  • Patent number: 9644138
    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. The cooled spheres are used as proppants.

  • Patent number: 8877107
    Abstract: The present invention relates to increasing the molecular weight during a thermal treatment of polyester in combination with a latent heat granulation. With the newly-developed method, an SSP (Solid State Postcondensation) can be directly combined with an underwater granulation. The method differs from a conventional solid state postcondensation by an increase in the molecular weight being possible without additional heat input and hence only by using the residual heat and the crystallization heat present. A characterizing element is improved water separation and dehumidification during the granulation. Only in this way is an increase in viscosity possible even with a small granulate of an average particle weight less than 20 mg.

  • Patent number: 7968020
    Abstract: Systems and methods for pelletizing hot asphaltenes are provided. Asphaltenic hydrocarbons can be dispersed to provide two or more asphaltenic particles. The asphaltenic hydrocarbons can be at a temperature of from about 175° C. to about 430° C. The asphaltenic particles can be contacted with a film of cooling medium. The film can have a thickness of from about 1 mm to about 500 mm. At least a portion of the asphaltenic particles can be solidified by transferring heat from the asphaltenic particles to the cooling medium to provide solid asphaltenic particles. The solid asphaltenic particles can be separated from at least a portion of the cooling medium.

  • Publication number: 20110070309
    Abstract: A method of preparing a pharmaceutical formulation comprises providing a solution comprising a first solvent, a second solvent, an active agent, and an excipient. The second solvent is less polar than the first solvent and the excipient is more soluble in water than the active agent. The first and second solvents are removed from the solution to produce particles comprising the active agent and the excipient. In one version, the excipient comprises an amino acid and/or a phospholipid. A pharmaceutical formulation made by a version of the invention comprises particles comprising an active agent and an excipient which at least partially encapsulates the active agent, wherein the excipient is more soluble in water than the active agent.

  • Publication number: 20100308483
    Abstract: A method for producing particles of predetermined sized and/or morphology of a substance in a production arrangement comprising the steps of: i) mixing within a spray nozzle and under flow conditions a stream of a liquid solution in which the substance is dissolved with a stream of a fluid, and ii) passing the mixture in the form of a spray through a spray outlet of the nozzle into a particle collecting container, and iii) separating and collecting within the container the particles. The characteristic feature is that the solvent is a liquid and the fluid is an aqueous liquid in a subcritical state. Preferred nozzles have two coaxial internal transport conduits. One aspect is a production arrangement that can be used in the method. Its characteristic features are functions for a) recycling fluid used in the process, b) for including a make-up agent in the fluid stream, and/or increasing production by paralleling particle formation.
