    Abstract: A process chamber assembly for use with a substrate and a flow of process fluid includes a vessel and a spray member. The vessel defines a chamber. The spray member includes at least one spray port formed therein adapted to distribute the flow of process fluid onto the substrate in the chamber. The spray member is operative to rotate about a rotational axis relative to the vessel responsive to a flow of the process fluid out of the spray member through the at least one spray port.

    Abstract: Cleaning apparatus having multiple wash tanks for washing articles in a carbon dioxide dry cleaning system employing a liquid carbon dioxide cleaning solution are provided. Cleaning apparatus having multiple wash tanks of the present invention may provide improved thermodynamic efficiency by allowing carbon dioxide vapor to be transferred between wash tanks rather than condensed. Cleaning apparatus having multiple wash tanks of the present invention may have a lower capital cost than multiple cleaning systems having single wash tanks. Cleaning apparatus having multiple wash tanks of the present invention include a first wash tank for contacting a first article with liquid carbon dioxide cleaning solution, and a second wash tank for contacting a second article with liquid carbon dioxide cleaning solution. The second wash tank is in fluid communication with the first wash tank. Methods of utilizing such cleaning apparatus are also provided. Coating apparatus having multiple coating tanks and methods of utilizing such coating apparatus are also provided.

    Abstract: A method for conserving carbon dioxide vapor in a carbon dioxide dry cleaning system employing a liquid carbon dioxide cleaning solution to clean articles, where the method includes removing carbon dioxide vapor from a wash tank to a vapor tank, storing the carbon dioxide vapor in the vapor tank; and charging the wash tank with carbon dioxide vapor from the vapor tank. The method may be performed as part of a wash cycle that includes filling the wash tank with cleaning solution, washing articles to be cleaned in the wash tank, and emptying the cleaning solution out of the wash tank. An apparatus may also be employed for conserving carbon dioxide vapor in a carbon dioxide dry cleaning system employing a liquid carbon dioxide cleaning solution to clean articles, where the apparatus includes a wash tank for contacting the articles to be cleaned with the liquid carbon dioxide cleaning solution, a working tank for storing liquid carbon dioxide cleaning solution, a vapor tank for storing carbon dioxide vapor, a first piping system providing fluid communication between the wash tank and the vapor tank, where the first piping system includes a first line and a first valve residing in the first line, and a second piping system providing fluid communication between the working tank and the wash tank. Methods and apparatus for collecting liquid carbon dioxide in a collecting tank are also provided.
