MATHEMATICAL MODELLING FOR PHENOLATION OF SPENT SULFITE LIQUOR Autori: Andrei Ionuţ SimionData aparitiei: Aprilie / 2018 Revista: Environmental Engineering and Management Journal › Vol. 17 › Nr. 4 ISSN: 1843 - 3707 N.A.
In this study major factors affecting the phenolation process of lignosulfonate (LS) waste liquor (recovered from pulp and paper industry) were optimized in order to improve LS substitution for replacing petroleum-based phenols during phenolic resin manufacturing. Four different parameters, namely phenol/lignosulfonate ratio, time, temperature and lignosulfonate waste liquor concentration, were varied in an experimental program having as response function the reaction yield. Response Surface Methodology (based on central composite or Box-Behnken designs) and Artificial Neuronal Network were applied for establishing the process parameters impact on phenolation yield. |
