(5d) Hydroclyclone Experiments and Design Equations for Produced Water Desanding Operation
In this work, we present the experimental results on a series of tests carried out on a purposely-made pilot unit hosting a single hydro cyclone and able to work at water flow rates up to 2.5 L s-1. The setup is able to set independently the feed flow rate and the underflow flow rate. Mixtures of water and Tri-hydrate Alumina particles (1 to 70 Î¼m size) up to 2000 ppm v/v of solid concentrations have been tested. Solid particle density, particle size distribution and shape makes the tested system very similar to real water sand mixtures in produced water desanding operation. These results have been used to find the proper hydrocyclone design equation such as those proposed by Coelho and Medronho . In particular, we have found the proper correlations for the cyclone pressure drops, and the cyclone cut size as a function of the liquid flow rate and the water flow ratio between the underflow and the feed stream.
