“…Corrosion inhibitors are proven to be effective in reducing the metallic corrosion and thus preserving the service life and performance of assets (18). Furthermore, a recent study revealed that some agro-based inhibitors can offer additional benefits as "cryoprotectants," i.e., significantly lowering the freezing point of salt brine (19), which may translate to reduced salt application rates needed under cold weather scenarios.…”

A liquid mixture was developed from waste peony leaves through a zero-waste chemical/biological process. The inhibition effect of different concentrations of peony leaves derived solution (0-3 vol.%, PLS0-3) on C1010 carbon steel in 3.5 wt.% NaCl was investigated over time using electrochemical measurements. Chemical analyses were performed to reveal the main compounds of this inhibitor. Surface analyses together with water contact angle measurements were employed to study the characteristics of the steel surface affected. Semi-empirical calculations with PM3 method were used to find the relationship between molecular structure and inhibiting effect of PLS. The inhibitor was stable over time and its main active ingredients were C 19 H 27 N 4 O 10 P and C 17 H 16 N 3 O 9 P that adsorb onto the steel surface, block cathodic active sites, make the surface hydrophobic, decrease the surface free energy, and facilitate the formation of a passive layer. A good correlation was found between experimentally determined inhibition efficiency and theoretically calculated properties of PLS.ARTICLE HISTORY

“…Most of the well-known corrosion inhibitors are organic compounds containing nitrogen, sulfur, or oxygen atoms (Cheng et al, 1999;Prabhu, Venkatesha, Shanbhag, Kulkarni, & Kalkhambkar, 2008;Samide, Bibicu, Rogalski, & Preda, 2004;Verma, Quraishi, & Ebenso, 2013;Wang, 2001). It has been found that most of the organic inhibitors act by adsorption on the metal surface (Abd El-Rehim, Ibrahim, & Khaled, 1999;Li et al, 2014). This phenomenon is influenced by the nature and surface charge of metal, by the type of aggressive electrolyte, and by the chemical structure of inhibitors (Thomas, 1981).…”

Novel Schiff base amino acid as corrosion inhibitors for carbon steel in CO 2 -saturated 3.5% NaCl solution: experimental and computational study Abstract: The corrosion inhibition and adsorption behavior of some novel Schiff bases based on amino acids on carbon steel in CO 2 -saturated 3.5% NaCl solution at 50°C was investigated using gravimetric, potentiodynamic polarization, linear polarization resistance corrosion rate, and scanning electron microscope (SEM)/energy-dispersive X-ray spectroscopy analysis (EDAX) techniques. Results show that the inhibition efficiency increases when the inhibitor concentration increases. Potentiodynamic polarization curves reveal that the used Schiff bases are mixedtype inhibitors. Experimental data indicate that these Schiff base inhibitors adsorb at the carbon steel/solution interface according the Langmuir adsorption isotherm. SEM/EDAX was used to examine the surface morphology of carbon steel samples in the absence and presence of the inhibitors. Quantum chemical calculations were further applied to explain the experimental results. . His current research interests are quantum chemistry and materials design.

“…The effect of corrosion inhibitors has been widely studied in the oil and gas production, and these experiments were normally conducted at low CO 2 partial pressure or other corrosive environments, which were summarized by Sim, Cole, Choi, and Birbilis (2014b) and Li et al (2014). However, investigations so far focusing on the effect of inhibitor on the corrosion behavior of steels under SC CO 2 conditions are very sparse.…”

Carbon dioxide (CO 2 ) corrosion at low partial pressure has been widely recognized, but research on supercritical CO 2 (SC CO 2 ) corrosion is very limited. By far, investigations on steel corrosion under SC CO 2 conditions have mainly focused on the corrosion rate, structure, morphology, and composition of the corrosion scales as well as the electrochemical behaviors. It was found in aqueous SC CO 2 environment, that the corrosion rate of carbon steel was very high, and even stainless steels (13Cr and high-alloy CrNi steels) were subjected to some corrosion. Inhibitor could reduce the corrosion rate of carbon steels and stainless steels, but none of the tested inhibitors could reduce the corrosion rate of carbon steel to an acceptable value. Impurities such as O 2 , SO 2 , and NO 2 and their mixtures in SC CO 2 increased the corrosion rate of carbon steel. However, the existing studies so far were very limited on the corrosion mechanism of steels in SC CO 2 conditions. Thus, this paper first reviews the finding on the corrosion behaviors of steels under SC CO 2 conditions, points out the shortcomings in the present investigations and finally looks forward to the research prospects on SC CO 2 corrosion.
