A Field Comparison of Static and Dynamic Hydrocyclones

Abstract

Summary Three commercially available liquid/liquid hydrocyclones (LLHC's) are evaluated in an operating oil field. The oil-removal capabilities of two staticunits and one dynamic or rotating unit are determined across a full range of operating conditions. Such variables as driving pressure, flow rate, rejectrate. and rotational speed are investigated to optimize oil-removal efficiency. The key parameter of oil droplet-size distribution also is evaluated and itseffects on performance are determined.
