“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

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.

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
