Annotation: The effectiveness of corrosion inhibitor PKA-1 based on polyethene polyamine and crotonaldehyde on St2 steel in systems containing H2S and water-salt phases was studied. This corrosion inhibitor was tested at different concentrations (200 mg/l, 400 mg/l, 600 mg/l, 800 mg/l and 1 g/l). PKA-1 brand corrosion at a concentration of 600mg/l, the level of protection against corrosion was 93.56%. SEM and elemental analysis methods of the obtained results were also studied.

Keywords: polyethylenepolyamine, crotonaldehyde, corrosion inhibitor, hydrogen sulfide, gravimetric method, SEM, elemental analysis.
