Abstract
Method and apparatus for continuous measurement and control of the stability of colloidal systems such as heavy fuel oils, using an optical procedure with near-infrared radiation. A stream of liquid representing the colloidal system is passed through a loop or elongated conduit. In the latter, measured amounts of a flocculating agent is progressively added to the stream at a series of spaced apart stations in the loop which define separate segments. These additions progressively enhance the amount of flocculating agent to the colloidal liquid to a point where flocculation occurs. The character of each segment of the loop is tested by irradiation whereby the mixture in each segment is measured to determine in which segment flocculation has commenced. A suitable signal, whether audible or visual, can then be provided to indicate the occurrence.
