Abstract

In this research, ethanolic extracts of mulberry and mango leaves were evaluated as potential dehydrators of heavy crude oils. The extracts were obtained by maceration with a 70:30 % vol ethanol: water mixture. The effectiveness was determined using several aqueous emulsions, W/O, from 10 to 40% by volume, of heavy crudes, Hamaca and Jobo type, from the Orinoco Oil Belt. The emulsions were dosed with 100, 500, 1000, 1000, 1500 and 2000 µL/L of the ethanolic extract, shaken, centrifuged and the phases separated. The results showed that the blackberry and mango demulsifiers have great affinity for dehydrating heavy crude oils. The mango extract presented greater efficiency in breaking emulsions, W/O, of Jobo crude oil, while the mulberry extract for Hamaca crude oil.
