    Abstract: A system for the controlled addition of detergent formulations and the like to a carbon dioxide cleaning apparatus comprises: (a) a high pressure wash vessel; (b) an auxiliary vessel; (c) a drain line connecting the auxiliary vessel to the wash vessel; (d) optionally but preferably, a separate vent line connecting the auxiliary vessel to the wash vessel; (e) a detergent reservoir; and (f) a detergent supply line connecting the detergent reservoir to the auxiliary vessel. An advantage of this apparatus is that, because the detergent formulation can be pumped into the auxiliary vessel in a predetermined aliquot or amount, which predetermined aliquot or amount can then be transferred into the wash vessel where it combines with the liquid carbon dioxide cleaning solution, the detergent formulation can be added to the cleaning solution in a more controlled or accurate manner. An alternate embodiment adapted for the addition of aqueous detergent formulations and the like to a carbon dioxide dry cleaning system under turbulent conditions comprises: (a) a high pressure wash vessel; (b) a filter; (c) a carbon dioxide cleaning solution drain line interconnecting the wash vessel to the filter; (d) a carbon dioxide cleaning solution supply line connecting the filter to the wash vessel; (e) a first high pressure pump (i.e., a pump that is capable of pumping liquid solutions comprising liquid carbon dioxide) operably connected to the drain line; (f) a detergent formulation reservoir; (g) a detergent formulation supply line connecting the reservoir to the carbon dioxide cleaning solution supply line; and (h) a second high pressure pump operably connected to the detergent formulation supply line for transferring detergent formulation from the detergent formulation reservoir into the carbon dioxide cleaning solution under turbulent conditions.
