Adsorption of BTX and PAHs by Polymeric Resins Packed in a Fixed Bed: Semi-Industrial Evaluation

Polymeric resins were synthesized by suspension polymerization on a pilot scale and packed in an acrylic column for use in a semi-industrial elution system, to study their behavior as adsorbents of oily water. The performance in removing benzene, toluene and xylene (BTX) was greater than 95.9 %, and the efficiency in retaining polyaromatic hydrocarbons (PAH) remained near 96.3 %.  

Methods for Determination of Oil and Grease Contents in Wastewater from the Petroleum Industry

Infrared spectrometry and spectrofluorimetry methods were correlated in the measurement of oil concentration in produced water. Furthermore, we compared colorimetry and gravimetry techniques. Adsorption experiments were performed in synthetic oily wastewaters by polymer compounds based on poly(hydroxyethyl acrylamide  and polypropylene. The residual oil content was used in the techniques correlation.
