Sažetak
Preliminary evaluations using a simple but reliable short-cut method indicated that a 15 component aromatic’s mixture can be separated very efficiently into four fractions according to given product specifications employing either a single or a multiple partition wall dividing wall column (DWC). The obtained results have been used to initiate rigorous simulations, to determine the number of stages required in different sections, as well as to obtain internal flows of vapour and liquid necessary for dimensioning and adequate (actual delivery prices) cost estimation. Comparison of total annualized costs indicates that more energy efficient complex configuration with three partition walls is a viable option in present case.
