Methods for recovering a polar solvent from a fluid stream contaminated with at least one polar impurity

Patent Ginosar, Daniel M.; Wendt, Daniel S.

A method of removing a polar solvent from a fluid volume contaminated with at least one polar impurity, such as a free fatty acid, is provided. The method comprises providing a fluid volume that includes at least one polar impurity dissolved in at least one solvent. The fluid volume is contacted with an expanding gas to remove the at least one solvent. The expanding gas may be dissolved into the at least one solvent in the fluid volume to form a gas-expanded solvent. The immiscibility of the polar impurities in the gas-expanded solvent enables separation of the polar impurities frommore » « less

Method of separating and recovering uranium from aluminum-clad metallic nuclear fuel

Patent Herrmann, Steven; Norbash, Kevin

According to one aspect of the invention, a method for separating and recovering uranium from a nuclear fuel element. The method includes immersing a nuclear fuel element containing nuclear fuel and cladding in a molten metal. The nuclear fuel includes uranium. The cladding is selectively dissolved from the nuclear fuel element when immersed in the molten metal. The nuclear fuel is separated from the cladding. The method then includes loading the nuclear fuel into a permeable basket that is electrically configured as an anode of an electrolytic cell. There are also a molten salt electrolyte and a cathode in themore » « less

Method for removing contaminants from plastic resin

Patent Bohnert, George W [Harrisonville, MO]; Hand, Thomas E [Lee's Summit, MO]; DeLaurentiis, Gary M [Jamestown, CA]

A resin recycling method that produces essentially contaminant-free synthetic resin material in an environmentally safe and economical manner. The method includes receiving the resin in container form. The containers are then ground into resin particles. The particles are exposed to a solvent, the solvent contacting the resin particles and substantially removing contaminants on the resin particles. After separating the particles and the resin, a solvent removing agent is used to remove any residual solvent remaining on the resin particles after separation.

Method of removing contaminants from plastic resins

Patent Bohnert, George W [Harrisonville, MO]; Hand, Thomas E [Lee's Summit, MO]; DeLaurentiis, Gary M [Jamestown, CA]

A method for removing contaminants from synthetic resin material containers using a first organic solvent system and a second carbon dioxide system. The organic solvent is utilized for removing the contaminants from the synthetic resin material and the carbon dioxide is used to separate any residual organic solvent from the synthetic resin material.
