Economical and energy efficient ambient air oxygen extraction for portable and home use |
abstract |
ECONOMIC AND ENERGY ENERGY AIR OXYGEN EXTRACTION FOR PORTABLE AND DOMESTIC USE. The present invention relates to an apparatus and method for separating oxygen directly from air, operating at substantially atmospheric pressure and recovering the energy used for cooling incoming air. An ambient air inlet leads from the atmosphere to a containment vessel. A cooler has a cooled surface in the container to directly condense oxygen from the air at a substantially atmospheric pressure. The cooler cools the cold surface at a temperature higher than the nitrogen boiling point temperature and not higher than the oxygen boiling point temperature for oxygen condensation. A liquid / gas separator separates liquid oxygen from waste gases, both of which flow through separate outlets. Air is propelled by the system at substantially atmospheric pressure by an air impeller. A heat exchanger recovers cooling energy and dehumidifies incoming air by transferring heat from incoming air to the exhaust gases. |
