Description

This study characterizes the off-gases produced by a 500 A inert electrode aluminum electrolysis cell operated at approximately 800 °C using gas chromatography, tunable diode laser spectroscopy, and FTIR. Results show that oxygen is the dominant process gas, with only trace amounts of hydrogen fluoride and silicon tetrafluoride detected, and no direct emissions from the primary reduction reactions. These findings provide crucial baseline data for evaluating emissions in carbon-free aluminum production processes and support the development of sustainable electrolysis technologies.
