Inhibiting Corrosion in Transport Pipelines by VpCI Additives to Crude Oil

Typical patterns of corrosion and the corrosion growth obtained from the successive intelligent pig runs in ageing pipelines, made obvious that after decades of problem free operation, corrosion may become a serious threat. Application of corrosion inhibitors is a mean of ensuring continuation of pipeline operation without costly repairs, leaks and release of hazardous materials into the environment. This paper investigates protective ability of VCI 629 BIO and VCI 637 HF on carbon steel, in stagnant and flowing electrolytes, in order to take into account the unfavourable conditions at critical points of the pipeline (low points, dead legs) and the intermittent flow regime. Laboratory measurements were done in crude oil and in 3.5% NaCl of pH 7.5. Corrosion coupons and the LPR probe were used to quantify the corrosion rate in the absence and the presence of the inhibitors. FTIR results have shown that the inhibitor adsorbs onto the rusted surface and retains in the rust layer even when the LPR probe transferred back to inhibitor free electrolyte. The role of inhibitors was discussed with respect to the corrosion conditions prevailing at pipeline critical spots, deduced from H2S measurements in transported crude oils, SEM/EDX, FTIR, XRD, Cl- and SO42- analyses of samples (oil, sludge and paraffin) collected from cleaning pig exits and from a dead leg at which perforation of pipe wall has occurred due to corrosion.
