Nitrogen Overview Nitrogen Nitrogen is the 7 th most abundant chemical element in the universe and is the single largest constituent of the Earth s atmosphere (78% by volume of dry air and 75.3% by weight in dry air). Nitrogen is present in all living organisms in proteins, nucleic acids and other molecules. It is a large component of animal waste, usually in the form of urea, uric acid, ammonium compounds, which are essential nutrients for all plants. Nitrogen Applications Nitrogen gas is acquired for industrial purposes by the fractional distillation of liquid air, or by mechanical means using gaseous air (i.e. pressurised osmosis membrane or pressure swing absorption). Commercial nitrogen is often a by product of air-processing for industrial concentration of oxygen for steelmaking and other purposes it has a wide range of applications, including serving as an inert replacement for air where oxidation is undesirable:- To preserve the freshness of packaged or bulk foods In ordinary light bulbs as an inexpensive alternative to argon On top of liquid explosives for safety measures In the production of electronic parts such as transistors, diodes & integrated circuits Dried and pressurised as a dielectric gas for high voltage equipment The manufacture of stainless steel Use in military aircraft fuel systems to reduce fire hazard Filling automotive and air craft tires due to its inertness and lack of moisture or oxidative qualities (not necessary for consumer automobiles). A preferred alternative to carbon dioxide to pressurise kegs of some beers Nitrogen Boosters Booster compressors take an existing pressure and elevate this to the higher required pressure. This can be applied to air or gases including, helium, hydrogen and in particular Nitrogen. In the case of Nitrogen Boosters the customer has a supply of Nitrogen at a pressure of above atmospheric which they wish to utilise at a higher pressure for applications such as those mentioned above. As the compressor is working with a high inlet the gas requires less compression and hence the same work can be achieved with a lower power outlay. Page 3/5 23/01/2008
Standard Specification Set A standard specification set typically incorporates the following: Single or multi stage compression depending upon system pressures Gas inlet solenoid valve Gas inlet pulsation vessel (where appropriate) High & low gas inlet pressure protection switches Gas inlet pressure gauge and relief valve Pressure gauges on all compression stages Relief valves on all stages Integral inter and aftercoolers with separators on each stage of compression Automatic isolating valve on cooling water inlet (water cooled only) Electrically controlled automatic unloader/drainage (solenoid valve operated) Forced or splash lubrication oil pressure gauge (model dependent) Gas type crankshaft oil seal assembly Gas type oil filler assembly Gas type crankcase breather piped back to suction Corrosion rods and safety bursting disc in cooling water jacket (water cooled only) Compressor non return valve Controlling pressure switch, (supplied loose) Drive arrangement vee belt drive or direct coupled TEFV, IP55 electric motor Anti-vibration mounts Standard instruments are conventional switch devices. As an alternative, transmitter devices (4 20 ma) can be quoted for on request. The Standard specification listed above typically indicates the scope of supply for a typical Nitrogen compressor. Machines that are configured for other duties may differ slightly in scope of supply. Page 4/5 23/01/2008
Ancillary Equipment Items The following ancillary items are typically available for Nitrogen gas compressor sets: Starter / control panel Oil removal filtration system / Dryer Gas inlet buffer vessel Unloader Demister High pressure storage Fully Packaged Set Typically, a fully packaged set incorporates: Main equipment baseplate Starter control panel Oil Removal Filter System / Dryer Unloader Demister Note: The above scope of supply is again based on a typical Nitrogen compressor package, the scope of supply will differ depending upon the specified operating configuration of the machine.
