| Abstract Scope |
The new AHEX technology for treating the off gas fumes from the anode baking furnaces has been successfully demonstrated since 2018 for a complete new FTC at TRIMET Hamburg. With this new technology, the fumes are cooled in an indirect heat exchanger with water in a closed loop. Thereby, many issues with corrosion and deposits inside the traditional FTC based on the conditioning tower designs are avoided. Alumina is injected into the AHEX to keep the surfaces clean, and at the same time the alumina absorbs and removes part of the undesired components from the off gas stream. The less sticky and less humid gas due to the AHEX improves the operation conditions for the filter bags.
The paper will present performance results achieved including operational and maintenance experiences over time after the start up of the first full scale AHEX FTC installed at TRIMET’s Hamburg anode bake furnace.
