Typical Membrane Process Flow

  • Compressor - Compressed air is required with all Membrane nitrogen generators. If your site has compressed air available, typically between this air can be used to feed a membrane system. Depending on what type of compressor and air treatment already in place, the diagram above may change. Membrane productivity and efficiency is significantly improved by higher pressures, and they are typically operated between 100-350 psig (6.9-24.1 barg).

  • Liquid separator - Used to remove bulk water and oil from the compressed air.

  • Dryer - Depending on the application, existing equipment, and the type of membrane selected, a dryer may or may not be required.

  • 0.01 Micron coalescing filter - Used to reduce oil aerosols to less than 0.0008 ppm.

  • Activated Carbon Bed - Even after a high quality coalescing filter, there will still be oil vapor in the compressed air whenever a lubricated compressor is used. Holtec therefore always recommends the use of a large bed of activated carbon pellets in order to adsorb any remaining hydrocarbons, making the compressed air virtually oil-free. Cartridge style activated carbon filters are too small, meaning residence time will not be long enough to adsorb all oil and therefore this style of filter is not recommended. They can, however, be utilized when oil-free compressors are used in order to eliminate other contaminants.

  • Dust Filter - Dust from activated carbon would collect in the membrane separator and reduce performance, so we include a filter to remove.

  • Process Air Receiver - Depending on the application and existing equipment, an air receiver may be necessary. The best location in process flow may change depending on the application.

  • Membrane Nitrogen Generator - We hope you will choose a high quality, reliable, Holtec membrane nitrogen generator for this piece of equipment!

  • Process Nitrogen Receiver - Unlike a PSA system, membrane nitrogen production is a steady state process where nitrogen is being produced all the time at a stable rate. A nitrogen receiver is therefore not a necessity, but one can be included when the customer wants to have stored nitrogen as well.

Product Features:

  • Complete package with prefilters, carbon filter, and membrane filter.
