Abstract

Membrane-based electrochemical sensors (MBES) were evaluated inside a multiphase liquid water and natural gas flow facility to monitor internal corrosion and conductivity at 6,900 kPa (1,000 psi); flow rates of 4.6, 9.1, and 18.3 m/s; and temperatures of 21, 29, and 35 °C (70, 84, and 95 °F). All sensors followed similar trends in open circuit potential, corrosion rate, and conductivity over time. Neither flow rate, temperature, nor build-up of metal-based solids on the sensor surfaces impacted the quality of the electrochemical measurements. The field-test results confirm that the MBES are suitable for monitoring internal corrosion of operational natural gas pipelines.
