Abstract:
Solvent blend processes and products. A solvent blend particularly adapted for use in a solvent extraction process for decontaminating drill cutting waste containing drilling fluid base oil, or soil containing hydrocarbon liquids within the soil matrix is described where the solvent blend is recovered from, and contains extracted contaminants from, a solvent extraction and solvent and solute recovery process, and the solvent blend, when re-used in a solvent extraction process, demonstrates improved selectivity for dissolving solutes as compared to a non-contaminant containing solvent. The recovered, decontaminated solids are also described.

Claim (Index 1):
A solvent blend particularly adapted for use in removing hydrocarbon contamination from soil matrices or drilling wastes,\n wherein, the solvent blend is used to wash a hydrocarbon containing soil matrix or drilling waste, the solvent blend being comprised of a first solvent which is soluble in the hydrocarbon contamination, and at least one secondary solvent which is more soluble in the hydrocarbon contamination, the said secondary solvent, or group of secondary solvents, being substantially comprised of hydrocarbon molecules which were extracted from the hydrocarbon contamination of the soil matrix or drilling waste, the solvent blend demonstrating an improved selectivity and/or solute solubility, of the hydrocarbon contamination in the soil matrix or drilling waste, when compared to the first solvent alone.
