Among the different flue gas treatment processes, the injection of dry sorbent fits particularly well with the needs of the glass industry. The benefits using dry sorbent injection include technical simplicity, lower overall cost for the investment, and low maintenance costs for flue gas treatment. Lhoist offers Sorbacal SP, a specialised porous hydrated lime product specifically designed to reduce sorbent consumption while reducing waste residue production. This product further enhances the benefits of utilising dry sorbent injection compared to other methods. Additionally, in order to address increasing market demand for flue gas desulfurization, Lhoist has also developed Sorbacal SPS, a porous hydrated lime that exhibits enhanced desulfurisation performance. The flue gas removal performance of these sorbents has been studied in a flue gas pilot plant designed to stimulate operating conditions found in the glass manufacturing industry. These results compare favourably to those obtained during an actual industrial trial performed at a glass factory.
