Long term monitoring of recovery cycle
It is important for pulp mills to assess certain black liquor characteristics at regular intervals. This way, in the event of disturbances, there is sufficient reference data available on the so-called "good liquors" which have not resulted in any major problems.
To maximize the benefits of the analyses data, the same characteristics should be analyzed repeatedly. Cause of closed water cycles the enrichment of a certain substance or compound in the chemical circulation increases. The process can be modified if the enrichment can be detected at an early stage.
We have compiled the most important black liquor analyses into two packages: a basic package and an evaporation plant and combustion package.
It is designed to be performed at regular intervals (4-6 times per year), even if the black liquor is good and the mill does not have any problems with it.
Evaporation plant and combustion package
The measurements in this package are important for the operation of an evaporation plant and the recovery boiler. These measurements are performed according to need, in addition to the basic package. However, it is not necessary to complete the evaporation plant and combustion package as often as the basic package.
