Conclusion
In this study, the reactive extraction of HGA by Ph3PO
was examined. The highest extraction efficiency of 86 % was achieved by
Ph3PO in the presence of isobutanol. Methyl ethyl ketone
gave 84 % extraction efficiency. A remarkable improvement was achieved
by oleyl alcohol and dimethyl adipate. The physical extraction
efficiencies with oleyl alcohol and dimethyl adipate alone were 23 and
21 %, respectively. Whereas, their extraction efficiencies reached up
to 61 and 76 % in the presence of 44 % Ph3PO
concentration by volume in the organic phase, respectively. The loading
factor values were less than 0.5, proving the 1-1 acid-extractant
complexation. The acid-extractant complex formations were also examined
by equilibrium constant (KE) values. The necessary
number of theoretical units to design an extraction column was found to
be between 2 and 4. From the thermodynamic study results, this examined
reactive extraction process was revealed to be spontaneous, exothermic
and feasible in nature. In this work, we presented the Gradient Boosting
algorithm, which comprises a systematic strategy for building
forecasting committees. The use of this algorithm in chemical
engineering prediction problems is still quite recent, but the results
presented in this work are encouraging.
