Emulsification of oilwater secondary dispersions by using centrifugal pump

Abstract EN

The present work is concerned with secondary Oil/Water dispersions.

A simple, but effective, method of producing secondary dispersions continuously is to pass the bulk phases through a centrifugal pump with by-pass circuit.

The Oil/Water secondary dispersions produced by the centrifugal pump (e.g.

a Stuart Turner No.

12 Stainless steel centrifugal pump with maximum flow rate of 54.1 liters / minute) were analyzed at regular intervals during an experiment to the drop size distribution.

New techniques that were developed for measurement of drop size distribution of secondary dispersions using Laser Particle Size Analyzer, which consisted of (He / Ne) laser emitter and laser receiver and lenses.

The Laser Particle Size Analyzer was fixed directly to the experimental equipment by using the special designed circular cell.

The measurement of drop size distribution was done by a computer system with application of a software package.

The new mean drop diameter (i.e.

d2i) equation has been derived theoretically and the results that have been predicted there from this equation exhibited a maximum error of ± 15 % from the experimental data.
