Overview of H2SO4-Compass H2SO4-Compass is the only device and OS independent predictive software on the market for the modeling and prediction of corrosion by sulphuric acid. Designers, engineers, consultants, maintenance and inspection personnel can quickly assess and quantify the impact of process variables on the suphuric acid corrosion rate and the remaining life of piping, vessels, and other equipment handling sulphuric acid. Figures below demonstrate the operation of H2SO4-Compass. With H2SO4-Compass, corrosion prediction and materials selection for sulphuric acid service are as easy as 1-2-3. (1) Select the material from the dropdown list, (2) Enter temperature, concentration, and velocity of sulphuric acid, (3) Review the prediction results H2SO4-Compass predicts the specific gravity, the freezing point, and the boiling point of the sulphuric 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 range of the sulphuric acid concentration and the service temperature. Figure 1 H2SO4-Compass Corrosion Prediction and Materials Selection Guide for Sulphuric Acid Services Figure 2 H2SO4-Compass H2SO4 Corrosion Prediction and Materials Selection Guide for Sulphuric Acid Services 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. Figure 3 H2SO4-Compass H2SO4 Corrosion Prediction and Materials Selection Guide for Sulphuric Acid Services The following materials for sulphuric acid service are included in the database of H2SO4-Compass: Carbon Steel High Silicon Cast Iron (HSCI) Type 316L stainless steel Alloy 904L Alloy 31 Alloy 20 Hastelloy C-276 Hastelloy C-4 Hastelloy C-2000 Hastelloy C-22 Hastelloy B-3 Hastelloy G Inconel 625 Incoloy 825 Monel 400 Zirconium If you cannot find the material of your interest in the list above, do let us know through the Contact Us link and we will conduct the necessary research and tests to generate the required data for inclusion in the software, free of charge for licensed users of H2SO4-Compass. H2SO4-Compass's powerful applications are immensely useful for engineering design, remaining life prediction, and materials selection for sulphuric acid services.
