Chinese steel giant Baowu’s Shanghai-based Baoshan Iron & Steel has inaugurated of the world’s largest acid regeneration installation on 16 September 2022. The two plants supplied by John Cockerill Industry feature the full spectrum of the very latest process technologies in this field, making it the most environmentally friendly process for acid regeneration on the marked.The Twin Acid Regeneration Plant purifies 2 x 20,000 liter per hour of spent hydrochloric acid that is led back into the client’s manufacturing process. According to the latest monitoring data, it will reduce the plants carbon footprint by 4,800 tonnes per year, and dust by 25 tonnes, all while reducing or even eliminating other waste streams including wastewater and solid hazardous waste. A compelling testimony of the Chinese steel giant’s investment into circular economy and an eco-friendlier future.Located in the client’s flat steel complex in Shanghai, the two ARPs are based on John Cockerill’s state-of the art fluidized bed technology, for highest throughput and plant availability, providing operator friendliness, as well as a small footprint and easy oxide handling. Features based on which BAOWU Steel Group opted for John Cockerill’s FB technology for the regeneration of its spent acid solution coming from the pickling process. A process during which high-strength and electrical steel strip is pickled using HCl to remove impurities from the metal surface. For this type of high alloy and silicon containing metal strip the spent acid solution, also called pickling liquor, contains a particularly high number of impurities and harmful particles. John Cockerill’s highly automated acid regeneration plants allow the recycling of close to 100% of the generated spent pickling liquor. This not only reduces the environmental footprint of the steel complex but also it’s operating cost. Additionally, the perfectly matched tank farm guarantees the efficient management of consumable process chemicals and maximizes operating efficiency, but also minimizes the environmental impact. Driven since 1817 by the entrepreneurial spirit and thirst for innovation of its founder, the John Cockerill Group develops large-scale technological solutions to meet the needs of our time. John Cockerill Industry, one of the Group’s 6 sectors of activity, designs, supplies, and modernizes cold rolling mills, processing lines, chemical and thermal treatment installations for the steel and the non-ferrous industry. It also provides state-of-the-art heat treatment technologies for the aviation, forging and casting industry, as well as surface treatment installations for all types of industries, including automotive and aviation, with a particular focus on the MRO segment. In 2021, John Cockerill achieved a turnover of 941 million euros in 19 countries on 5 continents.
