ALINA BARBULESCU, CLAUDIA IRINA KONCSAG Mass Transfer at Propanethiol - Buthanethiol Alkaline Extraction from Sour Petroleum Fractions


Abstract:

The present work is a study of the extraction of some mercaptans from the liquid hydrocarbon fractions with caustic solutions. The goal was to obtain a mathematical model for the estimation of mass transfer coefficients by processing data from laboratory and pilot scale extraction columns equipped with packing.The model was established taking into account the factors influencing the extraction: the acidity of the thiol, the alkaline solution concentration, the geometrical characteristic of the packing and the superficial velocity of the dispersed phase. The general equation is:

The model’s parametres were found for each thiol separately by applying a modified version of the least squares method. The validity of the model was checked using statistical tests on the errors.

Keywords: mass transfer, packed columns, modelling, errors analysis
