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 being dry 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. A still is disposed within one of the storage tanks and receives soiled liquid carbon dioxide as it is returned from the chamber. The pressure in the storage tank causes the soiled liquid carbon dioxide in the still to boil off. The gas is communicated to a third tank.
