Abstract

The use of antifoaming and corrosion inhibitor agents to prevent foaming and corrosion, respectively, is widely used in the carbon dioxide (CO₂) absorption process using alkanolamines. However, the effect of these agents on the capacity of the alkanolamine solutions to absorb CO₂ is unknown. We present a study on the phase equilibria and solubility of CO₂ in mixtures of aqueous methyldiethanolamine (MDEA) solutions with and without these additives and show how the liquid phase properties and CO₂ loading capacity is affected.
