  • Apparatus for treating a gas stream
    Patent number: 9512518
    Abstract: An apparatus for treating a gas stream. A plasma generator generates a plasma flare. A first inlet conveys the gas stream into the apparatus. A reaction chamber is located downstream of the plasma generator in which gas is treated. A second inlet receives a liquid into the apparatus for establishing a liquid weir over an interior surface of the reaction chamber for resisting accumulation of solid deposits on the interior surface. A weir guide has an outer annular surface for directing liquid over the interior surface and an inner annular surface in flow communication with the outer surface so that liquid flows form the outer surface to the inner surface to resist depositing on the inner surface.

  • Apparatus for treating a gas stream
    Patent number: 9371581
    Abstract: In an apparatus for treating a gas stream, a plasma generator comprises an electrode for energizing a source gas to generate a plasma flare by application of a high voltage. An inlet allows the gas stream into the apparatus and directs it into the generated plasma. A scraper is fitted for reciprocating movement from a first position to a second position for scraping a surface to remove solid deposits accumulated on the surface.
