Ozone Contaminant Testing of a Molecular Sieve Oxygen Concentrator (MSOC).
Abstract
The purpose of this work was to determine if ozone, in concentrations found in the upper atmosphere, would penetrate the beds of a molecular sieve oxygen concentrator (MSOC) and enter the product or breathing gas. A three-bed oxygen concentrator was subjected to inlet ozone concentrations over the range of 0-10 ppmv. The concentrator was operated at a simulated aircraft altitude of 40,000 ft and cabin altitude of 8,000 ft, cycle times of 9.6 and 32.4 sec, and product flow rates of 10 and 70 ALPM. During this testing the ozone concentrations were monitored in the inlet air product gas, and exhaust gas. Product ozone concentrations were approximately one thousandth of the inlet concentrations, thus indicating that the concentrator was extremely effective at reducing ozone levels. The primary process responsible for this concentration reduction is an adsorption-decomposition mechanism.
