Many power plants ask for a mist eliminator for higher temperatures. The concern is that a mist eliminator made from polypropylene will suffer in blackouts and operating problems which cause hot flue gas with up to 200°C (392°F) to enter into the FGD.

RPT recommends polysulfone as the base material for such application. Polysulfone has a superior temperature performance - can be operated at normal temperatures up to 180°C (356°F) and would stay undamaged even at temperatures up to 250°C (482°F) for short term.

Polysulfone has an additional advantage. The surface of the blades are extremely smooth. This means that the buildup of plugging is slowed and existing plugging can be washed off easily during the outage. For many power plants this is a superior advantage.

RPT also supplies mist eliminators made of FRP. However, the short life time of this material is an issue if frequent manual cleaning is required.
