Modification of Punica Granatum Linne Husk Extract as Eco-Friendly Corrosion Inhibitors in Oil Fields
Abstract:
The pomegranate husk extract is modified by formaldehyde and diethylamine, the products have been investigated as corrosion inhibitors for Q235A steel used in oil fields. The inhibition efficiency of products have been measured by weight loss method with the concentration range from 10 mg/L to 1,000 mg/L in 1wt% HCl at different temperture. The inhibition efficiency of the modification product shows good inhibition efficiency after modified by formaldehyde and diethylamine, which is up to 89.31% at 60°C. The inhibitory effect of modification products is in accord with Langmuir adsorption equation.
