Important Activity

Corrosion is a hazardous phenomenon having a devastating impact on technological and industrial applications, particularly in the oil and gas industries. Therefore, controlling the corrosion of metals is an important activity of technical, economical, environmental, and aesthetical importance in order to save huge expenses in materials, equipment, and structure. The use of corrosion inhibitors is one of the best options for controlling the metallic corrosion in various corrosive media. Numerous problems aroused with the use of inorganic and small molecule organic corrosion inhibitors, and the use of polymeric corrosion inhibitors came into limelight. This review article provides an overview of the recent development of different classes of corrosion inhibitors with special emphasis on different functional motifs of natural, synthetically modified natural, and synthetic polymeric materials.

Metallic Corrosion

The use of corrosion inhibitors is the one the most economical and practical means of controlling metallic corrosion in different corrosive media. Interest on the use of eco-friendly organic compounds as corrosion inhibitors has extended to the use of polymers to inhibit metallic corrosion. The use of polymers as corrosion inhibitors has attracted attention and has gained wide acceptance in recent times. This has been attributed to a number of factors namely: (i) they are low cost and stable to metallic materials in acid media, (ii) they possess multiple adsorption sites, (iii) through their functional groups, they form complexes with metal ions and on the metal surface these complexes occupy a large area, thereby blanketing the surface and protecting the metal from corrosive agents present in the solution. A number of synthetic and natural polymers as metallic corrosion inhibitors have been investigated and reported. As an update to previous review work on the use of polymers as corrosion inhibitors, the present review presents most of the contributions made to the literature on the use of polymers as corrosion inhibitors of diverse metals in different corrosive media in the last four (2010-2013) years.

Corrosion inhibitors are widely used for protection of technological equipment and pipelines in the oil and gas industry. However, the operation of these objects under the influence of corrosive media of high aggressiveness and the widespread use of new constructive materials call for development of increasingly effective reagents. In this regard, the creation of competitive inhibitors that provide a high protective effect is a very urgent task, the solution of which is of significant importance for the country's economy. The paper considers the synthesis of new corrosion inhibitors based on quaternary ammonium compounds and the study of the effectiveness of their practical application in the implementation of anticorrosion protection of oilfield equipment made of carbon steel 20 and low-alloy steel. It has been established that as a result of the synthesis based on triethanolamine and orthophosphoric acid, triethylamine and 1,3-dichloropropene, and also condensation of polyethylene polyamine with 1,2-dichrolylethane, it is possible to obtain high-molecular compounds that effectively inhibit corrosion processes in oil and gas equipment proceeding along the electrochemical mechanism. To study the protective properties of the developed corrosion inhibitors, gravimetric analysis was used. It has been established that some nitrogen- and phosphorus-containing quaternary compounds under conditions similar to those in oil fields exhibit rather high inhibitory protection effects, and therefore can be recommended as a basis for the creation of new inhibitors of corrosion of tubular steels in mineralized reservoir environments. It is shown that the maximum inhibitory protection effects of the developed inhibitors are achieved at their moderate concentrations in the mineralized formation water, and with an increase in the concentration, the corrosion rate of the tested tubular steels is substantially reduced.Forcitation:Khaydarova G.R., Tyusenkov F.S., Bugai D.E., Raskildina G.Z., Islamutdinova A.A., Sidorov G.M.

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.

Carbon Steel 1018 is a low carbon steel having a carbon content (C) of 0.14-0.20% (<0.30% C). Low carbon steel is commercially known as mild steel. Corrosion is one way to prevent corrosion caused by the environment. Corrosion inhibitor are taken between the Crude Corrosion Inhibitor and Gas Corrosion inhibitor on Carbon Steel 1018 using the polarization method. Corrosion inhibitors work by making passive layers in the form of thin films or films on the surface of the material used as a barrier between metals and corrosive media. The analysis method used is polarization. Inhibition Efficiency Results obtained for Gas Corrosion Inhibitors (1A) at 10 ppm 96.86%, 20 ppm 59.74%, 30 ppm 74.48%. The Crude Corrosion Inhibitor (2A) results obtained inhibition efficiency for 10 ppm 99.57%, 20 ppm 77.69%, and 30 ppm 12.63%. The optimum value for the Gas Corrosion Inhibitor and Crude Corrosion Inhibitor is at 10 ppm at 96.86% and 99.57%. Keywords: carbon steel,crude corrosion inhibitor, corrosion , gas corrosion inhibitor, inhibitor

Strong Adhesion

This review article aims to summarize the potential of using renewable natural resources, such as lignin and tannin, in the preparation of NIPUs for wood adhesives. Polyurethanes (PUs) are extremely versatile polymeric materials, which have been widely used in numerous applications, e.g., packaging, footwear, construction, the automotive industry, the lighting industry, insulation panels, bedding, furniture, metallurgy, sealants, coatings, foams, and wood adhesives. The isocyanate-based PUs exhibit strong adhesion properties, excellent flexibility, and durability, but they lack renewability. Therefore, this study focused on the development of non-isocyanate polyurethane lignin and tannin resins for wood adhesives. PUs are commercially synthesized using polyols and polyisocyanates. Isocyanates are toxic, costly, and not renewable; thus, a search of suitable alternatives in the synthesis of polyurethane resins is needed. The reaction with diamine compounds could result in NIPUs based on lignin and tannin. The research on bio-based components for PU synthesis confirmed that they have good characteristics as an alternative for the petroleum-based adhesives. The advantages of improved strength, low curing temperatures, shorter pressing times, and isocyanate-free properties were demonstrated by lignin- and tannin-based NIPUs. The elimination of isocyanate, associated with environmental and human health hazards, NIPU synthesis, and its properties and applications, including wood adhesives, are reported comprehensively in this paper. The future perspectives of NIPUs’ production and application were also outlined.
