Tests and evaluation studies were conducted to select the best performance and treating rich carbon dioxide fluid composition associated with crude oil are produced. The experiments include standard electrical resistance probe for direct corrosion monitoring technique, and inspection by using an ultrasonic test to assess corrosion inhibitor. The improvement process for chemical treatments development requires an effective strategy. The effective process for field testing inhibitor required twenty-four days to determine inhibitor performance and verifying minimum effective concentration. The standard electrical resistance probe with changeable dosage test was utilized. Ultrasonic testing one of the most widely used non-intrusive techniques is applied to measure of localized corrosion. Measurement apparatuses are adequate systems for monitoring of treatment efficiency.

Response surface methodology was applied to predict the optimum control of mild steel corrosion in acid medium with bitter kola leaf extract as inhibitor. The experiment was carried out to investigate the mutual interactions between the considered independent variables and the expected responses. Thermometric, gravimetric, potentiodynamics polarization and electrochemical impedance spectroscopy were used in the corrosion inhibition study. As a supplementary technique, infrared spectroscopy was used to analyze the pure extract and corrosion products and it was observed that some peaks shifted while some disappeared. Inhibition efficiencies of 88.24 %, 86.81 %, 90 %, 89.5 % and 85.3 % were obtained from optimization, thermometric, gravimetric, potentiodynamics polarization and electrochemical impedance spectroscopic techniques, respectively. The bitter kola leaf extract behaved as a mixed-mode inhibitor. Application of response surface methodology in this study was found to be good in predicting the optimum range for controlling of metal corrosion thereby reducing the number of experimental runs.

“…Accordingly, a good understanding of corrosion behavior in such conditions is of great importance in the assessment of the corresponding risk factors [13,14]. In fact, choosing appropriate inhibitors depends on parameters such as the type of acid, the temperature and the velocity of the fluid flow [15].…”

The present work investigates the influence of temperature on C38 steel corrosion in a 1 M HCl medium with and without different concentrations of a hydro-alcoholic extract of used coffee grounds (HECG). The potentiodynamic polarization technique and the electrochemical impedance spectroscopy were performed in temperatures ranging from 293.15 to 323.15 K. It was observed that the inhibition efficiency decreased with increased temperature and inhibitor concentration. The HECG adsorption process on C38 steel surface was found to be spontaneous and obeyed to Langmuir isotherm at all studied temperatures. The associated thermodynamic parameters of adsorption led to suggest the occurrence of physical adsorption of the HECG compounds on the C38 steel surface.
