  • Patent number: 9587192
    Abstract: Fine coal particles are dewatered by mechanically removing water from the coal particles by vibration assisted vacuum dewatering to form a coal particle filter cake. The filter cake typically has a water content less than 35% by weight, suitable for extrusion to form discrete, non-tacky pellets. The vibration assisted vacuum dewatering may operate at a vibration frequency in the range from about 1 Hz to about 500 Hz. The vibration frequency may be adjusted during the dewatering process. In some embodiments, the vibration frequency is increased as the moisture content of the coal particle filter cake is decreased. Washing the filter cake during dewatering removes soluble contaminants. Various vibration assisted vacuum dewatering devices may be used, including a vibration assisted rotary vacuum dewatering drum, a vibration assisted vacuum disk filter, and a vibration assisted vacuum conveyor system.

  • Patent number: 9561511
    Abstract: The present invention is a method for applying a gradient magnetic field to a paramagnetic supporting liquid containing a mixture of first particles and second particles to separate the mixture by particle type. A magnetic susceptibility of the first particles is lower than that of the liquid, and a magnetic susceptibility of the second particles is higher than that of the liquid. A gradient magnetic field is applied to the liquid in a separation tank provided with a magnetic filter and the liquid is stirred. The first particles float in the liquid by a magneto-Archimedes effect. A horizontal magnetic force acts on the first particles by the gradient magnetic field, so that the first particles travel to a region lateral to or outward from the magnetic filter and are gathered in the region. The magnetic filter is excited by the gradient magnetic field to catch the second particles.

  • Patent number: 9199217
    Abstract: Apparatus and methods for using acoustic radiation forces to order particles suspended in a host liquid are described. The particles may range in size from nanometers to millimeters, and may have any shape. The suspension is placed in an acoustic resonator cavity, and acoustical energy is supplied thereto using acoustic transducers. The resulting pattern may be fixed by using a solidifiable host liquid, forming thereby a solid material. Patterns may be quickly generated; typical times ranging from a few seconds to a few minutes. In a one-dimensional arrangement, parallel layers of particles are formed. With two and three dimensional transducer arrangements, more complex particle configurations are possible since different standing-wave patterns may be generated in the resonator.

  • Patent number: 8812236
    Abstract: A method for optimizing drilling fluids by creating a proper particle size analysis and distribution curve of particle sizing within drilling fluid. The particle size distribution curve is maintained with a maximum particle sizing of 6 microns so as to not allow for coarser drilled solids to degrade beyond the point of mechanical separation to prevent a build-up of low gravity solids that can no longer be removed from the drilling fluid during the drilling operation due to their size. An optimal drilling system requires that drilling fluids be modified through the following process to attain the appropriate particle sizing distribution to: make the most efficient use of the drilling operation, reduce the amount to drilling fluids utilized, and reduce formation damage. The method generates corrective actions to modify the drilling fluids or adjust solids control equipment parameters, to obtain a unique particle size distribution throughout the drilling process.

  • Patent number: 6974927
    Abstract: A method, apparatus, and system for optically sorting and/or manipulating carbon nanotubes by creating an optical dipole trap with a focused light source (e.g., a laser) are described in detail herein. In one representative embodiment, light from the light source may be directed onto a mixture of carbon nanotubes, the mixture including a target class of carbon nanotubes having dimensions (e.g., length and diameter) corresponding to particular electronic properties suitable for an application. By identifying a resonant condition corresponding to the target class of carbon nanotubes, and tuning the light source substantially to the resonant condition, an optical dipole trap may be created to attract carbon nanotubes of the target class to allow manipulation and/or sorting of the target class of carbon nanotubes from the mixture, or rotation of the nanotubes via rotation of a plane of polarization of the light, in an embodiment.

  • Patent number: 6849678
    Abstract: The current process for producing powder coatings can be replaced with a process utilizing supercritical fluids including polymer polymerization, compatibilized blending of powder coating ingredients, and particle size control and classification of the powder coating. Traditionally, powder coating resins are polymerized in solvent based system. Next, the resin is blended with additives in a twin screw extruder at high temperatures. The material is then ground and separated by particle size to form the finished powder coating. This invention replaces the previous process by performing all operations in a supercritical fluid, preferably, carbon dioxide. Polymerization is conducted at any pressure above critical pressure and temperature above critical temperature up to 190°C. Solubility of the polymer in the supercritical fluid allows for control and narrow distribution of the molecular weight and a polydispersity of about 2 or less.

  • Publication number: 20040091319
    Abstract: In a method for processing mixtures of material which contain a coarse component (3) and a predominantly cohesive fine component (4), both the mixture of material (2) and an added material (5) are delivered in continuous streams of material (11, 23) to a homogenizing and separating device (12). The homogenizing and separating device (12) serves to mix the added material (5) and the mixture of material (2) uniformly with one another, so as to put the fine component (4) of the mixture of material (2) into a state such that the fine components (4) can be separated from the coarse component (3). As a result of the continuous delivery of the mixture of material (2) and added material (5) to the homogenizing and separating device (12), and intimate mixing of the added material (5) and fine component (4) is achieved, so that the separation of the coarse component and fine component can take place directly in the same device.
