MULTI-STAGE DESOLVENTIZATION OF OLEAGINOUS MATERIAL EXTRACTED WITH ALCOHOL SOLVENT
Systems and techniques can be used to extract solid material with an alcohol-based solvent. To subsequently recover the solvent after extraction, the solvent-wet solid material having undergone extraction can be desolventized. The solvent-wet solid material may be desolventized in multiple stages, either in a single vessel or in multiple different vessels, to generate multiple corresponding condensate streams containing alcohol and water vaporized from the solvent-wet solid material. By splitting desolventization into multiple stages, the composition of the condensate streams generated during desolventization can be individually controlled to benefit downstream processing. For example, the first condensate stream produced during desolventization may have a comparatively low amount of water whereas a second condensate stream produced during desolventization may have a comparatively high amount of water. The first condensate stream may be recycled back to the extractor without further water removal whereas the second condensate stream may undergo additional processing to remove water.

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 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 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 technique for purifying solid materials containing contaminants, such as petroleum coke, may involve introducing the contaminated solid material into an extractor vessel along with an organic solvent. The contaminated solid material and organic solvent may be conveyed in a countercurrent direction during which the contaminant is extracted at least partially out of the solid material and into the solvent. After extraction, the resulting extracted solid material can be processed in a desolventizing unit and the recovered solvent sent back to the extractor. Further, the solvent containing extracted contaminant can be processed in a solvent recovery unit, further recovering solvent that can be sent back to the extractor.
To extract oil from oil seeds in a mechanical pressing operation, the oil seeds may be conditioned and then cooked before being subsequently pressed to release the oil contained in the seeds. In one application, a conditioning vessel is used that includes a shell through which the oil seeds move during operation and multiple heat transfer stages. Downstream of the conditioning vessel, a cooking vessel receives the oil seeds pre-conditioned in the conditioning vessel and cooks the oil seeds, generating a gas-containing stream that includes water vapor. The gas-containing stream is recycled back to one or more of the heat transfer stages of the conditioning vessel, providing direct heat transfer from the cooking vessel to the conditioning vessel. This arrangement can increase the energy efficiency of the operation and improve the performance of the system.
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.
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 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, 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 increase contact between the solids material and surrounding solvent to improve extraction efficiency, the extractor may include mixing hardware that is configured to intermix the solids material with the solvent as solids material drops from the vertically elevated bed deck to the lower bed deck.

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 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.
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.
A thermally conditionable rotary valve is provided. The valve is generally characterized by a valve housing and a valve rotor. The valve housing is configured to operatively retain the valve rotor. Material is passable from a valve housing ingress to a valve housing egress via operation of (i.e., passage by/through) the valve rotor.

The valve rotor is rotatable within the valve housing in furtherance of passing material from the housing ingress to the housing egress.
A pelleting roller assembly includes a hub and shell which form a tapered-bore joint that holes the hub and shell together. Connector holes and at least one jacking hole are formed at the taper joint. Cap screws threaded into the connector holes are used to push the hub and shell into engagement. A disassembly cap screw threaded into the jacking hole is used to pull the hub and shell out of engagement.
An installation removes a portion of the water from a liquid aqueous solution. The installation includes a tank for accumulating liquid aqueous solution therein at a tank pressure. A pump receives liquid aqueous solution from the tank at a pump input and providing the liquid aqueous solution at a pump output with a selected pump pressure higher than the tank pressure. A heater receives liquid aqueous solution from the pump and heats liquid aqueous solution passing though the heater to a selected exit temperature at an outlet of the heater. The liquid aqueous solution exits the heater with an exit pressure between the pump and tank pressures. A first nozzle within the tank receives the heated liquid aqueous solution from the heater and discharges the solution into the tank. The nozzle has a pressure drop for the liquid aqueous solution substantially equal to the difference of the exit pressure and the tank pressure. The pump and the nozzle cooperate to set the outlet pressure at a level exceeding the vaporization pressure of water at the selected exit temperature.

Disclosed is an apparatus and method for conditioning mash product in a conditioning vessel (18) by mixing steam and water together using an injector housing (12) located above the conditioning vessel. The steam-water mixture is added to a mash product within the conditioning vessel (18) so that the mash product is brought to an optimal temperature and moisture content for making pellets from the mash. Steam is supplied to the injector housing (12) and water is mixed with the steam by a spray nozzle (42) located inside the injector housing. The water can be preheated by the steam outside the injector housing prior to mixing with the steam. The amount of steam supplied and the amount of water preheating can be regulated as a function of weather conditions and the starting temperature and moisture content of the mash.
A process for preparing a starch-containing biomass particle stream having a significant percentage of fiber for processing into ethanol comprises the first step of: mixing the particle stream with a liquid solvent to dissolve at least a portion of the starch in the carbohydrate particle stream to form a carbohydrate slurry stream containing starch dissolved in the liquid solvent. This first step removes a portion of the fiber from the carbohydrate slurry stream. In a second step, the carbohydrate slurry stream is held in a settling tank to remove a further portion of the fiber. An enhancement to the process is suitable for use with shell corn or other biomass having an oil-containing germ portion and a non-germ portion comprising mainly carbohydrates and fiber. This enhancement includes the step of grinding the corn to particles of a size suitable for separating the germ particles from the non-germ particles. The germ particles are processed first to remove the oil and then to remove the carbohydrates.
