Method and system for the separation intensive of heavy oil by granulation of residue of asphalt after extraction coupled.

摘要

The present invention relates to a process and a separation system where the granulation of a residue of asphalt after extraction coupled is used to obtain the separation intensive of a heavy oil. A solvent for dispersion is introduced into the phase of asphalt after separation by solvent extraction (02) and the phase of asphalt undergoes a phase change rapidly in a separator gas - solid (07) and is dispersed in the solid particles while the solvent becomes a gas, which leads to a separation at low temperature of the asphalt and the solvent, the size of the asphalt particles being adjustable. The method and system of the invention, use the atmospheric pressure and a separator gas - solid at low temperature at the place of a furnace at high temperature and high pressure and does not require the preheating of the load or a device for the exchange of heat to the input of the separation column of resin (04), which leads to a simplified process and a reduced investment.
