Technology
•Use of standard adsorbents - formed
into hollow fibres (as opposed to beads)
•Perfect recipes and manufacturing
techniques to “spin” adsorbent fibres
from molecular sieving materials
targeting the removal of contaminants
from gas streams including:
- CO2, moisture, H2S , Helium,
Methane and hydrocarbons.
•Can be constructed as composite and
multilayered to tackle multi-component
contaminants.
•Patented design and manufacturing
process
Zeolite adsorbent crystals
Adsorbent hollow fibres

13. Project to develop
regenerative fibres
•Initial studies have shown that it is
possible to add an electrically
conductive outer layer to the fibres.
•Adding heat along the fibre speeds
up the process of regeneration.
•Faster cycle times will enable bed
size to be reduced.
•Zero purge air requirement for
regeneration (current technologies
use 20 – 25%)

14. Technology - benefits
Benefit Comment
High Efficiency
High surface area/volume ratio (>3000 m
2
/m
3
)
compared to state of the art monoliths (800-1000
m
2
/m
3
). Low vacuum/thermal swing requirements for
regeneration.
High added value products
The manufacturing process depends on the patented
technology and process know-how. Sales will be
targeted at high added value applications where there
are technical advantages over existing technology.
Lightweight, compact and low
energy use
Products can be configured and operated in many
ways, horizontally, vertically, or coiled. They are
particularly suitable for limited space, weight and power
applications.
Robust
Use of multiple layers enables high reliability products
to be fabricated that can withstand handling and
vibration during operation and maintenance.

Advantages
Large surface area, providing excellent kinetics
Minimal pressure drop as compared with packed bed technology
- Energy saving, Ease of breathing
No attrition, channeling, by pass within bed (no special filling technique)
Modules can be placed in any orientation
Fast regeneration due to open, accessible pore structure
Can remove multiple contaminants

•The maximum pressure drop reached by the packed bed (with 1.09 mm pellets) is
6000 Pa/m corresponding to an interstitial velocity of 1.2 m/s. The same pressure
drop figure (6000 Pa/m) is not reached in a NANPOR™ test hollow fibre module
(test unit dimensions of 50 fibres, 2.0mm diameter and 1.0 mm thickness) until
the interstitial velocity is approximately 17 m/s.
•That represents an increase in throughput of 1400%. For a given interstitial
velocity, the pressure drop of monolithic form and hollow fibre modules were
found to be considerably lower than that of a packed bed of same length.
•Even with less adsorbent weight stored within the hollow fibre modules (and
monoliths) compared to a similar dimensioned packed bed, their surface area will
allow for an improvement in adsorption performance for a comparable sized unit,
hence, the dp of the hollow fibre module is less and it’s performance is better than
a comparable packed bed.
