CO2 SOLUBILITY IN AQUEOUS MONOETHANOLAMINE WITH 1-ETHYL-3-METHYLIMIDAZOLIUM TETRAFLUOROBORATE

Majid Majeed Akbar, Asim Hassan Rizvi

Abstract


Aqueous monoethanolamine (MEA) solution (15 wt%) was mixed with 5, 10, 15 wt% ionic liquid namely, 1-ethyl-3-methylimidazolium tetrafluoroborate ([emim][BF4]). CO2 solubility in aq. MEA and aq. MEA-IL mixtures was measured experimentally at T = 298.15 K and over a pressure range of 100 to 3000 kPa. The addition of IL in the aq. MEA solutions affected its solubility. The solubility of all the mixtures increased with increase in pressure.
