ABSTRACT:
A new aqueous-based process for cleaning organic residues from industrial equipment, reactor vessels, pipelines, valves, manufactured products, industrial components, and appurtenances. The invention employs hydrogen peroxide, and can be aided by iron and/or other catalysts or enhancers. The process is used to clean glass, stainless steel, metal, ceramic, or plastic surfaces that have become soiled, coated, or sorbed with organic material from pharmaceutical, food processing, industrial, biological, or manufacturing practices, including, but not limited to, food grease, machinery grease, oils, asphalt tar, pharmaceutical tar, biological fermentation products, polysaccharides, paints, organic dyes, glues, rubber cement, xanthan gum, aliphatic materials, or aromatic materials. Said organic material that can be removed includes solid, gelatenous, or viscous materials that coat, cling, sorb, or stick to surfaces.
