Carbon Dioxide Dry Cleaning System
US Patent:
2005010, May 26, 2005
Filed:
Dec 21, 2004
Appl. No.:
11/020399
Inventors:
A. Preston - New Prague MN, US
Jon Turner - Edina MN, US

International Classification:
D06F029/00
US Classification:
008142000
Abstract:
A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks in communication with a compressor. A sealed cleaning chamber contains the objects to be cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. In an alternative embodiment, a single storage tank is pressurized via a compressor with gas from the cleaning chamber so that liquid solvent from the storage tank travels to the cleaning chamber through nozzles. The objects in the cleaning chamber are agitated by a rotating basket. After a prewash cycle, liquid solvent from the cleaning chamber is directed to a still. The liquid solvent in the still is boiled through a connection with the head space of the cleaning chamber. The still may be positioned within the storage tank and partially surrounded with a shroud for efficient heating of the still with gas from the cleaning chamber. During agitation, liquid solvent from the cleaning chamber may be heated and filtered.

International Classification:
F25J 1/00, F25J 3/00, F17C 7/02, B08B 7/04, B08B 3/00
US Classification:
62606, 62929, 62 521, 134 12, 134109, 134115 R
Abstract:
Gases are vented from a waste site such as a landfill, and the gases are separated into at least three streams comprising a hydrocarbon stream, a carbon dioxide stream, and residue stream. At least a portion of the carbon dioxide stream and hydrocarbon stream are liquefied or converted to a supercritical liquid. At least some of the carbon dioxide gas stream (as a liquid or supercritical fluid) is used in a cleaning step, preferably a polymer cleaning step, and more preferably a polymer cleaning step in a polymer recycling process, and most preferably in a polymer cleaning step in a polymer recycling system where the cleaning is performed on-site at the waste site.
