An experimental and theoretical study was carried out regarding the evolution of droplet size distributions for the flow of water in oil emulsions through a valve-like element that simulates a mixing valve. The water droplets had diameters in the 0.1

In this work, a novel procedure is developed to determine the amount of salt for crude oils in which the available laboratory techniques are unable to provide accurate salt content values. The technique is based on measuring the salinity of the wash
