A process and system for desalting crude oil includes delivering a stream of salty crude oil and wash water into a mixing valve, mixing the stream of salty crude oil and wash water through the mixing valve to create a mixed stream of desalted crude oil and salty wash water, delivering the mixed stream of desalted crude oil and salty wash water to a static mixer, and mixing the mixed stream of crude oil and wash water in the static mixer. Within the static mixer, the mixed stream is mixed in a coalescing regime to coalesce smaller droplets of water into larger droplets of water. The mixed stream is then directed to a desalter where the salty wash water is separated from the desalted crude oil.

A system for desalting crude oil includes delivering a stream of salty crude oil and wash water into a mixing valve, mixing the stream of salty crude oil and wash water through the mixing valve to create a mixed stream of desalted crude oil and salty wash water, delivering the mixed stream of desalted crude oil and salty wash water to a static mixer, and mixing the mixed stream of crude oil and wash water in the static mixer. Within the static mixer, the mixed stream is mixed in a coalescing regime to coalesce smaller droplets of water into larger droplets of water. The mixed stream is subjected to an electric field to cause additional coalescence before being directed to a desalter where the salty wash water is separated from the desalted crude oil.

System and method relates to measuring separation rate of water from water-in-crude oil emulsions at elevated temperature. The system includes an electrolytic interface (conductivity) cell comprising a plurality of capacitance/conductance probes disposed at different heights in a fluid stream disposed within the interface cell and an analyzer. Logic of the analyzer determines the separation rate based on signals received from the plurality of capacitance/conductance probes in the interface cell that are coupled to monitor the fluid stream. Methods for making and using the system are also disclosed.
