One-stop-shop for your Carbon Capture project

Air Liquide

Air Liquide is a French company founded in 1902 with its first carbon capture deployment in 2015. They are present in 75 countries. Their Cryocap™ FG solution features Pressure Swing Adsorption and cryogenic treatment of CO2 to achieve carbon capture. 

They claim competitive advantage based on the following:

  1. Covering entire project life-cycle: Air Liquide covers the entire project life-cycle: license engineering services / proprietary equipment, high-end engineering & design capabilities, project management & execution services. In addition, they also offer efficient customer services through our worldwide set-up.
  2. Longstanding experience in CO2 management: CO2 management from capture, purification, and liquefaction to storage and transport from various sources. Further, they also provide services for upgrading recovered CO2 and provide it to various markets.
  3. Safety and environment-friendly: No toxic or flammable gases are used.
  4. No steam required: Cryocap FG is a solvent free solution that requires only electricity.
  5. Compact solution: Flexible layout configuration and simplified infrastructure compared to steam-based solutions. Compressors, PSA, and cryo process can be located in two different plots.

Capture technology - Pressure Swing Adsorbtion with cryogenic treatment

1.

1. Pressurization of flue gasses

The CO2-rich flue gasses are captured, compressed to a high pressure of >50 bar, and dried. (1.)  The drying process removes water and impurities to avoid freezing in the cryogenic section of the process (1ppm H2O).

1.2.2.

2. Pressure swing adsorption

The dried and compressed flue gas is sent to a Pressure Swing Adsorption (2.), where CO2 in the off-gas is pre-concentrated, and non-condensable gases are vented out. 
Adsorber is regenerated via heated off-gas from the cryogenic section.

1.2.2.3.

3. Cryogenic separation

In the cryogenic section, gas gets cooled down to -50C, where it partially condenses. This allows for CO2 recovery via a combination of partial condensation and distillations, which also allow for removal of NOx and lighter elements.
When condensed, the CO2 rich liquid falls to the bottom of a drum (3.) and gets sent to a distillation column. 
There, it is purified and re-vaporazed in the exchanger. From there, it can be re-pressurized to conform to pipeline requirements.

Reference projects

The world’s first industrial deployment of Cryocap™ technology at Air Liquide’s hydrogen production unit. This pilot project captured CO2 from their Steam Methane Reforming process, demonstrating the technology’s feasibility.
Timeline:
Operational since 2015.

Air Liquide will build a unit at its hydrogen production plant in Rotterdam, leveraging Cryocap™ technology to capture CO2 from its existing operations. The captured CO2 will be injected into the Porthos CCS infrastructure.
Timeline: Announced in December 2023, the unit is expected to be operational in 2026.

A partnership with BASF to develop the world’s largest cross-border Carbon Capture and Storage (CCS) project. Cryocap™ technology will be used to capture CO2 from BASF’s Antwerp chemical site and store it in the North Sea.
Timeline:
Announced in November 2021, the project is currently in the Front-End Engineering Design (FEED) stage, awaiting final investment decision.
