Process Analytical Technology for Concentration Measurement, Phase Separation and Reaction Monitoring

In industrial processes, inline analytical technology is used to monitor critical parameters and to control processes for quality assurance, production efficiency and safety. This increases process reliability, reduces costs of raw material and energy, and  eliminates failed productions.

With the LiquiSonic analytical technology of SensoTech (Germany), parameters such as the concentration in process liquids can be monitored. The analyser is used in almost any liquids of the chemical and pharmaceutical industry, food production, semiconductor technology, metal production and many more industries. For example, in the chemical industry the LiquiSonic sensors measure the concentration of sulphuric acid, ammonia, hydrofluoric acid and more chemicals. In  the chlor-alkali electrolysis, the analyser monitors sodium hydroxide, sodium chloride, hydrochloric acid and sulphuric acid. Also in gas scrubbers, phase separations, neutralisations, dissolvings or blendings, the LiquiSonic sensors are integrated into the process. In addition, the analyser monitors complex reactions such as crystallisations or polymerisations. In crystallisations, critical parameters include the saturation degree, the crystal content or the metastable range, whereas in polymerisations the analysis of the polymerisation degree is important.

The LiquiSonic technology is based on sonic velocity measurement that provides high-precision and stable measuring results being updated every second. Compared to other measuring methods, sonic velocity devices are extremely robust and maintenance-free, corrosion-resistant by using special materials, and integrable into the process without bypass. LiquiSonic sensors, made in Germany, are installed directly into pipes of any size or into vessels. The measurment is continuously inline and the results are provided online. The LiquiSonic controller displays and stores the results. The trend view shows the process status at any time. If the measuring result exceed or fall below thresholds, a signal will be sent immediately. For automated process control, the measuring results can be transferred to the process control system. Via a PC-interface, it is possible to read all data and to create reports and protocols.
