Creating Custom Amine Fluids for Carbon Capture and Gas Treating

We have designed this new training exercise for chemical engineers specializing in gas treating, including those working in carbon capture and storage (CCS) and H2S removal. This exercise uses the Electrolyte NRTL (eNRTL) method to create a custom amine fluid for modeling reactive absorption systems. The eNRTL method extends the conventional Non-Random Two-Liquid (NRTL) framework by incorporating electrolyte-electrolyte and electrolyte-molecule interactions, making it suitable for systems involving CO2, HCO3-, CO32-, protonated amine, and carbamate ions. The objective of this exercise is to build a custom aqueous amine fluid, such as monoethanolamine (MEA), that accurately represents phase behavior, chemical reactions, acid gas solubility, and heat of absorption. This custom fluid is then applied to vapor-liquid equilibrium (VLE) and heat of absorption simulations to compare the results with expected reference values.
