Three-component distillation using structured packings: Performance evaluation and model validation

Experimental Characterization and Modeling of the Performance of a Large-Specific-Area High-Capacity Structured Packing

“…5 Evaluation of the total reflux and continuous distillation experiments performed recently with a mixture of methanol, ethanol, and water in a 0.22-m-internal-diameter column, equipped with a 250 m 2 / m 3 packing, indicated that even a significant fraction of water does not introduce any performance-deteriorating effect. 31 A plausible explanation for such a good efficiency as observed with the M/W system in the present study may be found in a beneficial effect of the rather short length of the bed used in this case (1 m). Namely, as demonstrated by Stichlmair and Fair, 32 a good initial distribution, which is observed after one element translated into that inherent to the size of the corrugations and the nature of surface, remains preserved within the first 5-6 elements.…”

Effective retrieval and new indexing method for case based reasoning: Application in chemical process design

“…In this section, various options of our CBR system are tested through the distillation of a three components mixture; methanol/ethanol/water. Mori et al (2006) have experimentally studied this distillation for different operating conditions: pressure, flow rates. These operating conditions define our target problem.…”

“…These operating conditions define our target problem. The goal of this example is to compare the solution proposed by the CBR system with respect to the type of the column packing used by Mori et al (2006).…”

Hydrodynamic‐analogy‐based model for efficiency of structured packing columns

“…For the verification, experimental data available in the literature are utilized. The results of pilot scale distillation tests were obtained at the University of Dortmund44, and at the Nagoya Institute of Technology 45…”
