  • Patent number: 5238578
    Abstract: An apparatus and method for processing an influent liquid including at least a solvent and non-volatile impurities by combining the liquid with a vapor to produce a precipitated sludge is disclosed. The influent liquid is introduced into a wet well. A saturated, water containing reflux and a precipitated sludge are transferred to the well from a reactor. The saturated, water containing reflux precipitated sludge and influent liquid are mixed to form a mixture of saturated, water containing reflux and precipitated sludge. The saturated, water containing reflux is then transferred to the reactor and contacted with a vapor to form the precipitated sludge. The vapor is then discharged from the reactor, and the precipitated sludge is discharged from the wet well.
