Overview of H2SO4-Compass

Figures below demonstrate the operation of H2SO4-Compass. With H2SO4-Compass, corrosion prediction and materials selection for H2SO4 service are as easy as 1-2-3.

(1) Select the material from the dropdown list,

(2) Enter temperature, concentration, and velocity

(3) Review the prediction results

H2SO4-Compass predicts the specific gravity, the freezing point, and the boiling point of the H2SO4 acid, the acid concentration in vapor phase, the corrosion rate of the selected alloy at the specified temperature and concentration, and the remaining life of the component. In addition to that, H2SO4-Compass also plots the isocorrosion diagram for the selected alloy so as to give users a complete picture of the corrosion behavior of the selected alloy across the entire ranges of the H2SO4 acid concentration and the service temperature.

Under the prevailing conditions in Figure 1 above, carbon steel corrodes at 1.4425 mm/y, making it not a suitable material for the specified operating conditions. Figure 3 shows the performance of Zirconium under the same condition, with a significantly reduced corrosion rate of 0.025 mm/y.
