OLEAGINOUS MATERIAL EXTRACTION WITH SEPARATION DEVICE TO RECOVER AND SUPPLEMENT FRESH SOLVENT FLOW
A solvent extraction process may be used to generate a miscella stream. The miscella stream may be processed by a separation device, such as a decanter, to form a light phase stream and a heavy phase stream. In some examples, a portion or all of the light phase recycle stream passes to a solvent purification device, such as a membrane, that separates the feed stream into a purified solvent stream and a concentrated light phase stream. The purified solvent stream may be solvent that is substantially or completely free of oil. The concentrated light phase stream contains a portion of the solvent from the feed stream together with nearly all or all of the oil in the feed stream. The purified solvent stream can then be used to supplement the fresh solvent feed to the extractor.

OLEAGINOUS MATERIAL EXTRACTION USING ALCOHOL SOLVENT
An oil extraction process may be performed on an oleaginous feedstock using an alcohol-based solvent, such as ethanol. In some examples, an extraction process involves conveying a material in countercurrent direction with an alcohol-based solvent to generate an extracted material and a miscella. The miscella stream is cooled (14) to form a first solvent-rich layer phase separated from a first oil-rich layer, which is then separated (18) to form a first separated oil-rich stream (100) and a first separated solvent-rich stream (102). In some examples, the first separated solvent-rich stream is recycled back to the extractor and introduced into the extractor at a location (38) different than a location (30) where fresh solvent is introduced into the extractor. Additionally or alternatively, water (103) may be introduced into the separated first oil-rich stream to form a second solvent-rich layer phase separated from a second oil-rich layer, which is then separated (20) to form a second separated oil-rich stream (104).
A method of separating a shell from a seed may involve introducing a feed stream containing shells of a fruit intermixed with seeds of the fruit into a separation column at a feed stream location. The method may also involve introducing a first volume of a separation liquid into the separation column at a first liquid addition location located below the feed stream location and a second volume of the separation liquid into the separation column at a second liquid addition location located above feed stream location. The separation liquid may flow upwardly in the separation column at a rate effective to cause the seeds of the fruit to flow upwardly with the separation liquid toward a seed outlet of the separation column while the shells of the fruit flow downwardly against the upwardly flowing separation liquid toward a shell outlet of the separation column.

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.
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.

A desolventizer for processing solvent-wet solid material may include a thermal recirculation loop to increase thermal performance. In some examples, the desolventizer includes a housing, an ejector, and a vent. The housing contains a first tray and a second tray vertically elevated above the first tray to define a processing space. The ejector has an inlet located between the first tray and the second tray and an outlet also located between the first tray and the second tray. The vent has an inlet located between the first tray and the second tray. In operation, the ejector can draw gas from the processing space via the inlet and discharge the gas through the outlet back into the processing space, creating a recirculation loop.

A soy protein concentrate production process may involve performing multiple liquid extraction steps on a soy feedstock. The soy may be subject to a hexane extraction step to produce a first miscella stream and a solvent-wet soy meal stream. The solvent-wet soy meal stream may be desolventized and then subject to a second hydrous ethanol extraction step to produce a second miscella stream and a solvent-wet soy protein concentrate steam. To purify and recover the second miscella stream, the stream may be chilled to flocculate solid impurities and then passed through a mechanical separation device, such as a centrifuge. In some configurations, the resulting solid impurities from the mechanical separation process are recycled to a desolventization press that desolventizes the solvent-wet soy meal stream from the ethanol extraction step before subsequent thermal desolventization.
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.

Extractor with settling zone near solvent discharge
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.
An extraction system may include a primary extractor that is configured to process a main feedstock undergoing extraction and a secondary extractor configured to process particulate matter separated from miscella produced on the primary extractor. In some configurations, the secondary extractor is an immersion extractor that has a solvent stream flowing in a counter current direction to a direction which the particulate matter flows through the extractor. In operation, the primary extractor can generate a miscella stream containing solvent and components extracted from the feedstock being processed by the extractor. Following separation in which the miscella stream is processed to remove particulate matter, the particulate matter may be charged to the secondary extractor as a feedstock for the secondary extractor. In some examples, the miscella from the primary and secondary extractors are combined and/or the discharged feedstock from the primary and secondary extractors are combined for subsequent processing.
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.
A screen for an extractor system can have a top surface that a solid material contacts during operation of the extractor, a bottom surface opposite the top surface, and a plurality of apertures extending from the top surface through the bottom surface. In one example, the bottom surface of the screen is coated with a non-stick coating while the top surface of the screen is devoid of the non-stick coating.
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.
An asphalt recovery system may include an extractor, a desolventizer, and an evaporator. During operation, the extractor may receive a solvent and roofing waste and extract asphalt from the roofing waste with the solvent. The desolventizer may receive a solvent-wet solids stream from the extractor and vaporize solvent from the solvent-wet solids stream to yield desolventized solids. The evaporator may receive an asphalt-rich solvent stream from the extractor and vaporize solvent from the stream to produce a solvent stream and an asphalt stream. By configuring the evaporator to operate at a pressure above atmospheric pressure, the boiling point in the evaporator may increase as compared to operating the evaporator at a pressure below atmospheric pressure. In turn, this may keep the viscosity of asphalt within the evaporator less than 500 centipoise, which may improve heat transfer to the asphalt and prevent that asphalt from plugging the evaporator.

An extractor can be used to extract solvent-soluble molecules, such as aqueous or organic-soluble molecules, from solid material feedstock for downstream processing and recovery. In one configuration, the extractor is a percolation extractor having one or more extraction chambers each containing a screen supporting the solid materials as it is conveyed through the chamber, a fluid supply system delivering extraction fluid disposed above the solid material, and a fluid recovery system disposed below the solid materials for receiving the extraction fluid and solvent-soluble molecules contained therein. The extractor further includes a screen washing system disposed under the screen and supported against movement. The screen washing system includes a washing fluid intake and a plurality of outlet nozzles directed upward towards the screen. The screen washing system can keep the screen from plugging during operation, improving the extraction efficiency of the extractor.
