Abstract
Potential alternatives for a fully thermally coupled four-product dividing wall column are addressed,
emphasizing hydraulic design and column dimensioning aspects of importance for practical
implementation of multi-partition wall configurations. Utilizing an industrially relevant aromatics processing
plant case for evaluation and comparison of the cost-effectiveness of alternative configurations, this paper
focuses on a new, minimum energy, four-product dividing wall column with two overhead product streams.
