Abstract
A process for neutralizing the toxic nature of organo-metallic antifouling (AF) paint particles, in intimate mixture with spent abrasive particles, derived from the abrasive blasting of ships' hulls. The spent abrasive containing the organo-metallic paint residue is collected and heated in a vapor-tight furnace which is fitted with a safety pressure release valve. When the ignition temperature of the organo-metallic paint is exceeded, the organo-metallic paint particles are oxidized to a harmless, non-toxic metal oxide, which may be safely disposed of. Volatile organo-metallic paint vapors are drawn through an after-burner so that exhaust residue consist only of non-polluting carbon dioxide and water vapor. Metallic elements of commercial value, such as tin, may be recovered from the processed abrasive, which may also be reusable. To ensure complete combustion, air is fed into the combustion furnace from a blower fan, compressor, or other external source.
