  • Patent number: 9023425
    Abstract: Fluidized bed reactor systems for producing high purity silicon-coated particles are disclosed. A vessel has an outer wall, an insulation layer inwardly of the outer wall, at least one heater positioned inwardly of the insulation layer, a removable concentric liner inwardly of the heater, a central inlet nozzle, a plurality of fluidization nozzles, at least one cooling gas nozzle, and at least one product outlet. The system may include a removable concentric sleeve inwardly of the liner. In particular systems the central inlet nozzle is configured to produce a primary gas vertical plume centrally in the reactor chamber to minimize silicon deposition on reactor surfaces.
    Type: Grant

  • Patent number: 8851110
    Abstract: A multi-phase fluid is split in a flow splitting device that includes a feed pipe in which a flow redistribution element induces tangential motion in the phases such that the denser phase is forced to redistribute around the periphery of the feed pipe. The so redistributed flow is then split into two or more distribution conduits that are typically perpendicular to the flow direction of the feed flow. Most typically, the feed pipe is in a vertical position.

  • Patent number: 7281702
    Abstract: A flow distribution device (100) has a vane distributor (111) at least partially disposed within a cartridge (102) and is operationally coupled to a second distributing device (112) that receives output from the vane distributor (111) Especially preferred flow distribution devices (100) are disposed within a vessel containing a contact bed, and may include at least a second vane distributor (112) within the cartridge (102), wherein the vane distributors (111, 112) are preferably swirl-inducing vane distributors (111, 112).
