Corrosion due to carbon dioxide (CO2) has a major impact on the oil and gas industry by severely affecting production and process facilities. One of the most economic methods to prevent the corrosion of piping and plants is the application of corrosion inhibitors. The presences of corrosion product such as iron carbonate (FeCO3) film may affect to the performance of corrosion inhibitor. In addition to that, fluid flow effect in pipeline may also influence the performance of corrosion inhibitor. Thus, the present work is conducted to study the effect of FeCO3 film to the performance of imidazoline based corrosion inhibitor under fluid flow effect. The experiments were done in glass cells at 80°C. The hydrodynamic condition experiment was simulated using rotating cylinder electrode (RCE). Corrosion inhibitor was added at two different concentrations in the iron carbonate film formation. A corrosion rates were measured by linear polarization resistance (LPR) method. The film was later analyzed using scanning electron microscopy (SEM). It was found that a better corrosion protection is still offered by corrosion inhibitor even with presence of FeCO3 film. A synergistic effect is offered by these two films of corrosion inhibitor and FeCO in reducing corrosion rate.

Hydrogen sulfide and alkanethiols are toxic compounds containing in the production of wells in many oil and gas condensate fields. Because the policy of hydrocarbon processing enterprises aimed at the development of new fundamental research, processes and technologies in order to find rational use of raw materials, the conversion of hydrogen sulfide and alkanethiols into valuable compounds is one of the strategic goals of the oil and gas industry. The methods of "green" chemistry are perspective processes for converting hydrogen sulfide and alkantiols into valuable organic compounds, which allow working in environmentally friendly conditions with minimal energy and resource costs. The reactions of direct nucleophilic substitution of butanol-2, pentanol-1 and hexanol-1 to HS- and RS- group by single-electron reduction of hydrogen sulfide and alkanthiol in acetonitrile and ionic liquid at room temperature and atmospheric pressure with a single by-product - H2O were described. The possibility of conducting an experiment without electrolyte due to the intrinsic electrical conductivity of the ionic liquid allows not only lowering the consumption of reagents, but also facilitating the isolation of the target product. Due to the structuring and the matrix effect in ionic liquids, the duration of electrolysis in the reactions under consideration is 2-3 times less than in the case of aprotic solvents.
