Abstract
The impact of mixing on demulsifier performance is studied using image analysis. Three experimental campaigns based on fractional factorial designs were performed in a CIST (Confined Impeller Stirred Tank), varying demulsifier bulk concentration (BC) and injection concentration (IC), mixing time (tm) and mixing intensity (). The first campaign shows that BC and IC had significant effects on demulsifier performance and that tm and  were insignificant. The second campaign shows that mixing had a much more significant effect when the BC and IC are at the optimal values. The last campaign showed that good mixing is a solution for overdosing of a system.
