Abstract
Carbon dioxide (CO2) capture and storage (CCS) and most CO2 capture and utilization (CCU) routes require concentrated CO2 streams for efficient compression, pipeline transport, injection, or chemic...
Highlights
Finding the optimal stage number for such a multistage fluidized bed temperature swing adsorption (TSA) process is a compromise between equipment costs and operating costs
The chosen process concept and solid sorbent were experimentally proven at bench scale before
We show that a CO2 capture rate of 50% would be preferable for CO2 capture from atmospheric air (Case 1), and a stage configuration of 2 × 10 (2 stages in the adsorber, 10 in the desorber) is most suitable for this case
Summary
Among other measures regarding restoration of natural carbon stocks and in the field of non-CO2 greenhouse gases, the drastic reduction of CO2 emissions from fossil sources. Because the worldwide energy system depends roughly 80% on fossil fuels and a switch to renewables will take time, a prominently discussed approach is the capture of CO2 from anthropogenic sources followed by long-term storage of the captured CO2 in suitable geologic formations (carbon capture and storage, CCS). An alternative to CO2 storage is the utilization of the captured CO2 as a resource for chemical syntheses or for other purposes (carbon capture and utilization, CCU). In most CCU cases, the CO2 is required in concentrated form. Capture and concentration account for roughly 75% of the total energy demand in CCS value chains.[1]
