As mentioned above, online water analyzers for crude oil do not actually perform that well. For online water analysis of crude oil, electromagnetic spectroscopy or capacitance methods (based on dielectric properties) are commonly used. However, the principles behind these two methods mean that they are not very effective for complex substances like crude oil, as there are too many factors that can interfere with the measurements. These water analyzers may perform very well during offline calibration, but once they are in operation online, it may not take long before data fluctuations or even unacceptable deviations occur, as there are many factors that affect crude oil as it enters the atmospheric and vacuum distillation units. First is the type of crude oil, followed by the impact of various additives used in its extraction, storage, transportation, as well as during secondary separation and injection processes. There is also the influence of flow velocity and flow conditions, as well as temperature, plus the effect of surrounding electromagnetic fields. To make good use of online crude oil water analyzers, it is important to control the measurement conditions, select appropriate measurement locations, and maintain constant flow rates and temperatures. Additionally, it is necessary to gather correction data for different types of crude oil in order to make proper adjustments to the measured values.
