Measured on your gas, removed with regenerative adsorption, proven at pilot scale.
Krajete is an Austrian gas-purification specialist. We do two things: we analyse what is really in your industrial gas stream, and we remove the NOx, with regenerative zeolite adsorbers that work at ambient temperature, without ammonia, catalysts or process water. Outlets reach the 1 ppm class in industrial service.

WE MEASURE IT, THEN WE REMOVE IT, BEFORE IT DOES
Start here
Know exactly what is in your gas,
and what it would take to fix it.
The destination
NOx captured at ambient temperature,
recoverable as feedstock instead of destroyed.
1
Fixed-price analysis: €4,900, four weeks, permit-aligned report + engineer review.
2
We interpret the data on your gas and state plainly whether regenerative adsorption is the right answer.
3
A milestone-gated pilot on your own stream, with the design basis your engineering partner needs to scale.
Where we stop, deliberately
We deliver to pilot scale. Full-scale construction is executed by your engineering partner of choice.
| Dimension |
 SCR / SNCR / wet scrubbing
|
regenerative adsorption |
|---|---|---|
| Operating temperature | ~250 °C (SCR) or 850–1050 °C window (SNCR) | Ambient, no gas reheating |
| Consumables | Continuous ammonia / urea dosing; catalyst replacement | None, adsorber regenerated with gentle heat, reused |
| Fate of the NOx | Destroyed to N₂, or shifted into wastewater | Concentrated on desorption, recoverable as nitric-acid / fertiliser feedstock |
| Real-gas tolerance | Sensitive to dust, humidity, load swings | Demonstrated on hot, dusty kiln slipstream; stable day-2 removal >85% |
| Outlet level | ppm-range at best, in favourable conditions | 1 ppm class in service; sub-10 ppb in CO₂ matrices |

Fifteen years of adsorption research, down to one sentence:
send us one sample, we'll tell you what's really there.
2012
CO₂ capture collaboration with Audi, adsorption science at automotive standards
2014
Biological methanation programme — peer-reviewed publications, industrial partners, the deep gas-handling years.
2018
Adsorbent screening platform scales to industrial gas matrices.
2020
Continuous gas-handling rigs run around the clock — screening data becomes process know-how.
2024
Cement kiln slipstream campaign — ~10 ppm NOx outlets on real kiln gas.
2025
Direct air capture pilots move from lab columns to containerised units.
2026
Two services, one sequence: capture and NOx clean-up delivered as engineering programmes.
After you submit, an engineer reviews your message and replies within one business day, usually with a direct answer, sometimes with a short call if your case needs it.
No sales follow-up, no newsletter sign-up.
CO₂ transport, shipping and storage purity, trace NOx/SOx/H₂S polishing to spec, down to ppb.
Processing facilities and engine rooms with NOx point sources; containerised, low-footprint retrofit.
Kiln lines with dust, humidity and load swings, the conditions our media has already survived.
If adsorption is not the right answer for your stream, the report says so, and the analysis fee is refunded.
€4,900 fixed, with the report delivered four weeks after your sample reaches our laboratory. It includes the full composition analysis, a removal-feasibility assessment, a permit-aligned appendix and a one-hour engineer review call. If we identify no actionable pathway, the fee is refunded.
No. We deliver analysis, feasibility and pilot-scale regenerative NOx removal units. For full-scale construction we hand over a validated design package to your chosen EPC partner.
No. Our regenerative adsorption media works without ammonia dosing, without noble-metal catalysts and without water consumption. Regeneration is purely thermal.
Chemical and specialty gas producers, biogas and biomethane plants, power and waste-to-energy operators, and industrial process facilities with NOx point sources.
Stop guessing
what is in your gas.
One sample. Four weeks. A decision-grade answer, or your money back.
