About the Cover

Corrosion inhibition of low carbon steel in crude oil was investigated in the absence and presence of extracts from the root and the bark of Aacacia nilotica as a friendly corrosion inhibitor. The effect of temperature and inhibitor concentration was studied using the weight loss method. The result shows that extracts act as an inhibitor for low carbon steel in crude oil and reduce the corrosion rate. The inhibition efficiency increased with an increase in inhibitor concentration at a given temperature. The highest inhibition efficiency was 95.58% at 1000ppm of inhibitor concentration at 313K. The adsorption of the root and bark of Acacia nilotica extracts was found to obey the Langmuir adsorption isotherm model. The free energy values of adsorption were more than 20 kJ/mol, which indicates mixed modes of physical and chemical adsorption.
