A project was undertaken to develop and demonstrate a prototype automatic cleaning system whereby a BALL POWDER still could be cleaned without personnel entering the still. Manufacturers of still cleaning equipment were contacted and their various systems reviewed. The Sugino Jet cleaner was selected for onsite testing. The inside of a 1,000 gallon still was coated with a layer of nitrocellulose and cleaned using the Sugino equipment. The high pressure water stream removed the material from the walls and the nitrocellulose was flushed out through the bottom value. The feasibility of effectively cleaning a hardening still while reducing personnel exposure to potential hazards has been clearly demonstrated.
