摘要： A liquid extractor may include an extraction chamber containing a bed deck configured to support a solid material as the solid material is conveyed through the extraction chamber. To introduce solvent into the solid material being processed, the extractor may include a solvent injection orifice extending through the bed deck and a solvent injector. The solvent injector can receive solvent from a source and cause the solvent to rotate within the solvent injector before discharging the solvent through an outlet in fluid communication with the solvent injection orifice. The rotational flow motion imparted by the injector can create a vortex that functions to scout out any particles that may be present in the injector.

摘要： An improved biodiesel production process includes the steps of processing a feedstock to produce biodiesel, cooling the biodiesel so as to form sediment, and filtering the biodiesel to remove the sediment. The resulting biodiesel from the cold filtration process avoids problems of sediment formation during storage and transportation.

摘要： An immersion extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, a final bed deck extends from below a solvent level maintained in the housing to above the solvent level such that solids material is conveyed out of the solvent pool and toward a feed outlet at the end of extraction. The bed deck may include a drainage section positioned between the top of the solvent level in the extractor and the feed outlet, allowing solvent to drain out of the solids material before being discharged through the feed outlet, thereby increasing the efficiency of the extraction process.

摘要： A bearing assembly can be used in liquid service applications where the bearing assembly is intermittently or continuously exposed to liquid, such as below the liquid level of a solid-liquid extractor. In some examples, the bearing assembly includes an annular sleeve and an annular bearing. The annular sleeve is designed to be installed over the end of a rotatable shaft and positioned inside of a housing through which the rotatable shaft at least partially protrudes. The annular sleeve has an outer surface and length parallel to the rotational axis of the rotatable shaft. The outer surface of the annular sleeve may taper radially inwardly along at least a portion of the length of the sleeve. As a result, the bearing assembly and rotatable shaft positioned therein may pivot within housing about the taper of the annular sleeve.

摘要： A process extracts and reclaims the components of an asphalt-based material having as constituents at least asphalt and one or more solid materials. A solvent for asphalt dissolves the asphalt constituent to form a slurry of asphalt-solvent liquid and the solid materials. The liquid and the solids in the slurry are then separated. The liquid is separated into solvent and asphalt. The solids, when of more than one type, are separated into at least one pure constituent solid. In a preferred embodiment, the process runs in a continuous mode with the various materials flowing as streams into spaces where steps of the process operate. The process can be used for both worn roofing shingles and for asphalt paving.

摘要： A desolventizing system for removing solvent from a quantity of solvent-laden particles such as flakes comprises first and second desolventizer units, each having an inlet port for receiving solvent-laden particles, an outlet port for discharging at least partially desolventized particles, and a solvent vapor port. A solvent trap is connected between the outlet port of the first desolventizer through a first airlock, and to the inlet port of the second desolventizer unit. Particles entering the solvent trap through the first airlock are conveyed to the inlet port of the second desolventizer. The second desolventizer unit has an airlock connected to the outlet port of the second desolventizer unit. The solvent trap has a vent preferably in the upper part of the trap for connection to a vacuum source that maintains a partial vacuum within both the solvent trap and the second desolventizer unit allowing liquid solvent and water permeating particles within the second desolventizer unit to vaporize efficiently at a relatively low temperature. Solvent vaporized in each desolventizer unit can be drawn out through the solvent vapor port of the desolventizer unit for further processing and later reuse.

摘要： A fractionation column can be used to separate a liquid containing multiple components into its constituent components based on vapor pressure. While the fractionation column may be designed for certain operational performance, the operational characteristics may change, for example, due to changed flow rates through the column and/or fouling in the column. In some examples, a fractionation column is described that includes a fractionation tray formed of multiple tray decks that move relative to each other. The tray decks can have apertures that move relative to each other between a position in which there is a comparatively large amount of open area through the fractionation tray to a position in which there is a comparatively small amount of open area through the fractionation tray. Movement of the trays can control turndown and/or clear fouling buildup on the tray surface.

摘要： An extractor may have a housing that maintains a solvent pool in which solids material being processed is immersed during operation. One or more bed decks can be positioned inside of the housing to provide multiple extraction stages. In some examples, the bed decks are arranged to provide one bed deck positioned at a vertically elevated position relative to another bed deck, thereby providing a drop zone where the solids material passing through the machine drops from the vertically elevated bed deck to a lower bed deck. To reduce the amount of solids material passing through the drop zone that becomes entrained in the solvent, the exactor can be configured with a settling zone. In some examples, the settling zone is formed by truncating the length of the vertically elevated bed deck, providing increased space and residence time for the solids material to fall out of suspension.

摘要： A vertical seed conditioner may be formed of a plurality of sections that can be individually removed for repair and/or replacement without requiring the entire seed conditioner be permanently decommissioned. For example, the seed conditioner may be formed of a plurality of heat transfer sections stacked vertically with respect to each other to form the conditioning vessel. Each heat transfer section may include an inlet manifold, an outlet manifold, and multiple heat transfer tubes extending from the inlet manifold to the outlet manifold. The multiple heat transfer tubes may be spaced from each other to provide a gap between adjacent tubes through which the granular solid can travel.
