Mission “ To be pre-eminent in the technology of nano-porous composite hollow fibres and to supply high added value products and solutions to customers world-wide”

“ To be pre-eminent in the technology of nano-porous composite hollow fibres and to supply high added value products and solutions to customers world-wide”

Intellectual Property Further application - specific patents will be filed covering novel recipes, devices and where possible processes employed. Patent Summary International Patent Application No. PCT/GB2006/002509 entitled “ Hollow fibres” Number of hollow fibre recipes for robust and flexible nano-porous fibres, including a method and apparatus for processing of highly viscous dopes. UK Patent Application No. 07049349 Hollow fibre recipes, and adsorption units based on the use of conductive fibres that can be easily “regenerated”. UK Patent Application No. P402739 Advanced Compressed Air Treatment Design

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

Patented design and manufacturing process

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%)

Zero purge air requirement for regeneration (current technologies use 20 – 25%)

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 2/05/07

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.
