New facility for processing flue gas treatment residues

The flue gas treatment residue processing facility being built at the Högbytorp site of the Swedish recycling company Ragn-Sells will collect and wash residues from industrial processes, enabling the recovery of various commercial salts. Following a joint project development phase, the client, Ragn-Sells Treatment & Detox AB, has commissioned the Swiss cleantech company Hitachi Zosen Inova (HZI) to supply and integrate the entire process technology.

With the objective of creating a sustainable circular solution, once commissioned the installation will extract useful materials such as various salts such as potassium chloride, sodium chloride and calcium chloride as well as ammonium sulphate from the residue. These materials can then be reused for industrial or chemical purposes.

The solution produced by the washing process will then be vaporised in a distillation process, with the crystallised salts separated out. After that the cleaned residue will be dewatered and used as feedstock for new production processes.

Work to build the relevant section of the building will begin in autumn 2020, and assembly of the process technology will follow in January 2021.
