An acid recovery system has been successfully operated for over two years at Washington Steel Corporation, Washington, Pennsylvania. During this time the system has effectively recycled the valuable components in spent pickling acids, thereby significantly reducing the costs and liabilities associated with the disposal of these hazardous wastes. Integration of the system into existing pickle line operations has the additional benefit of improving the quality and consistency of the pickled steel product, as well as reducing maintenance on the tubs.
