  • Patent number: 4111805
    Abstract: A method and apparatus for separating solvent from liquid sulfur. The invention entails introducing an emulsion of liquid sulfur and a solvent of lower specific gravity into a first zone of a separator segregating the emulsion behind a sloped baffle to allow breaking of the emulsion with the solvent rising above the sulfur to form a separate layer of liquid; restraining the liquid sulfur behind a second baffle having sufficient clearance from the floor of the vessel to allow sulfur to flow thereunder while forming a second zone of liquid behind this baffle in which a collecting chamber is arranged so that solvent flows from a separated upper layer of liquid over a trapout weir into the chamber to be removed; and downstream of the second baffle a restraining weir of sufficient height to maintain an operating level in the second zone allowing the overflow of solvent into the collecting chamber with liquid sulfur overflowing the restraining weir into a collection means.
