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 18):
A fractionation system for fractionating a first material from a feed stream of the first material and a second material, the system comprising:\n a column comprising a top, a bottom and a sidewall extending therebetween; a dividing wall extending all the way from the top to the bottom and between sides of the sidewall so as to divide a first side of the column from a second side of the column, so the first side is not in fluid communication with the second side through the wall; a feed inlet in the sidewall for introducing the feed stream into the column; a vapor discharge at the top of the column in the first side, a vapor duct having a first end at said vapor discharge, a second end of said vapor duct at a vapor entry at a bottom of the column in the second side, wherein said vapor duct extends through the column; a liquid discharge at the bottom of the column in the second side, a liquid duct having a first end at said liquid discharge, a second end of said liquid duct at a liquid inlet at a top of the column in the first side; a bottoms outlet in the bottom of the column on the first side; and an overhead outlet in the top of the column on the second side.
