  • Patent number: 11667547
    Abstract: Apparatus and method for separating oil from water in produced oil without requiring large separation tanks in which the fluid is heated, using a simple, energy efficient separation process, are described. Centrifugal forces, by themselves, are not effective for completely separating a two-component fluid, especially when the densities of the fluids are similar, such as for heavy oil. By combining both primary and secondary acoustic forces, and taking advantage of centrifugal forces from fluid flow, such that acoustic radiation forces initiate the process of droplet accumulation, and contribute to droplet coalescence, centrifugal separation is enhanced.

  • Patent number: 11639297
    Abstract: The direct solar desalination system with enhanced desalination has a main chamber having a slanted transparent top and vertical sidewalls. Saltwater is fed to the top of a series of plates, with the top plate and every other plate slanting into the chamber, while the intervening plates slant back toward the chamber wall. The lower edge of the plates that are slanted into the chamber have a plurality of copper channels or wires extending between the plate's edge and the opposite chamber wall. Saltwater that does not flow down the channels/wires drips down to the next plate and so forth, and any remaining saltwater is collected at the bottom of the chamber. The channels/wires are coated with a photothermal layer to enhance evaporation. The fresh water condenses on the bottom surface of the slanted top, flows down the surface, and is collected at the bottom of the shortest sidewall.

  • Patent number: 11617969
    Abstract: Systems and methods for the controlled release of a guest composition that is sequestered within a host composition made up of an anisotropic fluid are disclosed. The guest composition is immiscible in the host composition, thus forming an interface between the compositions upon which elastic repulsion forces act to prevent the release of the guest composition from the host composition. The disclosed systems and methods work by changing the elastic repulsion forces and/or introducing one or more counter forces such that the elastic repulsion forces are no longer sufficient to prevent release of the guest composition. Exemplary methods include mechanically changing the host material (e.g., changing its temperature) or inducing a chemical (e.g., electrostatic) attraction sufficient to overcome the elastic repulsion forces. The disclosed systems and methods can be used for a variety of applications requiring “on-demand” delivery of a chemical composition.
