Abstract
Superalloy grinding swarf was treated with supercritical co2 alone, and with various modifiers. Experiments were conducted in a downflow batch mode at pressures of 0 to 5,000 psig, temperatures of 20 deg. to 250 deg. C, and times of 15 to 240 min using up to 25 g of solvent per gram of swarf. Organic dissolution increased with pressure almost linearly to 5,000 psig. Temperature affected dissolution slightly at lower pressure, but not significantly at higher pressure. Certain alcohols used as modifiers dramatically improved organic dissolution. The solvent, modifier, organics, and solids were easily recovered as separate products.
