Why inline measurement?
- Improved control through continuous measurement
- Less manual sampling
- Reduced risk of exposure to formalin for operators
All continuous processes experience variations. Variations can be induced by operators and setpoint changes, but also by dynamic phenomena in the process, external changes and variations up- and downstream.
To ensure that the product is witin specifications, it is vitally important to regularly measure the content of the product stream. This is commonly done by manual sampling once per shift. Such a low sampling frequency gives little insight in the process' dynamics. Inline measurement allows for continuous measurement, which gives full insight and enhances process control.
The need for manual sampling is significantly reduced, leading to less workload for the operators and reduced risk of exposure to formalin. Occasional manual sampling is recommended to validate the sensor and is needed when the concentration is outside the measuring range.
Proven technology
In 2021 Dynea started investigating possible measurement principles. After a careful review of available sensors, one sensor proved to be particularly attractive due to its high accuracy and cost-effectiveness. The sensor was installed in May 2022 at Dynea Lillestrøm in Norway. Installation was straightforward and the sensor has been operating successfully and maintenance free since installation.
By applying Dynea's adjustment factors, the sensor performs within the stated accuracy. The reliability has been verified over a 1.5 years period. Dynea has obtained approval of the authoritites to use the inline measurement as method for environmental reporting and GMP certification.
Dynea now offers this technology as a complete package to fasil® licensees, such that they can benefit from the knowledge Dynea has acquired and enjoy a smooth implementation of continuous measurement of the product composition.
