A range of highly competitive and tried-and-tested solutions for CO2 management
Air Liquide has long standing experience in CO₂ management, from capture, purification and liquefaction to storage and transport from various sources.
A distinctive aspect of our CO₂ management capability is our market-leading development and application of cryogenic processes, which involve the use of extremely low temperatures to separate gases.
Cryocap™ is a technological innovation for CO₂ capture that is unique in the world. The variety of processes we have developed can be adapted to specific applications in combination with a number of other Air Liquide technologies, such as adsorption and the use of membranes.
- Cryocap™ H2 combines cryogenic and membrane technologies to produce hydrogen
- Cryocap™ FG captures CO₂ from flue gases and is of particular value to sectors such as refining or cement production
- Cryocap™ Oxy captures and purifies flue gases to produce higher quality CO₂, with lower levels of impurities
- Cryocap™ Steel can be retrofitted to steel production processes or installed new to boost process efficiency
- Cryocap™ XLL offers large scale CO₂ liquefaction, with low operational expenditure and high rates of CO₂ recovery
Recticap™ is a streamlined version of our proprietary and well referenced syngas cleaning technology Rectisol™, specifically tuned for CO2 capture. It is optimized for large-scale production of decarbonized hydrogen by ATR, and delivers high purity gaseous CO2.
We also engineer amine-based technologies to capture CO2 from syngas or flue gas. This can deliver high purity gaseous CO2 at low pressure.
With our proprietary technologies for CO2 capture (Cryocap™, Recticap™ and for integrated impurity removal, Rectisol™), and our referenced experience in the application of amine washes, coupled with our extensive operational experience, we have a range of highly competitive and tried-and-tested solutions for CO2 capture.
Port Jerome: the world’s first carbon capture plant in operation in France
In 2015, Air Liquide started operating its first industrial deployment of the Cryocap™ H₂ technology at its installation in Port-Jérôme at the largest Steam Methane Reforming Hydrogen production unit operated by Air Liquide in France.
Today, Port Jerome is one of the 4 sites in Europe able to produce Hydrogen certified low carbon. It has been integrated as a pilot site for the project CertifHy, the first Guarantee of Origin (GO) platform for Green and Low-Carbon Hydrogen.
Kairos@C, the world’s largest cross-border CCS value chain in Antwerp
Kairos@C will be jointly developed by Air Liquide and BASF at its Antwerp chemical site. By avoiding 14.2 million tons of CO2 over the first 10 years of operation, it will significantly contribute to the EU’s goal of becoming climate neutral by 2050.
Besides combining CO2 capture, liquefaction, transportation and storage on a large scale in the North Sea, the project includes several innovative technologies. Notably, for capturing the CO2 from production plants, Air Liquide will use its patented Cryocap™ technology and, for drying the CO2, BASF will apply its Sorbead® solution. The project is planned to be operational in 2025
Lhoist, a first-of-its-kind decarbonization project of lime production in France
In May, 2022, Air Liquide and Lhoist joined forces to decarbonize Lhoist’s lime production plant located in Réty, in the Hauts-de-France region. This partnership is a new step in the creation of a low-carbon industrial ecosystem in the broader Dunkirk area, enabling the reduction of CO2 emissions of the plant in Réty by more than 600,000 tons per year starting in 2028.
Air Liquide will build and operate a unit of its innovative Cryocap™ FG (Flue Gas) technology to capture and purify 95% of the CO2 arising from Lhoist’s existing lime production unit in Réty
EQIOM: developing one of the first carbon-neutral cement plants in Europe
In April, 2022, Air Liquide and EQIOM joined forces in a project named “K6” with the aim to transform EQIOM’s Lumbres plant into one of the first carbon-neutral cement plants in Europe. Through the implementation of innovative technologies, the project aims to capture around 8 million tons of CO2 over the first ten years of operation.
Air Liquide will support this initiative by supplying oxygen to EQIOM’s production process and by leveraging its proprietary technology Cryocap ™ Oxy to capture and liquefy the CO2 emissions.
