  • Patent number: 9896398
    Abstract: A simulated moving bed process using dual, parallel rotary valves configured or plumbed to be operated independently in which the step times of the rotary valves are staggered. In embodiments, the second rotary valve is programmed to step about halfway through the step time of the first rotary valve. Staggering the step time of the parallel rotary valves, rather than utilizing simultaneous stepping, results in increased net composite paraxylene concentration of the extract stream, allowing for increased capacity of the simulated moving bed process and/or reduced energy consumption.

    Abstract: A novel process and apparatus is disclosed for performing chemical reactions. Highly compressed gaseous streams such as H2, CO, CO2, H2O, O2, or CH4 are raised to Mach speeds to form supersonic jets incorporating shockwaves. Two or more such jets are physically collided together to form a localized reaction zone where the energy from the shockwaves causes endothermic reactions wherein the chemical bonds of the reactant gases are broken. Between and among reactants molecular surface interaction and molecular surface chemistry take place. In the ensuing exothermic reactions a desired new chemical product is formed and this product is locked into a lower state of enthalpy (state of energy of formation) through adiabatic cooling by means of a free jet expansion.

  • Patent number: 8936757
    Abstract: Apparatuses and processes are provided for stripping gaseous hydrocarbons from particulate material. One process comprises the step of contacting particles containing hydrocarbons with a stripping vapor in countercurrent flow to remove at least a portion of the hydrocarbons with the stripping vapor to form stripped particles. Contacting the particles includes advancing the particles down a sloping element of a structured packing toward a reinforcing rod that is disposed along a lower channel portion of the sloping element. The particles are advanced over the reinforcing rod. The particles are contacted with the stripping vapor that is rising up adjacent to the lower channel portion.

  • Patent number: 8936761
    Abstract: Embodiments of apparatuses and risers for reacting a feedstock in the presence of a catalyst and methods for fabricating such risers are provided. In one example, a riser comprises a sidewall that defines a cylindrical housing surrounding an interior. The sidewall has a groove formed therein disposed about the interior. A plurality of baffle sections is disposed in the groove. The baffle sections are configured to be packed together in the groove to define a packed condition and to be moved in the groove so as to spread out the baffle sections from the packed condition to define an expanded condition and form a baffle ring. The baffle ring extends inwardly in the interior.

  • Publication number: 20150017085
    Abstract: Methods and apparatus for precipitating dissolved materials from a solution involve reduction of fines. In an embodiment, the method comprises: introducing a solution into a reactor, causing the dissolved materials in the solution to precipitate into crystals under a first reaction condition, adjusting the reaction condition from the first reaction condition to a second reaction condition, maintaining the reaction condition in the second reaction condition to cause a sub-population of the crystals to dissolve, and adjusting the reaction condition from the second reaction condition to the first reaction condition. In an embodiment, the apparatus comprises a reaction tank, a recycling path and at least an acid injector which is configured for dosing an acid into solution flow in the recycling path.

  • Publication number: 20150011811
    Abstract: Disclosed is a system and method for cooling and relieving pressure of the bottom product produced by the fluidized-bed gasification of biomass, brown coal, or hard coal having a high ash content. With such a method and system, an economic solution for cooling and pressure expansion of the bottom product produced is to be ensured, which is achieved by the bottom product leaving the fluidized bed at a maximum of 1500° C. and a pressure of up 40 bar, being fed to an intermediate store, then being fed from the intermediate store to a pressure tank having a cooling system, and then being fed to a pressure release system.
