Do you need deep removal of CO2 and H2S?
You can, using Shell’s ADIP-X technology. The ADIP-X technology was introduced in 2000 by Shell for cost-effective removal of CO2, H2S and COS. The addition of piperazine to methyl diethanolamine (MDEA) accelerates the reaction kinetics. Our current reference sites remove CO2 down to <50 ppmv from approximately 20 vol% CO2 in the feed, thereby meeting the low level required in LNG plants
- <50 ppmv CO2 removal;
- Faster CO2 and COS removal through enhanced reaction kinetics;
- Higher loading capacity, which reduces the solvent circulation rate by 20–30% and enables the use of smaller equipment;
- Reduced steam requirements because of its lower solvent circulation rate and heat of reaction;
- Very low hydrocarbon co-absorption; and
- Reduced solvent degradation, with no reclamation required.
- The technology could come with a range of service offerings such as proactive monitoring, training and troubleshooting.
- A comprehensive solvent monitoring programme conducted by a Shell in-house laboratory is available: leverage operational experience to maintain solvent quality.
ADIP technology has a long history in Shell. First developed in the 1950s and with over 500 Shell operating facilities and licensees, it is our most referenced technology to date. ADIP technology has established a track record of high levels of performance and reliability.
