- Inline measurement of sulfuric acid and oleum strength, online data processing -

Sulphur 2015, booth 4a, November 9th - 12th, Sheraton Centre, Toronto, Canada

Measuring inline, data processing online
Monitoring the sulfuric acid and oleum strength (wt%) inline, directly in the process, enhances safety and efficiency of production plants. The measuring results are available online and in real time.
Due to the physical properties of sulfuric acid and oleum, the most suitable measuring method for determining the acid strength is sonic velocity measurement. T
he LiquiSonic® analyzer by SensoTech precisely measures with only one single sensor the sulfuric acid and oleum strength in the relevant concentration ranges.

Applications
of the analyzer include, for example,

• the acid production,
• alkylation,
• oil refining,
• syngas drying,
• fertilizer manufacturing,
• mineral processing
• etching and pickling baths.

The LiquiSonic® technology
is based on sonic velocity measurement providing clear and stable measuring results with an accuracy of up to 0.03 wt%. If the measuring values exceed or fall below critical process thresholds, a signal will be sent immediately ensuring timely countermeasures can be initiated.
The real-time information significantly increases work environment safety and product quality and reduces costs caused by acid wastage and failed production.

Made of Hastelloy C-2000,
the LiquiSonic® sensor is absolutely resistant to corrosion. The robust construction requires neither gaskets nor moving parts, so the sensor is maintenance-free with long-term stability.
The installation is done directly
into the existing pipe or vessel. The measuring results are updated every second, and for process automation the real-time data can be transferred to process control systems via 4-20 mA signal, digital outputs, fieldbus or Ethernet. The LiquiSonic® controller displays and saves the measuring values.

The analyzer is delivered as plug&play system, so a simple and fast commissioning is guaranteed.

The LiquiSonic® analyzer by SensoTech
monitors precisely the sulfuric
acid and oleum strength and provides the data online and in real time.
