Abstract
The development of a pulsed photoacoustic instrument for the detection of crude oil concentrations in produced water is reported. The instrument utilizes fiber-optic delivery of pulsed diode laser sources to an in-line sensor head, incorporating a gradient-index lens for optical delivery into the flow line and a piezoelectric transducer for acoustic detection. A crude oil concentration detection range of 5-8000 parts per million in water is demonstrated. The sensitivity of response was confirmed during preliminary field testing and is independent of various interfering analytes, flow rate, and droplet size.
