Volatile Organic Compounds (VOCs) and Odors

There is much research into the possible health and safety effects that VOCs may have on passengers and aircrew.

Existing Technologies – Carbon Adsorbents

For aircraft cabin air and other industrial transport systems, gaseous removal is currently performed using adsorption.

A popular adsorbent is activated charcoal, which has a high internal surface area, and the pollutant molecules attach to active sites on these internal surfaces. External testing has shown that it is effective at removing VOCs associated with engine oil/oil degradation.

Features

  • High adsorption efficiency for a wide variety of gaseous contaminants
  • Suitable for low temperature applications
  • No electrical power is needed
  • Simple Solution
Pall supplies combined HEPA/odor adsorbent filters for Airbus and Boeing. They are fully inter-changeable with the existing HEPA cabin air filter elements.

Pall is also carrying out an in-service evaluation of a combined particulate/VOC filter on a commercial aircraft where it is designed to filter the cockpit supply air.

Future Technologies – PCRA

The Photo-Catalytically Regenerated Adsorber (PCRA) device uses a unique combination of adsorbent and catalyst technologies to remove particulate and gaseous contamination from the cabin air.

Its operation comprises two phases:
  • Phase one - the adsorbent adsorbs the gaseous contaminants.
  • Phase two - the system oxidizes the contaminants on the adsorbent and they are purged overboard.

Features

  • Fully regenerable adsorbent system
  • Maintains a high removal efficiency throughout its period of operation
  • Removes contaminants by adsorption rather than oxidising them. The oxidation of the adsorbed contaminants would be carried out without any passengers being present
  • Operates at ambient cabin temperatures
  • Does not generate ozone
  • Low power consumption
Prototype units have been tested in laboratory conditions where the test results showed VOC removal efficiencies of greater than 90%. Further work is ongoing to develop and certify an aircraft approved unit.
