| abstract |
MONITORING AND CONTROLLING HYDROPHOBIC COMPONENTS IN A PULP PROCESS.nThe present invention relates to a sample of an aqueous stream, which is led to an optical measuring device. A hydrophobic dye is added. The sample is fractionated into fractions, according to particle size or mass. Fluorescence intensity values, and light scattering intensity values for the fractions are measured. The fluorescence intensity values of the fractions are added together, thereby obtaining a sum of the fluorescence intensity values. The light scattering intensity values of the fractions are added together, thereby obtaining a sum of the light scattering intensity values. A hydrophobicity density of the particles in the sample is calculated by dividing the sum of the fluorescence intensity values by the sum of the light scattering intensity values, and the concentration of hydrophobic contaminants in the aqueous stream is monitored and controlled, based on the density. of calculated hydrophobicity of the particles in the sample. |
