This presentation will discuss a modified two-parameter methodology in which the minimum droplet size that can be created from available energy along with the maximum droplet size that can survive in the flow are used to characterize the droplet size distribution. Evaluations of this methodology over a range of dispersion suggest that the approach can be universally applied to dispersions of liquid in gas, liquid in liquid, and gas in liquid.Increasing costs associated with separators - often in difficult, remote applications - drives the desire to improve separator selection and avoid oversizing the device by improving confidence in separator performance predictions.
