Liquid carbon dioxide spray dry cleaning system and method

Abstract

An apparatus includes a storage tank configured to store liquid carbon dioxide. The apparatus also includes a cabinet configured to seal an interior space. The apparatus further includes a nozzle configured to spray the liquid carbon dioxide from the storage tank into the sealed interior space of the cabinet such that the liquid carbon dioxide leaving the nozzle changes into a two-state flow. The apparatus may also include a carbon dioxide recovery system configured to draw gaseous carbon dioxide from the sealed interior space of the cabinet, convert the gaseous carbon dioxide into a liquid state, and return the carbon dioxide in the liquid state to the storage tank. The carbon dioxide recovery system may include at least one compressor configured to pressurize the gaseous carbon dioxide and at least one condenser configured to cool the pressurized carbon dioxide from the at least one compressor.
