High-Purity CO₂ Recovery
- Solvent-free CO₂ capture and purification
- Fully electrified process configuration
- Combines adsorption and cryogenic separation
- Applicable to flue gas, syngas, and tail gas
- Delivers CO₂ in gas or liquid phase
- Flexible design for variable feed conditions
Traditional solvent-based carbon capture technologies often involve high energy consumption, complex regeneration systems, and operational constraints. These challenges can limit their applicability, particularly when dealing with variable gas compositions or when electrification is required.
At the same time, industries need flexible solutions capable of handling flue gas, syngas, and tail gas streams, while delivering high-purity CO₂ suitable for downstream use.
NX CryoCOOL™ redefines carbon capture by combining simplicity, flexibility, and high performance in a single platform. It enables industries to decarbonize complex gas streams, while maintaining efficiency and enabling seamless integration into broader CO₂ value chains.
Hybrid approach to CO₂ capture and purification
NX CryoCOOL™ is NEXTCHEM’s solvent-free carbon capture technology, combining adsorption-based pre-concentration with cryogenic purification in a single integrated system.
This hybrid configuration enables:
- High CO₂ recovery
- Direct production of high-purity CO₂
- Delivery in either gaseous or liquid phase
The process is fully electrified, eliminating the need for solvents and steam regeneration while reducing process complexity and environmental impact. NX CryoCOOL™ can adapt to different feed conditions through its modular configuration, making it suitable for a wide range of industrial applications.
How the Technology Works
NX CryoCOOL™ adapts to different process conditions through modular configurations, enabling efficient CO₂ capture across multiple industrial scenarios.
Flue Gas Applications
For flue gas streams with relatively low CO₂ concentration, NX CryoCOOL™ applies a two-stage separation approach:
- PSA pre-concentration selectively captures CO₂
- The concentrated stream is sent to cryogenic purification
This reduces the gas load to the cryogenic section and significantly improves overall energy efficiency. The final CO₂ stream is purified to specification and can be delivered in liquid or gaseous form.
Syngas Applications (Pre-Combustion Capture)
In syngas configurations, NX CryoCOOL™ operates as a pre-combustion capture system, separating CO₂ from hydrogen-rich streams.
- Dual PSA units separate H₂ and CO₂
- The CO₂-rich stream is routed to cryogenic purification
- Hydrogen is recovered for downstream use
This configuration enables efficient CO₂ capture at elevated pressure, high-purity hydrogen production, and minimal syngas losses.
Tail Gas Applications
For tail gas streams composed mainly of CO₂ and hydrogen, NX CryoCOOL™ enables simultaneous recovery of both components:
CO₂ is separated and liquefied via cryogenic processing
Hydrogen is recovered through dedicated PSA units
While maintaining a simple and flexible process configuration, the process achieves more than 95% CO₂ recovery and more than 80% Hydrogen recovery.
