In this research, ZL leaves extract was used as a new friendly inhibitor for improving CS corrosion resistance in a 1.0 M HCl solution. The extract performance was evaluated by PDP and EIS techniques. The outcomes of this investigation showed that corrosion IE% of ZL leaves C2H5OH extract raised from 86 to 95%, with concentrations from 1 to 3 g/L. EIS method confirmed that the extract IE% was stable in the long-term. However, when the test temperature increased from 293 K to 323 K, IE% decreased from 95 to 90%. PDP experiments results revealed that ZL leaves extract operated as a mixed-type inhibitor, with anodic predominance.

Corrosion of metals and its alloys destroys our properties, our environment, and our lives. Thus, corrosion control includes a range of developed treatments that take into account material properties, environmental characteristics, and process cost. Typical corrosion inhibitors are known for their excellent efficiency and show great promise. However, they become less used because they cause serious toxicity issues on the environment and affect human and animal health. In recent years, research has intensified on the development of green chemistry technologies, which offer new methods of synthesis and extraction of various non-toxic materials (plant extracts, oils, amino acids, rare earths, etc.), which are highly effective, environmentally acceptable, economical and easily available inhibitors. This chapter deals with a description of corrosion inhibitors with a particular emphasis given to the discussion on the different characteristic features of the green corrosion inhibitors reported in the literature as a comparative view of toxic inhibitors.

“…In petroleum production, oxidation leading to corrosion is controlled by antioxidants, while corrosion inhibitors hinder oxidation through adsorption on reactive sites of potentially catalytic metal surfaces forming a monomolecular layer of the functional group that prevents metal contacting directly with the fuel [11]. For example, an eco-friendly formulation of Opuntia dillenii seed oil was reported to act as a corrosion inhibitor to protect iron in an acidic environment, such as acid rain [12]. This oil is a significant source of fatty acids, sterols, and vitamin E, which forms a barrier layer on the iron surface and minimize the contact between the metal surface and the corrosive solution [12].…”

Metal Rod Surfaces after Exposure to Used Cooking Oils

et al. 2021

Used cooking oils (UCOs) have a high potential as renewable fuels for the maritime shipping industry. However, their corrosiveness during storage and usage are some of the concerns yet to be investigated for addressing compatibility issues. Thus, the corrosion of steels and copper exposed to the UCOs was studied through the immersion of metal rods for different periods. The changes on the rod surfaces were analyzed with a scanning electron microscope (SEM). After the immersion, the copper concentration dissolved in the bio-oils was measured using inductively coupled plasma-optical emission spectrometry (ICP-OES). The free fatty acids and glycerides were analyzed using gas chromatography with flame ionization detection (GC-FID). The acid number (AN), water concentration, as well as density and kinematic viscosity of the bio-oils were determined with standard methods. The UCOs with the highest water content were corrosive, while the oils with lower water concentrations but higher ANs induced lower corrosion. After mixing two different UCOs, the metal corrosion decreased with an increasing concentration of the oil with lower corrosive properties. The lower corrosion properties were most likely due to the monounsaturated fatty acids, e.g., oleic acid in oils. These acids formed a barrier layer on the rod surfaces, thereby inhibiting the permeation of oxygen and water to the surface. Even adding 0.025 wt% of tert-butylamine decreased the corrosivity of UCO against polished steel rod. The results suggested that mixing several oil batches and adding a suitable inhibitor reduces the potential corrosive properties of UCOs.
