Nitrogen Gas Generation 1

Traditional Methods of Supply 2

Traditional nitrogen supplies from typical gas companies • Cylinder gas (single and manifolded cylinder packs -MCPs/Quads) • Liquid nitrogen dewars (Mini Tanks) • Bulk gas 3

Cylinder gas – Individual cylinders • Individual cylinders • Pressure : 180-300barg • Typical capacity of 9m 3 usable gas from a 230 barg cylinder • Have to be chained in an outside store • Often and auto change- over panel • Difficult to transport – heavy 4

Cylinder gas - Pallets • Manifolded cylinder pallet, (MCP). • 8-16 cylinders connected to common outlet • Typical usable capacity of 150m 3 • Storage pressure 180 to 300 barg • Need fork-lift • Change-over panel • Normally at least 3 packs on-site – 1 empty, 1 in use and 1 full. Each charge rental. 5

Mini bulk Typical Sizes: • 150, 200, 230, 950, 1500 and 2000 litres Liquid nitrogen @ minus 196 0 C • Re- filled on site from “ cryo truck” • 230 litre vessel = 140m 3 usable gas 6

Bulk gas • Insulated vessel with evaporators • Re-filled by tanker • Located outside on concrete plinth to support weight • Large stored volume for 1-2 weeks supply 7

Traditional Supply Methods Summary • Inconvenient • Long term agreements • You don’t know what you are getting • Wasteful – Return to Gas Supplier gas that you have paid for. • The most Expensive option.

The Future of Nitrogen Supply 9

What is nitrogen gas? • “ A colourless, tasteless, odourless, inert gas that forms 4/5ths of the earth’s atmosphere ” A computer rendering of the nitrogen molecule N2.

How much nitrogen is in air? OXYGEN • Nitrogen - 78% • Oxygen - 20.9% ARGON • Argon - 0.9% • CO2 - 0.02% • Other “rare” gases make up the balance Hydrogen, neon, helium, krypton and xenon NITROGEN

The CompAir Alternative 12

CN2 range Features and Benefits Features Benefits Highest efficiency, highest output Providing nitrogen gas at the lowest stable cost nitrogen gas generator Unique Energy Saving Minimised compressed air use, saving energy, money and Technology (EST) the environment Market leading low maintenance Long life technology; saving money, the environment and expensive factory down-time Unique 5 year warranty The assurance of reliable gas supply to prevent expensive factory down-time Unique industry compliance, food Providing a third party validated industry compliant gas and pharmaceutical safe quality, ensuring process and product quality to prevent expensive product recalls Gas quality control system Monitoring and controlling the gas parameters, to ensure high quality reliable gas to prevent expensive production waste and recalls Remote monitoring Monitors the right gas quality from a central location to prevent expensive production waste and recalls

Long term gas costs Low initial cost but Higher initial cost high on-going cost but lower on-going gas cost total cost Highest initial cost but lowest on-going cost time

Who can benefit from this technology? 15

Where do we sell Nitrogen gas generators?

Pharmaceutical, Universities & Research • Centralised system to feed a ring main supply for laboratories or other applications. • Chemistry labs • LC/MS suites, • Spray drying • Chemical engineering • Hypoxic chambers. • Purities : 10PPM to 5% + 17

Pharmaceutical • Primary product manufacturing – – Blanketing reactor vessels – Blanketing product – Product push through pipe- work • Finished product – Filling – Packing 18

Pharmaceutical grade Nitrogen • EIGA specification • FDA Article 21 • CompAir N2 Generators independently tested by UKAS laboratory. • Compliant with both. 19

Food Industry: Why are gasses used? To reduce food MAP waste at the retailer and consumer by extending food shelf life via Modified Atmosphere Packaging 20

Modified Atmosphere Packaging • Food lasts longer • Looks better • Keeps taste • Allows transportation • It helps slow down bacterial growth and other spoilage mechanisms 21

Specification for food grade nitrogen • What is food grade Nitrogen? • Is ultra low oxygen necessary? • European Industrial Gases Association – EIGA / JECFA • Directive 89/107/EEC • Specification for Nitrogen used on or in products “ingested by humans” • Nitrogen – E941 • Document – 125/06 refers 23

PSA and EIGA food grade gas specification Component Standard N2 GD N2 PSA • Typical PSA nitrogen E941 Achieved gas generator purity Assay EC >99% 99.15% Inert Gas specification Odour EC • Test results from Moisture EC <0.05% <0.01% independent UKAS test CO2 EC 1.12ppm laboratory CO EC <10 vppm < 1ppm • Also fully complies with NO/NO2 EC <10 vppm Below FDA Article 21 for detection <0.5ppm material compatibility THC EC <100 ppm Below Limit of Detection Residual EC 1% O2 0.85% Gases (O2) 24

CompAir Nitrogen Generating – The Benefits 26

Typical cost comparison To calculate payback depends on local market conditions, typical example • Liquid costs comprise: – 37 PKR per m3 for the nitrogen gas (20m3/hr) – 740,000 PKR rental for tank and ancillary equipment – 5000 PKR per delivery (50 deliveries per annum) – 10% Boil off 326000PRK per annum • ∴ annual costs are – gas 20m/hr x 37 PKR x 4,400 hours = 3,260,000 PKR – rental 740000 PKR = 740,000 PKR – delivery 50 x 5000 PKR = 260,000 PKR – Boil off = 325,000 PKR – Total = 4,600,000 p/y

CN2 typical capital costs example To produce 20Nm3/hr Nitrogen at < 0.5% O2 • Generator costs comprise: 2,900,000 PKR CN2- 35P Nitrogen Generator 500,000 PKR Pre-treatment system 592,000 PKR Buffer tanks and ancillary pipe work 4,000,000 PKR Total Typical Capital cost 1 st year assuming above flow and purity *

CN2 running costs example To produce 20Nm3/hr Nitrogen at < 0.5% O2 • Generator requires: – Compressed air of 68Nm3/hr at 7 barg – To produce 1 Nm3 of air you require 0.111 kw/hr of power – 68Nm/hr of air x 0.111 kw = 7.54 kw/hr – 7.54kw/hr x 4,400 hours = 33,176 kw per annum – Assuming 11 PKR per kw/hr electricity cost this would give a running cost of 390,000 PKR per annum – Servicing costs 140,000 PKR per annum – Total Operating Costs 530,000 PKR

Typical Payback Example PKR Liquid cost 4,600,000 PKR p.a 4,600,000 PKR incl 1 st year running costs Generator cost 14800K Payback 4,600,000 PKR = 1.0 year 4,600,000 PKR 11100K Annual cost 4,600,000 3 year cost 13,700,000 7400K Generator 3700K Annual cost incl. maintenance 530,000 3 year cost incl. capital 5,600,000 1 2 3 Year
