This invention provides a process for obtaining, under low pressure conditions, a highly stable, homogeneous hydrocarbon with low viscosity and high retention of volatiles. The hydrocarbon resulting from the process is composed mainly of heavy and extra heavy crude oil, a conventional diluent and a NCD, wherein the components of the NCD are grouped into three types: hydrocarbons with three or less carbon atoms (C-3), hydrocarbons with four carbon atoms (C4) and hydrocarbons with five or more carbon atoms (C5+). The mixture of the defined components has a synergistic effect on the viscosity, stability and homogeneity properties of the final hydrocarbon, making it possible to transport the heavy and extra heavy crude oil which originally has an API between 7 and 25. |
