Frank Athearn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Air cooled packaged multi-stage centrifugal compressor system
    Patent number: 7832992
    Abstract: An air-cooled multi-stage compression system using centrifugal compressors is disclosed. It is packaged in a comparable volume to a water-cooled unit having the same driver horsepower. The performance is comparable and opportunities for use of the waste heat are available. Existing water-cooled units can be retrofit to run in an air-cooled mode. Special applications such as combined air compression and nitrogen compression useful in air separation applications are presented. The circulating cooling air can make the unit into an air filter of its surrounding space. Cooling air is drawn through the enclosure before being forced through the coolers above. This air movement can cool compressor housings, the control panel and the drive motors mounted in the enclosure.

  • Air cooled packaged multi-stage centrifugal compressor method
    Patent number: 7819634
    Abstract: Provided is a method including routing a compressed gas from a centrifugal gas compressor through at least one of a plurality of air coolers, and directing air flow through the plurality of air coolers, wherein the plurality of air coolers are arranged adjacent to one another in a single plane that is transverse to the air flow. Further provided is a method including removing tube cores from a cooler chamber of a liquid cooler of a centrifugal gas compressor, coupling a chamber port of the cooler chamber to a first port of an air cooler, and coupling a second port of the air cooler to a compressor port of a stage of the centrifugal gas compressor.
