The Direct Air Capture unit (DAC) is runs a process of vacuum – temperature swing adsorption. The process contains three phases:
- Adsorption phase: air is continuously fanned through a chamber, CO2 and water are adsorbed.
- Vacuum creation phase: inthis phase, the chamber is pumped toward vacuum.
- Desorption phase: at elevated temperatures, and lower (partial) pressures, the CO2 & H2O desorb
