Concentration and density measurement of H2SO4 – Sulfuric Acid Production
With the high sensitivity of sonic velocity to sulfuric acid concentration, the LiquiSonic® sensors can achieve an unmatched accuracy of ± 0.03 wt%. LiquiSonic® overcomes the dual sensitivities of both conductivity and density by generating a clear signal in the concentration range of 80 – 100 wt% H2SO4 as graphed below to offer reliable, real-time process data. In the event of acid degradation to a highly corrosive level under 95 wt%, LiquiSonic® detects that critical acid “runaway” to curb the probability of heat-exchanger or other component damage, enhancing process safety and control.
The inline LiquiSonic® analyzer reduces manual laboratory measurements, saving labor and material costs in a typical laboratory titration budget for sulfuric acid measurement:
– sampling time: 15 minutes
– sampling frequency: 6 times per day
– investment payback within 13 months
Additional benefits of LiquiSonic® measuring systems include:
– easy, user-friendly installation (plug&play)
– excellent long-term stability
– one sensor for all applications (reduced investment costs)
– comprehensive diagnostic capabilities
– suitability for all needed concentration ranges with high accuracy
– enhanced process control and safety
