Breathing air purification; Desiccant vs. refrigerated
- Deltech Engineering, Inc., New Castle, DE (US)
Carbon monoxide (CO) is a common contaminant of ambient air - levels as high as 200 ppm are not uncommon in urban, industrial, or high automotive-traffic areas. Carbon monoxide may also be produced by the oxidation of lubricating oil in overheated compressors. Air from an oil-lubricated compressor, even when an aftercooler is used, often contains significant quantities of oil mist and vapor. Even where a breathing air (non-oil-lubricated) compressor is used , oil. levels in the air taken into the compressor can still exceed Grade D standards, especially in industrial environments. Other contaminants (gaseous hydrocarbons, particulate matter, and odors), while not addressed by the Grade D criteria, are also present in harmful or objectionable levels in industrial environments; therefore, they must be taken into account in the design of the air purification systems. This paper discusses two basic types of breathing air purifiers: desiccant and refrigerated purifiers.
