Tailored Industrial gas purification solutions

At Krajete, we chose to focus on adsorptive gas purification methodologies, because they allow selective and reversible removal of specific compounds.

We offer consulting support for selecting the best solution available for our customers, we conduct feasibility studies, analyse the results and optimize the process where necessary.
Depending on your needs, we screen and combine a broad range of adsorber materials such as zeolites, alumina or silica. 

Following those steps, we implement the solution in your production line and you can start drastically reducing your emissions.

Our expertise in gas purification : 

Gas purification is the process of removing harmful contaminants from gases that are emitted into the environment. This is important because these pollutants can not only harm human health and the environment but also put a burden on a business's operativity and production processes.

For businesses that emit polluting gases, gas purification can bring several benefits.

  • Help them comply with environmental regulations and avoid fines or legal action.
  • Improve the air quality in the surrounding community, which can lead to better health outcomes and a better reputation for the business.
  • Help them to improve their sustainability by reducing their environmental impact and promoting a cleaner environment for future generations.


Overall, gas purification is a wise investment for businesses that want to operate responsibly, protect the environment, and avoid unnecessary costs linked to polluting emissions.

What is industrial gas purification?
Industrial gas purification is simply removing unwanted molecules from process gases. Think NOx, SOx, H₂S, CO, and trace hydrocarbons—often at ppm/ppb levels. The usual method is adsorption: porous solids (zeolites, alumina, silica) grab those molecules, then mild heat releases them and refreshes the bed. End result: a cleaner, steadier gas that supports safety, equipment life, and emissions compliance.
How do adsorptive methods work in gas purification?
Adsorbers expose the gas to porous solids that selectively bind target molecules. When saturated, the bed is regenerated—releasing the captured compounds while restoring capacity. Because the mechanism is reversible, materials can be reused, enabling precise removal of selected species with operating conditions tuned to the real gas.
Which contaminants are typically addressed?
Typical targets include nitrogen oxides (NOx), sulfur oxides (SOx), hydrogen sulfide (H₂S), carbon monoxide (CO), and hydrocarbons at ppm/ppb levels. These species can corrode equipment, impact health, and interfere with downstream reactions. Adsorptive purification focuses on these traces to stabilize operations and meet regulatory requirements.
How do Gas Purification Systems integrate with existing processes?
Integration follows feasibility outcomes. Adsorption stages are engineered for the site’s flow, temperature, and duty cycle. Controls and regeneration are matched to real gas behavior, so the system operates within existing process envelopes while maintaining consistent removal performance under observed operating conditions.
What information is delivered after analysis?
Clients receive a composition analysis and evidence from any conversion or compatibility tests performed. The deliverable includes a clear report and actionable recommendations for a tailored purification setup, reflecting measured species, expected removal behavior, and operating windows derived from laboratory work on the actual gas.
Can purification enable valorisation of captured components?
Yes, where practical. Because adsorption is selective and reversible, captured streams can be recovered and evaluated for potential reuse. Feasibility depends on composition, achievable purity, volume, and handling logistics. If valorisation is not viable, the process still provides cleaner gas for compliant discharge or further treatment.
