“…Therefore, various methods have been developed over the years for corrosion detection and decrease [ 5 ] and for material protection [ 6 , 7 , 8 ], among which the use of corrosion inhibitors [ 9 ] have been reported to decrease the negative effects of corrosion by more than 20% [ 10 ]. Existing research targets a wide range of corrosion inhibitors, with concern towards environment friendly technologies, the use of green inhibitors alone (e.g., Ircinia strobilina crude extract [ 11 ]; Amorphophallus paeoniifolius leaves extract [ 12 ]) or in mixtures (e.g., Sida acuta and monoethylene glycol [ 13 ]; methionine and cetylpyridinium bromide [ 14 ]) and the use of drugs as corrosion inhibitors [ 15 ]. Such inhibitors are mainly investigated with respect to their discovery and manufacturing process [ 16 ], the inhibitor properties [ 17 , 18 ], the inhibitor efficiency [ 19 , 20 ] and the environmental impact [ 21 ].…”

PickT: A Decision-Making Tool for the Optimal Pickling Process Operation

2023

This research approaches knowledge gaps related to the pickling process dynamic modelling (the lack of predictability and simplicity of existing models) and answers the practical need for a software tool to facilitate the optimum process operation (by delivering estimations of the optimum corrosion inhibitor addition, optimum pickling bath lifetime, corrosion rate dynamic evolution, and material mass loss). A decision-making tool, PickT, has been developed and verified with the help of measurements from two different pickling experiments, both involving steel in hydrochloric acid. The first round of experiments lasted 336 h (each pickling batch duration was 24 h) and Cetilpyridinium bromide (CPB) was the corrosion inhibitor in additions from 8% to 12%. The collected dataset served for the tool development and first verification. The second round of experiments lasted 10 h (each batch duration was 2 h) and involved metformin hydrochloride (MET) in additions between 3.3 g/L and 10 g/L. This dataset served to test the transferability of PickT to other operating conditions in terms of corrosion inhibitor type, additions, batch duration and pickling bath lifetime magnitude. In both cases PickT results are in accordance with experimental findings. The tool advantages consist of the straightforward applicability, the low amount of field data required for reliable forecasts and the accessibility for untrained professionals from the industry.

“…These biodegradable plant extracts are low-cost and environment-friendly, so the research on these green corrosion inhibitors is significant due to economic and environmental benefits. In the last few years, numerous extracts have been used from various biomass of plants (Ji et al 2015 ; M’hiri et al 2016 ; Prabakaran et al 2016 ; Aribo et al 2017 ; Ali Asaad et al 2018 ; Anuchi and Ngobiri 2018 ; Bhuvaneswari et al 2018 ; Verma et al 2018c ) as an efficient natural corrosion inhibitor. Some innovative and new approaches like oxidation/polymerization reactions were used to enhance the efficiency of the Nettle bio extract.…”

An eco-friendly approach to inhibit the corrosion of boiler quality (BQ) steel by onion waste in acidic media was investigated. The extract from onion peel was characterized using the conventional extraction method and was characterized using HPLC. The efficacy of the onion peel extract (OPE) as a green corrosion inhibitor was studied using the weight loss method and a variety of electrochemical techniques, including open-circuit potential (OCP), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS). The Tafel polarization revealed that at 200 mg L −1 of onion peel extract (OPE), corrosion current density was reduced maximum in both 1 (M) HCl and 0.5 (M) H 2 SO 4 media. From the electrochemical impedance spectroscopy studies, the maximum inhibition efficiencies of 91.30% and 90.71% were found at 200 mg L −1 in 1 (M) HCl and 0.5 (M) H 2 SO 4 , respectively. The Langmuir isotherm was determined to be the best-fitting model, and the thermodynamic parameter, such as free energy , was computed, which indicated the physisorption of OPE onto the BQ surface. In theoretical investigations, density functional theory DFT was used to determine the adsorption efficiency and reactive sites of the OPE molecule by exploring various quantum chemical parameters.

“…It has been observed that over 20% of the negative effects corrosion has on the metallic substrates can be counteracted using different inhibition methods [11]. Therefore, there are several researches concerning CI [12][13][14][15] from the perspectives of e ciency [16-18] and environmental impact [19][20][21]. Such studies may focus on cetylpyridinium bromide, C 21 H 38 BrN, (CPB), the CI used in the present research in a hydrochloric acid solution for the protection of carbon steel plates, as it is an effective corrosion inhibitor for copper and copper-iron alloys [22,23].…”

The knowledge gaps approached in this research are related to the dynamic modelling of the pickling process (the lack predictability and simplicity of the existing models) and to the process operation (its dependence on the initial conditions, such as the immersed surface, the immersed mass, and the corrosion inhibitor concentration). Original contributions regarding the identification of the optimum corrosion inhibitor concentration, the forecast of the corrosion rate and the appropriate timing for the acidic bath change, are offered with the help of a decision-making tool (PickT), developed, and verified with the help of measurements. Experiments consist in steel pickling (during 336h) in hydrochloric acid of industrial making (H2O:HCl, 1:1) with five different volumetric Cetilpyridinium bromide (CPB) as corrosion inhibitor. PickT has reliably and easy forecasted the corrosion rates, facilitating the estimation of the appropriate timing for the acidic bath change (250h) and of the optimum concentration of inhibitor of 12%. Results are in accordance with experimental findings. The tool advantages consist of the straightforward applicability, the low inputs requirements to make reliable forecasts and the accessibility for untrained professionals from the industry. From an industrial point of view, it supports decision to optimize the pickling process efficiency and facilitate cost savings: when to change the pickling solution, which is the optimum corrosion inhibitor addition, how much metal surface can be pickled using the same solution.
