CO₂ separation / carbon capture
CO₂ separation / carbon capture
Key Takeaways
- CO₂ separation (carbon capture) reduces industrial CO₂ emissions directly at source by technically separating carbon dioxide from flue gas streams.
- The CONENGA Group focuses on retrofittable post-combustion technologies for existing biogenic-fired plants.
- Market-ready amine scrubbing technology enables high CO₂ separation rates, but is energy-intensive in comparison with demanding purity requirements and involves high investment costs due to the complex plant structure. Additional emissions are also caused by amine solutions.
- The CONENGA Group continues to develop and investigate adsorption processes such as Temperature Swing Adsorption (TSA) for energy-efficient CO₂ separation.
- Data analysis, site evaluation and process engineering design are key prerequisites for cost-effective carbon capture solutions in industrial plants.

Why CO₂ capture?
The challenges of climate change require decisive action. Achieving the 1.5°C target of the Paris Climate Agreement requires not only emission reductions, but also negative emissions – i.e. the active removal of CO₂ from the atmosphere. The CONENGA Group is working intensively on both approaches – with a particular focus on technical carbon capture.
The thermal utilization of fossil fuels unbalances the natural carbon cycle. CO₂ accumulates in the atmosphere and increases the greenhouse effect, making the earth warmer and warmer. As heat and energy generation, including through combustion processes, remain necessary, CO₂ capture offers a key opportunity to reduce emissions directly at source – especially in industrial plants.
The CONENGA Group develops and evaluates technical solutions for CO₂ capture for existing industrial and energy plants with a focus on retrofitting and energy efficiency.
What is CO₂ capture?
CO₂ separation or carbon capture describes the technical removal of carbon dioxide from flue and exhaust gas streams from industrial processes. The aim is to reduce CO₂ emissions directly at the source and thereby support decarbonization targets. Retrofittable post-combustion processes for existing energy and industrial plants are particularly relevant. The CONENGA Group supports companies with analysis, technology selection, plant evaluation and the development of technical solutions for CO₂ capture in biogenic-fired plants.

Our core technologies
CO₂ absorption (amine scrubbing)
Amine scrubbing is the most established process for CO₂ separation. The CO₂ reacts with an amine solution and is separated and released in two steps (absorber and stripper).
Advantages:
- High separation efficiency
- Industrially proven and available
Challenges:
- Relatively high energy requirement, especially with high purity requirements
CO₂ adsorption (TSA)
Amine scrubbing enables high CO₂ separation rates, but is energy-intensive for demanding purity requirements and involves high investment costs due to the complex plant structure. Additional emissions are also caused by amine solutions.
Advantages:
- High potential energy efficiency
- Use of flexible sorbents
- No chemicals
Challenges:
This technology is currently still in the development phase, but shows great potential for industrial applications with high purity requirements.
