  • Gas-solids separator
    Patent number: 8287613
    Abstract: Gas-solids separator comprises a tubular housing, an inlet for introducing a gas-solids mixture at one end of said housing, which inlet is executed such that it imparts a swirl to the gas-solids mixture, a solids outlet opening at the opposite end of said housing, and a co-axially positioned tubular gas outlet conduit placed at an end of said housing, which separator further comprises a vortex stabilizer, comprising a pin placed on a stabilizing plate, in which separator the pin runs along the axis of the tubular housing and in which a passageway is provided through the stabilizer plate and the pin.
    Type: Grant

  • Process to separate particles from a particles-containing gas stream
    Patent number: 8025717
    Abstract: Process to separate particles from a particles-containing gas stream, by subjecting the particles-containing gas stream to a centrifugal separation step, wherein the particles-containing gas stream is separated in a gas rich flow and a particles-rich flow and wherein the particles-rich flow is cooled from a temperature in the range from 600 to 800° C. to a temperature in the range from 200 to 450° C. before it is subjected to a second separation step, wherein particles are separated from the particles-rich flow.
