51317-9340-Investigation of Under-deposit corrosion on X-60 using Multielcetrode System

The effect of the deposition of sand and field sludge on the corrosion mechanism of carbon steel in sour environments. Under-deposit corrosion (UDC) of carbon steel was studied underneath the sand deposit and the field sludge in a simulated sour environment

This paper presents the effect of the deposition of sand and actual field sludge on the corrosion mechanism of carbon steel in sour environments. Under-deposit corrosion (UDC) of carbon steel was studied underneath the sand deposit and the field collected sludge deposit in a simulated sour environment by means of linear polarization resistance (LPR), coupled multi-electrode array system (CMAS) and weight-loss coupons.

The results showed that when actual field sludge was deposited on the carbon steel surface, significant general and localized corrosion rates were observed. While in the sand deposit test, the general and localized corrosion rates were found to be very low, even lower than the no deposit test. No UDC was observed on coupons tested under the sand deposit, meaning that sand inhibits corrosion of carbon steel in a sour environment.

Key words: conference papers, 2017 conference papers, Coupled multi-electrode array system, under-deposit corrosion, linear polarization resistance and sour environments.
