Black liquor concentration testing in the paper industry
ATAGO online concentration meters CM-800a and PRM-100a for monitoring black liquor and green liquor in the paper industry
The refractometer has long been proven to be suitable for the detection of black solids content. A linear change in refractive index relative to the concentration of black liquor makes measuring concentrations relatively easy and precise. The refractometer measures the true solids content without being affected by air bubbles, entrained air or suspended matter. This microprocessor-based, easy-to-use design allows you to easily integrate your refractometer into your monitoring and/or control system.
An important area of ​​refractometer application is the pulp washing operation. By monitoring the concentration at the outlet of the scrubber to meet the needs of the evaporator process. This type of application is very convenient to install and greatly reduces the amount of manual sampling. In the evaporator, the concentration and temperature output signals can be used to monitor evaporation efficiency, detect problems, and economics of operation. The concentrated concentrated black liquor must be tested for solid content (concentration) before entering the storage tank and the alkali furnace to ensure the safety of the operator and the alkali furnace.
ATAGO online concentration meters can be installed in the paper industry inspection points are:
1) The output of each pulp washing device can monitor the efficiency of the washing operation
2) Concentration between evaporators
3) The concentration of the diluted liquid entering the evaporator
4) Evaporator output to concentrated black liquor storage tank
5) From the black liquor from the storage device to the alkali furnace
ATAGO online concentration meter pipe adapter has its own high-pressure water flushing pipeline to ensure that the measurement results will not be affected by the adhesion of impurities and particles to the instrument prism during the paper production process, nor should the measured medium be darker or have more bubbles. The drift phenomenon makes the measured value true and effective.
In order to be able to measure various types of aqueous solution concentrations (dilution) simultaneously by Brix values, the ATAGO refractometer is capable of directly displaying the concentration value on the screen. There are over 80 special scales to choose from.
