OXYSULF METmetallurgical processes

For a wide range of SO₂ feed gases containing dust, OXYSULF MET is used. OXYSULF MET is applied in the metallurgical industry to treat roast gases containing dust (with dust concentration of up to 180g /Nm³). The roast gas leaving the furnace is cooled to 400 – 600 °C.

The physical properties of the dust dictate the cleaning technology to be used:

• For free-flowing dust the gas stream is treated with a dry process. The cooled gas passes over the cyclone where the particulates are removed, then the gas passes over the Dry-Fil hot gas filter for a further filtration. After dedusting the gas steam is treated by the OXYSULF NK plant.
• For not free-flowing dust the gas stream is treated with a wet process. The cooled gas passes over a scrubber where the particulates are removed, then the gas passes over a WESP (Wet Electrostatic Precipitator) for a further cleaning. This is followed by further treatment in a OXYSULF NK plant.
