Abstract:
|
Liquid-liquid equilibrium (LLE) data are important for designing and modeling of process equipment. In this
article, the group method of data handling (GMDH) technique has been used to estimate LLE data of the quaternary
system of corn oil + oleic acid + ethanol + water at 298.15 K. Using this method, a new model has been proposed
that is suitable for use in predicting LLE data. The equilibrium data presented herein were predicted using the
GMDH model. To evaluate the performance of the GMDH method, we compared the data predicted using the
proposed model with experimental data. Moreover, we compared the deviation between the experimental data and
the data estimated with the GMDH. We also used the deviations of some existing models for the comparison. The
results show that the proposed model can be used as an efficient tool for estimating LLE data. |
