RODRIGUEZ TARRAGO, Héctor Luis; FALCON HERNANDEZ, José  and  ANGULO PALMA, Hugo Javier. Rheological behavior of the emulsions using pyrolysis products. RTQ [online]. 2015, vol.35, n.3, pp. 343-353. ISSN 2224-6185.

This paper contains the results of the rheology of water emulsions of Cuban crude petroleum PE and HE, employing emulsifier agent EM-10 prepared with pyrolysis products of sugar cane straw or bagasse In the same emulsion formulations were analyzed and determined the rheological behavior to prepare, and then spend 24 hours standby. The investigation confirmed that the crude PE and HE remain a newtonian rheology with a viscosity of 33,104 Pa.s and 28.733 respectively, while all the emulsions were obtained with a pseudoplastic rheological behaviour, Lower values of viscosities at 1 Pa.s, even after being reconstituted after 24 hours of rest, with best results obtained in the two relationships that had 60% of the crude petroleum sed. The work confirmed that the emulsion prepared with emulsifier ying agent EM-10 presents the stability conditions for transport by pipeline, this emulsifier having a well highly effective when crude petroleum of viscosity between 28 and 33 Pa.s is used.

Keywords : emulsion; emulsifier; rheology; viscosity.
