A system, process and method for remediating contaminated soil and solvent recovery. A solvent mixture including a polar and a non-polar solvent is mixed with contaminated soil in mixing vessels, allowing the solvent mixture to extract contaminates from the soil. The solvent mixture is separated from the soil using bicanting units to form a solvent stream and a soil stream. The soil stream goes through air sparging in a dryer to remove residual solvent vapor. Water and/or micro-fines are extracted from the solvent stream using a centrifuge. The solvent stream undergoes distillation in a distillation unit to remove the containments from the solvent stream, while recovering separately the solvent mixture and a product. The recovered solvent mixture can be recycled back to the mixing vessels. The contaminates can be BTEX or F1-F4 hydrocarbons, and the product can be oil or other hydrocarbons. The system can be mobile.
