Abstract

Significance: Ionic liquids (ILs) are employed for air‐drying for the first time. The experimental gas–liquid equilibrium (EQ) of N2 /O2 + [EMIM][BF4 ] and N2 /O2 + [EMIM][BF4 ] + H2 O systems under a broad temperature range are measured. The new modified UNIFAC‐Lei model is successfully extended to predict the N2 /O2 ‐IL‐H2 O system based on extensive phase EQ data. The air‐drying experiment using [EMIM][BF4 ] as an absorbent is conducted, confirming that this new technology is effective and efficient. © 2018 American Institute of Chemical Engineers AIChE J, 65: 479–482, 2019
