solution is introduced into the top of the column and the flashing operation is facilitated by the increase in the surface area of the solution as it flows by gravity from tray to tray. The column is maintained at a temperature, preferably above the boiling temperature of the solvent. The process is particularly adapted to the use of chlorinated hydrocarbon solvents and most particularly to the use of methylene chloride. |
