Numerical simulation analysis of cone angle effect on the de-sanding performance of hydrocyclone
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 3
Abstract
First, the necessities of produced liquid sand removal in oil-field are introduced, in addition to the structure of the cyclone-desander to study and its basic separation principle are discussed. By using numerical simulation software FLUENT, putting the field produced fluid from certain oilfield as a separate object, we conducted research on numerical simulation of cone angle structure variable for the main diameter value of 56mm cyclone-desander. The distribution and the variation law of the velocity, pressure drop and sand phase volume fraction were obtained. Finally, sand separation efficiency of the different cone angle structure of Hydrocyclones was compared. Research shows that when the cone angle is 5°, the tangential velocity (vt) in the cyclone is maximum, the sand volume fraction distribution in the bottom outlet is the highest, But also accompanied by a larger pressure drop, the sand separation efficiency is up to 96.3%. The conclusions of this paper can be for oilfield produced liquid cyclone-desander structure optimization design provides guidance. Keywords: cone angle, hydrocyclone, desanding, separation performance, numerical simulation
