| 20100200512 | Mixed hydrophilic/hydrophobic fiber media for liquid-liquid coalescence - An immiscible lipophilic or hydrophilic liquid phase separated respectively from a continuous hydrophilic phase or a lipophilic phase liquid. Fibers having hydrophilic and hydrophobic properties are mixed, layered, etc., and formed into a filter. The separation mechanism involves capture of small droplets of the immiscible phase, coalescence of the small droplets into larger droplets as the immiscible liquid flows through the fiber filter, and release of the large immiscible droplets from the filter. With respect to separation of a hydrophilic immiscible fluid such as water in a lipophilic continuous fluid such as oil, the hydrophobic fibers will cause small water droplets to migrate towards the hydrophilic fibers whereby large droplets are formed on hydrophilic surface. The large droplets stay on hydrophilic fiber surface for extended periods of time and continue to coalescence until they are so large that they can no longer be maintained by the hydrophilic fibers and are released and drained off of the filter. In designing such filter, wettability of the filter media is an important parameter. The filter media can be designed by mixing hydrophilic and hydrophobic fibers in various proportions to achieve an optimum wettability range for separation of the immiscible liquid from the continuous phase liquid. The wettability of filter media can be characterized by a modified Washburn Equation. | 08-12-2010 |

| 20120125859 | METHOD FOR CONDITIONING AND PROCESSING WHOLE OR THIN STILLAGE TO AID IN THE SEPARATION OF AND RECOVER PROTIEN AND OIL FRACTIONS - The invention provides a method and apparatus for reducing the energy needed to process stillage in an ethanol refining operation. The method involves adding to stillage an effective amount of at least one processing aid. The flocculant induces the separation of insoluble material that would otherwise remain suspended in water but which impose a high shear energy cost on the refining processes. This allows for the removal of insoluble material that would otherwise be overlooked but which increase energy costs. This allows for more efficient and effective separation and recovery of insoluble fractions of the concentrated thin stillage that would otherwise be overlooked and lost in the process. Loss of these valued fractions as a result of traditional processing techniques and those requiring extensive additional energy input results in the loss of high value co-products to low revenue process streams. This allows stillage to be processed more rapidly with a lower energy cost and improved co-product recovery economics. | 05-24-2012 |

| 20130087507 | USE OF CACTUS MUCILAGE AS A DISPERSANT AND ABSORBANT FOR OIL IN OIL-WATER MIXTURES - Despite advances in off-shore oil exploration and drilling technology, accidental oil spills do occur. Depending on their magnitude and location, irreparable damage may be inflicted on marine and coastal ecosystems. Emulsification of a water/surfactant /oil system results in the production of oil droplets and this depends on the formulation and composition variables, mixing characteristics and system preparation. Thus, research is ongoing on improving methods of cleaning up oil spills. Cactus mucilage was used to disperse and absorb oil from a simulated oil slick in different salt concentrations. Results show correlations between emulsion properties and interfacial characteristics of mucilage as function of aqueous phase salinity. Mucilage powder added to the oil floating on the water dispersed the oil film and absorbed the oil while remaining afloat, facilitates removal of the oil-mucilage aggregate.

Spreading of oil can be reversed by reducing the surface tension of the seawater, for example by using a low concentration of a water-soluble surfactant, such as a non-ionic surfactant. A controlled amount of the surfactant may be continuously discharged at the inner-wall of a spill control boom surrounding the oil spill. The spilled oil is caused to retract away from the boom toward the center of the area encircled thereby, such that the oil layer becomes sufficiently thick to be more effectively removed mechanically. The surfactant also reduces the amount of oil on the spill control boom, whereby the boom can easily be removed from a remediated oil spill and reused at a later date without further cleaning. | 07-04-2013 |

| 20130270192 | MIXED HYDROPHILIC/HYDROPHOBIC FIBER MEDIA FOR LIQUID-LIQUID COALESCENCE - An immiscible lipophilic or hydrophilic liquid phase is separated respectively from a continuous hydrophilic or a lipophilic phase liquid. Fibers having hydrophilic and hydrophobic properties are formed into a filter. The separation mechanism involves coalescence of the small droplets into larger droplets as the immiscible liquid flows through the fiber filter, and release of the large immiscible droplets from the filter. With respect to separation of a hydrophilic immiscible fluid in a lipophilic continuous fluid, the hydrophobic fibers cause small water droplets to migrate towards the hydrophilic fibers whereby large droplets are formed on hydrophilic surface.
