Carbon capture, transport, and storage (CCS) technology enable the reduction of CO2 emissions, thereby limiting the global temperature rise. This technology, coupled with a comprehensive thermodynamic model and complete database of species for the capture and transport steps, is a prerequisite for effective process design, simulation, and prediction of safe operating windows. In the storage step, the chemistry between the flue gas constituents (e.g., CO2, N2, O2, NOx, SOx, CO, etc.) and traditional/transformational solvents (e.g., MEA, MDEA, AMP, PZ, ammonia, aqueous K2CO3, etc.) and their mixtures need to be well understood. Additionally, captured CO2 is never pure; when transporting the CO2, impurities including various NOx, SOx, H2S, O2, and H2O can react and form highly corrosive acids or elemental sulfur. Even in minute quantities, these can be extremely aggressive to carbon steel and can lead to catastrophic failure of pipelines or tanks. The Mixed-Solvent Electrolyte (MSE) thermodynamic framework from OLI Systems, Inc. coupled with OLI’s software tools - OLI Flowsheet: ESP V10 and OLI Studio: Corrosion Analyzer V10 - is well suited for simulating CCS, and can help you to choose the appropriate material for construction and accurately predict the formation of corrosive components and understand their safe limits, corrosion rates, and the conditions that can lead to failure.
