  • Phase separation by gas evolution
    Patent number: 5360554
    Abstract: A solute can be separated from a solute/solvent solution by dissolving a gas-forming material into said solution and then adjusting the temperature, pressure and solute concentration of the resulting solution such that a Joule-Thompson free expansion of the gas-forming material released from the solution will produce a three-phase separation of the components of said solution.
