  • Mass transfer process
    Patent number: 6089550
    Abstract: A dual flow mass transfer process is provided which employs a dual flow mass transfer tray having perforations, at least some of which are provided with vapor flow deflectors to deflect the flow of vapor rising through the perforations to give the vapor flow an increased horizontal component.
    Type: Grant
    Filed: September 22, 1998
    Date of Patent: July 18, 2000
    Assignee: Norton Chemical Process Products Corporation
    Inventors: Frank J. Petschauer, Richard P. Hauser, Frank Rukovena
  • Mass transfer device
    Patent number: 5911922
    Abstract: A mass transfer device is provided in the form of a tray having moveable valves which includes perforations spanned by bridge members shaped to divert liquid flowing in the design flow direction around the perforation such that gas rising through the perforation causes the valve to open and then encounters the liquid flow essentially at right angles.
    Type: Grant
    Filed: May 6, 1998
    Date of Patent: June 15, 1999
    Assignee: Norton Chemical Process Products Corporation
    Inventors: Richard P. Hauser, Bruce C. Taylor, John Harris, Joe Schirra, Frank Rukovens

  • Fractionation trays
    Patent number: 5618473
    Abstract: A fractionating column is provided which has perforated fractionating trays and downcomers allowing liquid to flow from one tray to the tray immediately below, said downcomers being provided with radial outflow ports directing downflowing liquids towards the column wall rather than onto the surface of the tray directly below the downcomer. This permits at least a portion of the under-downcomer area to be perforated thereby increasing the capacity of the tray for vapor/liquid contact and ensuring that weeping of the liquid through the perforations is avoided without need for an increase in vapor pressure.
