1 Parker domnick hunter Industrial Gas Generation High purity nitrogen gas generated from compressed air

2 How much Nitrogen is in air? n Nitrogen - 78% n Oxygen - 20.9% n Argon - 0.9% n CO2 - 0.02% n Other rare gases make up the balance Hydrogen, neon, helium, krypton and xenon

3 Why do people use Nitrogen? n A clean, dry gas (dewpoint <-70°F) n NITROGEN is an INERT gas that will remove OXYGEN from their product or production processes…. O2N2

4 By removing oxygen we can... n Prevent oxidation of metals, polymers and chemicals n Stop bacteriological growth (foodstuffs & pharmaceuticals) n Reduce the risk of combustion and explosion (chemicals, reactions, processes)

5 How is Nitrogen Gas Currently supplied? n Over 90% of nitrogen gas is supplied by 4 large gas companies:- - Praxair - Air Products- Cryoinfra - Air Liquide - BOC Gases

6 Gas Supply Options n Cylinder Gas (single and multiple cylinder packs) n Liquid Nitrogen Dewars n Bulk Gas n Nitrogen Gas Generators

7 Disadvantages of Cylinder and Liquid Dewar Supply n Cost n High gas cost, rental, delivery, demurrage charges. n Waste - unused gas n No control over price increases from gas company. n The most expensive supply method.

8 Disadvantages of Cylinder and Liquid Dewar Supply n Safety n Dangerous, high pressure gas. n Heavy - involve moving and lifting. n Large, stored gas volume requires special attention (chains and adequate ventilation).

9 n Safety n According to the Dept of environmental safety at Cornell Univ. n Even with the vacuum and insulation, heat leaks in the cylinder causing the cryogenic liquid to vaporize and build pressure. n The vaporization rate will depend on several factors including the product itself, ambient temperature, condition of the cylinders vacuum, etc. The liquid-to-gas conversion rate is about 2.3% per day under perfect conditions, so the actual vaporization rate experienced can vary. n If gas product is not used, pressure will build until it is released by a control valve. Disadvantages of Cylinder and Liquid Dewar Supply

10 n Inconvenience n Changing cylinders n Inconsistent deliveries n Poor gas quality n Running out n Lost production time

11 Bulk Liquid n Cryogenic nitrogen in liquid form n Delivered and stored in large cryogenic tanks (mostly located outside facility) n Capacity of usable gas - can vary n Typical user would require 1200 - 10,000 scfh

12 Disadvantages of Bulk Liquid n Cost n Requires long term, highly restrictive contracts between gas company and end user n Gas lost / wasted through evaporation 2.3% per day at best n No control over price increases from gas company n Usually requires building permits / license from local authorities

13 Disadvantages of Bulk Liquid n Inconvenience n Inconsistent deliveries n Lack of flexibility - expansion difficult n Running out n Lost production time BACK

14 The Alternative: Gas Generation Technologies Parker domnick hunter Industrial Gas Generation 1) Membrane Generators 2) Pressure Swing Adsorption generators

15 Parker Hannifin Corporation n Annual sales of $13 billion for fiscal year 2012 (ending June 30, 2012) n worlds leading diversified manufacturer of motion and control technologies and systems n Markets: commercial, mobile, industrial and aerospace

16 Organization n 82 Combined Divisions (between geographical and functional) n Located in 36 countries around the globe n 38 Major brands

17 Domnick Hunter Division n Company founded in 1963 n Originally a company from the United Kingdom n Acquired by Parker Hannifin Corporation in 2006 for close to half billion Dollars n Maintains a leadership position in the market with close to 40% share n More than 40 Years experience in Nitrogen Generation equipment.

18 Membrane Generators n Compressed air is passed through semi- permeable polymer membranes which allow oxygen and water vapor to pass through the polymer and escape to atmosphere, leaving nitrogen as the product gas

19 Membrane Generators AIR Nitrogen Fast water vapor and oxygen molecules diffuse through the membrane polymer. Slow nitrogen molecules stay within and are delivered as product gas

20 Key characteristics - membrane generators n Flow and purity limited typically used for purities of <99.9% n High maintenance cost / activated carbon tower n Less durable to harsh plant conditions n Extremely sensitive to temperature and contamination

21 Parker - Domnick Hunter Pressure Swing Adsorption (PSA) Generators

22 CMS Operating Principles n Pressure swing adsorption using the varying molecular sizes of the gases in ambient air. n Small molecules are trapped in the sieve, nitrogen passes through.

23 Pressure Swing Adsorption (PSA) Generators Nitrogen gas is produced by passing ambient air through a proprietary Carbon Molecular Sieve (CMS) which adsorbs O 2,H 2 O,CO 2 CMS Small molecules are trapped in the sieve, nitrogen passes through. Nitrogen Inlet air Oxygen

24 CMS Carbon Molecular Sieve (CMS) n Small oxygen molecules trapped n Larger nitrogen molecules are not

25 Key characteristics - PSA generators n Higher Purity Nitrogen - 95% to 99.9995% n Flow 1-10,000 scfh + n Low maintenance cost n More durable than membrane technology n Less sensitive to temperature variations than membranes n Never have to replace CMS if maintained properly
