Abstract

Based on near-infrared spectral absorption and fiber-optic sensor technology, an experimental setup for low-water-content measurement of crude oil is developed. The advantages of this method include fast measurement, high accuracy, keeping the measured oil free of pollution, and being suitable for long-term on-line continuous monitoring. This technology can be used for those applications that require high-quality water-in-oil measurement and process control. The measurement resolution for water content is better than 0.005% in the range from zero to 2% by volume. Measurement errors are estimated to be ±0.01% in the range from zero to 1%.
