One of the serious troubles faced by the oil and gas industry is corrosion wear of equipment and pipelines. The major part of failures of the oilfield equipment and pipelines is the result of corrosion damage, so protection of equipment from corrosion is one of the most urgent scientific and technical issues. One of the most common ways to control corrosion is inhibitor protection. The paper presents the results of studies of corrosion inhibitors synthesized on the basis of polyethylene polyamines and three varieties of light tall oil in the presence of alcohol solvents using the stillage residue of butyl alcohols rectification. The optimal parameters of synthesis and the ratio of basic raw reactants and solvents have been determined. The inhibitory properties of the synthesized samples were evaluated by changes in the rate of corrosion and the value of their protective efficiency. It has been shown that the best of the synthesized samples is not inferior to the industrial reactant Sonkor 9601 in terms of the protective effectiveness, and in the area of low concentrations (up to 40 g/t) exceeds the basic inhibitor.

Sour Corrosion

Main problem: Presence of acidic chemicals such as carbon dioxide and hydrogen sulphide, composition of production fluids triggers corrosion. Corrosion in oil and gas industry leads to deterioration of equipment since most of equipment is made of metal alloys. Application of inhibitors is one of the corrosion mitigation methods that needs to be controlled because it is important to identify optimal concentration of the chemicals in production fluids.Residual chemical analysis plays an important rolein identifying the appropriate dosage of corrosion inhibitors and its correction. It is imperative to find the most optimal concentration of amines due to the fact that both overdose and underdose could lead to equipment deterioration. The chemical analysis is hindered by complexity of mixtures that are applied in petroleum industry. Purpose: The main purpose of this article is to find out the most effective method of residual chemical analysis for inhibitors used against sweet and sour corrosion by studying and analyzing corresponding literature review. The analysis should be carried out with robust, sensitive, and accurate instrumentation. Methods :Theoretical study of composition and mechanism of amines used in oil and gas industry as corrosion inhibitors and selection of appropriate instrumental analytical techniques for the residual analysis. Results and their importance: After careful studying and consideration of modern instrumental analytical techniques the most optimal and efficient method in terms of robustness, time saving and cost was selected. Ion chromatography is an adequate method to carry out residual chemical analysis for amines that are used as inhibitors in oil and gas industry to prevent sweet and sour corrosion.

Carbon Nanocomposite

Metal-carbon nanocomposites have been investigated as additives to enhance the protective effect of corrosion inhibitors. Two inhibitors were used as corrosion inhibitors. Inhibitor VNH-L-113 (1-morpholinomethylcyclohexylamine) belongs to Schiff bases, which are known as corrosion inhibitors in neutral and acidic media. Inhibitor SNPKh-1004 is often used in the practice of corrosion protection in the oil and gas industry. For research, an electrochemical method was applied using corrosion rate meters of the Monicor type. Neutral aqueous solution and water simulating the corrosive environment of oil fields were chosen as corrosive media. The result shows, that the copper-carbon nanocomposite enhances the protective effect of corrosion inhibitors of various chemical nature in various corrosive environments. The studies carried out make it possible to consider the use of metal-carbon nanocomposites as a promising direction for increasing the effectiveness of inhibitors in the oil and gas industry.
