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

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%)

Technology - benefits

Benefit Comment

High Efficiency

High surface area/volume ratio (>3000 m2/m3) compared to state of the art monoliths (800-1000 m2/m3). 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.

RobustUse 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.
