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 9m3

usable gas from a 230

barg cylinder

• Have to be chained in an
• utside store
• Often and auto change-
• ver panel
• Difficult to transport –

heavy

4

Cylinder gas - Pallets

• Manifolded cylinder pallet,

(MCP).

• 8-16 cylinders connected to

common outlet

• Typical usable capacity
• f 150m3
• Storage pressure 180 to 300

barg

• Need fork-lift
• Change-over panel
• Normally at least 3 packs
• n-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 0C

• Re-filled on site from “cryo

truck”

• 230 litre vessel = 140m3

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?

• Nitrogen - 78%
• Oxygen - 20.9%
• Argon - 0.9%
• CO2 - 0.02%
• Other “rare” gases

make up the balance Hydrogen, neon, helium, krypton and xenon

Long term gas costs

Low initial cost but high on-going cost Higher initial cost but lower on-going gas cost Highest initial cost but lowest

• n-going cost

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?

20

To reduce food waste at the retailer and consumer by extending food shelf life via Modified Atmosphere Packaging

MAP

21

Modified Atmosphere Packaging

• Food lasts longer
• Looks better
• Keeps taste
• Allows transportation
• It helps slow down

bacterial growth and

• ther spoilage

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
• r in products “ingested by

humans”

• Nitrogen – E941
• Document – 125/06 refers

PSA and EIGA food grade gas specification

• Typical PSA nitrogen

gas generator purity specification

• Test results from

independent UKAS test laboratory

• Also fully complies with

FDA Article 21 for material compatibility

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 1st 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

• f

390,000 PKR per annum – Servicing costs 140,000 PKR per annum – Total Operating Costs 530,000 PKR

Liquid cost 4,600,000 PKR p.a Generator cost 4,600,000 PKR incl 1st year running costs Payback 4,600,000 PKR = 1.0 year 4,600,000 PKR
