(2004) has shown good results relative to the experimental tests. Among the theoretical models, OlujiД‡ et al. The low liquid flow rates in the top section of the column are a source of error for HETP evaluation by the models therefore, more reliable HETP values were found in the bottom section, in which liquid flow rates were much greater. As the laboratory distillation column was operated continuously, different HETP values were found by the models investigated for each section of the column. Modifications concerning calculation of specific areas were performed on the correlations in order to fit them for gauze packing HETP evaluation. The theoretical models chosen for HETP evaluation were: Bravo, Rocha and Fair (1985) Rocha, Bravo and Fair (1993, 1996) Brunazzi and Pagliant (1997) Carlo, OlujiД‡ and Pagliant (2006) OlujiД‡ et al., (2004).

The results of PRO/IIВ® were very similar to the analysis of the products obtained during continuous operation, therefore permitting the use of the properties calculated by that software on the theoretical models investigated. Prior to the experimental tests, simulation studies using commercial software PRO/IIВ® were performed in order to establish the optimum operational conditions for the distillation, especially concerning operating pressure, top and bottom temperatures, feed location and reflux ratio.

Six HETP correlations available in the literature were compared in order to find out which is the most appropriate for structured packing columns working with medium distillates.

The main purpose of this work was to evaluate HETP of a structured packing laboratory scale distillation column, operating continuously. Several tests with a hydrocarbon mixture of known composition (C8-C14), obtained from DETEN Chemistry S.A., have been performed in a laboratory distillation column, having 40mm of nominal diameter and 2.2m high, with internals of Sulzer DX gauze stainless steel structured packing.
