Pickle liquor can come in many forms; carbon steels with an alloy content of less than 6% are often pickled in hydrochloric or sulfuric acid. Most pickling tanks initially contain hydrochloric acid, diluted to 14-16% by weight. Hydrochloric acid (HCl) is used in a variety of industrial processes including: refining ore for the production of tin and tantalum, pickling and cleaning of metal products, electroplating, cleaning boilers, neutralizing chemically basic systems, manufacturing fertilizers, dyes, textiles and rubber, and preparing various food products. But we wanted to use orthophosphoric acid for pickling. For steels that have a higher carbon content, a two-step pickling process is required, with additional acids used (phosphoric, hydrofluoric, and nitric acid). A prime reason is that the acid can be largely exhausted prior to being discarded, thereby reducing the waste disposal problem. Meanwhile, the acid in the pickling solution slowly penetrates into the cucumbers. The reclaiming of hydrochloric acid from spent pickle solution is discussed, and one process, using a fluidized bed reactor, is evaluated. Finally it should be mentioned that recovery rate at HCl Acid regeneration plants is almost 100% and a closed utility circuit is possible.
