Abstract
A fully thermally coupled distillation structure designed to overcome hydraulic limitations in the past has been revealed for separating a multi-component feed stream into three product streams. The fractionation apparatus is equipped with at least one condenser and one reboiler to provide fractionation efficiency surpassing the PETLYUK system. Further, the fractionation apparatus includes innovative designs to enable hydraulically balanced and energy efficient operation at various feed rates, compositions and product specifications.

A system comprising of:
- An apparatus further comprising of:
- 1. at least one reboiler, at least one condenser, means for mass transfer in between said reboiler and said condenser,
- 2. means for communicating and means for rationing internal vapor traffic between desirous zones within said apparatus,
- 3. means for communicating and means for rationing internal liquid traffic between desirous zones within the apparatus,
- 4. means for placing at least one vapor stream at a suitable location within the apparatus to minimize mixing inefficiencies,
- 5. means for placing at least one liquid stream at a suitable location within the apparatus to minimize mixing inefficiencies,
- means for maintaining hydraulic balance at changing operating conditions and control of the apparatus thereof,
- to separate at least one feed stream containing at least two components, into at least one overhead distillate stream, at least one side draw stream and at least one bottom stream;
- each such said product stream contains different averaged volatility.
A divided wall column, comprising of an internal longitudinal partition resulting in creating a prefractionation zone and a main fractionation zone, wherein an internal liquid flow, selected from one of the following groups consisting of
- a liquid stream exiting from said prefractionation zone and
- a liquid stream exiting from said main fractionation zone;
- is provided with means for bypassing at least one tray below said partition.
