CO2 Summit III: Pathways to Carbon Capture, Utilization, and Storage Deployment
For the past eight years, Membrane Technology and Research, Inc. (MTR) sponsored by the U.S. Department of Energy, has been developing membrane technology to capture CO2 from power plant flue gas. A 20 ton/day test system has been built and operated at two field sites. The technology is moving to the 200 ton/day (10 MWe) demonstration scale. A block diagram of the MTR process is shown in Figure 1. One innovation of this process is the use of a two-step membrane design where the second step uses a membrane operating with air sweep to selectively recycle CO2 to the boiler. …

CO2 Summit III: Pathways to Carbon Capture, Utilization, and Storage Deployment
Adsorption processes for CO2 capture have gained significant attention in the last decade with hundreds of reports on new adsorbents and processes for capture and removal of carbon dioxide from a range of gas streams. To date, the only commercial examples are removal of trace carbon dioxide in gas streams such as LNG and ASU upstream molecular sieve units. There are no commercial examples of the use of adsorbents to capture carbon dioxide by adsorption processes and deliver a stream of high purity carbon dioxide for sequestration or further processing. In this study, we present the range of processing options …
