CO₂ Gas Drying

The dehydration of CO₂ streams presents specificities such as corrosiveness, acid gases co-absorption and TEG recovery. Consequently, for decades, it has been seen as a challenge for the operators. This stands true in various industries and particularly in the oil&gas sector, whether on highly sour natural gases or on pure CO₂ streams for enhanced oil recovery (EOR) purpose.

CO₂ Gas Drying process has seen a renewed interest in the current context and development of the Carbon Capture and Storage (CCS) industry.

CO₂ Gas Drying

Axens Offer

Thanks to Axens’ long-standing experience in the field of gas dehydration, industrial references on CO₂ drying and ability to offer both TEG and Adsorbent solutions, Axens has an unique position on the market to provide clients with the most cost-effective and fit-on-purpose solutions.

TEG

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.
