  • Solvent removal and recovery from inorganic and organic solutions
    Patent number: 8852436
    Abstract: A process for recovering solvents from inorganic and organic solutions is disclosed. The process utilizes a polymer capable of selectively extracting the solvent from the inorganic or organic solution. Introduction of the polymer into the solvent solution creates formation of a polymer-rich phase and a solute-rich phase. The recovered solvent may be separated from the polymer-rich phase by heating the polymer-rich phase to at least the cloud point of the polymer. The polymer and/or solute may be recycled for further use in the solvent recovery process.
    Type: Grant
