Latest Patents
One of Koivunen's latest patents is a method for regenerating pickling acids. This process involves transforming a residual acid mixture containing metals, produced during the steel pickling process, back into new HF/HNO₃ pickling acid. The method utilizes H₂SO₄ addition and evaporation, resulting in the production of metal sulphate salts, which are then converted into scarcely soluble iron jarosite and hydroxides of chrome and nickel. The crystallization process is enhanced by utilizing a side line with a higher concentration of H₂SO₄.
Another significant patent is for an immersion evaporator. This innovative device features an evaporation vessel connected to a series of pipes for feeding solutions, withdrawing concentrated solutions, and removing flue gases. The design includes a burner for liquid or gaseous fuel, which is equipped with a cylindrical combustion gas turbulence chamber. This setup optimizes the combustion process and enhances the efficiency of the evaporation system.
