使用吸湿性离子液体[EMIM][MeSO3]进行的连续气体干燥实验表明，它可以成为工业气体干燥过程中常用的吸收剂三甘醇（TEG）的非常有前途的替代干燥剂。 HTU/NTU 模型结合 Onda 等人的相关性。传质系数可应用于[EMIM][MeSO3]吸收过程的设计。这种离子液体 (IL) 的主要优点是，由于蒸气压极低并且可以用空气再生，因此使用 [EMIM][MeSO3] 可以避免与吸收剂 TEG 再生相关的众所周知的问题。 IL 系统的干燥能力大约是 TEG 的两倍。因此，可以采用与工业吸附设备相当的简单设备设计。
Continuous gas drying experiments with the hygroscopic ionic liquid [EMIM][MeSO3] show that it can be a very promising alternative drying agent to the absorbent triethylene glycol (TEG) commonly used in industrial gas drying processes. The HTU/NTU model in combination with the correlations of Onda et al. for mass transfer coefficients can be applied for the design of an absorption process with [EMIM][MeSO3]. The major advantage of this ionic liquid (IL) is that well‐known problems associated with the regeneration of the absorbent TEG can be avoided using [EMIM][MeSO3] due to extremely low vapor pressure and possible regeneration with air. The drying capacity of the IL system is about two times higher compared to TEG. Hence, a simple plant design comparable to that of industrial adsorption plants might be applied.
