Abstract
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.
