Air Phaser Environmental

Question 1: Describe the air flow configurations in an Air Phaser system.

Depending on what type and concentration of VOC and/or odor is being treated, an Air Phaser system can be configured one of 3 ways. The first way is called an Injection configuration. The second way is Flow Through and the third way is a Hybrid configuration.

Question 2: Describe the Injection configuration.

In the Injection arrangement, Air Phaser draws in ambient air into it’s NTP field, energizes the air to produce the reactive oxygen species and then immediately injects the activated species into the process duct to treat the pollutants. This is the recommended configuration where a large air volume of very dilute contaminants must be treated and the lesser effectiveness of injection is ok.

Question 3: Describe the Flow Through configuration.

The Flow Through system passes all contaminated air through the NTP field. This has the maximum efficiency as all electrical bombardment, electrical and ionic forces, with the shortest lived and most active oxygen species and radicals all participate in the oxidation and reduction of the pollutants. Note that this is the preferred configuration for difficult to treat pollutants and that it is possible to combine a number of NTP cells in series and series parallel flow if need be.

Question 4: Describe the Hybrid configuration.

The Hybrid arrangement draws some polluted air into the NTP field and injects that activated air into the process air to effect treatment of all the air. A modification of this might draw inside plant air that is odorous into the NTP field for activation and injection into the process. This helps keep the factory’s fugitive emissions down while still treating the process air.

Question 5: Describe some operation possibilities with Air Phaser.

The NTP field in Air Phaser has a catalyst as an integral part of the NTP field cells, which can be chosen to match the application, and it has an outlet catalyst which also can be of the most beneficial type for the pollutant being treated. The NTP field strength of Joules / Liter of pollutant volume and/or Joules / cm2 cell area can be varied as needed to obtain the destruction efficiency desired. Because all cell materials are either alumina ceramic or metal, exothermic reactions are permissible with exit temperatures up to 300 C.

Question 6: Describe the Ozone considerations with AirPhaser.

The AirPhaser NTP field creates a range of reactive oxygen and hydroxyl species through its electron bombardment, electrical potential and ionic forces. Ozone, is just one of the many species created though it is one of the longest lived of the species. When commissioning systems for organic VOC control such as odors, the NTP field is set to be just strong enough to create just enough oxygen radicals to destroy the odors with a little excess ozone that does not exceed the US EPA emission guideline of 0.08ppmv. An analyzer at the system outlet can be used in feed back mode to modulate the NTP field strength in case of varying VOC/odor load. For non-organic VOC’s such as paint and solvent fumes when a much stronger NTP field is needed and significant ozone results, an ozone destruct catalyst system is incorporated prior to releasing the treated air to the environment.

Question 7: Is the Air Phaser System Patented?

Yes, there are patents pending in the US, Canada and patents filed with the PCT organization group in Geneva, Switzerland.
