Selective salt elimination and valorisation for sustainable water and facility management in the steel industry (SELSA)

Final report

Μεταδεδομένα της έκδοσης

The aim of the project was to develop sustainable concepts for water and facility management in the steel industry on basis of selective salt elimination and valorisation. The objectives involved reduction of fresh water consumption, decrease of salt output into the environment, prolongation of pipe service life and ensuring of high product quality. Management concepts for process water circuits with detected corrosion or scaling damages and waters with high salt concentrations were developed on basis of operational tests. Reuse of the blow-down water with reverse osmosis in blast furnace gas scrubbing circuit can reduce fresh water consumption by 76% and prolong pipe service life. Pre-treatment of the make-up water with reverse osmosis in hot rolling mill cooling circuit results in 66% reduction of fresh water consumption and eliminates the risk of hot strip corrosion during storage. In pickling lines, descaling with high pressure water jet and acid regeneration with ion exchange can reduce acid consumption considerably. Fresh water consumption for rinsing in sulphuric acid pickling lines can be reduced by 90% using microfiltration, magnetic scale separation and reverse osmosis. The developed management concepts are technically and economically feasible. The application of salt elimination techniques results in increased CO2 impact. For the valorisation of the concentrate several concepts were considered but none of them was viable. The developed management concepts are transferable to the existing and new plants. To facilitate their implementation a decision guidance matrix and step by step guidelines were developed.
