ABSTRACTThe climate change the planet experiencing in recent years is due to the escalating levels of carbon emissions coming predominantly from our continued use of fossil fuels. In the light of increasing fears about climate change Carbon Capture and Storage (CCS) has assumed growing importance as it provides a bridging technology which balances the increasing demands for energy and the requirements to reduce emission. Extensive industrial experience is already available in CO2 pipelines for enhanced oil recovery (EOR) operations but further experience is needed for transporting injecting and storing of CO2 into the geological formations. Carbon steels are candidate materials for construction of CCS network. This paper focuses on the evaluation of carbon steel material (API 5LX60) by studying the corrosion performance in deaerated NaCl solutions in simulated flow condition using Rotating Cage under CO2 environment and at atmospheric pressure. The corrosion rate of samples was determined by mass loss measurements. The effect of NaCl concentration and period of rotation on the corrosion rates has also been studied by conducting typical laboratory tests continuously for 24 48 72 and 96 hours at 1515 and 30% NaCl solutions under flow conditions in CO2 environment. The surface morphology and the composition of the corrosion product layers of the metal samples subjected to mass loss studies were analyzed by using surface analytical techniques (SEM and EDS).Keywords- CCS network CO2 sequestration Carbon steel corrosion CO2 Corrosion Rotating Cage.
