  • Process and apparatus for converting spent etchants
    Patent number: 5560838
    Abstract: Cupric chloride etchant waste is converted into non-hazardous material consisting of copper oxide and salt water. The cupric chloride etchant is preheated and a stream of the etchant is combined with a stream of preheated caustic solution. A neutralization reaction occurs in the mixed stream which is directed to a mixing tank. The reaction completes in the mixing tank without addition of heat, producing fine copper oxide which is filtered out from the salt water. The entire apparatus for carrying out the process can be integrated into a single portable unit.
