Technical, environmental, and economic feasibility investigation of an innovative dry washing process for metal degreasing

Abstract Industrial washing is essential in manufacturing and many other technological fields. Nowadays, steam the most common technique. However, it involves chemical solvents which are potentially noxious for environment difficult to be disposed of. Therefore, there a growing demand alternative techniques that would ensure low operating costs, extensive productivity, high efficiency, environmental sustainability, good compatibility with different materials, safe conditions. A fluidized bed (FB) represents promising satisfy market requirements. In this study, prototype of FB machine degreasing pressure vessels was designed, built, compared current solvent machine. The scope work assess technical, environmental, economic feasibility device industrial washing. analysis variance (ANOVA) carried out detect process parameters influencing cleaning. optimal were identified based on experimental results. Life cycle assessment (LCA) cost performed evaluate impacts, costs. results confirmed validity technology as an thanks its higher cleanness, minor impact comparable productivity.
