Wet Electrostatic Precipitators (WESP) are a necessity prior to sulfuric acid plants processing metallurgical off-gas to ensure a high-quality acid. Metso Outotec Editube WESP has a very high removal efficiency potential where dust levels in the outlet are commonly measured at below 0.5 mg/Nm3.

The Optimizer utilizes the existing instrumentation and is always tailored to the needs of the specific customer by Metso Outotec specialists. Commissioning and online support services are available as part of the Optimizer license.
