Effect of Additives on the CO₂ Absorption in Aqueous MDEA Solutions

Abstract

The use of antifoaming and corrosion inhibitor agents to prevent foaming and corrosion, respectively, is widely used in the carbon dioxide (CO 2 ) absorption process using alkanolamines. However, the effect of these agents on the capacity of the alkanolamine solutions to absorb CO 2 is unknown. We present a study on the phase equilibria and solubility of CO 2 in mixtures of aqueous methyldiethanolamine (MDEA) solutions with and without these additives and show how the liquid phase properties and CO 2 loading capacity is affected.

Effect of TBAB and SDS surfactants on the interfacial tension of CO2 Hydrate in water

“…guest molecules are encapsulated in the cavities formed by water molecules which are connecting together by hydrogen bonding and gas hydrates are formed [2][3][4][5][6]. Since the nucleation of hydrate is in part an interfacial phenomenon, interfacial properties such as the interfacial tension between gas and water may have a great influence upon the hydrate formation rate [7][8][9][10][11][12][13]. Some surfactants are used to slow or prevent hydrate formation in oilfields.…”

Thermal and mechanical properties of liquid‐like trisilanol isobutyl‐polyhedral oligomeric silsesquioxanes (POSS) derivative/epoxy nanocomposites

“…By modifying the surface of nanoparticles with some liner polymers, they can be prepared into liquid‐like derivatives. The derivatives are liquid‐like without any solvent near room temperature and can achieve single dispersion of nanoparticles . Because of the great interaction between polymer chains on the surface of liquid‐like derivatives and the polymer matrices, the liquid‐like derivatives can usually get excellent dispersion in epoxy and improve the mechanical properties of the epoxy obviously .…”
