Review on Corrosion Inhibitors for Oil and Gas Corrosion Issues

Abstract

The pipeline system in the oil and gas industry is the heart for transportation of crude and refined petroleum. Nevertheless, continuous exposure of the pipeline surfaces to impurities and sources of corrosion such as sulfur and chromate is totally unavoidable. Vast employment of commercial corrosion inhibitors to minimize the corrosion is being restrained due to toxicity towards the environment. The emergence of “green” chemistry has led to the use of plant extracts and fruit wastes which have proven to be good corrosion inhibitors. This paper aims to provide insight into carrying out further investigation under this research theme for accurate inhibition efficiency measurement.

Water-Induced Corrosion Damage of Carbon Steel in Sulfolane

“…- Corrosion of carbon steel used in the petroleum industry for pipelines or tanks is mainly caused by the presence of water, corrosive gases (H 2 S, CO 2 and O 2 ), chlorides and microorganisms. The most common form of corrosion occurs when carbon steel comes in contact with an aqueous solution, for instance, when CO 2 is dissolved in water, corrosive carbonic acid is formed [43][44][45][46][47][48][49]. Sulfolane in the presence of water and air also forms an aqueous solution of sulphurous acid [24][25][26].…”

The inhibition performance of a novel benzenesulfonamide-based benzoxazine compound in the corrosion of X60 carbon steel in an acidizing environment

“…The annual cost of mitigating corrosion in the industrialized world's according to, 8 is about £1.3 billion, and this estimated amount represents nearly 3-4% of their GDP per annum. 9,10 Corrosion has been controlled by some methods that include coating the surfaces of the corrosive materials with metals and organic polymers, [11][12][13][14][15][16] the use of inorganic and organic compounds as corrosion inhibitors, and cathodic protection. 17 In the oil wells, the use of corrosion inhibitors has proven to be easily practicable, efficient, and nancially more economical.…”

“…They also have more possibilities of losing grip at high acid concentrations beyond 17% compared to the organic inhibitors. 9 Environmental concerns are associated with such inhibitors obtained from arsenic salts that tend to release toxic arsine gas. 19 The organic inhibitors with hetero-atoms, show excellent affinity to the surface of the metallic substrates, due to the strong interaction between the pi-electrons of these atoms, and the empty d-orbitals of the transition metal (Fe atoms).…”

Binary Inhibitory Anti-Rust Paint

“…The most advanced means of enhancing anticorrosive protection are atmospheric corrosion inhibitors [4,5,6] This are poorly soluble corrosion inhibitors are introduced into paint primers using various technologies, including microcapsulation [7,8]. The disadvantages of this technical solution are insufficient protection efficiency due to weak passivizing properties.…”
