Abstract:
1. A gravity independent method for removal of carbon dioxide and other trace contaminants from air used in environmental control, comprising the steps of: introducing an air flow into a carbon dioxide scrubber rotor and spraying a liquid absorbent mist into said air flow; rotating said carbon dioxide scrubber rotor to accumulate and remove said liquid absorbent containing absorbed carbon dioxide and trace contaminants from the carbon dioxide scrubber rotor; passing said airflow downstream of said carbon dioxide scrubber rotor through a plurality of first air passages and a plurality of first mist separators to a liquid absorbent scrubber rotor; spraying a liquid acid wash into said air flow; rotating said liquid absorbent scrubber rotor to accumulate and remove said liquid acid wash containing liquid absorbent, carbon dioxide and trace contaminants from the liquid adsorbent scrubber rotor; and passing air flow downstream of said liquid absorbent scrubber rotor through a fan to an air exhaust, whereby carbon dioxide and other trace contaminants may be removed from the airflow in variable gravity environments.
