摘要： A method of absorbing a solvent from a gas stream may involve flowing a gas stream comprising air and a hydrocarbon through an absorption column in a countercurrent direction with a first lean absorbent liquid to absorb solvent out of the gas stream and generate a first conditioned gas stream and a first rich absorbent liquid. The method can then involve flowing the first conditioned gas stream through the absorption column in a co-current direction with a second lean absorbent liquid to absorb solvent out of the first conditioned gas stream and generate a second conditioned gas stream having a reduced concentration of the hydrocarbon than the first conditioned gas stream and a second rich absorbent liquid.

摘要： 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.

摘要： 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.

摘要： 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).

摘要： Devices, systems, and techniques can be provided for processing an oil-containing material with an alcohol-based solvent to extract oil from the material. In some examples, a system includes an extractor configured to process an oil-containing feedstock. The extractor receives the oil-containing feedstock and conveys the material from an inlet to an outlet through the extractor. The extractor also receives an alcohol-based solvent at a solvent inlet and conveys the solvent through the extractor to a solvent outlet. The alcohol-based solvent may be ethanol. A concentration of oil in the feedstock may decrease as the feedstock moves through the extractor from the inlet to the outlet while the concentration of the oil in the solvent increases.

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.
