Experimental characteristics and modelling of a micro-tray distillation column

Experimental characteristics and modelling of a micro-tray distillation column

With the increased attention for micro-reactors in the chemical industry, the need for a suitable separation device on the micro-scale emerged as well. In this project, which is carried out cooperatively by TU Delft and DSM, a micro-distillation column will be put into operation and its operational possibilities will be explored. This is done by determining the separation performance for some reference mixtures, as well as flow characteristics for a range of conditions. In the future, the device could be employed in the purification of high-value chemicals in the lab stage of process development. It could furthermore serve as a tool to quickly assess the feasibility of a separation without the need of large quantities of feed material. Eventually, this should result in a shorter development time from lab scale to pilot plant and commercial production. An attempt to model the performance of the micro-tray column will be made which, in conjunction with experimental observations, could lead to a better understanding of the mass transfer process taking place inside micro-scale devices.
