Theoretical Analysis for Energy Consumption of a Circulation-Type Superheated Steam Degreasing System Applied to Oily Metal Waste Recycling
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 4
Abstract
Recycled waste material has recently become of interest because of the huge amount of natural resource consumption worldwide. It is necessary to introduce a material recycle system in municipal and industrial waste management. Quality improvement of oily metal waste disposed from metalworking factories as recycling materials is one of the issues. Here, the degreasing system plays an important role. In this paper, energy consumption of a circulation-type superheated steam degreasing system was applied to oily metal waste disposed from a metalworking factory. This system was compared to a once-through type superheated steam degreasing system. Flow rates of materials applicable to the degreasing system were estimated based on preliminary experiments, and heat and energy balances from the system were theoretically evaluated and compared between once-through and circulation type systems. As a result, a circulation-type superheated steam waste degreasing system that can process oily metal waste provides a promising energy-saving waste metal recycle system
