Abstract in another language

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.
