Proven New Technology Eliminates Disposal of Waste HCl Pickle Liquor for Galvanizers and Steel Processors Worldwide. Over the past several years, Shivas has been working to develop a hydrochloric acid regeneration system that offers a complete solution to the regeneration process. The result is a patented, low-cost Molecular Displacement Technology that produces 100% regeneration of chloride to yield a pure, 18-20% HCl and a water-soluble, solid iron co-product.
