    Abstract: A highly efficient process is disclosed for making proppants from generally non-spherical or discretized raw material, such as naturally occurring sand or pelletized refractory material. In one embodiment of the process, the discretized material is heated by a counter-current flow of hot gas in a first Moving Bed Gas-Solids Direct Contact Heat Exchanger (MBGSDCHX). The heated discretized material is then further heated to a transformative temperature by a raw material transformation means to a partially or fully melted state in which the discretized raw material assumes generally spherical shapes. The spheres are then cooled by a counter-current flow of cold gas in a second MBGSDCHX. The cooled spheres are then size-classified for use as proppants. In an alternate embodiment, refractory raw material is melted and then discretized into molten drops. The molten drops are cooled and frozen into generally spherical shapes.

  • Patent number: 8455402
    Abstract: Fluid systems may contain elements to provide changes in bulk fluid density in response to various environmental conditions. One environmental driver to the variable density is pressure; other environmental drivers include, but are not limited to, temperature or changes in chemistry. The variable density of the fluid is beneficial for controlling sub-surface pressures within desirable pore pressure and fracture gradient envelopes. The variability of fluid density permits construction and operation of a wellbore with much longer hole sections than when using conventional single gradient fluids.

  • Patent number: 8420578
    Abstract: A low-density ceramic proppant is formed from a light aggregate of a natural mineral and a ceramic binding material in the form of a proppant granule. The light aggregate expands in volume when burnt so that the density of the aggregate is changed. A method of preparing a proppant material is carried out by pre-crushing and pre-mixing of raw components. This is followed by their granulation into proppant granules, drying and screening of the granules to a selected size. The raw components include at least a ceramic binding material and a light aggregate of a natural mineral that, when burnt, expands in volume so that the specific volume of the aggregate is changed. The burning of the light aggregate may be accomplished before or after the aggregate is mixed with the binding material.

  • Publication number: 20130009331
    Abstract: Provided is a process for production of composite fine particles with heterogeneous surfaces. The process ensures a high productivity and enables a voluntary control of particle diameters. Further, the process imposes no restrictions on heterogeneous substances added for functional expression, and allows a heterogeneous substance to be encapsulated in central portions of composite fine particle spheres. A composite film obtained by laminating two or more kinds of films is cut into minute pieces, followed by melting the same to obtain spherical minute pieces. Particularly, liquid films are separately formed with two or more kinds of liquids containing polymerizable monomers. Further, two or more kinds of films can thereby be obtained through polymerization. The two or more kinds of films thus obtained are then laminated to further allow polymerization to take place, thus obtaining the composite film.

  • Patent number: 8343395
    Abstract: A powder particle shaping device includes a closed cavity capable of changing between multiple shapes as an external pressure changes, and the closed cavity compresses and moves powder particles with which the closed cavity is filled full while the shape changes. A powder particle shaping method is further provided, which includes a. filling a cavity full with powder particles to be shaped; and b. applying a varying external pressure to make the cavity change repeatedly between multiple shapes, thereby making the powder particles under compression move and be subject to friction, where the cavity is kept in a closed state during an effective processing process. The shaping device and method have highly controllable shaping processing intensity of powder particles and stable processing strength, and thus are applicable to shaping and pulverization of various powder particles, and also applicable to pulverization and further shaping processing of dispersed agglomerates.
