Inhibition of Corrosion and Hydrogenation of Carbon Steel with a Number of Inhibitors in Weakly Acid Media Containing H_2S and CO_2

摘要

The inhibitive power of AMDOR IK-7 formulation,homologous mixture of alkyl ammonium acetates C_(10)-C_(14)in a specific solvent,and PKU-6 toward corrosion of St.3 steel in weakly acid media containing 5.8 g l~(-1)NaCl,H_2S,and CO_2 was studied.The influence exerted by the inhibitors on the kinetics of partial electrode reactions and on the hydrogenation of steel was examined.Impedance spectra were recorded and analyzed.
