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.
