off-gas system

The diluted hydrofluoric acid gas was handled by the existing off-gas system.

The iron oxides are skimmed or poured off the top of the copper and the gaseous sulfur dioxide exits the furnace via the off-gas system.

All thermal treatment technologies require an off-gas system to capture any gaseous radioactive waste produced during treatment and give the ability to manage the concentrated radioactive waste product that is produced as a result of the process.
