Simplified processes such as our quick-change spray nozzles, the improved design of our venturi rendering it completely maintenance free or the most modern plant control system (PCS) are just a few examples of the features provided by the latest generation of our plants.
Close to 100% of the waste pickle liquor (WPL) is converted back to liquid acid, which is then re-used in the pickling line. The remaining offgas passes through several treatment steps, including the exhaust fan which regulates the negative pressure in the whole upstream system preventing gas leaks, before being released via the stack into the atmosphere.
Mixed Acid used for stainless steel pickling consists of Hydrofluoric Acid (HF) and Nitric Acid (HNO3), both of which are expensive and problematic in waste streams. The CMI TOMAREG® system recovers not only these expensive acids for re-use in the pickling line but also the valuable metals contained in the waste stream.
CMI Chemline offers a system for pickling stainless steel that allows highly flexible operation of the pickling line, due to the adjustable acid concentration of the regenerated acid. TOMAREG® can produce oxide either in the form of a fine powder or coarse particles, as the plant can be delivered optionally with spray roaster or fluidised bed technology.
