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….N2O2
4 By removing oxygen we can ... Prevent oxidation of metals, polymers and chemicalsStop 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 DewarsBulk GasNitrogen Gas Generators
7 Disadvantages of Cylinder and Liquid Dewar Supply CostHigh gas cost, rental, delivery, demurrage charges.Waste - unused gasNo control over price increases from gas company.The most expensive supply method.
8 Disadvantages of Cylinder and Liquid Dewar Supply SafetyDangerous, 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 SafetyAccording 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 InconvenienceChanging cylindersInconsistent deliveriesPoor gas qualityRunning outLost 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 varyTypical user would require ,000 scfh
12 Disadvantages of Bulk Liquid CostRequires long term, highly restrictive contracts between gas company and end userGas lost / wasted through evaporation 2.3% per day at bestNo control over price increases from gas companyUsually requires building permits / license from local authorities
13 Disadvantages of Bulk Liquid InconvenienceInconsistent deliveriesLack of flexibility - expansion difficultRunning outLost production timeBACK
14 The Alternative: Gas Generation Technologies Parker domnick hunter Industrial Gas GenerationThe Alternative: Gas Generation Technologies1) 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 systemsMarkets: commercial, mobile, industrial and aerospace
16 Organization82 Combined Divisions (between geographical and functional)Located in 36 countries around the globe38 Major brands
17 Domnick Hunter Division Company founded in 1963Originally a company from the United KingdomAcquired by Parker Hannifin Corporation in 2006 for close to half billion DollarsMaintains a leadership position in the market with close to 40% shareMore 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.AIRNitrogen‘Slow’ nitrogen moleculesstay within and are deliveredas product gas
20 Key characteristics - membrane generators Flow and purity limited typically used for purities of <99.9%High maintenance cost / activated carbon towerLess durable to harsh plant conditionsExtremely sensitive to temperature and contamination
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,CO2Small molecules are trapped in the sieve,nitrogen passes through.NitrogenInlet airOxygen
24 Carbon Molecular Sieve (CMS) Small oxygen molecules trappedLarger nitrogen molecules are notCMS
25 Key characteristics - PSA generators Higher Purity Nitrogen - 95% to %Flow 1-10,000 scfh +Low maintenance costMore durable than membrane technologyLess sensitive to temperature variations than membranesNever have to replace CMS if maintained properly
