Nitrogen Generation Nitrogen (N2) is a dry, inert, colourless, odourless gas. It is commonly used in a wide range of industry applications because it prevents both fast and slow oxidization. Blanketing Due to its low reactivity, nitrogen is an excellent blanketing gas. Blanketing protects a product from the environment or vice-versa. Blanketing is a common practice in the chemical, food, pharmaceutical, oil and gas, glass and metallurgical industries. Modified Atmosphere Packing (MAP) The presence of oxygen inside packaged foods and beverages promotes bacterial growth and oxidation, compromising...

Canadian-made, fully CRN & ASME Certified Traditionally, nitrogen has been produced by cryogenic distillation and commercialized in the form of bulk liquid and high pressure compressed gas cylinders. Nowadays, vendor price increases, long term contracts, rental fees, have motivated the development of more efficient and cost effective technologies for on-site generation of nitrogen using pressure swing adsorption (PSA) and membrane systems. Depending on required flow and purity, both can be far more cost-effective than bulk or high pressure cylinder sources. On site equipment is the right choice....

Nitrogen System Components An on-site nitrogen generation system includes compression and pre-treatment units followed by an O2 removal step which is performed by either a pressure swing adsorption (PSA) unit or a membrane system, depending on flow and purity requirements. Nitrogen Generation System Using Refrigerant Drying and Membrane Technology — 95.0 to 99.0% Purity See available options on Page 14 Compressor with After-cooler Refrigerant Dryer Water Separator XL-F, SF + AC Filters or Activated Carbon Tower XL-G Membrane XL-SF Filter Nitrogen Generator Filter Nitrogen Receiver Nitrogen Generation...

From Air to 99.999% Pure Nitrogen Step 1: Air Compression & Pre-Treatment Atmospheric air must be compressed and treated to remove impurities before it enters the O2 removal process. Impurities include dust particles, traces of oil and VOCs compounds, low concentrations (parts per million) of CO2, CO, and water. Step 2: Dust & Oil Removal Dry compressed air is sent to an air receiver which reduces process fluctuations and guarantees smooth operation of the compressed air system and the O2 removal system. High efficiency coalescing filters are used to remove moisture and oil aerosols to 0.01 ppm...

Pressure Swing Adsorption (PSA) PSA technology is a simple, cost-effective method where atmospheric air is pressurized (50-140 psig/3.5-9.7 barg), and then fed into a vessel filled with adsorbents like carbon molecular sieves (CMS). High N2 Rates Adsorption Process Xebec’s N2X™ solution with PSA works under the principle of adsorption equilibrium and kinetic theory. Xebec’s kinetic adsorbent is highly selective to components such as O2, CO2 and water vapour, while allowing nitrogen molecules to pass through the adsorbent bed. O2, CO2, and CO molecules easily diffuse inside the adsorbent pores...

High Performance Membrane Technology When required nitrogen purity is lower than 99% and the product stream must be delivered at higher pressures (about 175 psig/12 barg), Xebec’s high-performance, hollow fiber polymer membrane solution is recommended. High N2 Rates Membrane separation is based on the difference between the permeation rates of various gas molecules through the membrane’s microscopic pores. When pressurized air feed enters the membrane modules, O2, CO2, water and other gases have a much stronger preference to diffuse and permeate through the membrane than N2 molecules. Xebec’s...
