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.
