Objective
Traditional stainless steel pickling plants have now been superseded by nitric acid-free plants, which greatly reduce pollution problems associated with toxic vapours and waste solutions. The aim of this research project is to design and install a continuous treatment plant to handle the exhaust solutions typical of the new pickling process based on sulphuric/hydrofluoric acids and hydrogen peroxide to recover and recycle the acids and ferric iron. The increase in pickling efficiency, improvement in product quality and the cost savings involved would allow this technology to be extended throughout the European steel industry, without requiring large investment to modify existing pickling lines. As a result, these installations will become more environmentally friendly (no toxic effluents or dumping) and the elimination of HNO3 will significantly contribute to improving air quality in the workplace.
