Parker domnick hunter Industrial Gas Generation
“High purity nitrogen gas generated from compressed air”
How much Nitrogen is in air?
Nitrogen - 78%
Oxygen - 20.9%
Argon - 0.9%
CO2 - 0.02% Other “rare”
gases make up the
balance Hydrogen, neon, helium, krypton and xenon
ARGONOXYGEN
NITROGEN
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….
O2N2
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)
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
Gas Supply Options
Cylinder Gas (single and multiple cylinder packs)
Liquid Nitrogen Dewars Bulk Gas Nitrogen Gas Generators
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.
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).
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.
Disadvantages of Cylinder and Liquid Dewar Supply
Disadvantages of Cylinder and Liquid Dewar Supply
Inconvenience Changing cylinders Inconsistent deliveries Poor gas quality Running out Lost production time
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 1200 -10,000 scfh
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
Disadvantages of Bulk Liquid
Inconvenience Inconsistent deliveries Lack of flexibility - expansion
difficult Running out Lost production time

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”
Membrane Generators
AIR Nitrogen
‘Fast’ water vapor and oxygen molecules diffuse through the membrane polymer.
‘Slow’ nitrogen moleculesstay within and are deliveredas product gas
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

Pressure Swing Adsorption
(PSA) Generators
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.
Pressure Swing Adsorption (PSA)
Generators
“Nitrogen gas is produced by passing ambient air through a proprietary Carbon Molecular Sieve (CMS) which adsorbs O2,H2O,CO2
