Development of Recycling Technology by Using Superheated Steam

Abstract

The superheated steam has used in the field of food engineering when it has the remarkable character such as the operation in the ordinary pressure, the good efficiency for heat transfer and the treatment in the steam without oxygen. It must be applied for the recycling process to recover the metal and remove the impurity.The examples were introduced to apply the technology for the removal of oil attached to the magnesium cutting powder and the treatment of metal plated resin with painting. We succeeded to remove less than 0.1% of oil for magnesium cutting powder. It was a value enough to bring it to the reconstructive process. The painting was damaged for the metal plated resin to recover the nickel and copper in the plating dissolution process. The both were promising results of the research and development for industrial-government-academic complex in north Kyushu district.
