Efficiency of Using Organic Inhibitors for Corrosion Protection of Oil and Gas Industry Equipment

This article investigates corrosion protection methods for technological equipment in the oil and gas industry and primary oil refining units. The classification of liquid-phase and volatile inhibitors depending on environmental aggressiveness, along with their adsorption and action mechanisms on metal surfaces, is described. A comparative analysis of the protective properties of organic compounds containing heteroatoms (N, S, P), specifically amide- and imidazoline-based inhibitors, was conducted. Using the example of the ELOU-AT-6 unit at the "KINEF" refinery, the technological scheme for feeding inhibitors and neutralizers, as well as the optimal dosing regime, is outlined.
