In order to reduce atmospheric emission of CO2 after being captured by acid gas removal technologies, CO2 can be re-injected for enhanced oil recovery or permanently stored in suitable underground reservoirs. For these applications it is required to compress CO2 to very high pressures.
Before CO2 is transported to the final destinations it needs to be dried in order to protect pipelines and other equipment from liquid water and corrosion. Since CO2 and water form carbonic acid, Sorbead adsorbents are particularly suited due to their high acid resistance. A most energy efficient and reliable drying process is designed by employing Sorbead Dehy technology (see also page 10).
