Demulsification and breaking mechanism of variable quartz concentrates obtained from sand

This study reports the efficacy of quartz particles extracted from sand for the destabilization of crude oil emulsions and efficient water removal. Demulsification performance of quartz concentrates obtained from stacked sieves with openings: 75, 125, 250 and 300 μm and quartz quantity varying from 1% to 7% were investigated using the bottle test technique at a temperature of 90 °C. The breaking mechanism of emulsion driven by quartz was...
