Electrochemical and Quantum Chemical Studies on the Corrosion Inhibition Potential of Camellia sinensis Leaves Extract for Carbon Steel in Produced Water

Abstract

The present study evaluates the effect of Camellia sinensis leaves (CSL) extract on the corrosion inhibition of carbon steel in produced water using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and computational methods. The chromatographic investigation of the extract was performed by HPLC. It was found that CSL extract serves as a mixed-type corrosion inhibitor and its inhibitive performance increases with concentration. The corrosion inhibition was assumed to occur via adsorption of the primary constituents of CSL extract. Surface analysis (SEM and FTIR) was also carried out to establish the mechanism of corrosion inhibition. The outcomes obtained from the computational study were found to confirm experimental data.

Novel Biosurfactants for Effective Inhibition of Gas Hydrate Agglomeration and Corrosion in Offshore Oil and Gas Pipelines

“…The key solution to solving the H 2 S−CO 2 corrosion problem is the injection of a very low dose of corrosion inhibitors (BAAs) inside the oilfield systems. Since mild steel is positively charged in either an inhibited or uninhibited H 2 S/CO 2 SOPW, 82 the anionic part of BAA molecules can be adsorbed at the metal− solution interface. 83 The tendency of BAAs to adsorb on the MS surface through their heteroatoms (O and S) is the major parameter for slowing of the corrosion rate of MS specimens in H 2 S/CO 2 SOPW electrolyte.…”

Green approach towards corrosion inhibition of carbon steel in produced oilfield water using lemongrass extract

“…This electrical model was chosen in the light of our previous work. 18 It is usually done in electrochemical systems with rough or porous solid surfaces, two constant phase elements (Q 1 and Q 2 ) are used instead of the two real capacitance elements to give improved tting. The model consists of two parallel time constants (Q 1 R 1 W) and (Q 2 R 2 ) connected in series with the solution resistance (R s ).…”

“…In continuation of our work on development of green compounds as corrosion inhibitors in petroleum led, 18 we have studied the inhibiting effect of lemongrass (cymbopogon citratus) extract for carbon steel corrosion in produced oileld water using weight loss method, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations.…”

Synthesis, characterization, synergistic inhibition, and biological evaluation of novel Schiff base on 304 stainless steel in acid solution

“…However, due to its simplicity and affordability, using an inhibitor is thought to be the best method among them 1 – 5 . As corrosion inhibitors, a variety of inorganic and organic, those with aromatic rings, N, S, and O atoms, have been researched and used more effectively, more affordable, environmentally benign, and non-toxic 6 – 8 . The best approach to stop the corrosion of 304 SS and GS in acidic is to utilize specific morpholinobenzyldine compounds 9 .…”
