APPLICATIONS WEAK LIQUOR FROM PULP WASHERS Black liquor concentration is measured with K-Patents Process Refractometer to optimize the consumption of pulp chemicals and usage of water in the washing. The material balances can be calculated and the efciency of the washing process can be maximized. BLACK LIQUOR TO EVAPORATORS The concentration of feed liquor from washers to evaporation can be kept constant by controlling the mixing liquor with the K-Patents Process Refractometer, thus allowing the capacity of the evaporators to be maximized. Using K-Patents in the intermediate stage the protability...

SAFE-DRIVETM SYSTEM CORE-OPTICS K-Patents SAFE-DRIVETM Process Refractometer PR-23-SD is a complete heavyduty system for measuring black liquor dry solids % b.w. in kraft chemical pulp mills. K-Patents SAFE-DRIVETM Process Refractometer system consists of: All SAFE-DRIVETM Sensor's measuring components (light source, prism, temperature sensor and CCD-camera) are in one solid CORE-optics module. The patented CORE-optics is mechanically isolated from the inuence of external forces such as temperature shocks, pressure peaks and vibration (US Patent No. 6067151). Therefore, the CORE-optics module...

DIGITAL MEASUREMENT PRINCIPLE ETHERNET SOLUTION Optical image Prism Light source Critical angle Process medium The light source sends light against the interface between a prism and the process solution, where the rays meet the surface at different angles. Prism Reected light Cr itic al an gl e Light source The angle corresponding to the shadow line is called the Critical angle of Total Reection. The Critical angle is a function of the refractive index and therefore the concentration of the solution. Solution Refracted light Depending on the angle, some rays are totally reected. Some rays are...
