CO₂ free air

Greencap provides a green technology for rinsing out air from CO₂ and provide CO₂ free air to closed systems such as storage rooms and battery factories.

The technology is based on the direct air capture process where zeolite is used as the CO₂ adsorbent and delivering CO₂ free air as the final product.

The presented technology involves no chemicals and provides CO₂ free air with ≤10 ppm CO₂.

Process

In some cases, battery production requires dehydrated and nearly CO₂ free air. GCS has developed a new application for delivering near CO₂-free air.

GCS’ contribution is to remove CO₂ from air that has been dehydrated by others using two sorbent beds operating alternately in adsorption and desorption mode as shown in figure to the right.

The product after adsorption is extremely low residual CO₂ content of <0.5ppm. Minimum requirement for battery production is <10 ppm and known competitors have problems reaching <20ppm. Desorption step is accomplished using treated and heated air to regenerate the adsorbent bed and recover the adsorbed CO₂.

In 2016 GCS developed a groundbreaking way to capture CO₂ from the air. Our process is based on the adsorption concept. We use an optimised zeolite as adsorbent with unique features that substantially increases the efficiency and reduces environmental impacts of CO₂ capture.
