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

How molecular sieving membranes separate feed gas into permeate and retentate streams by molecular size

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.
