SHIPBOARD OIL-IN-WATER-CONTENT MONITOR BASED ON LIGHT-SCATTERING AT 45 DEG., 90 DEG. AND 135. DEG. AND TURBIDITY AT 0 DEG.
A breadboard oil-in-water content monitor for shipboard applications was designed and assembled. An evaluation followed using various oil mixtures for the test medium. The oil-in-water monitor consists of (a) a sample handling system for homogenizing the oil, and (b) a unique multiangle scattered-light and turbidity sensor. The monitor response is linear from 0 to more than 125 ppm oil concentration. The response time is less than 10 seconds. The breadboard is equipped with four light-emitting diode sources and four photovoltaic detectors for high reliability and low maintenance, for compensation of drift effects and for reduction of deviation of response to different oil mixtures. Deviations of response of the monitor for oil in the presence of solids and detergents and at different salinities, temperatures, and pH's were obtained and are discussed. Recommendations for a field prototype instrument are presented.
