| Summary: | Corrosion in multiphase systems comes from the electrochemical interaction of the corrosive species (CO2, H2S, oil (oil phase) etc.), dissolved in aqueous environments one with the steel, taking to the metallic oxidation and the subsequent metal loss, this situation is significantly increased by the effects related with the flow in multiphase systems. The CO2 corrosion rate has been widely studied, but few works they have addressed the effects of the CO2 with small quantities of H2S.This study evaluated the corrosion rate in a multiphase system consisting of a brine saturated with CO2, H2S and mineral oil in contact with a carbon steel AISI-SAE 1020 to different conditions of temperature and velocity, using a simulator of flow rate Loop. We determined the effects of flow rate, temperature and the oil / water by electrochemical techniques Tafel and electrochemical impedance spectroscopy. |
