ABSTRACT:
A method for continuously extracting a solute from a carrier medium. A volatile solvent is placed in a lower distillation chamber of a vessel, the vessel including a convergent baffle disposed to separate the vessel into a lower distillation chamber and an upper extraction chamber. The convergent baffle is contoured to converge to define a conduit riser projecting upwardly into the extraction chamber and terminating in a vaporized solvent port placing the distillation chamber in fluid flow communication with the extraction chamber. A carrier medium containing a solute to be extracted is placed in the extraction chamber. The volatile solvent in the distillation chamber is then vaporized. The vaporized solvent flows upwardly and is converged through the convergent baffle and conduit riser. The converged vapor stream passes through the vaporized solvent port into the carrier medium, flowing through the carrier medium and inducing a linear-torroidal flow in the carrier medium. Solute is extracted from the linear-torroidal flowing carrier medium into the converged solvent passing therethrough. The vaporized solvent including extracted solute is then condensed after it exits the carrier medium, and is returned to the distillation chamber of the vessel to continue further extraction.
