flue gas cleaning

What we offer:


What we offer is an assessment of the actual situation independent of the suppliers as well as an analysis of optimisation potential for:

  • Flue gas desulphurisation
  • SCR DeNOx
  • Dust removal

Developing specific models for FGD, SCR, SNCR, E-filters, and textile filter

The requirements for plants of flue gas treatment, whether they are existing or projected plants, are becoming more and more complex. One focus is the flexibility regarding the fuel quality and the increase of load gradients; another focus lies on reduced own consumption and an extension of operating periods between cleanings.

What we offer is an assessment of the actual situation independent of the suppliers as well as checks of your project design during the planning stage.

Flue gas desulphurisation

For FGD plants we have developed the following specific models:

  • Redispersing washing fluid
  • Droplet-wall interaction
  • Droplet collision

All of them are rooted in long-year research projects and we have developed them further for reliable use.

Examples of optimization are:

  • Pressure loss
  • Reducing the L/G proportion at constant separation performance
  • Reducing the FG wall effect
  • Nozzle positioning
  • Wall ring positioning
  • Tray inserts
  • Sump level
  • O2 injection
  • Inlet flow and outlet flow

Dust removal: E-filters, textile filters

We also offer you to optimize existing plants and installations as well as those that are still at planning stage. Our analyses do not only intend to improve the degree of separation, but also to optimize the energy consumption and to reduce the use of process media. In our computation projects we ensure the simple implementation of the project plan, and we maintain close contacts to the supplier.

Optimization can be done for:

  • Pressure loss
  • Inlet flow and outlet flow
  • Degree of separation
  • Reduction of media and energy consumption
  • Special operating modes

In addition to the flue gas flow, the models will also compute the particle distribution and the forces affecting the particles (weight, fluid particle coupling).

SCR (DeNOx)

Whether you need help in planning the project or in the later operating phase: our fluid computations and our project expertise will support you when retrofitting or optimizing your SCR installation. In cooperation with our experienced partner companies we are also able to offer you the physical model construction and the measurements in situ. Thus you will receive a comprehensive all-in-one support for your entire project.

The key focus of our surveys lies on:

  • Support of erection planning
  • Optimizing the duct geometry
  • Design and construction of static mixers and converters
  • Optimizing NH3-injection, NH3-mixing and NH3(l)-evaporators
