    Abstract: A mass transfer column comprising: a shell (12); an open internal region (14) defined by said shell; and a mass transfer assembly (16) positioned in the open internal region (14), the mass transfer assembly (16) comprising: a dividing wall (18) forming first and second sub-regions; one or more zones of mass transfer structures positioned in the first and second sub-regions (22 and 24); and a liquid flow divider (48) positioned above the dividing wall (18) for delivering a volumetric split of liquid to the first and second sub-regions. The liquid flow divider (48) may comprise a moveable weir (68) or a valve (180) in order the change the ratio of liquid flow between the two sub-regions.

    Abstract: A mass transfer column is provided in which a shell is formed of one or more side walls having an exoskeleton. The exoskeleton includes a plurality of vertical trusses joined together by crossing rails. An inner skin is supported by the vertical trusses and rails and, together with a top and bottom of the shell, defines an open internal region that may be pressurized and in which mass transfer process may occur. Horizontally extending beams that may be in the form of trusses span the open internal reaion and are supported by the exoskeleton. Internals such as structured packing may be supported on the horizontally extending beams.

    Abstract: A vapor distributor for use in an internal region of a mass transfer column to receive and redistribute a vapor stream when it is introduced radially into the internal region through a radial inlet in a shell of the mass transfer column. The vapor distributor includes a plurality of multiple-sided elongated deflectors arranged in a descending array and a pair of braces that extend longitudinally across the array of elongated deflectors and hold them in spaced apart and side-by-side relationship to each other. Each of the elongated deflectors has a deflecting surface that faces toward the radial inlet to redirect and redistribute the radially-introduced vapor stream. The braces each include a strut that may also redirect and redistribute the vapor stream.

    Abstract: The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

    Abstract: An automatic control system is provided for controlling the operation of a mass transfer system that includes a mass transfer column. The automatic control system includes a field data collection device that collects process data from the mass transfer system, a data collection module for receiving and storing process data received from the field data collection device, and an online simulator that includes a column simulation module for calculating a column performance parameter from the process data.
