Metso targets scrubber energy savings with High Efficiency Scrubber Optimizer

Metso is launching the High Efficiency Scrubber (HES) Optimizer, a digital tool that, it says, 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.

During the last decades, Metso specialists have built a vast technical knowledge base on wet gas cleaning, enabling continuous improvement of the operation and performance of gas cleaning equipment and entire plants, it says. The optimiser tool consolidates this.

The High Efficiency Scrubber captures impurity particles in wet gas cleaning plants. However, 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.

Leif Skilling, Director, Gas Cleaning at Metso, said: “We are excited to launch the High Efficiency Scrubber Optimizer. Together with the Wet Electrostatic Precipitator (WESP) Optimizer we introduced last year, there is a significant increase in the flexibility of our gas cleaning plants and solutions. It allows the consumption of electrical power and water to be reduced, while still meeting the overall performance targets.”

Metso stated the benefits of the Metso High Efficiency Scrubber Optimizer including:

  • Adapts pressure drop to process conditions, enabling energy savings;
  • HES and WESP sections can be jointly optimised:
    • Increased energy savings potential;
    • Supplements WESP low load optimisation: ensuring that performance targets are met while the WESP Optimizer equipment protection sequence is running; and
  • Enables faster and more accurate online support from Metso experts.

The HES Optimizer uses existing instrumentation and is always tailored to the needs of the specific customer by Metso experts, the OEM says. Commissioning and online support services are available as part of the HES Optimizer licence.
