On-line sensor for colloidal substances |
| abstract |
A method and apparatus for determining and controlling a property of colloidal substances that undergo at least one of a temperature dependent phase transition and a temperature dependent adsorption-desorption process is disclosed. The colloidal particles are characterized by performing successive measurements of light attenuation or emission by a colloidal mixture at two or more temperatures and at one or more wavelength. The difference or ratio of the measurements at two or more temperatures provides a measure of the colloidal stability with respect to temperature. The amount of certain organic colloids that are unstable to temperature variation may be determined from the magnitude of the measurement change. This method may be specifically applied to determining the tackiness and propensity to deposit of colloidal pitch or wood resin in pulp or paper process water as an indication of the effectiveness of a chemical control program. In this context a feedback signal may be provided for use by a process controller to achieve improved process control. |
