Abstract: A method of feeding a contaminated soil to a remediation apparatus to generate a clean soil and mixing the contaminated soil with an aqueous cleaning solution to generate a soil solution. The method also includes subjecting the soil solution to vortical flow in a first direction and subjecting the soil solution to vortical flow in a second direction in an opposite lateral direction from the first direction. The clean soil can then be separated from a dirty aqueous solution. A remediation apparatus used to clean the contaminated soil that includes a chamber having a soil inlet for receiving a contaminated soil and a soil outlet. The chamber is angled downward from the soil inlet to the soil outlet to facilitate the flow of the soil solution through the chamber.

Abstract: A multiple-fluid, multiple-substance, multiple-phase, multiple-pressure, multiple-temperature, multiple-stage turbine engine. In preferred embodiments, one or more fluids are supplied by passageways in the turbine shaft or supplied by non-shaft passageways, or both, through rotor passageways to multiple-phase, multiple-fluid, multiple-substance nozzles affixed to one or more perimeters, radial surfaces, axial surfaces, and/or curved or slanted surfaces of the turbine rotor assemblies. The multiple perimeters, radial surfaces, axial surfaces, and/or curved or slanted surfaces of the turbine rotor assemblies are preferably configured and located for multiple inlet and exit velocities of the nozzles, multiple inlet and exit pressures of the nozzles, or combinations thereof. The one or more fluids entering the turbine may each be a substance of single phase, or a substance of multiple phases, or a mix of the single-phase and/or multiple-phase conditions for two or more entrance fluids.
