Water absorption with TriEthylene Glycol (TEG) is a highly flexible, easily operable and cost-effective technology for the reliable dehydration of various types of gases. This process has already been implemented and is industrially proven on CO2 dehydration applications even in the presence of other acid gases such as H2S.
As compared to field proven TEG units on natural gases, TEG units on CO2 dehydration applications have to factor in particular characteristics such as corrosiveness, acid gases co-absorption and TEG recovery.
Axens know-how in the domain of CO2-H2O-TEG thermodynamics, metallurgy selection, process design and modularization expertise ensure our clients to obtain the best-in-class TEG unit for their CO2 drying applications.
