Carbon dioxide purification and drying for high purity CO2
We build on 40 years of experience in developing and manufacturing CO2 purification systems.
Codes & standards
Our CO₂ purification systems remove impurities such as moisture, O₂, or CO from carbon dioxide cost-efficiently and reliably. Through a modular combination of ReiCat Catalyst Technology with other process engineering technologies and mechanical processes, we guarantee a gas quality of 5.0 / > 99.999 % or, if required, 6.0 / > 99.9999 %. We receive a declaration of conformity for food suitability from our suppliers for all components by EN 1935/2004 and thus guarantee food-grade quality.
We tailor our systems to the needs of the industry: they impress with low operating costs thanks to maximum energy efficiency, a compact design, and low maintenance costs due to few moving parts. Building on more than 40 years of experience, we guarantee maximum availability and safety.
We offer systems in various sizes and are particularly experienced in constructing large systems.
As one of the leading suppliers in the field of gas treatment, we can refer to many references.
We will happily provide you with a list of selected references upon request.

We manufacture our systems as skids in collaboration with a broad network of certified and highly specialized suppliers and partners. The most crucial aspect for ReiCat: Quality control!
Quality control is continuously performed during skid manufacturing and between the individual disciplines. ReiCat always carries out both the quality control and the final leak and functional tests.
We support our customers on-site during the commissioning of our systems. This includes supervising the installation of the systems, filling the tanks, performing final mechanical work, and starting up the system.
The skid construction enables quick and safe commissioning.
Our systems stand for durability. We offer maintenance services to ensure this and supply spare parts, wear parts, and consumables.
We use redundant online gas analysis devices in our CO2 purification plants to ensure the desired gas quality.
Various chemical and mechanical processes are combined to achieve a purity of > 99.999 % or quality 5.0. Usually, more than a single process is required to produce the desired quality.
Depending on the operating parameters, ReiCat catalyst technology, and TSA (Temperature Swing Adsorption) dryers are typically combined with other chemical and mechanical processes. Gas-gas heat exchangers are often used, as catalytic purification requires high temperatures. The gas-gas heat exchangers reduce energy costs through heat recovery (recuperation). Our proven modular system guarantees individual, cost-effective, and high-quality solutions.
Our ReiCat Closed Loop Technology can be added to any system optionally. It ensures that our CO2 purification systems operate with up to 0% losses and emissions.
CCS: One must compress CO2 for deep geological storage. Compression requires a gas of the highest purity.
CCU: Most applications of CO2, such as the production of synthetic fuel or carbonation in the beverage industry, require a high-purity gas. The CO2 captured in the carbon capture process is usually not available in high-purity form. A gas purification system is therefore an essential component of the CCU process.
Our gas purification systems can cost-effectively produce a high-purity gas of quality 5.0 / > 99.999 % or higher from CO2 of technical quality, which is suitable for reuse or deep geological storage. We receive a declaration of conformity for food suitability from our suppliers for all components by EN 1935/2004 and, thus, guarantee food-grade quality.
Closed loops thanks to ReiCat Closed Loop Technology, highly efficient ReiCat Catalyst Technology developed in-house, and the use of few moving parts guarantee low operating costs and maintenance costs, maximum availability, and long service life of our systems.
We count all major gas producers among our customers and can provide numerous references for CO2 purification systems.
Yes. Thanks to a combination of CatOx catalyst technology and upstream and downstream purification steps, ReiCat ensures that the highest quality is always maintained.
Our suppliers provide us with a declaration of conformity for food suitability for all components, ensuring that we meet the standards of EN 1935/2004. This guarantee of food-grade quality means that the CO2 / carbon dioxide can be used in the beverage industry, among others, giving you the power to use it in various applications.
At ReiCat, we understand gas drying to mean the removal of moisture from a technical gas. By gas purification, we mean the removal of unwanted impurities from a technical gas. Those unwanted impurities may include moisture. Gas drying is therefore a sub-category of gas purification.
