Residue formation in naval Refrigeration-11 plants is a problem. The formation of these residues is attributed to the chemical reaction of the refrigerant with the compressor oil. This reaction produces hydrochloric acid, which is free to react with the oil and the metal components of the system. Spectroscopic analysis confirms the presence of the metals in the residue, and free chloride ions were found in used compressor oil in amounts that increased with time of operation of the plant. A number of potential solubilizing agents for the residues was studied. Of these, ethylenediaminetetraacetic acid EDTA and Oakite 32 a proprietary cleaning formulation were found to solubilize 90 to 95 of the residue with minimum effects on metal components of the system.
