  • Patent number: 10293275
    Abstract: Embodiments of the present disclosure include a matrix of raw materials, also referred to as a poly-grain grind matrix. In some embodiments, the matrix of raw materials may form an interlocking network of varied particle grind sizes that allows the particles to nest and interlock with one another when packed into an extraction vessel, so that most, but not all of the interstitial spacing within the matrix of raw materials is closed. Additionally, the varied particle sizes may be selected by pre-determined weight ranges and size classifications so that the particle grind sizes achieve the desired consistency uniformity. This may allow the network of particles to act as its own best filtering agent during the extraction process. Moreover, the nesting and interlocking network of the particles within the matrix of raw materials may allow the particles to be effectively packed within the extraction column, thus allowing for an efficient and high quality extraction to be performed consistently each and every time.

  • Patent number: 9228132
    Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

    Abstract: The moisture absorption capacity of biofuels can be more or less 10 times that of fossil diesel oil, causing biofuels to form acids that induce metal corrosion and form deposits in the fuel tank and pipe lines. Methods for removing moisture from stored biofuels and plant oils are described wherein glycerol is used as a solvent to extract the moisture from the bioliquid or oil, comprising the steps of placing the biofuel or oil in fluid contact with glycerol, incubating for a time, and then removing the glycerol. A cellulous ester dialysis or other semi-permeable membrane may be used to prevent the glycerol from contaminating the biofuel while allowing moisture to pass. Crude glycerol produced as a byproduct of biodiesel production may be used in the method of the disclosed invention with good result. Preferred embodiments of apparatus that employ the method of the subject invention are described.

  • Patent number: 8753514
    Abstract: An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gases. The constituent gases and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products.

    Abstract: A process and apparatus for refining iron from high-phosphorus content iron ores. The process involves mixing a high-phosphorus iron oxide ore and an alkaline solution of pH between about 12.5 and 13.5, screening the mixture by gravity to separate an alkaline-high-phosphorus solution from a low-phosphorus iron ore; and treating the low-phosphorus iron ore with lime and a natural gas.

  • Publication number: 20140073038
    Abstract: In one aspect of the invention, a method recovers oil from a concentrated byproduct, such as evaporated thin stillage formed during a dry milling process used for producing ethanol. The method includes forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct. Further, the step of separating the oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage.

  • Patent number: 8597517
    Abstract: A process for recovering ionic liquids comprising the steps of: providing a first ionic liquid mixture, the first ionic liquid having a halogen metallate anion, the mixture containing an organic solvent; adjusting the pH of the mixture to pH 7-10 by the addition of a base to form a first precipitate; separating the first precipitate from the mixture; removing the organic solvent from the first mixture to form a second precipitate and separating the second precipitate from the first mixture; acidifying the resulting mixture to pH 2-7 by the addition of an acid; and drying the mixture to obtain a second ionic liquid having a halogen anion.

  • Patent number: 8591739
    Abstract: The present invention discloses a method and apparatus for separating particles and dissolved matter from a fluid stream. Specifically, the present invention includes a first pressure source which transports untreated fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation physics allowing the desired fluid to penetrate and pass into and through the filter media. The filtered fluid is then transported to a collection tank. The contaminant particulate matter retained on the exterior of the filter media may be removed by the instantaneous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or a concentrator for further treatment.

  • Patent number: RE45869
    Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.
