Benefits
Turn separation challenges into stronger process economics
Are valuable molecules being lost in off-gas or flare streams? Is separation limiting production capacity? Or are you looking for a more efficient way to bring emissions down? UniSieve targets the separation points where better performance can translate directly into stronger process economics.

Multiple separation ranges

Membrane technology
Separation by molecular size
When your gas stream enters the membrane, a pressure difference drives molecules towards the crystalline pores. Molecules that pass more readily through form the permeate stream; those that are retained continue as the retentate stream. The result is two streams with different compositions.

End-to-end solution
From membrane technology to a complete industrial solution
At the core sits UniSieve’s proprietary membrane technology. It enables continuous gas separation at molecular level, using far less energy than conventional methods and allowing valuable components to be recovered and reused. From there, we engineer the complete solution around the process and take it through integration, commissioning and operation on site.

1
Identify the opportunity
Review your CO₂ source, concentration, annual volume and intended destination. Together, we assess the capture opportunity, operating requirements and conditions for a viable project.


2
Validate with a pilot
Test on your own flue gas to establish relevant performance and operating data. The findings help your team evaluate technical fit and commercial potential before scaling.

Directly installed on plant

3
Deploy & operate
Once the case is proven, configure the full system around your site, operating requirements and CO₂ route. Then integrate and bring it into operation.
