Abstract: The present invention relates to methods and apparatuses for the operation of a distillation tower containing a controlled freezing zone and at least one distillation section. The process and tower design are utilized for the additional recovery of hydrocarbons from an acid gas. In this process, a separation process is utilized in which a multi-component feedstream is introduced into an apparatus that operates under solids forming conditions for at least one of the feedstream components. The freezable component, although typically CO2, H2S, or another acid gas, can be any component that has the potential for forming solids in the separation system. A dividing wall is added to at least a portion of the lower distillation section of the apparatus to effect the separation of at least some fraction of the hydrocarbons in that portion of the tower.

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 The hydrocarbon is withdrawn from the bottom of the column and the flashed solvent vapors are strategicly withdrawn and passed into a condensation column from which the condensed solvent may be recycled.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.
