The oil separation system plays an important role in improving the quality of oily metal cutting chip as recycled materials disposed from metalworking factories. In this paper, a practical circulation-type superheated steam degreasing system, which is applied to oily metal cutting chip disposed from a metalworking factory, is evaluated. In order to show the advantages of a circulation-type superheated steam degreasing system, circulation-type and once-through type systems of superheated steam are experimentally examined. The evaluation parameters of the degreasing system chosen here are the energy consumption of the system and the degreasing performance. As a result, a circulation-type degreasing system conserves more energy consumption and removes more oil from waste material than the once-through type system. Therefore, a circulation-type superheated steam waste degreasing system that can process oily metal cutting chip provides a promising energy-saving waste metal recycle system.
