“…Gibbs energy is a quantity whose change in the course of a chemical reaction is equal to a change in the internal energy of the system. It is believed that high negative values of the Gibbs energy indicate strong adsorption of the inhibitor on the steel surface [47], while the values of ∆G up to −20 kJ/mol refer to the process of physical adsorption, values of about −40 kJ/mol or more-to chemisorption due to shared use or transfer of electrons from a molecule to a metal surface, and values in the range from −20 to −40 kJ/mol correspond to a joint mechanism consisted of physical and chemical adsorption [15].…”

Acid treatments are one of the methods for intensifying oil and gas production. Corrosion is a significant factor affecting the performance of oilfield equipment. There are many different methods of preventing corrosion, but corrosion inhibitors are most commonly used in industry. The protective effect of the inhibitor is directly determined by the effective adsorption of surfactants on the metal surface. For an indirect assessment of the adsorption of the inhibitor, a comprehensive research method is proposed based on the determination of the interfacial tension of acid compositions and steel plates’ contact angle of wetting after corrosion tests. It was found that in hydrochloric acid the adsorption of the inhibitor IC-1 reaches a maximum after 6 h, an increase in the acid concentration in the range of 5–15% wt. has a negative effect on the activity of the inhibitor. For sulfamic acid, the maximum adsorption of the IC-2 inhibitor is observed after 24 h, an increase in acid concentration has a positive effect on surfactants.

Imidazolium bearing ionic liquids (ILs), 3-hexadecyl-1-methyl-1H-imidazol-3-ium bromide [C 16 M 1 Im] [Br] and 3hexadecyl-1,2-dimethyl-1H-imidazol-3-ium bromide [C 16 M 2 Im] [Br] have been synthesized. These compounds were evaluated for corrosion resistance of mild steel in 1M HCl solution by gravimetric and electrochemical studies. The results were noticed that the inhibition efficiency, has enhanced due to a rise in the concentration of inhibitor. Further, it is observed that [C 16 M 2 Im] [Br] inhibition efficiency better than [C 16 M 1 Im] [Br] due to the increased alkyl substituents. Polarization study reveals that the used inhibitors behave as a mixed type, but predominantly exhibited the anodic inhibitive effect. The inhibitors adsorbed on the metal surface obeys Langmuir adsorption isotherm. Surface topography examined using an Atomic Force Microscope (AFM) and a Scanning Electron Microscope (SEM) with EDAX analyses. The formation of the Fe-inhibitor complex on mild steel surface has been confirmed by UV-Visible spectroscopy.

in the process of high sulfur coal mining, with coal gas outburst, a large amount of highly toxic flammable hydrogen sulfide (H 2 S) gas is produced which threats miner's health and pollutes the environment seriously. it is shown that adding an oxidizing agent in alkaline absorption liquid can obviously increase the removal rate of h 2 S in mine air in the experiment results, and there's no the hydrogen sulfide gas evolution after oscillation of the absorbing tail liquid, the removal efficiency is very remarkable. it is also shown that surfactant can reduce the surface tension of the absorption liquid in the research, accelerate the process of mass transfer between gas-liquid two phases, and improve the absorption efficiency.
