Abstract.
The multivessel batch distillation column, as well as conventional batch distillation, may be operated in a closed (total reflux) mode where the products are collected in vessels along the column. We have previously proposed and simulated a feedback control strategy for the closed operation, where the idea is to indirectly adjust the vessel holdups by using the reflux flow out of the vessel to control the temperature at some location in the column section below. The feasibility of this scheme is here demonstrated experimentally on a laboratory scale multivessel column. The experimental column consists of a reboiler, two intermediate vessels and accumulator, where we separate a mixture of methanol-ethanol-propanol-butanol into almost pure components.

The paper presents the first published experimental work on the closed operation of batch distillation, as well as the first published results on the operation of a multivessel column.
