摘要： The field of this invention relates to an improved apparatus and method for chemical treatment or milling of materials that provides complete control of gases generated during the milling phase. The apparatus consists of a vapor-tight containment for all procedures before, during, and after treatment, i.e., milling which might result in the generation of noxious fumes.To facilitate the treatment of nitrogen oxide gases, air dilution of off-gases is minimized, thus enhancing the reaction transforming the gases to the water soluble form. Reaction kinetics are improved so that near-perfect scrubber efficiency can be achieved.The entire enclosure means is compartmentalized, yet substantially completely vapor-tight to provide a safe environment for personnel (i.e., during handling and inspection of workpieces) and to provide areas for other treatment of the workpieces (i.e., activation of workpiece surfaces by spraying with HCl acid). Workpieces can be transported from one compartment to the next while preserving the integrity of each compartment via a substantially vapor-tight track system between compartments. Each compartment is separated from adjacent compartments by substantially vapor-tight doors.The generation of the greater volume of noxious gases during immersion milling will take place at the immersion tank. The airspace over the tank is delimited by the cover attached to the workpiece holder. This airspace is connected through a venting means to a scrubber system which may separately or in combination treat fumes from the other compartments of the apparatus.
