Sachtleben Pigments relies on Kemotron technology

Sachtleben Pigments Oy is a producer of specialty pigments. Its production process requires sulphuric acid (H2SO4), which is produced in its own sulphuric acid plant. Producing sulphuric acid is a complex process. To operate at an optimum level, the acid concentration has to be kept at fixed pre-set values through continuous online measurements. The plant has relied on the Kemotron technology since the mid-1990s.

The process can be run reliably only if it is based on reliable measurements. Process reliability enables us to make the best possible end product.”

Summary
Location Pori, Finland
Customer
challenge

Producing sulphuric acid is a complex process. To operate at an optimum level, the acid concentration has to be kept at fixed pre-set values through continuous online measurements. Reliability and high availability are key factors in running a demanding sulphuric acid process. At Sachtleben, the sensors are located outdoors.

Solution

Inline concentration measurement that gives accurate online process information and is designed to withstand even the harshest conditions.

Results

Reliable information helps to control the other parts of the process. To ensure reliability, the measurements
are checked once a week against laboratory test results. Calibration is hardly ever needed.
