Abstract
The paper presents the results of research on the selection of the optimal composition of an imidazoline-based corrosion inhibitor with ketone or ketoxime for an acidic environment. Studies have been conducted on the effect of temperature on the quality of inhibition. The characteristics of inhibition at different exposure times (up to 720 hours) have been studied. The effect of the fluid flow regime on the quality of inhibition by ketones or ketoximes has been established. It is shown that for any of the cases, changing the mode from laminar to turbulent reduces the degree of protection from 1,5 to 2,2 times.
Materials and methods
