Abstract

A composition and method for displacing, dissolving, extracting, recovering, and/or removing solvent and/or any solvent-associated liquids from a solvent-treated material or penetrating through pores or the surface of a solvent-treated material using a solvent-extracting composition for contacting solvent-treated material and separating the solvent and any solvent-associated liquids from the solvent-treated material as well as the solvent-extracting composition.

Claims (42)

1. A method for removing a turpentine liquid and solvent-associated liquids trapped within pores of a material, the material having entrapped a hydrocarbon-containing material having API gravity of more than 10° has been treated with turpentine liquid, comprising the steps of:

a) providing a solvent-extracting composition,

b) contacting said material having entrapped a hydrocarbon-containing material having API gravity of more than 10° that has been treated with turpentine liquid with said solvent-extracting composition such that said solvent-extracting composition penetrates into pores of the material,

c) forming a recovery mixture, wherein the recovery mixture comprises at least a portion of the turpentine liquid and solvent-associated liquids extracted into the solvent-extracting composition; and

d) separating the recovery mixture from any residual material containing non-extracted material from the material having API gravity of more than 10° that has been treated with said turpentine liquid that is not extracted into the solvent-extracting composition.

2. The method of claim 1 , further comprising the step of:

separating the recovery mixture into a first portion and a second portion, the first portion comprising a turpentine liquid product stream that includes at least a portion of the turpentine liquid and any solvent-associated liquids extracted from the pores of the material, the second portion comprising at least a portion of the solvent-extracting composition.

7. The method of claim 6 , wherein said turpentine liquid comprises alpha-terpineol, alpha-pinene, beta-pinene, p-cymene, or a combination thereof.

8. The method of claim 1 , wherein said solvent-extracting composition comprises an alcohol.

9. The method of claim 1 , wherein said solvent-extracting composition comprises one or more acyclic or cyclic alcohols.

10. The method of claim 1 , wherein said solvent-extracting composition comprises methanol, ethanol, propanol, isopropanol, butanol, isobutanol, pentanol, 1-Pentanol, 3-Methyl-1-butanol, 2-Methyl-1-butanol, 2,2-Dimethyl-1-propanol, 3-Pentanol, 2-Pentanol, 3-Methyl-2-butanol, 2-Methyl-2-butanol, hexanol, 1-Hexanol, 2-Hexanol, 3-Hexanol, 2-Methyl-1-pentanol, 3-Methyl-1-pentanol, 4-Methyl-1-pentanol, 2-Methyl-2-pentanol, 3-Methyl-2-pentanol, 4-Methyl-2-pentanol, 2-Methyl-3-pentanol, Tertiary 3-Methyl-3-pentanol, Primary 2,2-Dimethyl-1-butanol, 2,3-Dimethyl-1-butanol, 3,3-Dimethyl-1-butanol, 2,3-Dimethyl-2-butanol, 3,3-Dimethyl-2-butanol, 2-Ethyl-1-butanol, benzene, toluene, methyl ethyl ketone (MEK), furfural, tetrahydrofuran (THF), acetone, hydrofluoric acid, hexane, xylene, or a mixture thereof.
