ABSTRACT:
An integrated distillation column having a partitioned stripping or absorption section is presented. The integrated stripping/distillation column comprises a single shell housing a refluxed absorption section and a reboiled stripping section. The stripping section is partitioned by a vertical wall into first and second separate portions having upper end in fluid communication the absorption section. The stripping portions include fluid isolated lower ends having separate reboilers. In the integrated absorption/distillation column, the absorption section is partitioned and separate reflux loops are provided for each portion of the absorption section. In such a manner, a two column distillation process can be combined into one for achieving space and equipment savings.
