Abstract : Conceptual studies were performed of various measurement techniques to monitor oil in water. The objective was to define a prototype instrument system capable of continuously monitoring a water discharge line which may contain crude or refined petroleum products. A literature search was performed to determine measurement techniques. An evaluation of performance data from the literature was performed in terms of how feasible a particular instrument or technique was in meeting the requirements of this project. Most instruments were capable of performing the basic oil measurement; however, the sample preprocessing was performed manually, leaving the problems of sample acquisition, sample size, dilution effects, contamination, transport ime, carry-over contamination, etc., unresolved. Conceptual studies were redirected to consider the total system, an instrument capable of continuous monitoring, unattended, to measure total oil. Basic measurements of probable oil contaminants were performed with: Navy Special Fuel Oil, JP-5 jet fuel, lubricating oil, hydraulic oil, and No. 2 Fuel Oil. Measurements of the most likely sensing technique were performed. These included total organic carbon, infrared absorption, ultraviolet absorption, fluorescence, gas chromatrography, and simulated distillation of the oil products. The specificity and dynamic range of each technique was evaluated with the sample acquisition and conditioning requirements. The most feasible systems were: Sample solvent extraction with NDIR analysis, and sample pyrolysis with flame ionization detection. (Author)
