Effect of Salt Concentration on CO2 Uniform Corrosion

Available for download

Hydrocarbon extracted from oil and gas wells is typically accompanied by the production of brines. Salt concentration or salinity is a general characteristic of brines that can vary from 1000 to 400000 mg/l. The effect of salt concentration on uniform CO2 corrosion has been studied in the past however most of these studies have been performed at low salt concentrations usually between 1 to 3 wt.% NaCl. Moreover no true mechanistic study of corrosion has been done to cover the higher ranges of salt concentration. In this study CO2 uniform corrosion of an API X65 carbon steel was studied by weight loss (WL) linear polarization resistance (LPR) and potentiodynamic polarization methods in a range of NaCl concentration from 0 to 20 wt.%. The WL and LPR results both showed a maximum in the corrosion rate at 1 wt.% NaCl. The polarization curves showed that the key change due to higher salt concentrations was in the cathodic limiting current.Keywords: CO2 uniform corrosion carbon steel high salt concentration weight loss linear polarization resistance potentiodynamic polarization

The NORSOK M-506 is an empirical model based on experiments undertaken in a single phase water flow loop. The data is from experiments with low content of iron ions in the water phase, and the model is thus regarded to give a fair representation of the maximum corrosion rate in a CO2 corrosion controlled system.

The literature has been reviewed with respect to information gained in the recent 20 years on CO2 corrosion of materials used in the oil and gas industry. The paper discusses the effect of materials related, medium-related and interface-related parameters on general (uniform) and localized corrosion.  Part II

The corrosion mechanism of X65 carbon steel was evaluated in water environment by increasing CO2 partial pressure from 1 bar at 24 °C to 110 bar at 40 °C, reaching conditions that include water saturated with supercritical CO2.
