Abstract: A device and a method for depositing undissolved materials, in particular undissolved silicon compounds, from a pickling fluid in a pickling plant. A pickling circuit of the pickling plant has a pickling tank for pickling metal strips, a return line between the pickling tank and a circuit tank, a circulation pump for circulating a main volume flow of pickling fluid from the pickling tank, and a heating device arranged in a pressure line between the circuit tank and the pickling tank. The device includes a flocculation device for introducing at least one flocculant into the main volume flow, and a deposition device in the circuit tank and preferably designed as an inclined clarifying device, for the sedimentation of undissolved materials directly from the main volume flow. When pickling silicon-containing steel strips (electrical steel strips), an at least two-stage flocculation can be carried out using two or more mixing zone containers.

Abstract: An aqueous cleaning solution that has been previously used to remove deposits from a nuclear steam generator (or other vessel) is reused after being transferred from the steam generator into an external vessel. The spent cleaning solution may be reconditioned and reused in a further cleaning of the same steam generator or a different steam generator. The different cleanings being accomplished by the cleaning solution may be of the same type or different types (e.g., iron oxide removal and/or copper removal).

Abstract: A system and method of economically converting a spent first pickling acid solution that contains hydrochloric acid, water and ferrous chloride into a suitable second pickling solution. Sulfuric acid is added to the first pickling acid solution. This produces a regeneration solution. In the regeneration solution, the sulfuric acid reacts with said ferrous chloride and water to produce ferrous sulfate heptahydrate and hydrochloric acid. The regeneration solution is cooled to promote precipitation of the ferrous sulfate heptahydrate from the regeneration solution, therein creating ferrous sulfate heptahydrate crystals and a second pickling acid solution. The second pickling acid solution contains both hydrochloric acid and sulfuric acid. The ferrous sulfate heptahydrate crystals are separated from second pickling solution. The ferrous sulfate heptahydrate is sold commercially and the second pickling acid solution is used to directly pickle ferrous metal.
