Inhibitory and bactericidal action of the biocorrosion agents «INCORGAS» and «AMDOR»

摘要: Abstract Inhibiting action of A, B and M-X compositions against hydrosulfide corrosion carbon steel, hydrogen diffusion through the steel membrane has been studied along with their bactericidal effect respect to sulfate-reducing bacteria Desulfomicrobium type. Bactericidal properties have in Postgate medium. Corrosion tests made NACE medium saturated by sulfide dioxide separately together methods gravimetrical measurements linear polarization resistance (LRP). Potentiodynamic electrochemical method used. Steel protection is determined inhibited solutions combined products film inhibitor. Presence increases flux 2–3 times essentially stimulates inhibitors. The inhibiting decrease quantity (SRB) 95–98%. obtained results testify about predominately bacteriostatic compositions, which influence on enzymatic systems SRB cells responsible directly for sulfate reduction because substantially decreasing biogenic concentration system.
