Measuring liquid concentration to control and optimize chemical industry operations
Measuring liquid concentration or density in-line is important in the chemical industry as density variations have impact on both raw materials and finished products. Process safety is also mandatory, since hazardous chemicals represent a potential risk to people and the environment. While managing these challenges, chemical manufacturers strive to produce high-quality products that meet customers’ specifications. To achieve these goals, accurate process measurements, high process efficiency, low energy consumption, and state-of-the-art process control management are crucial.
Vaisala K-PATENTS® process refractometer is designed to measure and indicate inline liquid concentration of almost any chemical or compound.
The refractometer can be installed cost-efficiently in the main processing line, bypass line or vessel to control the raw and in-process materials in order to extract their maximum value and achieve high quality end products. The performance of all types of chemical refining, manufacturing, and quality-control operations can be dramatically improved with Vaisala’s refractive index measurement technology – whether they are in continuous or batch processes.
Unlike intermittent sampling, continuous monitoring provides instant feedback on changes in the process, and this data can enable real-time and precise process control of the common chemical industry operations, e.g.:
Using the Vaisala concentration measurement technique and its easy integration into plant engineering systems enables significant improvements in the plant capacity, the process safety or product yields.
In this eBook we review two most widely used methods of liquid concentration measurement, i.e. refractive index technology (refractometer) and density (Coriolis, ultrasonic, nuclear, and microwave).
When choosing the best measurement solution for your process, consider the following aspects: process conditions, installation options, environmental impact, measurement accuracy, and the overall cost of the solution ownership.

Vaisala K-PATENTS® process refractometer offers accuracy, repeatability and reliability even in the most extreme environments that can be corrosive or abrasive, subject to chemically aggressive solutions, extreme temperatures, pressures, vibration or contamination, humidity and dust, or any combinations of these factors.
Vaisala is specialized in in-line process refractometers and optical process analyzers for refractive index-based concentration measurements. Vaisala instruments range from compact probe models for small pipeline and bypass lines to rugged heavy-duty long probe versions for large pipeline, vessel and reactor installations. When standard models are not sufficient to fulfil requirements, please consult the factory for engineered solutions, e.g. special wetted materials or custom mounting accessories and process connections.
Vaisala also provides full range of start-up, commissioning and technical support services to our customers. Our industry expertise includes supply of extensive vendor documentation that is tailored and applied to each contract and client specific data. Local authorized distributors have extensive applications knowledge and they can help to specify the correct instrument for each application requirements.
