For improvement of the waste metal quality of the recycled material disposed from metal working factories, the oil separation system plays an important role. In this paper, the energy consumption and degreasing performance of a superheated steam degreasing system applied to an oily metal cutting chip disposed from a metalworking factory were examined. Energy consumption and degreasing performance were compared between the once-through type and the circulation-type superheated steam degreasing systems. As a result, a circulation-type degreasing system conserves more energy and removes more oil from waste material than the once-through type system. These results show that the circulation-type system is superior to the once-through type system in terms of electric consumption and degreasing.
