Controlling the process optimally and safely requires information provided promptly through a rugged and fast process analytical technology. Using the LiquiSonic® measuring technology and its easy integration into existing plant engineering systems at relatively low project costs enables partly significant improvements of the plant capacity, the process safety or product yields. The LiquiSonic® systems are used in many fields of application particularly in the chemical industry: ·· fast detection of transitions between product and carrier phases (LiquiSonic® 20 or 30) ·· concentration...

Phase separation in the continuous process LiquiSonic® examples for application: ·· silicone resin phases ·· fatty alchol phases in wastewater ·· epoxy resin phases ·· polyether phases ·· gas-liquid phases Compared to conductivity sensors, the LiquiSonic® sensors can also be used in the most different separation processes from aqueous into organic phases or vice versa. The continuous measurement allows to regulate almost any separating ranges within the transition or slurry phases. The trend view of the controller shows directly the signal waveform. At the same time, it is possible to...

Concentration measurement in binary liquids LiquiSonic® systems provide excellent results, for example with the measurement of the following liquids: LiquiSonic® sensors provide clear and temperature compensated concentration values for different process liquids. The following tasks can be fulfilled at relevant steps of process for the concentration measurement: ·· monitoring and identification of delivered products ·· quality control at intermediate products ·· control and monitoring (dilution, concentrating, product infiltration) ·· monitoring the quality of the end product inorganic...

The measuring technology is also suitable for the salt production, for example for the brine extraction or dissolving plants, as well as in downstream processes, such as the chlor dehydrationing with sulfuric acid (H2SO4) and the blending of caustic soda or hydrochloric acid (HCl). Chloralkali electrolysis Both chlorine (Cl2) and caustic soda (NaOH) are one of the most important basic chemicals and produced from sodium chloride (NaCl). Chlorine can also be obtained from potassium chloride (KCl). The chloralkali process uses different electrolytic methods, but the most common types of...

Production of sulfuric acid Sulfuric acid is mostly produced with the contact process, in which elementary sulfur is converted to H2SO4. This sulfur is formed again in great quantities during the flue gas desulfurization in the petrochemistry. In the production process, the LiquiSonic® analyzers are used for the following measuring tasks: ·· monitoring of the concentration in the SO3 absorber to the oleum range ·· monitoring and control of the blending to the required accepted concentration The successful use of LiquiSonic® is not only based on the resistance to corrosion, lack of...

Monitoring of heat exchanger Both shell-and-tube and plate heat exchangers are exposed to varied corrosion influences. In case of breakthroughs between the product and refrigerant cycle, critical process statuses or continuous plant shutdowns can occur, if suddenly process liquids enter in the refrigerant stream or vice versa. LiquiSonic® assures to detect these breakthroughs within seconds. heat transfer liquid Measuring point Measuring task detection of cooling water or break-in of refrigerant into the process liquid detection of contaminations of the cooling water of refrigerant caused...

Multi-component analysis A number of process liquids consists of three main components. Typical examples are: ·· methanol-formaldehyde-water ·· caustic soda-sodium chloride-water ·· hydrochloric acid-iron-water ·· caustic soda-propanol-water The LiquiSonic® 40 system also determines the concentration of each component even in these mixtures of multi-component by using an additional physical quantity. Conductivity sensors are primarily used in this measurement. IAt gas scrubbers and neutralization columns in particular, the continuous monitoring of the concentration of NaOH and NaCl is...

The LiquiSonic® 40 systems are used with success at different measuring points for the process analysis in gas scrubbers. The LiquiSonic® system facilitates separate inline determination of the concentration of the scrubbing solution and salt without any time delay. Hence, it is possible to sharpen the scrubbing liquid in a defined manner and to keep the liquid concentration always in the range of maximum solubility and absorption. Therefore underdosing, i.e. insufficient scrubbing, is avoided as well as overdosing, i.e. excessive input of materials and related costs. Reaction monitoring...
