Abstract
An automated system and method for measuring the residence time of wood pulp as it moves through various stages of processing in a pulp mill. A tracer compound comprising a neutral salt of a halogen is introduced into a first location in the path of the pulp slurry; at a second location an automated detector detects the concentration of tracer compound over a time period; a controller relays a voltage signal from the detector to a processor which uses a calibration curve to integrate tracer concentration over time and thereby derive pulp residence, between the first and second locations.
