Abstract:
An apparatus and process doubles the number of trays in a single fractionation column. A dividing wall is used to isolate a first side from a second side and fractionation on trays on each side is independent of the other. A transition vapor stream is ducted from a top of a first side to the bottom of the second side, and a transition liquid stream is ducted from a bottom of the second side to the top of the first side.

Claim (Index 12):
A process for fractionating a first material from a feed stream of the first material and a second material, the process comprising:\n feeding the feed stream to a fractionation column; passing a transition vapor stream from a top of the first side of the column to a bottom of a second side of the column; passing a transition liquid stream from the bottom of the second side of the column to a top of the first side of the column; withdrawing an overhead vapor stream from a top of the second side of the column; and withdrawing a liquid stream from the bottom of the first side of the column.
