Shipboard Oil-in-Water Content Monitor Based on Light Scattering at Ninety Degrees

摘要

An oil-in-water monitor breadboard for shipboard applications was designed, assembled and evaluated with various types of oils mixed with tap water, salt water, acidified water and water containing suspended solids. The oil-in-water monitor consists of (a) sample handling system designed to remove suspended solids from the sample stream and to homogenize the oil to uniform droplet size ranges, and (b) a unique nonfouling scattered light sensor. The monitor response is linear from 0 to 200 ppm oil concentration.
