DEVELOPMENT AND TEST OF A SHIPBOARD, CONTINUOUS, ON-LINE OIL-IN-WATER CONTENT MONITOR USING FORWARD (LASER) LIGHT-SCATTERING TECHNIQUES

The oil-in-water monitor described here employs solids separation, pressurization and a light-scattering discrimination technique such that normal errors caused by solids, air (gas), bacteria, plankton, and varying types or mixtures of oil are reduced or removed to acceptable low levels. A simplification of the laser beam diffraction pattern intensity and the oil particle diffraction scatter intensity theories is shown diagramatically. Test results show that the concept is able to detect 0-100 ppm of a wide variety of oils and mixtures with response time of less than 10 seconds with each step change in the flowing stream.
