Bis-Mannich bases as effective corrosion inhibitors for N80 steel in 15% HCl medium

Corrosion inhibition of N80 steel in 15% HCl was investigated in the absence and presence of different concentrations of some thiosemicarbazide derivatives (Mannich baseI, Mannich baseII) by weight loss, potentiodynamic polarization techniques. The adsorption of Mannich bases obeyed Langmuir adsorption isotherm. Both thermodynamic and activation parameters were calculated and discussed. The absorption process of Mannich base corrosion inhibitors on the surface of N80 steel is spontaneous, endothermic and entropy increase process. Polarization curves indicated that the inhibitor of Mannich bases are the mixed corrosion-controlling one which inhibited anodie corrosion. The results obtained from weight loss, Potentiodynamic polarization are in good agreement.

Inhibition Property

The corrosion inhibition behaviour of four selected Mannich bases compounds,namely 3-((N-methyl,N-phenyl)-methyl)2,4-Acetylacetone(MPMAA),3-((N-phenyl)-methyl) 2,4-Acetylacetone (PMAA),3-((N, N-diethyl)-methyl) 2, 4-Acetylacetone(DMAA) and 3-((N, N-methyl)-methyl) 2, 4-Acetylacetone (MMAA) as corrosion inhibitors for mild steel in 1M HCl solutions. Tafel polarization methods were performed to determine the corrosion parameters and inhibition efﬁciencies. Experimental results showed that PMAA is an excellent inhibitor for mild steel corrosion in 1M HCl solutions; showing a maximum efficiency 92.3% at concentration of 40mg/L. Polarization studies showed that the Mannich bases compounds can be regarded as mixed-type inhibitors and the inhibition efﬁciency of the four inhibitors followed the order PMAA > MPMAA > DMAA > MMAA. Then scanning electron microscope (SEM)techniques were also employed to examine the mechanism of corrosion inhibition property.

Purpose This paper aims to introduce a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor. Design/methodology/approach This paper introduced a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor. Findings The experimental results indicated that the influence of pre-corrosion status on corrosion rate and effectiveness of corrosion inhibitor are significant. The corrosion inhibitors in both injection stage inhibited the corrosion process by preventing the contact of corrosive medium and steel surface through formation of a protective film on the surface of N80 steel. The corrosion rate of polymer degradant can be reduced to 0.63 g/m 2 h through subsection injection with different inhibitor. Originality/value This result will increase the production of polymer injection plugging wells through expanding the application of acidic-oxidized polymer degradant.
