Overview and Application Examples of DewPoint-Compass

DewPoint-Compass is the only device and OS independent software tool on the market for the prediction of dew point temperatures of flue gases and the risks of dew point corrosion. Designers, OEM engineers, consultants, operation personnel, maintenance and inspection engineers can quickly determine the dew point temperatures of flue gases and the risk rankings of dew point corrosion, anytime, anywhere, on any device running any OS without the need to install or download anything. DewPoint-Compass also predicts the modes of condensation (mist condensation, film condensation or both) and the concentration of the first condensed acid at the dew point temperature.

 

Figures below show the screen shots of DewPoint-Compass.

 

Figure 1 DewPoint-Compass Predicts the dew point temperatures of flue gases and the risk of dew point corrosion.

 

Under the prevailing operating conditions shown in Figure 1 above, the dew point temperatures of Flue Gases including SO3, SO2, HCl, HBr, HF, NO2 and water vapour are predicted. Dew-Point-Compass also predicts that the first condensed acid is sulphuric acid and its concentration is 76%. The risk of dew point corrosion at the prevailing operating conditions is predicted to be "high" and that the mode of condensation is film condensation on the internal wall surface of equipment/structure.

 

The effect of the concentration of the flues gas on the dew point temperature is plotted at the bottom left of the screen. Users of DewPoint-Compass can quickly assess the impact of flue gas composition on the risk of dew point corrosion.

 

Under the prevailing operating conditions in Figure 2, DewPoint-Compass predicts that both mist and film condensation can occur to the equipment/structure and the risk of dew point corrosion is "very high".

Under the prevailing operating conditions shown in Figure 3, there is no risk of dew point corrosion.

Since DewPoint-Compass predicts both the dew point temperature and the concentration of the first condensed acid, it integrates seamlessly with CRA-Compass for the materials selection and the prediction of the corrosion rate. For example, under the prevailing operating conditions in Figure 2 above, the dew point temperature of SO3 is 130.50oC and that the first condensed sulfuric acid (H2SO4) is 76%. Using these numbers as inputs in CRA-Compass (Figure 4), the corrosion rate of alloy C-276 is predicted to 9.4767 mm/y. Please refer to this link for details on CRA-Compass.

The powerful applications of DewPoint-Compass (and CRA-Compass) are truly unlimited in engineering design, dew point corrosion prediction and risk assessment, materials selection, trouble-shooting process-related issues and failure analysis of components and systems.
