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

2. How much Nitrogen is in air?
Oxygen %
Argon - 0.9%
CO %
Other “rare” gases make up the balance Hydrogen, neon, helium, krypton and xenon

3. Why do people use Nitrogen?
A clean, dry gas (dewpoint <-70°F)
NITROGEN is an INERT gas that will remove OXYGEN from their product or production processes…. N2 O2

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

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

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

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

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

9. Disadvantages of Cylinder and Liquid Dewar Supply
Safety
According to the Dept of environmental safety at Cornell Univ.
Even with the vacuum and insulation, heat leaks in the cylinder causing the cryogenic liquid to vaporize and build pressure.
The vaporization rate will depend on several factors including the product itself, ambient temperature, condition of the cylinder’s 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.
If gas product is not used, pressure will build until it is released by a control valve.

10. Disadvantages of Cylinder and Liquid Dewar Supply
Inconvenience
Changing cylinders
Inconsistent deliveries
Poor gas quality
Running out
Lost production time

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

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

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

The Alternative: Gas Generation Technologies
1) Membrane Generators 2) Pressure Swing Adsorption generators

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

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

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

18. Membrane Generators
“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.
AIR
Nitrogen
‘Slow’ nitrogen molecules
stay within and are delivered
as product gas

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

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

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

23. Pressure Swing Adsorption (PSA) Generators
CMS
“Nitrogen gas is produced by passing ambient air through a proprietary Carbon Molecular Sieve (CMS) which adsorbs O2,H2O,CO2
Small molecules are trapped in the sieve,
nitrogen passes through.
Nitrogen
Inlet air
Oxygen

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

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