| Abstract: | A simplified equation relating water droplet size distribution to crystallization temperature, determined from differential
scanning calorimetry (DSC) curves of aqueous emulsions of petroleum is reported in this article. A series of water-in-oil
(W/O) emulsions was prepared by dispersion of water in different Mexican crude oils; in a classical DSC experiment, these
emulsions were submitted to a regular heating and cooling cycle within temperatures including freezing and heating of dispersed
water. The Z-average diameters of the water drops (D
dz) were estimated this way and correlated with petroleum composition. |
