Abstract

Oil detection methods in discharge water are based either on chemical analysis of intermittent samples or on bypass pipelines with instrumentation to detect hydrocarbons by a variety of optical techniques. Tests have shown that no single instrument entirely meets present needs or satisfies the requirements of more stringent future legislation. To meet this need and develop a new generation of systems for environmental monitoring, a novel type of instrumentation is being developed based on the photoacoustic technique. The instrument is designed primarily for the monitoring of oil in process water but may also find application in oil detection in the open sea and in the detection of oil and other pollutants in rivers, estuaries, lochs and sewages.
