Removal of Oil Spills from Salt Water by Magnesium, Calcium Carbonates and Oxides

摘要

Magnesium, calcium carbonates and oxides that are widely used in cement industries were employed in studying sorption of petroleum oil spills from salt water at different condition parameters such as temperature, loading weight, degree of salinity. Treatment of magnesium, calcium carbonates and oxides by dodecyl benzene sulphonic acid alcohol was studied to enhance the sorption efficiency. Results obtained showed that treated MgCO3, CaCO3, MgO and CaO with dodecyl benzene sulphonic can sorb oil by 0.95, 1.25, 78, 0.56 times its weight respectively; untreated materials can sorb oil by 0.49, 0.76, 0.44, 0.32 its weight. Characteristics of crude oil and the used materials were investigated by FTIR, X - Ray Fluorescence, Inductive Coupled Plasma, Pour Point and Thermostatic Water Bath instruments. Determination of the amount of crude oil in water was done by extracting the crude oil in tricholorotrifluoroethane and measuring absorbance by FTIR spectrometer. @JASEM
