Launched last December, the High Efficiency Scrubber (HES) Optimizer (photo) is a digital tool that combines internal process calculations with measurements available at site to enable energy savings in the operation of Venturi-type scrubbers in wet-gas cleaning plants. Although the HES effectively captures impurity particles in wet-gas-cleaning plants, a significant pressure drop is required to achieve this. Precise adaptation of the pressure drop to the process conditions — the capacity and duty of the wet-gas cleaning in general — can enable substantial energy savings while meeting performance targets. This is exactly what the HES Optimizer is designed to do. — Metso Corp., Espoo, Finland
